I have been following this video to install the linkage between postgreSQL and C++ (https://www.youtube.com/watch?v=qDiC1Wja6Og), and after following all the steps, i get this error: "The code execution cannot proceed because LIBPQ.dll was not found." even though i went into the postgreSQL directory and found the file. I have no clue how to fix it, i've tried reinstalling postgres and i've restarted my pc each time it was needed. Any clues or solutions would be appreciated thanks
Try put libpq.dll into directory of your project build also you need to add
libeay32.dll,
libiconv-2.dll and
libintl-8.dll.
You can take all these libraries from Postgres installation
|---app.exe
|---libpq.dll
|---libeay32.dll
|---libiconv-2.dll
|---libintl-8.dll
or add path to libpq.dll into the path environment of your os
I've just installed SQL Developer 4.1.1 64-bit on a Windows Vista machine, in directory c:\sqldeveloper.
My Java installation is in c:\program files\java and I have two sub- directories:
c:\program files\java\jdk1.8.0_31
c:\program files\java\jdk1.8.0_25
I have modified the jdf.conf and sqldeveloper.conf files in the
c/sqldeveloper/sqldeveloper/bin directory. jdf.conf was empty and I added the following line:
SetJavaHome
c:\program files\java\jdk1.8.0_31
sqldeveloper.conf:
#SetJavaHome ../../jdk <===== This is what is was
SetJavaHome c:/program files/java/jdk1.8.0_31 <======= I changed it to this
I even moved the missing file "msvcr100.dll" it was asking for to the c:/sqldeveloper/sqldeveloper/bin directory.
I got the following error messages:
This application has failed to start because msvcr100.dll was not found.
Re-installing this application may fix this problem
Unable to launch the java virtual machine located at path
c:\sqldeveloper\jdk\jre\bin\server\jvm.dll
The file msvcr100.dll is in the Java directory c:/program files/java/jdk1.8.0_31/bin.
The file jvm.dll is in the Java directory
c:/program files/java/jdk1.8.0_31/bin/jre/bin/server.
I modified product.conf:
#SetJavaHome /path/jdk <===== This is what it was
SetJavaHome C:/Program Files/Java/jdk1.8.0_31 <====== This is what I changed it to
I have a copy of msvcr100.dll in sqldeveloper/sqldeveloper/bin folder and in the c:/program files/java/jdk1.8.0_31/bin folder.
To run SQL Developer I click on sqldeveloper.exe in the c:/sqldeveloper/sqldeveloper/bin directory.
Is I am running it on the correct way?
I ran in to the same problem myself, trying to run SQL Developer 4.1.1 64-bit with JDK on a Windows Server 2008. I've installed SQL Developer many times over the years from 1.x to 4.1.1 and never encountered this until now.
I solved it by copying the MSVCR100.dll file from sqldeveloper\jdk\jre\bin to the sqldeveloper\sqldeveloper\bin folder.
Update 3/18/2017:
In downloading the latest version from Oracle's website, I found this in the installation notes which confirms and explains the issue:
Note: the Windows EXE requires a MSVCR100.dll to run. Most computers will already have this file and in the Windows PATH. However, if the first copy of the file found by the EXE is a 32-bit copy of the DLL, then SQL Developer will fail to start. You can fix this by copying a 64-bit version of the DLL into the BIN directory or updating your OS PATH such that a 64 bit copy of the DLL is found first.
Only create the directory /sqldeveloper/jdk/bin and copy The file msvcr100.dll is in the directory.
Then /bin don't exist is in the /sqldeveloper/jdk
I have faced this similar issue on my local system.
I have solved this issue by copying bin directory from insatallation_directory/jdk/jre to insatallation_directory/jdk/
You need to copy the msvcr100.dll file from sqldeveloper/jdk/jre/bin/msvcr100.dll to sqldeveloper/sqldeveloper/bin/. Then just open SQL Developer again.
You only need to create the directory \bin in sqldeveloper \sqldeveloper\jdk\bin and copy the msvcr100.dll file in this new directory.
Got the same issue with newest versions.
Interestingly enough, msvcr100.dll is present in JRE 1.8.0_251, but not in JRE included in JDK 1.8.0_261.
Even though I run SQL Developer with included JDK, it tried to use my installed JRE 1.8.0_261.
Resolution was simply to copy missing msvcr100.dll from any other place (like jre1.8.0_251\bin or maybe even Windows/System32) to the JRE used by SQL Developer. In my case to jdk1.8.0_261\jre\bin.
I'm trying to get Eclipse to work on my CentOS 7 VM via X11 forwarding. The X11 forwarding seems to be working, as I am able to run and see "xclock". However, whenever I run Eclipse, it crashes with a message similar to this:
java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
/home/centos/eclipse/configuration/org.eclipse.osgi/375/0/.cp/libswt-pi-gtk-4527.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory
no swt-pi-gtk in java.library.path
/home/centos/.swt/lib/linux/x86_64/libswt-pi-gtk-4527.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory
Can't load library: /home/centos/.swt/lib/linux/x86_64/libswt-pi-gtk.so
This issue is all over the web, and a lot of it is solved my soft linking files in /usr/lib/jni/ to ~/.swt/lib/linux/x86/ but, I do not have a a /usr/lib/jni directory. So, I tried to find the libraries that create this folder upon installation and I found these in another Stack Overflow post: libswt-gtk-3-jni, libswt-gtk-3-java
And I can't seem to find anything on CentOS that provides these. I then found this guide on the CentOS client portal for installing Eclipse and it doesn't work for me. It talks about getting access to devtoolset-3 via RedHat Subscription Manager or RHN Classic, both of which are unavailable to me on the machine that I am working with.
At this point I have JDK installed, and Eclipse untarred and attempting to launch and I'm getting this error. Any ideas?
I had Eclipse Indigo installed on my computer with the Android plugin and it was working perfectly for about two weeks. Today, I updated java and quicktime then restarted my computer. When it booted back up, eclipse had completely vanished - all the program files have completely disappeared. When I try to reinstall it, I get an error message that says
The Eclipse executable launcher was unable to locate its companion shared library.
What happened and how can I fix it?
I've just encountered the same issue. The problem for me was Windows 7 default unzipper program. It has a problem when it encounters files that have a deep file structure. I read about this issue some time ago but can't recall the article. Fix for me is to unzip the Eclipse download using WinZip (or some other tool which does'nt have this issue).
Check eclipse.ini, there are two entries like:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120913-144807
For some twisted reason jars have version in their name - so if you upgrade/have two different version of eclipse( while eclipse.ini is either linked or provided as system wide conf file for eclipse ) it will cause above error.
That sounds pretty bad and weird. But reinstalling isn't that hard - download, unzip, change the default memory allocation, run Eclipse, install necessary plugins and features.
And almost all of the important preferences are in your workspace. The only important one I can think of outside of the workspace is the aforementioned memory allocation, which you can set on the command line or in the ECLIPSE.INI file.
During unzip in a cygwin directory on Win7, .exe and .dll need to be given executable mode. This is the solution from a mintty (or other $TERM) terminal run with cygwin on windows 7:
me#mymachine ~/eclipse
$ find . -name "*.dll" -exec chmod +x {} \;
tried with Juno (eclipse 4.2) freshly unzipped, cygwin 1.7.something
I have seen this in MacOS Sierra. Sometimes unzipping the app leaves extended attributes that seem to prevent the startup. The following command line removes extended attributes and seems to fix the problem:
xattr -c Eclipse.app
It also works for other applications that are built on the eclipse framework.
Another problem (that I ran into) is that Cygwin's unzip utility (UnZip 6.00 of 20 April 2009, by Cygwin. Original by Info-ZIP.) does not always correctly unzip everything needed for Eclipse to actually run.
Using 7ZIP v9.20 got Eclipse Indigo (3.7.2) up and running for me on Win7 64bit with 32bit JVM and 32bit Eclipse.
(First time I've ever had Cygwin's unzip fail on me...)
I just ran into this myself and found that, indeed, as one post above stated: using cygwin and gunzip or unzip to set up your eclipse environment the permissions on the .exe and .dll files will be incorrect and the JVM will not run them properly.
Quick solution:
#switch to the eclipse target folder
cd /cygdrive/c/Program\ Files\ \(x86\) #or wherever you put eclipse
find ./ -regextype posix-extended -mindepth 1 -type f -regex ".*\.exe|.*\.dll" |\
xargs chmod -v 750
I meet this issue after copy a eclipse installation to another pc.I find the eclipse installation auto created the .p2 directory on my c:\Users\xx.p2, and --launcher.library refer to here.So it doesn't exist on my another pc.
My resolution is to reinstall eclipse:
a)Double click eclipse-inst-win64.exe
b)Click to change to advanced mode.
c)Uncheck the Bundle Pool
d)Finish your installation and copy again.Everything will work well.
My experience and advice: Install Eclipse Juno on C: drive.
After download the zip, put it on C:, click the right mouse button -> extract here. Then a folder called eclipse will be created in C: drive.
Then go to Eclipse executable, run it, and all will be ok.
I faced this problem and solved it by running Eclipse as admin.
Problem happened when I unzipped using Cygwin. Used the Windows XP standard unzip program and it worked.
if you are having two eclipse then sometime this happens
you only have to remove
-startup
plugins\org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar
from eclipse.ini file beside eclipse.exe(Launcher)
Also see this related question's answer.
The gist is: Try unzipping it again with a solid unzip tool. Sometimes unzipping goes wrong, especially with the built-in Windows Explorer tool.
i have this error message when i use extract the files as follows:
action\select all
drag and drow the files to an new folder
Somehow information about the folders get lost
when i use "action\extract to..." it works.
Also, remember to right click on eclipse, then choose Security Unblock
Mostly this is related to problems on windows with the unzipping it seems. (See other answers here for that).
The second largest issue seems to be that eclipse is not able to find java or finds a java version which is too old or even older eclipse installations.
Here's another take to the latter problem and a small twist to solve it. My work environment is on a linux system, without root access, and with software installations where I can configure which versions to use in a kind of config file. However I have no influence on the way those software packages are installed and they are immutable to me.
I download and untar the latest eclipse as usual to a user disk for which I have write permissions. Then I configure myself an alias to always temporarily cd into the eclipse installation when starting. That regardless of where I work on the file systems, eclipse always finds its correct libraries. It seems in some places, eclipses default search path for java digs out an installation (of java or older eclipses or sth else) in my environment that it really should not use.
Here's the alias:
alias eclipse '(pushd /enter_path_to_eclipse_install_dir_here/eclipse ; ./eclipse ; popd)'
Now you can start it normally from e.g. your project or arbitrary work directory:
eclipse
Or also put it in the background
eclipse &
Maybe this helps for people in convoluted work environments.
Try running eclipse.exe as administrator or using Eclipse Helios.
I have copied the Eclipse folder from another machine where the path was different and that was the root of this problem. Changing the plugins path in ECLIPSE.INI worked for me !!
Solution for Mac
Reason:
Eclipse copies from one location to other
Solution:
Paths change needed in /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse.ini
Fix path for plugins\org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar
I had the same problem when I was trying to install it on Windows 8.
But it was an zip composed file....
Ones I unzip and Run "eclipes.exe" file as run As 'Administrator' it was resolved.
Now I am enjoying it very well.
I had the same message after a system restore with the eclipse folder (V. 3/2020) being located on a second drive (that was NOT restored at the same time, I use it for large files mainly).
Restoring the faulty installations C:\Users<user>.p2 folder to the new installation (referenced in eclipse.ini of the eclipse folder) worked.
Keep shorter folder name, fixed for me.
I faced this issue recently: (In my case it was installation of STM32CubeMX software):
what I faced: I have two users in my laptop, I had installed the software in one user but on the hard disk partition: D:\
Now I had tried to work on another user!
-- I think you know why I got the error --
So as I was working on the 'other' user account, I got this error every time I tried to compile/build my project - obviously, Because I installed using one user and am working on another.
Workaround: Already mentioned in the above answers clearly!
What I did differently: I tried using the S/W in the other user, but there seems to be issues on the path file/location:
so I reinstalled the location in the user account I want to use and am running it properly now!
Note: While Installing it did ask about installing the software for all user/ current user : I mistakenly had given 'current - user' =(
I also faced ths problem, I just deleted the extracted file and extracted it again.
I have a .rar file.
This problem occurs when the file is not extracted completely.
You might changed your drive-letter:
once u had installed eclipse on D:\, after windows reinstall the drive-letter is now E:\ (for example).
look into eclipse.ini in your eclipse folder, there are some lines where the drive-letter is still D:\
This happened to me when I tried to open eclipse.exe before the .zip file finished extracting. Make sure all dependencies are unzipped or unpacked before opening the .exe.
I had this issue on Linux (CentOS 7 64 bit) with 32-bit Eclipse Neon and 32-bit JRE 8. Non of the answers here or in similar questions were helpful, so I thought it can help someone.
Equinox launcher (eclipse executable) is reading the plugins/ directory and then searches for eclipse_xxxx.so/dll in org.eclipse.equinox.launcher.<os>_<version>/. Typically, the problem is in eclipse.ini pointing to the wrong version of Equinox launcher plugin. But, if the file system uses 64-bit inodes, such as XFS and one of the files gets inode number above 4294967296, then the launcher fails reading the plugins/ directory and this error message pops up. Use ls -li <eclipse>/plugins/ to check the inode numbers.
In my case, moving to another mount with 32-bit inodes resolved the problem.
See: http://www.tcm.phy.cam.ac.uk/sw/inodes64.html
I encountered this error with the Eclipse 4.10 installer. We had failed to complete the install correctly due to platform security settings and attempted to uninstall but had to do it by hand since no uninstaller was introduced during the failed install. We suspected this corrupted the end result - even after re-installing.
The solution was to use the JVM to launch Eclipse and bypass the launcher executable entirely. The following command successfully launches Eclipse 4.10 (some parameters will change based on the version of Eclipse):
%JDK190%\bin\javaw.exe -jar C:\<fully_qualified_path_to_eclipse>\Eclipse410\plugins\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar -clean -showsplash
After using this command/shortcut to launch Eclipse we had no further errors with Eclipse itself but we weren't able to use the EXE launcher in the future. Even after a year of using this version, the launcher continues to display this same error.
To be clear, you'll have to modify your javaw.exe command to match your system specifications on MS Windows.
I got similar error sometime back. I had copied the eclipse setup from another laptop to mine. The issue with my setup was that path of the "--launcher.library" in the eclipse.ini file. The path in --launcher.library was that of the old machine and hence I was getting the error
I changed the path of "--launcher.library" in eclipse.ini to the path of eclipse on my laptop and the issue got resolved. I hope this is helpful to someone is getting this error.
remove it and run eclipse-installer again without root
I have create Demo.exe using Eclipse RCP.
I have run Demo.exe using C-Drive to same error generate like...
Solution : You might changed your drive for example
C:\Demo.exe to D:\Demo.exe
Step 1 : First Copy/Cut your .exe file like C:\Demo.exe
Step 2 : After Paste another drive like D:\Demo.exe
After executable file launching successfully.
I hope my answer is useful.
