I am trying to use Eclipse CDT under Ubuntu 18.04 LTS.
I get the same error as many others, but I could not find a solution in what I read.
I try to launch with
$ eclipse &
OpenJDK 64-Bit Server VM warning: Ignoring option MaxPermSize; support was removed in 8.0
and I get
/home/user1/.eclipse/org.eclipse.platform_3.8_155965261/configuration/1551271296090.log
When checking /usr/lib/eclipse/configuration/config.ini (as per this) I found the following lines (among others)
osgi.framework=file\:plugins/org.eclipse.osgi_3.8.1.dist.jar
osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.301.dist.jar#1\:start
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator/bundles.info
As for the first two lines, I have files
$ locate eclipse.osgi_
/usr/share/java/org.eclipse.osgi_3.8.1.dist.jar
$ locate simpleconfigurator_1
/usr/lib/eclipse/plugins/org.eclipse.equinox.simpleconfigurator_1.0.301.dist.jar
Nevertheless:
/usr/share/java/org.eclipse.osgi_3.8.1.dist.jar seems to belong to no package (a remnant of some old package?), since
$ apt-file search /usr/share/java/org.eclipse.osgi_3.8.1.dist.jar
gives no results.
I have ver 3.9.1
$ dpkg -l | grep libequinox-osgi-java
ii libequinox-osgi-java 3.9.1-1 all Equinox OSGi framework
$ dpkg -L libequinox-osgi-java

So I do not know if the problem is here.
How can I solve this?

You are probably using an older Eclipse version that does not work with Java 9 or higher:
If using Java 9 or newer please use Eclipse 4.7.1a or newer as it contains fixes in Eclipse launcher to add all JVM modules.
Do one of the following to solve the problem:
Use Java 8 to run Eclipse (a JRE/JDK can be put in the subfolder jre of your Eclipse installation or be specified in the eclipse.ini file)
Upgrade Eclipse (recommended).
I get the following when trying to build a makefile in eclipse neon:
Error: Program "make" not found in PATH
followed by my full path, which begins
Error: Program "make" not found in PATH PATH=[C:/Program
Files/Java/jre1.8.0_141/bin/server;C:/Program
Files/Java/jre1.8.0_141/bin;C:/Program
Files/Java/jre1.8.0_141/lib/amd64;C:\msys64\mingw64\bin;
(it continues after this...)
However, cmake is definitely present in C:\msys64\mingw64\bin.
How can I fix this so eclipse is using the cmake.exe?
Eclipse is looking for make program not cmake. To install make on MSYS2 use the command pacman -S make. CMake is a build system generator that creates Makefiles for you. But it does not build the Makefiles itself it uses an installed make for that.
Complete error message:
The JDK is missing and is required to run some NetBeans modules
Please use the --jdkhome command line option to specify a JDK installation or see http://wiki.netbeans.org/FaqRunningOnJre for more information.
Some details: I just installed Netbeans on Linux mint for the first time and when I start it when its turning on modules this error message appears. But I do have jdk installed.
$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
$ javac -version
javac 1.8.0_66
Find the file [netbeans installation directory]/etc/netbeans.conf
Luckily, Linux has a find helper like
find /home/ -name "netbeans.conf,
in which you can change the /home/ to a location where you want to search.
I found it at /usr/local/netbeans-8.1/etc/netbeans.conf
Once, you found the file, the following property needs to be set:
netbeans_jdkhome="[jdk_path]"
where you can find the jdk_path using:
update-alternatives --config java
In my case, I found it at /opt/java/jdk1.8.0_191
[Solved] For Mac OSX 10.11 (El Capitan).
Solution may be similar for other Unix-based systems.
The problem may have occurred because I inadvertently installed the jre
prior to installing the jdk. I uninstalled the jre, installed the jdk
and reinstalled NetBeans but the problem (popup window) remained.
However, the fix was fairly simple.
1. Make sure NetBeans is not running.
2. Make sure the jdk is installed.
3. Determine the location of the jdk:
The jdk location can be determined by entering the following (in Terminal):
$ /usr/libexec/java_home
For my system, the output was:
/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home
4. Edit the NetBeans configuration file to indicate the location of the jdk.
Near the bottom of this Netbeans configuration file (or equivalent for your NetBeans version):
/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf
Comment out the following line (insert a # before the first character):
#netbeans_jdkhome="/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/bin/jre"
Then, add the following line (or equivalent for your jdk version):
netbeans_jkdhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home"
Then, save and exit the editor.
5. Start NetBeans (no more popup window indicating that the jdk is missing).
When netbeans has problems trying to find the path of the jdk, it's mainly because the version of the jdk does not match. Open the file C:\Program Files\NetBeans 8.2\etc\netbeans.conf, and verify that netbeans_jdkhome = "C:\Program Files\Java\jdk1.8.0_111".
Open netbeans.conf
sudo nano "/usr/lib/jvm/java-8-oracle/netbeans.conf"
Set proper sdk path:
netbeans_jdkhome="/usr/lib/jvm/java-8-oracle"
Exit Ctrl + X and to save changes Ctrl + T
This error showed up when I updated the Mac to Mojave. To fix, I edited the netbeans.conf file with the current jdk by using Terminal to find the correct jdk. Type
/usr/libexec/java_home -V
Here was my output.
Matching Java Virtual Machines (4):
1.8.311.11 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
1.8.0_131 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
1.8.0_25 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home
1.7.0_79 (x86_64) "Oracle Corporation" - "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
Entering the first jdk listed did not work.
I edited the conf file with the second one listed:
netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home"
Restarted Netbeans. That fixed it.
This worked for me
1. install full JDK
2. either edit <netbeans-IDE-installation>/etc/netbeans.conf
2.1 unmark netbeans_jdkhome
2.2 link to JDK location e.g. /usr/local/share/java/jdk1.6.0_07/
3. or use --jdkhome command-line option e.g. ./bin/netbeans --jdkhome /usr/local/share/java/jdk1.6.0_07/
take care with the "/" at the end

Ubuntu 16.04 LTS:
Uninstall the netbeans you have.
Delete .cache/netbeans folder
Download http://www.oracle.com/technetwork/java/javase/downloads/jdk-netbeans-jsp-142931.html
Install your download
I have this problem to. But now i resolove this problem with edit one line.
Find and open this file /etc/netbeans.conf
If you see netbeans_jdkhome="C:\Program Files\Java\jre1.8.0_151" replace netbeans_jdkhome="C:\Program Files\Java\jdk1.8.0_131"
Save as adminstrator
Problem reseloved
In mid April 2019, Oracle has changed the JDK's licence. However, I was still able to solve this issue with NetBeans 11 and the JDK 12's open source build on my Windows machine. Just downloaded the open source JDK from https://jdk.java.net/ and extracted it. Then, in my NetBeans config file, I typed in the path to the extracted directory (NOT the "bin" folder!).
I resolved this problem by changing default version of JRE and JDK that I'm using to 11.x.x with following commands:
sudo update-alternatives --config java
sudo update-alternatives --config javac
I am working on Ubuntu 14.04 LTS and I would like to install eclipse 4.4. I did everything step by step with this site:
http://tutorialforlinux.com/2014/03/13/how-to-install-eclipse-4-3-kepler-standard-on-ubuntu-12-04-precise-lts-3264bit-linux-easy-visual-guide/
Now it is what I got after step 6 when I try to start eclipse:
zaba#zaba:~$ ls /opt/eclipse/
about_files configuration eclipse.ini icon.xpm
plugins about.html dropins
epl-v10.html notice.html readme artifacts.xml
eclipse features p2
zaba#zaba:~$ ls /usr/local/bin/
eclipse
zaba#zaba:~$ eclipse
bash: /usr/local/bin/eclipse: no such file or directory
zaba#zaba:~$
As you can see teoretically everything is on its place: 'eclipse' file in /opt/eclipse and its link in /usr/local/bin - I made it as in tutorial, by:
ln -s /opt/eclipse/eclipse /usr/local/bin/eclipse
But it does not work. Can anyone help, please?
since "A third-party application in /opt is supposed to be self-contained"
it should run through
/opt/eclipse/eclipse
if it does not, there is a problem either with your user or the executable, try just copying it to ~/bin
You might have a mismatch on 64-bit and 32-bit in your operating system and eclipse version.
I'm trying to generate an eclipse .project and .cproject from an existing cmake file. Running cmake from the project root I tried adding to the root CMakeLists.txt
set(CMAKE_ECLIPSE_VERSION=4.2) which apparently might do nothing as it is a local variable, not the global env variable, if i understand correctly.
Trying to add the flag to the commandline like this:
cmake -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_ECLIPSE_VERSION=4.2 .
Produces the following warning. So how does one let cmake know the eclipse version?
-- Could not determine Eclipse version, assuming at least 3.6 (Helios). Adjust CMAKE_ECLIPSE_VERSION if this is wrong.
I checked the .project file and it seems to be using cdt 4. Pretty old.

I had the same problem and after looking at CMake's code I noticed that the actual variable used to get the Eclipse's version is named _ECLIPSE_VERSION (starting with underscore) and not CMAKE_ECLIPSE_VERSION. Here's what the code looks like:
cmake -G"Eclipse CDT4 - Unix Makefiles" -D_ECLIPSE_VERSION=4.2 .
That worked for me!
EDIT: Older versions of CMake don't recognise Eclipse 4.2 (which uses CDT 8.1) but does recognize 3.7 (which uses CDT 8.0). I used -D_ECLIPSE_VERSION=3.7 and Juno picked up well the project configuration (previously I had unresolved inclusions due to incompatibility of the CDT4 files generated by default). As pointed out by m3tikn0b, newer versions of CMake do recognize until Eclipse Kepler 4.3.
There is a bug in CMake. See 0014422: CMAKE_ECLIPSE_VERSION is not taken into account. THe issue tracker says it will be corrected in cmake 2.8.13.
same problem here. After search i found the following solution:
previously tried:
cmake -G"Eclipse CDT4 - Unix Makefiles" -D_ECLIPSE_VERSION=4.2 ../src
and it doesn't work. Then i tried:
cmake -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_ECLIPSE_VERSION=4.2 ../src
This worked for me.. I hope it helps.
