I am new to Omnet++. I installed Omnetpp-3.3p1 and am having trouble opening it. I tried creating a makefile within the project which has simulation codes with command opp_makemake -f -N, but I am getting command opp_makemake not found error. Am I missing something here?
The error might raise if OMNeT++ is not properly installed or the lib is not properly linked. This PDF should be what you are looking for, since it explains how to properly install version 3.3p1. - Hope to help!

I have met a problem with hdf5 libraries on eclipse CDT. When running a test C++ program, I got prompt information as below:
/home/lsl/Documents/CODE/eclipse-workspace/ReadWriteHDF5/Debug/ReadWriteHDF5:
error while loading shared libraries: libhdf5.so.103: cannot open
shared object file: No such file or directory.
libhdf5.so is confirmed to exist in /usr/local/lib/hdf5-1.10.4/lib and /usr/local/lib/hdf5-1.10.4/lib is within LD_LIBRARY_PATH. Do you have any indications?
Thanks very much!
It looks like Linux is your main operating system. See what happens when you type
sudo apt install libhdf5-dev
since it might supplant the package you're looking for. It worked for me.
I come across similar issue while compiling C++ code that uses Armadillo. Since I have anaconda installed, I find the libhdf5.so.103 file located at ~/anaconda3/lib. After I add the path to LD_LIBRARY_PATH, the error disappears.
I came across exactly the same problem today (perhaps the only difference is that it complaint libhdf5.so.200 was missing). What I eventually found out is that the system (Ubuntu 20.04) already shipped with libhdf5-dev at version 1.10.4, and this conflicted somehow with my installed version 1.12.2. My build command line is as below:
clang++ <...> -L/my/custom/path/to/hdf5-1.12.2/hdf5/lib <...>
Since the system hdf5 is in standard location, the linker finds simultaneously two versions, causing problem.
My solution is:
sudo apt purge libhdf5-dev
Hope it helps.
After conscientiously following the install instructions on Linux from swift.org, I encounter an issue where it is not possible to compile anything on a Ubuntu 18.04 machine. The REPL seems to work but during compilation (when calling swift build) the following error appears:
/usr/bin/ld: cannot find -lstdc++
There are more details in the full bug report [SR-9093]. I don't know at all what to do to solve this issue, there are similar problems already mentioned in other bug reports, for instance on this really old one [SR-35].
What should I do?
Thank you
I am assuming that you had already installed the libstdc++ successfully and you have set the permissions properly. But I really doubt that it was installed correctly but it was installed with corruption of some sort. The corruption occurred because you didn't install libstdc++ via a package manager. Result was some form of weirdness in the package manager database which effected the overall functioning system. Exactly why adding something to a folder should change anything at all. I don't know why this happens, unless the folder is hot i.e symbolically linked to a program which doesn't have any tolerance for hacks like simply copying a file into the folder. So for now try to install the libstdc++ again. Below is the link to the file to again download the correct program and this is compatible with amd64.

Install libstdc++
sudo apt install libstdc++6
It seems possible that the apt install did not run the ldconfig program, which should be run to add the library to the list of those which ld.so knows about.
It looks like you can do it manually:
sudo ldconfig
IMPORTANT CAVEAT: I don't have Ubuntu and haven't been able to test this. And it's a sudo command. Run at your own risk, YMMV, etc.
If this does not work, it's possible that a file called /etc/ld.so.conf is not set up to search the directory where libstdc++ ended up. I wouldn't dare try to describe how to fix that.
sudo apt install -f
The command above should install any missing dependencies.
I am trying to install the MATLAB Runtime (see www.mathworks.com/products/compiler/mcr) on Cent0S 7. I think I have installed MCR correctly because the install finishes through saying it completed after running
sudo ./install -mode silent -agreeToLicense yes
However, I am currently getting a error of:
Fatal error loading library /usr/local/MATLAB/MATLAB_Compiler_Runtime/v80/bin/glnxa64/libmwmclmcr.so Error: libXmu.so.6: cannot open shared object file
I have searched around on the forums and found a couple of post that indicate this may be an issue with either 32-bit vs. 64-bit libraries and/or X Windows. Also, I am pretty sure I am setting the following environment LD_LIBRARY_PATH and XAPPLRESDIR set variables correctly.
Has anyone out there successfully installed MATLAB Runtime on CentOS 7? Any help would be appreciated.
Thanks,
Derek
In case anyone else has this issue the following library install fixed the issue for me:
sudo yum install libXmu.x86_64
I am trying to get work PostgresSQL with PHP, but i stuck on that apache error:
Call to undefined function pg_connect().
When i run phpinfo() i cannot see that my module is loaded, but i do not know why. The pgsql.ini files were loaded. And when i open them, i can see, that the extension is enabled extension=pgsql.so. Under /usr/lib64/php5/extensions there is the .so file. Even the permission are same like the other modules.
Any idea what am I doing wrong?
It would help if you could describe what operating system you are using. I'm assume Linux, but which distribution? One package that is often forgotten when installing postgresql and php is php5-pgsql. This is the connection between the two. For some reason I cannot explain, it is best if all three are installed together. So I suggest uninstalling postgresql and php and then installing postgresql, php5 and php5-pgsql. I hope this works for you!
I found it out. Some libraries where not found.
1.) First of all run php -version
2.) If there is an error where it described that some libraries are missing, you can solve it like me
3.) Search for the files on your system find / -name {LIBRARY NAME}
3a.) If you found them, just create a symlink to /usr/lib64
3b.) If not, find a way to get them and 3 3a
My final goal is to use Python scripts with SciPy, NumPy, Theano and openCV libraries to write code for a machine learning application. Everything worked so far apart from the openCV.
I am trying to install openCV 2.4.8 to use in Python projects in my Eclipse Kepler installation on my MBA running Mac OSX 10.9.2. I have the PyDef plugin v2.7 and a installation of Anaconda v1.9.1.
Here is what I did to install opencv:
sudo port selfupdate
sudo port upgrade outdated
sudo port install opencv
Then I realized that I can't use it that way in Python and did another:
sudo port install opencv +python27
Ok, then I had another Python installation and I added it to my PYTHONPATH in Eclipse>Preferences>PyDev>Interpreter-Python>Libraries.
Before the installation I got an error in the line import cv2, and everything else looked promising. Now this error disappeared but I get other errors when using any functions or variables of cv2. For example I get two errors in this line: cv2.cvtColor(image, cv2.COLOR_RGB2BGR)
Also Python crashes and has to be restarted when I run a simple test program which worked fine before.
With this PYTHONPATH everything works but I have no openCV:
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pyObjC
/Library/Python/2.7/site-packages/
/Users/xxx/anaconda/lib/python2.7/site-packages
When I add this new folder to the PYTHONPATH...
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
... openCV seems to work but I have the crashes and the other issue described above.
So, can anyone tell me what the problem is and what I can do to make this work?
Thanks for reading this so far and any help/hint you can provide! Please don't be too harsh, I am, as you can probably easily see just a beginner.
Ok, it's working now. Here is what I did:
Install Python and every package I need for it with Macports
Set the Macports version as standard
Adjust PATH and PYTHONPATH
Reboot (not sure if needed)
Remove old interpreter and libs in Eclipse
Choose the new Python installation as Interpreter in Eclipse
Confirm the new libs in Eclipse
Restart Eclipse
Done
