Run an application in Qt4.6 Linux

[Wu]

Hi, all,

I can build an application both in terminal and Qt4.6, but it can only run in terminal. When I tried to run it in Qt4.6, I got this error message:" error while loading shared libraries: libcudart.so.2: cannot open shared object file: No such file or directory". I think it might be a library dependencies problem. The following is my .pro file

Please help me out. Thank you very much.

make sure libcudart.so.2 is located in the paths specified under LD_LIBRARY_PATH

[Wu]

Hi,

Thank you for your reply. My LD_LIBRARY_PATH variable for build and run environment is /home/wu/qtsdk-2009.05/lib/qtcreator. I moved libcudart.so.2 file to /home/wu/qtsdk-2009.05/lib/qtcreator directory and tried to run again, but I still got the same error message.

Best,
Wu

[high_flyer]

well, libcudart.so.2 is found.
What happens if you launch creator from the console and then try to run the application from creator?

[Wu]

I got the following message:

Starting /home/wu/Desktop/E47/FOLKI_GPU/bin/FolkiGpu...
/home/wu/Desktop/E47/FOLKI_GPU/bin/FolkiGpu: error while loading shared libraries: libcudart.so.2: cannot open shared object file: No such file or directory
/home/wu/Desktop/E47/FOLKI_GPU/bin/FolkiGpu exited with code 127

[high_flyer]

Just add libcudart.so.2's location to your LD_LIBRARY_PATH.
I am quite sure it will fix the problem.

[squidge]

I moved libcudart.so.2 file to /home/wu/qtsdk-2009.05/lib/qtcreator directory and tried to run again, but I still got the same error message.libcudart.so.2 is probably just a soft-link to another file in the same directory (or depends on other files in that directory). Instead of copying the file elsewhere, include the path to that file in your LD_LIBRARY_PATH, as already suggested.

[Wu]

I added the directory (/usr/local/cuda/lib64/) containing libcudart.so.2 to LD_LIBRARY_PATH variable in the Build and Run Environment of the Projects settings. The application still can not run in Qt. How can I add a directory to LD_LIBRARY_PATH in Qt? Thank you very much.

Best,
Wu

[Wu]

It works now. Thank you very much.

Wu
