Including Matlab into Qt: Runtime Error - Shared object not open
-
I'm trying to include a Matlab program into Qt Creator on Ubuntu by using the Matlab Compiler. Therefore, I use a simple test program. In terminal everything works fine when I export LD_LIBRARY_PATH like this:
export LD_LIBRARY_PATH=/home/robin/Matlab_Runtime/v93/runtime/glnxa64:/home/robin/Matlab_Runtime/v93/bin/glnxa64:/home/robin/Matlab_Runtime/v93/sys/os/glnxa64:
and then run the program. Building the project in Qt Creator works fine, too, but on runtime I'm getting:
An Error has occurred while trying to initialize the MATLAB Runtime. The error is: Fatal error loading library /home/robin/Matlab_Runtime/v93/bin/glnxa64/libmat.so Error: /home/robin/Matlab_Runtime/v93/bin/glnxa64/libmat.so: shared object not open An Error has occurred while trying to initialize the MATLAB Runtime. The error is: Fatal error loading library /home/robin/Matlab_Runtime/v93/bin/glnxa64/libmwmclbase.so Error: /home/robin/Matlab_Runtime/v93/bin/glnxa64/libmwmclbase.so: shared object not open could not initialize the application properly
My LD_LIBRARY_PATH is:
/home/robin/Qt/5.9.1/gcc_64/lib:/home/robin/projects_opencv/Matlab_compiler_test/../../Matlab_Runtime/v93/runtime/glnxa64/:/home/robin/Matlab_Runtime/v93/runtime/glnxa64:/home/robin/Matlab_Runtime/v93/bin/glnxa64:/home/robin/Matlab_Runtime/v93/sys/os/glnxa64:/home/robin/Matlab_Runtime/v93/sys/opengl/lib/glnxa64:/home/robin/Matlab_Runtime/v93/extern/include
Relevant lines in my .pro file:
INCLUDEPATH += /home/robin/Matlab_Runtime/v93/extern/include LIBS += -L$$PWD/../../Matlab_Runtime/v93/runtime/glnxa64/ -lmwmclmcrrt INCLUDEPATH += $$PWD/../../Matlab_Runtime/v93/runtime/glnxa64 DEPENDPATH += $$PWD/../../Matlab_Runtime/v93/runtime/glnxa64 LIBS += -L$$PWD/../../Matlab_Runtime/v93/bin/glnxa64/ -lmat -lmwmclbase INCLUDEPATH += $$PWD/../../Matlab_Runtime/v93/bin/glnxa64 DEPENDPATH += $$PWD/../../Matlab_Runtime/v93/bin/glnxa64
I'm grateful for any kind of help on this. Thank you very much!

@Rob123 Are you trying to start your app from QtCreator?
If so then set the LD_LIBRARY_PATH variable in Run settings of your project (in QtCreator on the left side "Projects/Build & Run".@jsulm Thank you for your answer! I did already. My LD_LIBRARY_PATH in build and run in environment is both: /home/robin/Qt/5.9.1/gcc_64/lib:/home/robin/Matlab_Runtime/v93/runtime/glnxa64:/home/robin/Matlab_Runtime/v93/bin/glnxa64:/home/robin/Matlab_Runtime/v93/sys/os/glnxa64:/home/robin/Matlab_Runtime/v93/sys/opengl/lib/glnxa64:/home/robin/Matlab_Runtime/v93/extern/include

Hi,
Not to nitpick, but you’re missing the LD_ in the environment variable name. Is it a typo here ?

Did you try to run ldd on these libraries to check their dependencies ?

@Rob123 Did you solve this problem? I am encountering the same issue. Could you please tell me how to resolve this if you have found a way?
