Dear all, When I’m trying to compile branch “MovingBodies” of nektar++ on cx2, I got some errors as follows: CMakeFiles/ExtractMeanModeFromHomo1DFld.dir/ExtractMeanModeFromHomo1DFld.cpp.o: file not recognized: File truncated make[2]: *** [utilities/PostProcessing/ExtractMeanModeFromHomo1DFld-3.4.0] Error 1 make[1]: *** [utilities/PostProcessing/CMakeFiles/ExtractMeanModeFromHomo1DFld.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs…. However, the compiling process of the “master” branch is very smoothly on cx2, and I did not get any such errors when compiling my branch on victoria/euston nodes. How can I fix it? many thanks.

He told that it is impossible to recompile blas and lapack on the system with -fPIC option. Alternatively, he copied the Blas and Lapack libraries from the directory in the system to another folder in my home directory and recompiled them there with -fPIC option. However, when I tried to reinstall Nektar by showing the path of new Blas and Lapack libraries in my home directory I got the same error. Is there any other alternative way to overcome this problem?

We generate shared libraries in Nektar++, but here we are trying to link the shared library with a static library. You can only do this if the static library was compiled with the -fPIC option, which generates position-independent code that shared libraries need in order to work at runtime. If you have a shared library, you should use this. Otherwise, you should recompile BLAS/Lapack installation with the -fPIC option. This may be something that your cluster system administrators can help with.
