Dear Dr. Cantwell, Yes, it is the same version of the library compiled with -fPIC version. Regards, Kamil 29.11.2014 23:48 tarihinde, Chris Cantwell yazdı:
Dear Kamil,
Can you confirm the library mentioned in the original error message (/truba/sw/centos6.4/lib/lapack/netlib-3.5.0-gcc/liblapack.a) is now the version of the library in your home directory in the latest error message?
Cheers, Chris

Dear Dr. Moxey,
I got in contact with the system administrator. 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?
Regards, Kamil

Hi Kamil,
The issue is related to linking. 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.
Thanks,
Dave

Dear All,
I'm trying to install Nektar++ 4.0 to a cluster with the options
NEKTAR_USE_BLAS_LAPACK ON NEKTAR_USE_SYSTEM_BLAS_LAPACK ON
with the path of the libraries as follows:
NATIVE_BLAS /truba/sw/centos6.4/lib/blas/netlib-gcc/blas_LINUX.a NATIVE_LAPACK /truba/sw/centos6.4/lib/lapack/netlib-3.5.0-gcc/liblapack.a
However, I'm getting the following error:
Linking CXX shared library libLibUtilities.so /usr/bin/ld: /truba/sw/centos6.4/lib/lapack/netlib-3.5.0-gcc/liblapack.a(dgbtrf.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC /truba/sw/centos6.4/lib/lapack/netlib-3.5.0-gcc/liblapack.a: could not read symbols: Bad value collect2: ld returned 1 exit status make[2]: *** [library/LibUtilities/libLibUtilities.so.4.0.0] Error 1 make[1]: *** [library/LibUtilities/CMakeFiles/LibUtilities.dir/all] Error 2 make: *** [all] Error 2
What may be the reason for this problem and how can I solve it?
Regards, Kamil
