Instalation error #11

Hi, I have some problems when installing HERMES. When I do the "CMAKE_PREFIX_PATH=$HERMES_DIR cmake -DCMAKE_INSTALL_PREFIX=$HERMES_DIR -DENABLE_TESTING=On .." I get a warning:

CMake Warning at lib/gtest/googletest/CMakeLists.txt:47 (project): VERSION keyword not followed by a value or was followed by a value that expanded to nothing.

But it still works. Then, when I do the "make -j" I get an error:

/usr/bin/ld: /usr/local/lib/libfftw3f.a(assert.o): relocation R_X86_64_PC32 against symbol `stdout@@GLIBC_2.2.5' can not be used when making a shared object; recompile con -fPIC /usr/bin/ld: final link failed: bad value collect2: error: ld returned 1 exit status make[2]: [CMakeFiles/hermes.dir/build.make:886: libhermes.so] Error 1 make[1]: [CMakeFiles/Makefile2:646: CMakeFiles/hermes.dir/all] Error 2

What could I do? I am in Ubuntu 20.04

Thank you in advance.

Thanks for informing us about the warning. We will fix it in the next release.

Hi! Try to link it with the dynamic FFTW3 library (ending with .so), not static (ending with .a). For example: -DFFTW3F_LIBRARIES=/path/to/library/../libfftw3f.so. It looks like you have a locally-built FFTW (without -fPIC) - you should use the one from the repository.

Which compiler version are you using for C++?

I don't think it is an issue from our side. CMake found a locally-built FFTW (inside of /usr/local/) which is obviously compiled incorrectly for the linkage with other sources (without -fPIC). Hence, the user should either use: an official repository version of FFTW (recommended, and well tested), or recompile a local FFTW with the -fPIC option present.

I had downloaded the package from http://www.fftw.org/ and compiled it following their guide. I have just recompiled it with --enable-shared=yes and it works correctly now. Thank you very much!!
