i was trying to compile Lapack 3.5.0 (also 3.4.2) with shared libraries support (-fPIC):
download tar
- Code: Select all
untar
cd lapack-3.5.0
mkdir build_linux
cd build_linux/
cmake ../
cp ../INSTALL/make.inc.gfortran make.inc
vim make.inc # I have added -fPIC option in OPTS and NOOPT
- Code: Select all
make
make test
and tried
- Code: Select all
readelf --relocs TESTING/EIG/CMakeFiles/xeigtstz.dir/alareq.f.o | egrep '(GOT|PLT|JU?MP_SLOT)'
I got empty output (the file was not compiled with -fPIC)!!!
When I add -fPIC in CMakeCache.txt (CMAKE_Fortran_FLAGS:STRING='-fPIC -m64 -frecursive'), everything was correct:
- Code: Select all
readelf --relocs TESTING/EIG/CMakeFiles/xeigtstz.dir/alareq.f.o | egrep '(GOT|PLT|JU?MP_SLOT)'

Question: is it bug that editing make.inc doesn't work even it is described as a proper way to set options? Or, am I missing something?
thanks, Tomas
