Dear petsc-users, I am trying to install petsc with the option --with-precision=__float128. The ./configure goes fine, as well as the make all stage. However, the make check step to test the libraries fails with the following error:
/usr/bin/ld: home/spin/petsc-3.9.3/arch-linux2-c-opt/lib/libpetsc.so: undefined reference to `dgemv_' this is the configure command I use: ./configure --with-scalar-type=complex --with-precision=__float128 --with-debugging=0 --with-fortran-kernels=1 COPTFLAGS='-O3 -march=native -mtune=native' CXXOPTFLAGS='-O3 -march=native -mtune=native' FOPTFLAGS='-O3 -march=native -mtune=native' --download-f2cblaslapack Any hints or suggestions are welcome. Thanks so much in advance! Santiago
