In PETSc-3.16.0, the linker is not working because of these undefined references (see https://pastebin.com/izGTfmMp): /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `operator delete(void*, unsigned long)' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `__cxa_rethrow' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `__gxx_personality_v0' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `operator new(unsigned long)' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `std::__throw_bad_alloc()' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `std::terminate()' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `std::__throw_bad_array_new_length()' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `typeinfo for std::exception' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `__cxa_begin_catch' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `__cxa_end_catch' /usr/bin/ld: x86_64/lib/libpetsc.so: undefined reference to `std::__throw_length_error(char const*)' collect2: error: ld returned 1 exit status There are also $ ldd -r build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so' Start: shell linux-vdso.so.1 (0x00007fffbf347000) libsuperlu.so.5.2 => /lib64/libsuperlu.so.5.2 (0x00007f00dad0c000) libflexiblas.so.3 => /lib64/libflexiblas.so.3 (0x00007f00da95a000) libcgns.so.4.2 => /lib64/libcgns.so.4.2 (0x00007f00da873000) libhdf5.so.103 => /lib64/libhdf5.so.103 (0x00007f00da4d8000) libm.so.6 => /lib64/libm.so.6 (0x00007f00da3f8000) libX11.so.6 => /lib64/libX11.so.6 (0x00007f00da2ae000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f00da294000) libc.so.6 => /lib64/libc.so.6 (0x00007f00da08b000) libgfortran.so.5 => /lib64/libgfortran.so.5 (0x00007f00d9dde000) libquadmath.so.0 => /lib64/libquadmath.so.0 (0x00007f00d9d94000) /lib64/ld-linux-x86-64.so.2 (0x00007f00dc18b000) libsz.so.2 => /lib64/libsz.so.2 (0x00007f00d9d8a000) libz.so.1 => /lib64/libz.so.1 (0x00007f00d9d6e000) libxcb.so.1 => /lib64/libxcb.so.1 (0x00007f00d9d43000) libXau.so.6 => /lib64/libXau.so.6 (0x00007f00d9d3d000) undefined symbol: _ZTISt9exception (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: __gxx_personality_v0 (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: _ZdlPvm (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: __cxa_rethrow (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: _Znwm (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: _ZSt17__throw_bad_allocv (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: _ZSt9terminatev (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: _ZSt28__throw_bad_array_new_lengthv (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: __cxa_begin_catch (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: __cxa_end_catch (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) undefined symbol: _ZSt20__throw_length_errorPKc (build/BUILD/petsc-3.16.0/petsc-3.16.0/x86_64/lib/libpetsc.so) I'm attaching configure.log and make.log -- --- Antonio Trande Fedora Project mailto: [email protected] GPG key: 0x29FBC85D7A51CC2F GPG key server: https://keyserver1.pgp.com/
