Description Hanno Böck gentoo-dev

When I install lapack-reference it ends up installing a liblapack.so that links to a nonexisting libgfortran.so:

ldd /usr/lib/liblapack.so

	linux-vdso.so.1 (0x00007ffcd1bae000)
	libblas.so.3 => /usr/lib64/libblas.so.3 (0x00007f79866e5000)
	libgfortran.so.5 => /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/libgfortran.so.5 (0x00007f7986472000)
	libm.so.6 => /lib64/libm.so.6 (0x00007f7986335000)
	libgcc_s.so.1 => /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/libgcc_s.so.1 (0x00007f798631b000)
	libc.so.6 => /lib64/libc.so.6 (0x00007f798614c000)
	libgfortran.so.4 => not found
	libquadmath.so.0 => /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/libquadmath.so.0 (0x00007f7986108000)
	libz.so.1 => /lib64/libz.so.1 (0x00007f7985ef1000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f798703f000)

Please note it links against both libgfortran.so.4 and libgfortran.so.5, yet the first does not exist.

Comment 1 François Bissey 2019-04-26 08:25:24 UTC

I suspect libgfortran.so.4 comes from libblas which could have been linked to libgfortran.so.4 before you moved to gcc-8. `ldd -r` is good, but here to check what libraries liblapack is really linked against, I recommend to use
readelf -d /usr/lib/liblapack.so
