Bug ID: 64296
Summary: link failure of libgccjit.so for "in tree"
gmp/mpc/mpfr/isl
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: jit
Assignee: dmalcolm at gcc dot gnu.org
Reporter: alfred.minarik.1 at aon dot at
using "in tree" gmp/mpc/mpfr/isl (as following contrib/download_prerequisites)
does not work with building jit.
gcc is correctly configured with --enable-host-shared but this information is
obviously not transferd into (or ignored by ?) gmp/mpc/mpfr/isl. Those static
libraries are still build without -fPIC,resulting in relocation failures while
linking libgccjit.so.
