Subject: [PATCH] Generate position independant code for static library
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit
Currently, only shared libraries are using the PIC flag.
Generalize this flag for static libraries in order to let them linkable
by dynamic libraries.
Fixes:
/home/gportay/src/buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-amd-linux-gnu/6.2.0/../../../../x86_64-amd-linux-gnu/bin/ld: /home/gportay/src/buildroot/output/host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libmemenv.a(memenv.o): relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC
/home/gportay/src/buildroot/output/host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libmemenv.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
Upstream-Status: Inappropriate [upstream has migrated to cmake]
