[Debichem-devel] Bug#837699: libmadness-dev: Please build libMAD*.a with -fPIC

[Balint Reczey]

Source: madness
Version: 0.10-8
Severity: important
User: balint at balintreczey.hu
Usertags: pie-bindnow-20160906
Justification: makes tiledarray FTBFS with extra hardening
Affects: tiledarray

Dear Maintainers,

During a rebuild of all packages in sid, tiledarray
failed to build on amd64 with patched GCC and dpkg. The root
cause seems to be that libMAD*.a are shipped as non-PIC libraries.

The rebuild tested if packages are ready for a transition
enabling PIE and bindnow for amd64 (and selected architectures).

For more information about the changes to sid's dpkg and GCC please

Relevant part of tiledarray's build log:
