Source: liblpsolve55-dev Version: 5.5.0.15-4 Severity: important User: [email protected] Usertags: pie-bindnow-20160906 Justification: makes mccs FTBFS with extra hardening Affects: mccs libreoffice
Dear Maintainers, During a rebuild of all packages in sid, mccs failed to build on amd64 with patched GCC and dpkg. The root cause seems to be that liblpsolve55.a is shipped as a non-PIC library. 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 visit: https://wiki.debian.org/Hardening/PIEByDefaultTransition Relevant part of mccs's build log: ... g++ -Wall -O6 -Wl,-z,relro -Wl,-z,now -DUSELPSOLVE -o mccs objs/cudf.o objs/constraint_generation.o objs/lp_solver.o objs/pblib_solver.o objs/removed_criteria.o objs/changed_criteria.o objs/new_criteria.o objs/notuptodate_criteria.o objs/nunsat_criteria.o objs/count_criteria.o objs/unaligned_criteria.o objs/lexicographic_combiner.o objs/lexagregate_combiner.o objs/agregate_combiner.o objs/lexsemiagregate_combiner.o objs/leximin_combiner.o objs/leximax_combiner.o objs/lexleximin_combiner.o objs/lexleximax_combiner.o objs/cudf_reductions.o objs/lpsolve_solver.o -lfl -L. -lccudf \ \ \ -L/usr/lib -llpsolve55 -ldl -lcolamd \ /usr/bin/ld: /usr/lib/liblpsolve55.a(lp_lib.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC ...
