While compiling boost-libs with gcc7 (on NetBSD/amd64 8.1, in a pkg_comp1 chroot), I had a bunch of errors like libs/math/build/../src/tr1/hermitel.cpp:1:0: fatal error: had to relocate PCH for different files. Googling this error only gave few hits, suggesting "precompiled headers" and something with memory management. Going by "relocate" I guessed that maybe ASLR might be in play here, so I globally disabled it. Then building worked. Also with paxctl +a /scratch/chroot/pkg_comp.amd64-8.1/default/usr/pkg/gcc7/libexec/gcc/x86_64--netbsd/7.4.0/cc1* building succeeded. So I guess at this point that gcc's precompiled headers contain pointers and are not compatible with ASLR. So which of the two features do we want to disable for gcc 7? Or is there another option? (Other versions of gcc may be affected too, but I did not check). -Olaf. -- Olaf 'Rhialto' Seibert -- rhialto at falu dot nl ___ Anyone who is capable of getting themselves made President should on \X/ no account be allowed to do the job. --Douglas Adams, "THGTTG"
