Hi, Marius Bakke <marius@gnu.org> skribis: > Arguably running code for foreign architectures through QEMU binfmt is > something of a hack.

I’m fine with dropping things on the build farm; it’s just about modifying machines-for-berlin.scm in maintenance.git. Any takers? :-) > A less user-hostile solution could perhaps be to (setenv "CFLAGS" > "-D_FILE_OFFSET_BITS=64") on 32-bit architectures in gnu-build-system. > Not sure whether that could cause any adverse effects. But again, I > don't like the idea of optimizing for QEMUs user-mode emulation. The above would override the default CFLAGS in Autoconf-generated configure scripts (which is “-O2 -g”). So we’d have to be cautious. But I think a global solution is preferable to adding -D_FILE_OFFSET_BITS=64 to tens of packages. WDYT? Ludo’.
