I had to mask off CFLAGS_amd64 and CFLAGS_x86 because they cause the compile to fail as the target is not the same as the host. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 54732 [details] new ebuild that blocks CFLAGS_amd64 and CFLAGS_x86
according to the metadata.xml, this has not much to do with media-video@g.o: <herd>dev-embedded</herd> <maintainer> <email>dragonheart@gentoo.org</email> <name>Daniel Black</name> </maintainer> reassigning :)
this does bring up a good side point ... are the CFLAG abi variables going to screw everything up for cross-compiling ?
I was wondering the same thing. This one confused me greatly when I was trying to debug it. GCC kept failing saying the argument '64' was invalid. There was nothing on the command line that said anything about 64. I finally had the ebuild print out its enviromental variables and there were these two CFLAGS. When I cleared them everything worked. It was kind of disturbing that they didn't show up on the command line print out. They must be in the gcc wrapper somewhere. Scott =)
I think that if strip-unsupported-flags and strip-flags from flag-o-matic.eclass stripped CFLAGS_amd64 and CFLAGS_x86 also the extra cflags wouldn't hurt cross compiling nearly as much. Should I enter this as a separate bug? I have a new ebuild that should work if those two functions were updated. I can also check into updating them. Scott =)
no ... abi CFLAGS should not be breaking crap like this i'll chat with eradicator about it
Those two break every cross compile on my system. It is not just the AVR stuff. I am currently trying PPC. This is what I get trying to compile cross-i686-pc-linux-gnu/linux-headers: CRC-CCITT functions (CRC_CCITT) [N/m/y/?] (NEW) n CRC32 functions (CRC32) [Y/?] y CRC32c (Castagnoli, et al) Cyclic Redundancy-Check (LIBCRC32C) [M/n/y/?] m :0: sorry, unimplemented: 64-bit mode not compiled in :0: sorry, unimplemented: 64-bit mode not compiled in SPLIT include/linux/autoconf.h -> include/config/* CC scripts/mod/empty.o scripts/mod/empty.c:1: sorry, unimplemented: 64-bit mode not compiled in make[2]: *** [scripts/mod/empty.o] Error 1 make[1]: *** [scripts/mod] Error 2 make: *** [scripts] Error 2 !!!

If you need support, post the topmost build error, NOT this status message.
yes, eradicator and i discussed how the new amd64/2005.0/multilib stuff with CFLAGS_abi breaks cross-compiling pretty bad the workaround for now is to try `export ABI="EATME"` i think ...
crossdev exports a bogus ABI variable now since the stupid amd64 profile keeps forcing amd64 by default and no one is interested in fixing the situation any time soon
