Bug 149565 – sys-devel/gcc-3.4.6-r2 native build crossdev

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Daniel Glaser 2006-09-29 14:33:20 UTC]

After building the toolchain, emerging gcc natively for the target-system, so it can be used later on the system itself, it encounters errors, that can be avoided by filtering out cpu specific CFLAGS (in my case -mtune and -mcpu).

If not filtering out, configure stops.

Reopen with some errors, a lot more useful that describing it... :)

[Comment 2 Daniel Glaser 2006-09-30 00:39:15 UTC]

Here is my make.conf
#If this line is used, getting errors
CFLAGS="-Os -mcpu=405 -mtune=405 -fomit-frame-pointer -pipe"
#If this, compiles cleanly
#CFLAGS="-Os -fomit-frame-pointer -pipe"
CXXFLAGS="${CFLAGS}"

I think, it is because of different stages that are compiled. First some things for the BUILD, then for the HOST. For the BUILD-stage, there must be some flags filtered out. For now, I'm happy without -mtune and -mcpu, because of the possibility to recompile gcc on the target with flags.

Could you attach the config.log it references in the error (if you are still even having this problem)?

(In reply to comment #3)
Sorry, takes to mauch time to set this up again for the moment... Perhaps I can do it in 1 or 2 weeks...
