Description Bertrand Jacquin 2008-06-12 08:12:56 UTC

iproute2 use host gcc in place of toolchain gcc so crosscompilation failed. Host gcc is used only in directory netem as you can see in this trace :

This bug is a revival of #54943


Reproducible: Always

Steps to Reproduce:
1. ROOT=/root/cross/i586-geode-linux-uclibc
PORTAGE_CONFIGROOT=/etc/ct/i586-geode-linux-uclibc
CHOST=i586-geode-linux-uclibc CBUILD=x86_64-pc-linux-gnu emerge -vat iproute2

that is because host gcc is *supposed* to be used in the netem subdirectory.  it's building utilities that it then executes.

the problem is that the target CFLAGS bleed and get used when executing on the build system.

Comment 2 Bertrand Jacquin 2008-06-12 17:31:16 UTC

Yes, I corrected the "bug" by doing that :

Then build like that :

CHOST=i586-geode-linux-uclibc CBUILD=x86_64-pc-linux-gnu CBUILD_CFLAGS="-march=athlon64 -O2 -pipe -fomit-frame-pointer" emerge -vat iproute2

It's really bad and just home working, so didn't post any fix.

But, what could be done for that ? Desactivate SUBDIR for cross compilation ? Get upstream ?
