Bug 385775 – dev-libs/apr-util does not cross compile

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Bertrand Jacquin 2011-10-05 19:49:16 UTC]

When you try to build apr-util while cross compiling, we should get the following error :


/bin/bash /usr/bin/libtool --silent --mode=compile x86_64-pc-linux-gnu-gcc -pthread  -Os -pipe -march=geode -mmmx -m3dnow -fomit-frame-pointer -DHAVE_CONFIG_H -D_REENTRANT -D_GNU_SOURCE   -I/var/tmp/i586-alix-linux-gnu/portage/dev-libs/apr-util-1.3.11/work/apr-util-1.3.11/include -I/var/tmp/i586-alix-linux-gnu/portage/dev-libs/apr-util-1.3.11/work/apr-util-1.3.11/include/private  -I/usr/include/apr-1    -o buckets/apr_buckets_flush.lo -c buckets/apr_buckets_flush.c && touch buckets/apr_buckets_flush.lo

buckets/apr_brigade.c:1:0: error: CPU you selected does not support x86-64 instruction set
make[1]: *** [buckets/apr_buckets_alloc.lo] Error 1

This is because BUILD compiler is used.

CC and CPP need to be export, as HOST LIBTOOL should be used

Reproducible: Always

Steps to Reproduce:
1. i586-alix-linux-gnu-emerge -va1 apr-util
2.
3.

ROOT variable shouldn't be used in src_*() phases. See PMS (12.1 Defined Variables).

this is wrong.  src_* should never use $ROOT.

[Comment 5 Nathan Phillip Brink (binki) (RETIRED) 2012-11-17 18:52:12 UTC]

Also, using the system-installed /usr/bin/libtool is wrong because that libtool contains hardcoded paths to gcc library directories which are generated at libtool’s installation time and not updated when the user installs or switches to new versions of gcc.

apr-util cross compile hacks

i got it to somewhat work with this.  adding external libs (like db) will still break though.  basically i point the configure script to the SYSROOT apr-config, then re-insert the SYSROOT prefix into the -I/-L paths.  it's terrible.

should be all set now in the tree; thanks for the report!
