Hi,

1. I have tried today

crossdev --target powerpc-unknown-linux-gnu

and got the error message:

configure:2114: checking for powerpc-unknown-linux-gnu-gcc
configure:2141: result: x86_64-pc-linux-gnu-gcc

checking whether x86_64-pc-linux-gnu-gcc  -pipe -freorder-blocks -O2
-fno-strict-aliasing supports -mabi=ibmlongdouble... no
configure: error: this configuration requires -mlong-double-128 IBM
extended format support
 * ERROR: cross-powerpc-unknown-linux-gnu/glibc-2.13-r2 failed (compile
phase):
 *   failed to configure glibc

2. After looking at
/tmp/portage/cross-powerpc-unknown-linux-gnu/glibc-2.13-r2/work/glibc-2.13/configure

I found out that the environment variable CC is wrong.

This command worked:

crossdev --lenv "CC=powerpc-unknown-linux-gnu-gcc" --target
powerpc-unknown-linux-gnu

3. Is this a correct behavior that I need to set CC on the commandline?

4. I have a question about the loading of /usr/share/config.site
in glibc-2.13/configure

crossdev --lenv "CC=powerpc-unknown-linux-gnu-gcc" --target
powerpc-unknown-linux-gnu


>>> Compiling source in
/tmp/portage/cross-powerpc-unknown-linux-gnu/glibc-2.13-r2/work/glibc-2.13
...

 *             ABI:   default
 *          CBUILD:   x86_64-pc-linux-gnu
 *           CHOST:   x86_64-pc-linux-gnu
 *         CTARGET:   powerpc-unknown-linux-gnu
 *      CBUILD_OPT:
 *     CTARGET_OPT:
 *              CC:   powerpc-unknown-linux-gnu-gcc
 *          CFLAGS:   -pipe -freorder-blocks -O2 -fno-strict-aliasing
 *       Manual CC:   powerpc-unknown-linux-gnu-gcc


configure: loading site script /usr/share/config.site

When the script /usr/share/config.site is executed, the above value
CHOST=x86_64-pc-linux-gnu
is used to find the site script files in /usr/share/crossdev/include/site.

Is this correct?
Is it looking for the definitions of the build system or the target system?

I am using sys-devel/crossdev-20110310

Best regards

Jan

you didnt say what step this was exactly.  is it the glibc headers step or is 
it glibc itself ?

if it's the actual libc build (not the headers), it should work now

Hi Mike,

the step has been
 * Emerging cross-glibc ...

The new version of glibc can be built now without problems.

Thank your for fixing it this fast.
