Bug 244310 – dev-libs/glib-2.16.5: failed to emerge with CHOST and CFLAGS for an x86_64 architecture

• Status: RESOLVED INVALID
• Product: Gentoo Infrastructure

[Description Simone Eupili 2008-10-25 15:04:45 UTC]

The compilation fails with these settings in /etc/make.conf

CHOST="x86_64-pc-linux-gnu"
CFLAGS -march=athlon64

It works replacing with:

CHOST="i686-pc-linux-gnu"
CFLAGS -march=athlon



Reproducible: Always

Steps to Reproduce:
1. Set the make.conf for an amd64 architecture
2. emerge glib
3. Error!!

Actual Results:  
{standard input}: Assembler messages: 
{standard input}:72: Error: suffix or operands invalid for `cmpxchg' 
make[4]: *** [gatomic.lo] Error 1

Please include the complete build.log file, and also the output after running "emerge --info".  Thanks...  5:)

Please gather all information in this bug report, not on external sites.

[Comment 3 Jeroen Roovers (RETIRED) 2008-10-26 14:12:08 UTC]

Please read up on how to change CHOST[1], why you cannot turn an x86 OS into an amd64 OS just like that[2], and if you still want more, read up on how to do real cross compiling[3].
