Bug 16116 – mpg123 distcc cross compile failed

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tom Ward 2003-02-20 21:11:49 UTC]

When I try to emerge mpg123 the compile fails. I am using portage with distcc on ppc, 
and a distcc server on athlon, with a cross compiler. The athlon requires a fully 
qualified gcc, to ensure it uses the cross compiler rather than the native compiler. The 
mpg123 makefile contains an explicit reference to "gcc", so the distcc server invokes 
the wrong compiler, causing the error. This will affect all platforms using distcc with 
multiple architectures. A simple fix is to adjust the mpg123-0.59r-r1 ebuild with: 
 
26,28d25 
< #             ensure compilation on cross platform distc configs... 
< #             ...and borks the Makefile in the process 
<               -e "s:gcc:${CHOST}-gcc:" \ 
 
But this makes a real mess of mpg123's Makefile. A better solution would modify only 
the necessary part of the Makefile. 

Reproducible: Always
Steps to Reproduce:
1. Attempt to emerge mpg123 with distcc enabled and a cross compiling distcc server 
2. File bug 
3. 
Actual Results:  
Compilation fails, due to incorrect binary format. 

Expected Results:  
Compiled.

Removes CC=gcc from the Makefile.

This patch removes the CC=gcc references from the Makefile. Any line that has
CC=cc or some other compiler is not touched by this patch.

ebuild

This ebuild applies the Makefile patch.

This is what I have done on my machines. 
With this patch applied CC can be specified on the command line. 
 
CC=i686-pc-linux-gnu-gcc emerge mpg123 
 
This will now allow use the full name for the local compiler so the remote distccd uses 
the correct compiler.

This patch has been added to portage as -r2.  It looks great.
