Bug 83089 – emerge errors when compiling a perl module ebuild, it ignores the /etc/make.conf file while compiling and errors with "cc1: error: CPU you selected does not support x86-64 instruction set".

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Rick Jansen 2005-02-23 10:35:02 UTC]

This problem is a result of perl's ExtUtils::MakeMaker module. When it writes the Makefile from Makefile.PL, the OPTIMIZE variable is set to the default of '-O2 -march=athlon-xp'. Which causes errors on perl modules written partially in C.

Reproducible: Always
Steps to Reproduce:
emerge perl-tk or emerge MIME-Base64

Actual Results:  
It tries to compile with -march=athlon-xp.

Expected Results:  
It should compile with CFLAGS from make.conf.

I see perl-tk and MIME-Base64 erroring out. I came across this problem because
emerge world tried MIME-Base64. I'm emerging world from a rather outdated
(2004.0) system.

Can you paste perl -V output? The optimize should be getting set to whatever you build perl under.

[Comment 2 Michael Cummings (RETIRED) 2005-05-16 09:19:28 UTC]

closing due to a lack of follow up. problem was indicative of changing compile flags at some point following the installation of perl.
