Bug 357399 – sys-devel/gcc-4.5: Regression in library search paths on amd64-linux

• Status: RESOLVED FIXED
• Product: Gentoo/Alt

[Description Jeremy Olexa (darkside) (RETIRED) 2011-03-04 17:00:32 UTC]

Output via: 

% gcc --print-search-dirs|grep libraries | sed 's/:/\n/g'|sed 's/4.4.5/doesntmatter/g' > 4.4.5.txt

(and I mangled my EPREFIX for pretty output)

Please check on this as it will eventually cause problems (we debugged and issue on IRC)

do you have a symlink in your EPREFIX?

[Comment 2 Fabian Groffen 2011-03-05 15:16:10 UTC]

ohw, lib64 is your isssue, am I correct?

[Comment 3 Fabian Groffen 2011-03-05 15:18:38 UTC]

-       # try /usr/lib31 in 32bit profile on x86_64-linux (needs --enable-multilib),
-       # but this does make sense in prefix only.
-       use prefix && epatch "${FILESDIR}"/${PN}-4.4.1-linux-x86-on-amd64.patch
-

looks suspicious, patch was dropped

[Comment 4 Fabian Groffen 2011-03-05 15:24:52 UTC]

it's the prefix-search-dirs.patch patch's that's lacking, actually
