Bug 249359 – dev-libs/pslib: breaks with forced --as-needed

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Diego Elio Pettenò (RETIRED) 2008-11-30 11:24:42 UTC]

I'm reporting this bug because the package in summary breaks when forcing --as-needed on through spec files (check out http://blog.flameeyes.eu/2008/11/14/problems-and-mitigation-strategies-for-as-needed for details).

Please note that this bug _might_ apply to -Wl,--as-needed in LDFLAGS as well; in both cases it should be fixed. Also, if this is due to the package in question not respecting user-defined LDFLAGS, you should get to fix that too.

Check the attached build log.

Thanks,
Diego

Patch to add a check for pow in libm.so to configure.in

The root problem appears to be that libps.so calls pow(double, double), but does not link to libm.so.  This patch modifies configure.in to use AC_CHECK_LIB to check for pow in libm.so, and, if found, add -lm to the library line.

There is a stray assignment of -lm to an unused variable in one of the sub-Makefiles, but this configure change is preferred since it correctly handles systems where pow is part of libc.

Patch to pslib-0.4.1.ebuild to apply pslib-lm.patch and rebuild configure.in

Attachment #179282 [details, diff] is the first patch to an autotools file in this ebuild, so the ebuild will need to call eautoreconf to regenerate configure after the patch is applied.  This attachment modifies the ebuild to do so.
