Bug 276797 – dev-libs/libevent-1.4.11 fails to build with --as-needed --no-undefined

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Kevin Pyle 2009-07-06 17:06:40 UTC]

With LDFLAGS="-Wl,--as-needed,--no-undefined", libevent-1.4.11 fails to link libevent_extra.so because it uses symbols from libevent.so, but does not explicitly link to libevent.so.  Adding libevent.la to the LIBADD for libevent_extra allows libevent to compile successfully.

Patch to modify ebuild to extend sed expression to fix linking of libevent_extra.so

Could you additionally explain why your patch uses eautoreconf instead of elibtoolize?

[Comment 3 Kevin Pyle 2009-07-07 01:56:09 UTC]

The sed expression changes Makefile.am, so Makefile.in needs to be rebuilt.  It might be sufficient to use elibtoolize+eautomake, rather than letting eautoreconf do both.

Thank you.

It's in the tree, in -r1. I'll send it upstream as well.

Never mind that - there isn't anything to send. :)
