Bug 464596 – net-libs/libdmapsharing-2.9.15 - Fails compilation at link stage - "-lm" missing in linked libs.

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description cmuelle8 2013-04-04 14:05:52 UTC]

The floorf function is used in the source of the pkg directly, at one place:

net-libs-libdmapsharing-2.9.15 # grep -r "floorf" *

work/libdmapsharing-2.9.15/libdmapsharing/dmap-connection.c:	dmap_hash_generate ((short) floorf (priv->dmap_version),


Trying to build the pkg yields
