Bug 506254 – games-arcade/vor-0.5.5 - ld: rocks.o: undefined reference to symbol 'sqrtf@@GLIBC_2.0'

• Status: RESOLVED DUPLICATE of bug 505794
• Product: Gentoo Linux

[Description c.cboldt 2014-03-30 15:56:57 UTC]

Created attachment 373900 [details, diff]
Patch Makefile.in, adding "-lm" to $ldflags

Somewhat a carryover from the underlinking in vor-0.5.4, attached patch works, but is not necessarily the best way to construct the resulting Makefile.

Didn't mention, oops, that the vor-0.5.5.ebuild needs to be adjusted as well, to account for the patchfile.

Sorry about the duplicate.  I hit the "bugs" link on the ebuild field, and the page said Zarro Bugs found.  I'll search further next time!
