From: Thomas Claveirole Date: Fri, 29 May 2015 16:15:10 +0000 (+0200) Subject: libfcgi: link with libm when needed X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=51c9ee06553a533e1404ee512c998b15f4b73fa2;p=buildroot.git libfcgi: link with libm when needed libfcgi uses frexp() and thus should link with libm, but fails to do so. Thus link errors with programs that use libfcgi (the bug does appear only with uClibc, because the GNU libc provides frexp() directly in libc.so). Modify 0003-link-against-math.patch so libfcgi links against math, instead of programs that need it.
