Hi, Working on packaging OpenStack as part of my Hackweek 6 endeavor. Nova (one part of OpenStack) needs a newer version of redis than is available in OBS, thus I am sticking a copy into Virtualization:Cloud:OpenStack for now. I have run into a stupid link error that makes no sense to me, thus help is much appreciated. /usr/src/packages/BUILD/redis-2.0.4/redis.c:9293: undefined reference to `log' The math library is on the link line: cc -o redis-server -std=c99 -pedantic -O2 -Wall -W -fomit-frame-pointer -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -lm -pthread -fomit-frame-pointer -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -g -rdynamic -ggdb adlist.o ae.o anet.o dict.o redis.o sds.o zmalloc.o lzf_c.o lzf_d.o pqsort.o zipmap.o sha1.o This happens when building locally and in the build service. A log file can be found here: https://build.opensuse.org/package/live_build_log?arch=i586&package=redis&project=Virtualization%3ACloud%3AOpenStack&repository=openSUSE_11.3 The offending source line is: return (double)age*log(1+asize); don't see anything wrong wit that. This produces -> nm -Bg /var/tmp/build-root/usr/src/packages/BUILD/redis-2.0.4/redis.o | grep log U log in the object file and of course: -> nm -Bg /var/tmp/build-root//lib64/libm.so.6 | grep log 000000000001a520 T __clog10 0000000000027ca0 T __clog10f 0000000000030410 T __clog10l 0000000000019020 W clog 000000000001a520 W clog10 0000000000027ca0 W clog10f 0000000000030410 W clog10l 00000000000263c0 W clogf 000000000002eb50 W clogl 0000000000010670 W ilogb 000000000001fb20 W ilogbf 000000000002c140 W ilogbl 0000000000014230 W log 00000000000146c0 W log10 0000000000022fb0 W log10f 000000000002d5e0 W log10l 0000000000010720 W log1p 000000000001fb90 W log1pf 000000000002c170 W log1pl 000000000001aaa0 W log2 0000000000028100 W log2f 00000000000307b0 W log2l 0000000000010ad0 W logb 000000000001feb0 W logbf 000000000002c1b0 W logbl 0000000000022bf0 W logf 000000000002d530 W logl shows that log is defined in the math library. As a weak symbol, but never the less that should be good enough at link time. Help is much appreciated.
