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

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.
Thanks,
Robert
