aubio compiling fails : /lib/libm.so.6...

Hi i'm trying to compile latest aubio to test Ardour 3 on my new Slackware current machine

i get this

gcc -DAUBIO_PREFIX=\"/usr/local\" -I../src -I../ext -Wall -Wextra -I/usr/local/include -fPIC -o .libs/aubioonset aubioonset.o utils.o -L/usr/local/src/aubio-0.3.2/src -L/usr/local/src/aubio-0.3.2/ext /usr/local/src/aubio-0.3.2/ext/.libs/libaubioext.so /usr/local/src/aubio-0.3.2/src/.libs/libaubio.so -L/usr/lib/ /usr/lib/libjack.so -lrt -lpthread

thanks all

There's a SlackBuild for aubio-0.3.2, it's for 13.37, so I'm not sure if it would be OK for current. But you could try it.
http://slackbuilds.org/repository/13...braries/aubio/

I tried the slackbuild for 13.37 and i get the same error. I also tried reverting back 0.3.1 and i get the same thing. Googling around, people people are talking about linker issue and stuff i don't really understand.

Press the Report button and ask for this thread to be moved to the Slackware forum, possibly get more help there.

Did anyone ever get a solution to this problem. I'm in the same boat.

luckily gcc-4.7 is very eloquent

add a line

LDFLAGS="-lm" \

to the configure block of the slackbuild, like

LDFLAGS="-lm" \
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
./configure \

Thanks so much! That did the trick!
