ports/math/gsl and ports/math/fftw don't use libtool from ports. It can cause problems with multithreaded programs that uses this libraries. Such program will be linked with both libc.so and libc_r.so. Fix: Using libtool from ports fixes the problem. I think port maintainers must correct this ports. How-To-Repeat: Just build this ports and check is dependencies: [/usr/ports/math/fftw]# ldd /usr/local/lib/libfftw.so libm.so.2 => /usr/lib/libm.so.2 (0x2812d000) libc.so.4 => /usr/lib/libc.so.4 (0x28069000)
Responsible Changed From-To: freebsd-ports-bugs->lkoeller Over to Maintainer of fftw port
State Changed From-To: open->closed Fix libtool usage and check that libc dependency of shared libs are avoided.
