Dear all, =20 I met a problem when I compile DEAL.II (a general finite element library) in FreeBSD 4.10. After I run "gmake", I got the following information =20 " /usr/.../deal/deal.II/lib/libdeal_II_2d.g.so: undefined reference to 'pthread_mutex_unlock' /usr/.../deal/deal.II/lib/libdeal_II_2d.g.so: undefined reference to 'pthread_mutex_destroy' /usr/.../deal/deal.II/lib/libdeal_II_2d.g.so: undefined reference to 'pthread_mutex_lock' /usr/.../deal/deal.II/lib/libdeal_II_2d.g.so: undefined reference to 'pthread_mutex_init' =20 " Someone tell me to use=20 "export LIBS=3D-lpthread" before compile the library, but it didn't work. =20 And, It's said on FreeBSD, "gcc -pthread " will generate some problem http://lists.freebsd.org/mailman/htdig/freebsd-threads/2003-September/00 1203.html =20 =20 What can I do? =20 Best Regards, =20 Yandong=20
