12.10. Threading Libraries

The threading library must be linked to the binaries using a special flag -pthread on FreeBSD. If a port insists on linking -lpthread directly, patch it to use -pthread.

Note:

If building the port errors out with unrecognized option '-pthread', it may be desirable to use cc as linker by setting CONFIGURE_ENV to LD=${CC}. The -pthread option is not supported by ld directly.
