Re: Please help building bwa on freebsd [noreply@buildd.debian.org: failed kfreebsd-amd64 build of bwa 0.7.12-1]

The solution may simply be to link with -lrt.

    $ cat shmopen.c
    #include <sys/mman.h>
    #include <stdio.h>
    int main() { printf("%p\n", shm_open); return 0; }
    $ gcc shmopen.c
    /tmp/ccRPQFME.o: In function `main':
    shmopen.c:(.text+0x5): undefined reference to `shm_open'
    collect2: error: ld returned 1 exit status
    $ gcc shmopen.c -lrt && ./a.out
    0x400540
    $ lsb_release  -d
