Brendon, The gcc compiler is complaining that it no longer supports the /usr/include/malloc.h header being used in the third party BUFR library. You may be able to do a quick workaround by creating an empty malloc.h file that is used instead of the deprication malloc.h on your system with: touch /home/gempak/GEMPAK5.9.1/os/freebsd/include/malloc.h Then restart the build with: cd $NAWIPS make all install programs_nc programs_gf If your compiler refuses to let you override the malloc.h, then the instances of malloc.h in the C source routines will have to be blocked for stdlib.h conforming platforms as your /usr/include/malloc.h probably has upgraded the #warning starement for deprication to a #error type of directive.
