Bill, here's a good one for you.... I used the build-crossgcc.sh cript to build a ppc cross compiler on an i686 machine so I can build a linux-2.4.2 kernel for a board I'm working on. That process worked fine. Unfortunately when I try to build up util-linux-2.11 to create the mount utilities and friends, the compiliation complains that __NFDBITS and __FDMASK() are being redefined. It turns out that the <sys/select.h> in glibc-2.2.2 (misc/sys/select.h) doesn't check to see if they have been defined before, and in this case they were already defined because <linux/posix_type.h> defined them. Now the big question is who should define them???? Currently I've modified (in my local copies) <sys/select.h> to have an #ifndef around the duplicate definitions and so far it compiles. I haven't tried running it yet, but the types look like the same size. Any suggestions on how to properly fix this???? Here's the log from the build: powerpc-linux-gcc -c -O -pipe -O2 -fsigned-char -fomit-frame-pointer -Wa,-m403 -Ilib -Wall -Wmissing-prototypes -Wstrict-prototypes -I/usr/include/ncurses -DNCH=0 -D_FILE_OFFSET_BITS=64 -DSBINDIR=\"/sbin\" -DUSRSBINDIR=\"/usr/sbin\" -DLOGDIR=\"/var/log\" -DVARPATH=\"/var\" -DLOCALEDIR=\"/usr/share/locale\" -DHAVE_NFS -DMAIN lomount.c -o main_losetup.o In file included from /usr/local/wave/linux-cross-tools/host/i686-linux-gnu/lib/gcc-lib/ppc-linux-gnu/2.95.3/../../../../ppc-linux-gnu/sys-include/sys/types.h:209, from /usr/local/wave/linux-cross-tools/host/i686-linux-gnu/lib/gcc-lib/ppc-linux-gnu/2.95.3/../../../../ppc-linux-gnu/sys-include/bits/fcntl.h:25, from /usr/local/wave/linux-cross-tools/host/i686-linux-gnu/lib/gcc-lib/ppc-linux-gnu/2.95.3/../../../../ppc-linux-gnu/sys-include/fcntl.h:33, from lomount.c:20: /usr/local/wave/linux-cross-tools/host/i686-linux-gnu/lib/gcc-lib/ppc-linux-gnu/2.95.3/../../../../ppc-linux-gnu/sys-include/sys/select.h:52: warning: `__NFDBITS' redefined /usr/local/wave/linux-cross-tools/host/i686-linux-gnu/lib/gcc-lib/ppc-linux-gnu/2.95.3/../../../../ppc-linux-gnu/sys-include/linux/posix_types.h:22: warning: this is the location of the previous definition /usr/local/wave/linux-cross-tools/host/i686-linux-gnu/lib/gcc-lib/ppc-linux-gnu/2.95.3/../../../../ppc-linux-gnu/sys-include/sys/select.h:56: warning: `__FDMASK' redefined /usr/local/wave/linux-cross-tools/host/i686-linux-gnu/lib/gcc-lib/ppc-linux-gnu/2.95.3/../../../../ppc-linux-gnu/sys-include/linux/posix_types.h:34: warning: this is the location of the previous definition -- Peter Barada Peter.Barada@motorola.com Wizard 781-852-2768 (direct) WaveMark Solutions(wholly owned by Motorola) 781-270-0193 (fax) ------ Want more information?
