Building OpenFirmware svn rev 795
by Robert Davidson 26 Sep '08

26 Sep '08

Hi all, I'm hoping someone can tell me whats wrong or why I can't build OpenFirmware rev 795. I'm trying to follow the instructions at http://www.openfirmware.info/Open_Firmware#Build_Open_Firmware but they're not working. I keep getting errors when running 'make'. I have tried modifying the configuration as the above site suggests, and I've also tried without making any changes at all, both fail with the same error at the same place. My primary goal right now is to simply play with coreboot and OpenFirmware in qemu, then I might consider trying it on some real hardware. Any help is appreciated. make[1]: Entering directory `/usr/src/coreboot/build-qemu/openfirmware/cpu/x86/Linux' cc -c -O -g -m32 -DTARGET_X86 ../../../forth/wrapper/wrapper.c -o wrapper.o cc -c -O -g -m32 -DTARGET_X86 ../../../forth/wrapper/logger.c -o logger.o cc -c -O -g -m32 -DTARGET_X86 -I../../../forth/wrapper/zip ../../../forth/wrapper/zip/zipmem.c -o zipmem.o cc -c -O -g -m32 -DTARGET_X86 -I../../../forth/wrapper/zip ../../../forth/wrapper/zip/deflate.c -o deflate.o cc -c -O -g -m32 -DTARGET_X86 -I../../../forth/wrapper/zip ../../../forth/wrapper/zip/trees.c -o trees.o cc -c -O -g -m32 -DTARGET_X86 -I../../../forth/wrapper/zip ../../../forth/wrapper/zip/bits.c -o bits.o cc -c -O -g -m32 -DTARGET_X86 -I../../../forth/wrapper/zip ../../../forth/wrapper/zip/util.c -o util.o cc -c -m32 -O0 -fpic ../../../forth/wrapper/zip/inflate.c -o inflate.o cc -m32 -o forth wrapper.o logger.o zipmem.o deflate.o trees.o bits.o util.o inflate.o make[1]: Leaving directory `/usr/src/coreboot/build-qemu/openfirmware/cpu/x86/Linux' make[1]: Entering directory `/usr/src/coreboot/build-qemu/openfirmware/cpu/x86/build' make -C ../Linux ../build/inflate.bin make[2]: Entering directory `/usr/src/coreboot/build-qemu/openfirmware/cpu/x86/Linux' objcopy -O binary inflate.o ../build/inflate.bin make[2]: Leaving directory `/usr/src/coreboot/build-qemu/openfirmware/cpu/x86/Linux' make[1]: Leaving directory `/usr/src/coreboot/build-qemu/openfirmware/cpu/x86/build' ./build ofw.c32 --- Rebuilding reset.di --- Cmd: ${HOSTDIR}/forth ${HOSTDIR}/../build/builder.dic ../reset.bth --- Rebuilding start.di --- Cmd: ${HOSTDIR}/forth ${HOSTDIR}/../build/builder.dic ../start.bth --- Rebuilding kernel.dic --- Cmd: ${HOSTDIR}/forth ${HOSTDIR}/../build/builder.dic ../kernel.bth --- Saving kernel.dic --- --- Rebuilding tools.dic --- Cmd: ${HOSTDIR}/x86forth ${BP}/cpu/x86/build/kernel.dic ../tools.bth --- Saving tools.dic --- --- Rebuilding basefw.dic --- Cmd: ${HOSTDIR}/x86forth ${BP}/cpu/x86/build/tools.dic ../basefw.bth --- Saving basefw.dic --- --- Rebuilding bootsec.hex --- Cmd: ${HOSTDIR}/forth ${HOSTDIR}/../build/builder.dic ../bootsec.bth 1fe 1f0 400 400 --- Rebuilding fw.img --- Cmd: ${HOSTDIR}/x86forth ${BP}/cpu/x86/build/basefw.dic ../fw.bth ${BP}/cpu/x86/pc/biosload/rmenter.fth:152: >off ? make: *** [ofw.c32] Error 1 -- Regards, Robert Davidson.
