Looking for a little help..
I'm attempting to build the GCC3.0 cross compiler
for the powerpc-elf target on a native X86 Red Hat 7.0 Linux box.
I'm using the following:
GCC - 3.0
binutils - 2.10.1
newlib - 1.9.0
gdb - 5.0
TARGET = powerpc-elf
PREFIX = /usr/local/powerpc-elf
Common build directory for gcc, binutils, newlib -
/home/mlancisi/build_binutils
GCC Source dir -
/home/mlancisi/gcc-3.0
Thusfar I have run into two problems, both during
the complete full build of GCC (binutils, bootstrap gcc, and newlib all built
fine.. I have not yet built the debugger.. )
The first problem was with vsprintf.c in libiberty.
Command line and error as follows:
/home/mlancisi/build_binutils/gcc/xgcc
-B/home/mlancisi/build_binutils/gcc/ -B/usr/local/powerpc-elf/powerpc-elf/bin/
-B/usr/local/powerpc-elf/powerpc-elf/lib/ -isystem
/usr/local/powerpc-elf/powerpc-elf/include -c -DHAVE_CONFIG_H -g -O2 -W -Wall
-I. -I../../../gcc-3.0/libiberty/../include -W -Wall -Wtraditional
-pedantic
../../../gcc-3.0/libiberty/vsprintf.c

To get around this issue, based on some info
obtained in the crossgcc mailing list archives, I simply stubbed out vsprintf.c
(ifdeffed out actually) . I was unable to find powerpc-elf header files which
likely would have also fixed the problem.. I think I should be all set here
because I believe vsprintf is available in the standard lib... If anyone knows
different, please let me know!!!

Second issue - Once vsprintf was stubbed out, the
build continued on until it got to another problem, mentioned more recently in
the archives, as follows:
/home/mlancisi/build_binutils/gcc/xgcc
-B/home/mlancisi/build_binutils/gcc/ -nostdinc++
-L/home/mlancisi/build_binutils/powerpc-elf/nof/libstdc++-v3/src
-L/home/mlancisi/build_binutils/powerpc-elf/nof/libstdc++-v3/src/.libs
-B/usr/local/powerpc-elf/powerpc-elf/bin/
-B/usr/local/powerpc-elf/powerpc-elf/lib/ -isystem
/usr/local/powerpc-elf/powerpc-elf/include -msoft-float -mrelocatable-lib
-mno-eabi -mstrict-align -I../../../../../gcc-3.0/libstdc++-v3/../gcc
-I../../../../../gcc-3.0/libstdc++-v3/../include
-I../../../../../gcc-3.0/libstdc++-v3/include
-I../../../../../gcc-3.0/libstdc++-v3/include/std
-I../../../../../gcc-3.0/libstdc++-v3/include/c_std -I../include
-I../../../../../gcc-3.0/libstdc++-v3/libsupc++ -g -O2 -msoft-float
-mrelocatable-lib -mno-eabi -mstrict-align -fno-implicit-templates -Wall
-Wno-format -W -Wwrite-strings -Winline -fdiagnostics-show-location=once -g -c
../../../../../gcc-3.0/libstdc++-v3/libsupc++/new_op.cc -o
new_op.o ===
I found the recent discussion in the archives
regarding this issue as pertains to the powerpc-eabi cross compiler. The
question is, is there a generic fix for this as yet? Or a workaround? I'd
rather not have to go back to GCC 2.95.3 to build the powerpc-elf cross
compiler, as we use the newly released GCC3.0 for our native
compiles...
Thanks in advance for ANY help!!
