Re: Configuring GCC build: doc patch

[Hugh Sasse Staff Elec Eng <hgs at dmu dot ac dot uk>]

I said I would report what happened.  I found that having rebuilt
with ksh my compiler still would not build the FOX library, whereas
the Sun Workshop compiler will, and it fails with a segfault.  So
reading more about this I find I should really be using -xildoff
-xarch=v9 options for Sparc V9.  I try this and the build fails.  I
have tried to force the build to use the Sun assembler and linker
rather than the GNU one, because I probably built them with a badly
config'd gcc in the past.  My build script now looks like this:

<quote>
#!/bin/ksh

PATH=/bin:/progs/SUNWspro/bin:/usr/sbin:/usr/ccs/bin:/etc:/usr/local/bin:/opt/sfw/bin:/usr/openwin/bin
export PATH

ONFIG_SHELL=/bin/ksh
export CONFIG_SHELL
BUILDINGVER=3.4.1
BUILD_DIR=/export/home/Scratch/hgs/gcc-build
GCC_SOURCE_DIR=/export/home/Scratch/hgs/gcc-${BUILDINGVER}

CC="/progs/SUNWspro/bin/cc -xildoff -xarch=v9"
export CC


MAKE=/usr/local/bin/gmake
export MAKE

ASOPT="--with-as=/usr/ccs/bin/as"
LDOPT="--with-ld=/usr/ccs/bin/ld"
LANGOPT="--enable-languages=c,c++,f77,java,objc"

cd $BUILD_DIR
/bin/rm -rf ./*
${GCC_SOURCE_DIR}/configure $ASOPT $LDOPT $LANGOPTS --disable-nls && \
gmake --jobs=5 bootstrap-lean && \
gmake check

and results in

Does anything stick out like a sore thumb?

        Thank you,
