Hi there,
I am a newbie at building a cross compiler so I'm trying
to read everything I can find, but I've failed in all my
attempts to build a Linux gcc cross-compiler than runs
on Solaris. Here is my simple script,
#!/bin/ksh
GCC=gcc-2.95.3
BINUTILS=binutils-2.10.1
TARGET=i686-pc-linux-gnu
SRCDIR=/home/davidt/gnu/src/sun
BINDIR=/home/davidt/gnu/bin/sun
cd $SRCDIR
mkdir build-binutils build-gcc
# configure, build and install binutils
cd build-binutils
../$BINUTILS/configure --target=$TARGET --prefix=$BINDIR -v
make all install
# configure, build and install gcc
cd ../build-gcc
../$GCC/configure --target=$TARGET --prefix=$BINDIR -v
make all install
I have untarred the packages into /home/davidt/gnu/bin/sun,
and binutils builds fine. The error I get is from building
gcc, here is the [slightly formatted] error output,
for name in _muldi3 _divdi3 _moddi3 _udivdi3 _umoddi3 _negdi2 _lshrdi3 \
_ashldi3 _ashrdi3 _ffsdi2 _udiv_w_sdiv _udivmoddi4 _cmpdi2 _ucmpdi2 \
_floatdidf _floatdisf _fixunsdfsi _fixunssfsi _fixunsdfdi _fixdfdi \

_fixtfdi _fixunstfdi _floatditf __gcc_bcmp _varargs __dummy _eprintf \
_bb _shtab _clear_cache _trampoline __main _exit _ctors _pure; \
do \
echo ${name}; \

../../gcc-2.95.3/gcc/libgcc2.c:42: unistd.h: No such file or directory
make[1]: *** [libgcc2.a] Error 1
make[1]: Leaving directory `/home/davidt/gnu/src/sun/build-gcc/gcc'
make: *** [all-gcc] Error 2
I don't understand why stdlib.h & unistd.h cannot be found. I need
help, what am I doing wrong? Any advice or URLs that would help me
(the above script is from http://www.objsw.com/CrossGCC) would be
extremely appreciated.
