The symptom is that compilation aborts as follows
gcc-4.1.2/libssp/ssp.c: In function '__guard_setup':
../../../gcc-4.1.2/libssp/ssp.c:70: warning: implicit declaration of function
'open'
../../../gcc-4.1.2/libssp/ssp.c:70: error: 'O_RDONLY' undeclared (first use in
this function)
BACKGROUND
I am compiling a cross compiler for an ARM processor and newlib.
WORKFLOW
tar xvfz ../src/rlx_dist/newlib-1.15.0.tar.gz
tar xvfj ../src/rlx_dist/gcc-4.1.2.tar.bz2
tar xvfj ../src/rlx_dist/binutils-2.17.tar.bz2
...
cd gcc-4.1.2-arm-elf
../gcc-4.1.2/configure --srcdir=../gcc-4.1.2 --target=arm-elf \
--with-cpu=arm9 --with-newlib --disable-threads --disable-multilib \
--disable-nls --enable-languages=c \
--prefix=/rlxb2/arm-elf
PROBLEM
At this point gcc-4.1.2-arm-elf/arm-elf/libssp/config.h
does not define HAVE_FCNTL_H and neither many others.
Copying manuslly the header files from newlib-1.15.0/newlib/libc/include/
to $prefix/arm-elf/include AND manually editing
gcc-4.1.2-arm-elf/arm-elf/libssp/config.h
does the trick.
Then make and make install complete without complaining.
In any case, configure produces a disfunctional
cc-4.1.2-arm-elf/arm-elf/libssp/config.h.
For your information.
