C++ STD headers not being generated for multilib arm-elf cross compiler



Hello.


I am trying to build a C++ cross compiler for arm-elf under i686-pc-mingw32. GCC built smoothly and works perfectly, however the C++ library is giving me errors. These are binutils-2.14, gcc-3.3, using newlib-1.11.0.

For gcc, I enabled thumb & thumb-interwork adding the custom MULTILIB options in t-arm-elf. Then I configured gcc with:

{gcc-dir}/configure --prefix=d:/gnu --exec-prefix=d:/gnu --host=i686-pc-mingw32 --target=arm-thumb-elf --enable-targets=arm-elf --with-cpu=arm7tdmi --enable-interwork --enable-multilib --with-newlib --disable-threads --disable-win32-registry --with-gcc --with-gnu-ld --with-gnu-as --with-stabs --with-headers=../newlib-1.11.0/newlib/libc/include --disable-shared --enable-languages=c,c++

As I said, 'make all-gcc' built gcc without problems and it works fine as much as I've tested it.

Then I built newlib configured as:

{newlib-dir}/newlib-1.11.0/configure --prefix=d:/gnu --exec-prefix=d:/gnu --target=arm-thumb-elf --
host=i686-pc-mingw32 --with-cpu=arm7tdmi --enable-multilib --enable-interwork -
-disable-threads --disable-shared --with-gnu-ld --enable-targets=arm-elf


Ditto, builds & works ok for all arm, thumb & interwork compilations.

Now, when I attempt to compile the C++ libs, the make process dies trying to compile libsupc++:

In file included from ../../../../../gcc-3.3/libstdc++-v3/libsupc++/del_op.cc:31:
../../../../../gcc-3.3/libstdc++-v3/libsupc++/new:41:19: cstddef: No such file or directory
In file included from ../../../../../gcc-3.3/libstdc++-v3/libsupc++/del_op.cc:31:
../../../../../gcc-3.3/libstdc++-v3/libsupc++/new:82: error: `size_t'
undeclared in namespace `std'
../../../../../gcc-3.3/libstdc++-v3/libsupc++/new:82: error: declaration of `
operator new' as non-function
[...lots of errors due to missing cstddef...]


I checked out and the libstdc++/include headers are not being generated... I can manually generate the header files issuing a make in the libstdc++/include dir, however I have concerns about the multilib handling of the header file construction process.

Cheers!
