Hi again, and thanks again for your help.

Going back to the possibility of compiling libada for i686-elf target,
please bear with me just in case you might be able to help me with the
sysroot, this is what I have done so far:

From a standard Cygwin installation and with the src files in /usr/srx

export PREFIX=/usr/cross
export TARGET=i686-elf
cd /usr/src
mkdir build-binutils build-gcc

After successfully building the binutils then:

cd /usr/src/build-gcc
export PATH=$PATH:$PREFIX/bin
../gcc-4.3.4/configure --target=$TARGET --prefix=$PREFIX --disable-nls
--enable-languages=c,c++,ada --without-headers
make all-gcc
make install-gcc

then:

make all-target-libgcc
make install-target-libgcc

then:

make all-target-libada

Where it fails trying to do the make -C rts.

Where should I be setting the sysroot directory?

Kind regards, Alexis.
