I guess mine counts as successful, it works in that I can compile simple
hello-world C++ programs, but I haven't tried running them, I don't yet
have cygwin on my box (yet to install windows...).
Below, /asis is untarred GNU releases. ~/dev/cygwin/src is my cygwin
repository checkout.
Here we go -- get sources first:
mkdir -p /home/lat/dev/gnu/src/gcc-3.2.2/linux-x-cygwin
cd !$
lndir /asis/src/GNU.LANG/gcc-3.2.2 .
rm -fr libiberty
mkdir cygwin
lndir ~/dev/cygwin/src cygwin
cd cygwin
mv bfd binutils gas intl libiberty ld mmalloc newlib opcodes winsup ..
cd include
for f in *.h */; do
[ -e ../../include/$f ] && rm -f ../../include/$f;
done
cd ..
mv include/* ../include
cd ..
rm -fr cygwin
rm libiberty/cplus-dem.c
ln -s /asis/src/GNU.LANG/gcc-3.2.2/libiberty/cplus-dem.c libiberty
Build Cygwin cross compiler:
mkdir -p /home/lat/dev/gnu/build/gcc-3.2.2/linux-x-cygwin
cd !$
../../../src/gcc-3.2.2/linux-x-cygwin/configure \
--prefix=/home/lat/dev/gnu/linux-x-cygwin \
--host=i686-pc-linux-gnu --build=i686-pc-linux-gnu \
--target=i686-pc-cygwin --with-gnu-ld --with-gnu-as \
--enable-threads=no --with-mmap --enable-bfd-assembler \
--enable-languages="c,c++"
make -kj4 cross
make -kj4 cross
make -kj4 install-cross
# Edit the specs (*startfile:) for full path to *crt.o (two places)
