I'm trying to build a NIOS2 toolchain using the procedure found
on the eCos web site. Everything builds fine under Linux, but
under Cygwin, I can't get gcc to build. Specifically, the
build of libstdc++ fails.
Here's how I'm building gcc:
TARGET=nios2-elf
DEST=/opt/gnu
rm -rf src
tar xjvf nios2_60_gnusrc_win.tar.bz2
function build-gcc
{
mv src/newlib/newlib src/gcc
mv src/newlib/libgloss src/gcc
cp src/gcc/newlib/configure.host.normalc src/gcc/newlib/configure.host
rm -rf gcc-build
mkdir gcc-build
pushd gcc-build
mkdir -p gcc/doc
cp -p ../src/gcc/gcc/doc/*.1 gcc/doc
../src/gcc/configure --target=$TARGET \
--prefix=$DEST --enable-languages=c,c++ \
--with-gnu-as --with-gnu-ld --with-newlib \
--with-gxx-include-dir=$DEST/$TARGET/include \
--disable-multilib
-v 2>&1 | tee configure.out
PATH=$PATH:$DEST/bin make -w all 2>&1 | tee make.out
PATH=$PATH:$DEST/bin make -w install 2>&1 | tee install.out
popd
}
build-gcc
[I had to disable multilib to get the make to run in a
reasonable amount of time. If I leave multilib enabled, it
takes about 30 hours for the build to get to the point where it
fails.]
During the "make -w", there's an internal compiler failure when
libstdc++ .h files are begin pre-compiled. Has anybody run
into a problem like this before? I looked at the line in the
.h file where gcc segfaults, and I don't see anything wrong.
