lundmans Toolchain Guide Addition

[techy]

I've been working on trying to get lundman's guide to compile g++ properly but was unable to by following his instructions exactly.

Guide: http://lundman.net/wiki/index.php/NMT:cross

(What I did is in bold)

Quote:--cut--
# Now recompile gcc fully.
cd ../build/
rm -rf *

# Recreate the sys-include folder by linking it to the usr/include folder (Not sure if everyone will need to but it was needed for me to even get gcc to complile.
# Then copy over the libstdc++-v3 folder from the gcc source.

ln -s /usr/local/$ARCH/$CTARGET/usr/include/ /usr/local/$ARCH/$CTARGET/sys-include
cp -R ../gcc-4.0.4/libstdc++-v3/ /usr/local/$ARCH/$CTARGET/sys-include/

../gcc-4.0.4/configure \
--target=$CTARGET \
--prefix=/usr/local/mips \
--with-sysroot=/usr/local/mips/$CTARGET \
--enable-languages=c,c++ \
--enable-shared \
--disable-checking \
--disable-werror \
--disable-__cxa_atexit \
--enable-target-optspace \
--disable-nls \
--enable-multilib \
--with-float=soft \
--enable-sjlj-exceptions \
--enable-threads=posix


# It is likely it will fail on __ctype_touplow_t*, this is quite easy to fix.
# http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14939
# I went with the #ifdef changes of ../gcc-4.0.4/libstdc++-v3/config/locale/generic/c_locale.h
# and ../gcc-4.0.4/libstdc++-v3/config/os/gnu-linux/ctype_base.h

make
make install

# You can now remove the libstdc++-v3 folder you copied over to compile g++ as it is not needed from what I can tell.

rm -rf /usr/local/$ARCH/$CTARGET/sys-include/libstdc++-v3

I'm not sure if this will work for everyone but it worked for me. A simple Hello World application in c++ (and c) ran just fine on my PCH.

Code:

/opt/sybhttpd/localhost.drives/USB_DRIVE_A-1/hello # ./hellocpp
Hello World!
/opt/sybhttpd/localhost.drives/USB_DRIVE_A-1/hello # ./helloc
Hello World!
