Hi,
I'm trying to build the RedHat version of GCC for msp430 under Ubuntu
13.04, with no luck so far. I'm stuck with building newlib, it throws the
following error:
make[8]: Entering directory
`/home/arqui/mspgcc-install2/msp430-newlib/msp430-elf/430/newlib/libc/argz'

I'm building it based on these instructions:
http://sourceforge.net/apps/mediawiki/mspgcc/index.php?title=Install:redhat .
Both binutils and gcc were built with no errors.
The commands I ran up to that point are the following:
### binutils ###
################
BINUTILS_PREFIX='binutils-2.24'
wget http://ftp.gnu.org/gnu/binutils/$BINUTILS_PREFIX.tar.gz
tar xvf $BINUTILS_PREFIX.tar.gz
mkdir -p msp430-binutils
# Configure Binutils
cd msp430-binutils
# We need to build binutils for the msp430
../$BINUTILS_PREFIX/configure --target=msp430-elf
# build binutils
make
# Do the install as root (e.g., sudo)
sudo make install
cd ..
### GCC ###
###########
mkdir -p gcc-trunk
cd gcc-trunk
# Check out GCC from SVN
svn checkout svn://gcc.gnu.org/svn/gcc/trunk .
# Get GCC prerequisites
./contrib/download_prerequisites
cd ..
mkdir -p msp430-gcc
cd msp430-gcc
# The exact path here might be different
../gcc-trunk/configure --target=msp430-elf --enable-languages=c,c++
--with-newlib=yes
# Note, you must make all-gcc and install-gcc anything else seems to break.
make all-gcc
# Do the install as root (e.g., sudo)
sudo make install-gcc
cd ..
mkdir -p newlib
cd newlib
cvs -z 9 -d :pserver:anon...@sourceware.org:/cvs/src login
cvs -z 9 -d :pserver:anon...@sourceware.org:/cvs/src co newlib
cd ..
mkdir -p msp430-newlib
# Now Build Newlib for MSP430 (Since this isn't going to run linux or
similar OS, we don't need syscalls)
cd msp430-newlib
../newlib/src/configure --target=msp430-elf
make
sudo make install
cd ..
Am I missing something? I saw that binutils had some changes regarding the
mcpu option detection (link:
https://www.sourceware.org/ml/binutils/2014-01/msg00295.html). Should I
specify '430' as the mcpu option? Thanks in advance for your help.
Kind regards,
Jose
