Open Source IDE and Toolchain for the STM32F4 Discovery on Mac OSX Lion

The sample LD file inside of the firmware package supplied by ST worked well
in my GCC (Code Surcery) environment:

Kind regards

I’m hanging at step 2:
2. Install Sourcery G++ lite.
There are only 2 versions to download: Linux and Windows.
But what do I install on the Mac? Where do get I get the Macos version?

Does this work with Mac OS X 10.7 (Lion) as well?

How are you able to load the binary and debug? Are you using OpenOCD?

First, let me thank you for putting together this awesome tutorial – just the sort of thing I was looking for!

I’m trying to install this on a 10.7.4 system and am hitting errors during the binutils build. Specifically I’m failing with:

/bin/sh ./libtool –tag=CC –mode=compile clang -DHAVE_CONFIG_H -I. -I../../../binutils-2012.03/bfd -I. -I../../../binutils-2012.03/bfd -I../../../binutils-2012.03/bfd/../include -DHAVE_bfd_elf32_littlearm_vec -DHAVE_bfd_elf32_bigarm_vec -DHAVE_bfd_elf32_little_generic_vec -DHAVE_bfd_elf32_big_generic_vec -DBINDIR='”/Users/holland/arm-cs-tools/bin”‘ -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -g -O2 -MT dwarf2.lo -MD -MP -MF .deps/dwarf2.Tpo -c -o dwarf2.lo -DDEBUGDIR=\”/Users/holland/arm-cs-tools/lib/debug\” ../../../binutils-2012.03/bfd/dwarf2.c

./libtool: line 519: CDPATH: command not found
./libtool: line 519: CDPATH: command not found
./libtool: line 519: CDPATH: command not found
libtool: Version mismatch error. This is libtool 2.2.7a, but the
libtool: definition of this LT_INIT comes from an older release.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.7a
libtool: and run autoconf again.

Any suggestions as to where I might look to fix this? Hoping I don’t have to figure out how to install an older version of libtool 🙂

Thank you for your help!

Removed macports, reinstalled all the packages using homebrew, and now getting a different error on compile:

make: *** No rule to make target `cross-g++’. Stop.

Thanks. Is there a assembled toolchain? Cuz i can’t do it myself. I want to download completed IDE)))
