How to get very basic offline compiling on OS X

Hugo, I'm very interested in building mbed code using their libraries, but using offline compilation on Mac OS X. I don't even know where to get the libraries. Can you point me at the right location? Thanks!Hugo Vincent wrote:
Being arm-eabi-* instead of plain old arm-elf-* means you should be able to link against the mbed libraries (although I've never tried).
You can get the header files and binary libraries by checking out with Subversion (svn) from here: http://mbed.org/projects/libraries/svn/mbed/trunk

Beyond that, like I said, I've never tried and don't know, sorry. I have heard of others who tried and failed so I presume it's not completely trivial. But you can verify that the GNU tools can read the libraries in that format; for example:
arm-none-eabi-nm --print-armap LPC1768/mbed.arprints a full list of symbols in the library.

Now that mbed officially support GCC export, you can just install GCC for ARM from here: https://launchpad.net/gcc-arm-embedded then download/export a project from the online compiler, unzip it, and run "make".
Have you got that to work, I had problems?

It does work! Maybe I forgot to update the mbed lib last time i tried !
Hi Guys,
After spending some hours trying to get this working from info on the informationSuperDirtTrack I have come up with a simple solution that works, here you go:
First install MacPorts if you have not done so. See: http://www.macports.org/
Then install arm-elf-gcc:
sudo port install arm-elf-gcc
Then check it is installed correctly:
arm-elf-gcc-4.5 --version
should produce:
arm-elf-gcc-4.5 (GCC) 4.5.0

Next we need to make some symbolic links, most code you see seems to use arm-none-eabi so we need to map this to arm-elf:
cd /opt/local/bin/
sudo ln -s arm-elf-gcc-4.5 arm-none-eabi-gcc
sudo ln -s arm-elf-as arm-none-eabi-as
sudo ln -s arm-elf-ld arm-none-eabi-ld
sudo ln -s arm-elf-objcopy arm-none-eabi-objcopy
sudo ln -s arm-elf-size arm-none-eabi-size
Get basic CMIS stuff here (section 5 zip file): http://dev.frozeneskimo.com/notes/compiling_your_own_cmsis_code_for_the_mbed
in the unzipped folder:
make
cp mbed_test.bin /Volumes/MBED
Reset your mBed and you should see the blinking light. It is going at the wrong speed, some issue with the timer stuff.
Cheers Andy
