macos - Cross-compiler for Linux on Mac OS X?

Question

I've been reading lots of documents on the internet about creating a cross compiler for linux on mac os x but can't seam to get any to work.

It seams as if no one can help me with the question: Getting GMP to work with GCC 4.5.2

Is there any easy'er way to create a cross compiler?

Answer 1

You need to:

1. install the xcode base build tools
2. install the optional xcode command line tools
3. install homebrew
4. install the homebrew build tools
   4.1 brew install crosstool-ng mpfr gmp grep
   4.2 brew tap homebrew/dupes
5. create a case sensitive volume using "disk utility"
6. use this volume to build the tool chain itself
   6.1 generate a base configuration (for me this is an arm cortex a8)
   6.1.1 ct-ng arm-cortex_a8-linux-gnueabi
   6.2 use menuconfig (ct-ng menuconfig) to tweak the configuration
   6.2.1. disable fortran and java (c compiler)
   6.2.2. turn off static linking (c compiler)
   6.2.3. change the paths to be on the volume you created above (paths and misc options)
   6.2.4. remove dmalloc (debug facilities)
   6.3 invoke the build:
   6.3.1 ulimit -n 1024
   6.3.2 ct-ng build

with much thanks to the crosstools-ng list.
