- Subject: building a cross-compiler for Linux/OSX
Hi folks!
I'm trying to build a cross-compiler under Linux and MacOSX using this
script: http://sourceware.org/ml/cygwin/2010-08/txt00010.txt
I get the same error on Linux and MacOSX after the make of line 340:

Anyone able to run the script to completion or a different (and working) way
to build a cross-compiler for cygwin on Linux and OSX?
