For example, you can configure OpenOCD to +cross-compile on a x86 Linux host to run on Windows (MinGW32), you could +use the following configuration options: + + ./configure --build=i686-pc-linux-gnu --host=i586-mingw32msvc ... + +Likewise, the following options allow OpenOCD to be cross-compiled for +an ARM target on the same x86 host: + + ./configure --build=i686-pc-linux-gnu --host=arm-elf ... + +Both must be specified to work around bugs in autoconf. + +Scripts for producing ARM cross-compilers can be found on the web with a +little searching. A script to produce an x86 Linux-hosted MinGW32 +cross-compiler can be downloaded from the following URL: + + http://www.mingw.org/wiki/LinuxCrossMinGW + Configuration Options ---------------------
