Here is a patch to the README file to document my experiment with MinGW cross build.
Please feel free to change it if you think it needs some modifications. Tips For Building From The Subversion Repository ************************************************ Building OpenOCD from a repository requires a recent version of the GNU autotools (autoconf >= 2.59 and automake >= 1.9). For building on Windows, you have to use Cygwin. Make sure that your PATH environment variable contains no other locations with Unix utils (like UnxUtils) - these can't handle the Cygwin paths, resulting in obscure dependency errors. This was an observation gathered from the logs of one user; please correct us if this is wrong. 1) Run './bootstrap' to create the 'configure' script and prepare the build process for your host system. 2) Run './configure --enable-maintainer-mode' with other options. (my patch follows). The following URL is a good reference if you want to build OpenOCD under cygwin. http://forum.sparkfun.com/viewtopic.php?t=11221 Alternatively you can build the Windows binary under Linux using MinGW cross compiler. The following documents some tips of using this cross build option. a) libusb-win32 You can choose to use the libusb-win32 binary distribution from its Sourceforge page. As of this writing, the latest version is 0.1.12.2. This is the recommend version to use since it fixed an issue with USB composite device and this is important for FTDI based JTAG debuggers. http://sourceforge.net/projects/libusb-win32/ You need to download the libusb-win32-device-bin-0.1.12.2.tar.gz package. Please extract this file into a temp directory. Copy the file libusb-win32-device-bin-0.1.12.2\include\usb.h to your MinGW include directory. Copy the library libusb-win32-device-bin-0.1.12.2\lib\gcc\libusb.a to your MinGW library directory. Take note that different Linux distros often have different MinGW installation directory. Some of them also put the library and include into a seperate sys-root directory. If there is a new svn version of libusb-win32, you can build it as well. This is the instrunction from the libusb-win32 Makefile. # If you're cross-compiling and your mingw32 tools are called # i586-mingw32msvc-gcc and so on, then you can compile libusb-win32 # by running # make host_prefix=i586-mingw32msvc all b) libftdi libftdi source codes can be download from the following website. http://www.intra2net.com/en/developer/libftdi/download.php It does not provide Windows binary. You can build it from the source tarball or the git tree. If you are using the git tree, the following is the instruction from README.mingw. You need to have cmake installed. - Edit Toolchain-mingw32.cmake to point to the correct MinGW installation. - Create a build directory like "mkdir build-win32", e.g in ../libftdi/ - cd in that directory and run "cmake -DCMAKE_TOOLCHAIN_FILE=../Toolchain-mingw32.cmake .." - Copy src/ftdi.h to your MinGW include directory. - Copy build-win32/src/*.a to your MinGW lib directory. c) OpenOCD Now you can build OpenOCD under Linux using MinGW. You need to use --host=your_mingW_prefix in the configure option. Example for libftdi (in one line, tested under Ubuntu 9.04): ./configure --host=i586-mingw32msvc --enable-maintainer-mode --disable-shared --enable-ft2232_libftdi Example for ftd2xx (in one line, tested under Ubuntu 9.04) ./configure --host=i586-mingw32msvc --enable-maintainer-mode --disable-shared --enable-ft2232_ftd2xx --with-ftd2xx-win32-zipdir=/home/mcuee/Desktop/build/openocd/libftd2xx-win32 -- Xiaofan http://mcuee.blogspot.com
