Here is a work in progress patch for those building X64 or IA32 targets from Windows. It allows building with gcc instead of a Microsoft compiler. Building has been tested with Windows 7 x64 using MINGW archives from http://www.drangon.org/mingw/ or http://sourceforge.net/projects/mingw-w64-dgn/files/mingw-w64/
Unpack mingw-w32-bin-i686-20140425.7z and set environment variable mingw32 to its path. Unpack mingw-w64-bin-x86_64-20140425.7z and set environment variable mingw64 to its path. Apply the patch then build using -t MINGW. It's that easy. No unix shell port is involved. Just build from a cmd.exe prompt as normal. Because mingw requires no install or setup, your registry, path and other environment variables are unaffected. The MINGW port of gcc brings C99 support to those using Windows to develop EDK2 code. Wouldn't it be nice if one day UEFI could drop support for non-C99 compilers so that C99 features could be used in the code? There is actually a lot of work to be done before gcc could replace Microsoft tools. One problem is that some UEFI source level debuggers understand only Microsoft debug information. Another problem is that right now gcc is producing bigger code. Getting gcc link time optimization working may solve this problem. Build speed with MINGW is not quite as fast as with Microsoft tools, but it is reasonable. For example, a test of 18 builds that takes 523 seconds using VS2008 takes 694 seconds using MINGW. Here are build test results. Failing builds: build.exe -p D:\uefi\buildtest-011\edk2\OvmfPkg\OvmfPkgX64.dsc -b DEBUG -t MINGW -n 16 -a X64 -DSECURE_BOOT_ENABLE -DFD_SIZE_2MB build.exe -p D:\uefi\buildtest-011\edk2\OvmfPkg\OvmfPkgIA32X64.dsc -b DEBUG -t MINGW -n 16 -a IA32 -a X64 -DSECURE_BOOT_ENABLE -DFD_SIZE_2MB These fail because 'the required fv image size 0x80ce50 exceeds the set fv image size 0x800000' Here are passing results: build.exe -p D:\uefi\buildtest-011\edk2\OvmfPkg\OvmfPkgX64.dsc -b RELEASE -t MINGW -n 16 -a X64 -DSECURE_BOOT_ENABLE -DFD_SIZE_2MB build.exe -p D:\uefi\buildtest-011\edk2\OvmfPkg\OvmfPkgIA32.dsc -b DEBUG -t MINGW -n 16 -a IA32 -DSECURE_BOOT_ENABLE -DFD_SIZE_2MB build.exe -p D:\uefi\buildtest-011\edk2\OvmfPkg\OvmfPkgIA32.dsc -b RELEASE -t MINGW -n 16 -a IA32 -DSECURE_BOOT_ENABLE -DFD_SIZE_2MB build.exe -p D:\uefi\buildtest-011\edk2\OvmfPkg\OvmfPkgIA32X64.dsc -b RELEASE -t MINGW -n 16 -a IA32 -a X64 -DSECURE_BOOT_ENABLE -DFD_SIZE_2MB build.exe -p D:\uefi\buildtest-011\edk2\AppPkg\AppPkg.dsc -b DEBUG -t MINGW -n 16 -a X64 build.exe -p D:\uefi\buildtest-011\edk2\AppPkg\AppPkg.dsc -b RELEASE -t MINGW -n 16 -a X64 build.exe -p D:\uefi\buildtest-011\edk2\AppPkg\AppPkg.dsc -b DEBUG -t MINGW -n 16 -a IA32 build.exe -p D:\uefi\buildtest-011\edk2\AppPkg\AppPkg.dsc -b RELEASE -t MINGW -n 16 -a IA32 build.exe -p D:\uefi\buildtest-011\edk2\IntelFspPkg\IntelFspPkg.dsc -b DEBUG -t MINGW -n 16 -a IA32 build.exe -p D:\uefi\buildtest-011\edk2\IntelFspPkg\IntelFspPkg.dsc -b RELEASE -t MINGW -n 16 -a IA32 build.exe -p D:\uefi\buildtest-011\edk2\DuetPkg\DuetPkgX64.dsc -b DEBUG -t MINGW -n 16 -a X64 build.exe -p D:\uefi\buildtest-011\edk2\DuetPkg\DuetPkgIA32.dsc -b DEBUG -t MINGW -n 16 -a IA32 build.exe -p D:\uefi\buildtest-011\edk2\ShellPkg\ShellPkg.dsc -b DEBUG -t MINGW -n 16 -a X64 build.exe -p D:\uefi\buildtest-011\edk2\ShellPkg\ShellPkg.dsc -b RELEASE -t MINGW -n 16 -a X64 build.exe -p D:\uefi\buildtest-011\edk2\ShellPkg\ShellPkg.dsc -b DEBUG -t MINGW -n 16 -a IA32 build.exe -p D:\uefi\buildtest-011\edk2\ShellPkg\ShellPkg.dsc -b RELEASE -t MINGW -n 16 -a IA32 For a test using real hardware, I used the Duet project and ASRock E350M1 motherboard. A modified Duet was used (http://notabs.org/coreboot/duet-payload/index.htm) because the standard Duet has some problems on real hardware, and because the code size is too big when gcc is used. This test passes. Here are some notes about the patch: 1) IPF is not supported. 2) 32-bit target code builds, but has not been tested. 3) Code size is a little big, causing problems with projects such as Duet. Getting the gcc -flto option to work might make the code size similar to that of the Microsoft tools. 4) GenMake.py had to be patched to fix a back/forward slash issue. 5) Lack of weak external support made the EfiSocketLib build fail. The patch works around the problem. 6) The new Thunk16.nasm causes ld to crash. The patch reverts back to Thunk16.S for now. A better solution to this problem must be found. 7) StdLib\Include\X64\machine\limits.h assumes long int has 64 bits any time __GNUC__ is defined. The patch fixes this for the MINGW case.
