Building MINGW-w64
... for idiots. This guide is provided for those who have no clue how to compile gcc, but still want to do it. It's a reference, just follow the steps and you get what you want. There's no support for special wishes ;-)

Setting up the build environment
Download and install MSYS. You will need the following packages:
- msysCORE-1.0.14-1-msys-1.0.14-bin.tar.lzma
- coreutils-5.97-2-msys-1.0.11-bin.tar.lzma
- bash-3.1.17-2-msys-1.0.11-bin.tar.lzma
- bison-2.4.1-1-msys-1.0.11-bin.tar.lzma
- flex-2.5.35-1-msys-1.0.11-bin.tar.lzma
- gawk-3.1.7-1-msys-1.0.11-bin.tar.lzma
- grep-2.5.4-1-msys-1.0.11-bin.tar.lzma
- sed-4.2.1-1-msys-1.0.11-bin.tar.lzma
- make-3.81-2-msys-1.0.11-bin.tar.lzma
- m4-1.4.13-1-msys-1.0.11-bin.tar.lzma
- gcc-core-3.4.5-20060117-3.tar.gz
- gcc-g++-3.4.5-20060117-3.tar.gz
- binutils-2.20.1-2-mingw32-bin.tar.gz
- mingwrt-3.18-mingw32-dev.tar.gz
- w32api-3.14-mingw32-dev.tar.gz
- libregex-1.20090805-1-msys-1.0.11-dll-1.tar.lzma
- tar-1.22-1-msys-1.0.11-bin.tar.lzma
- diffutils-2.8.7.20071206cvs-2-msys-1.0.11-bin.tar.lzma
- gettext-0.17-1-msys-1.0.11-dev.tar.lzma
- libiconv-1.13.1-1-mingw32-dev.tar.lzma
Download all packages and extract them into c:\MSYS (or similar). You can unpack the .tar.lzma files using the latest version of 7zip.
Extract libiconv-1.13.1-1-mingw32-dev.tar.lzma into the mingw subfolder of the MSYS root (Why? Because!)
Getting the sources
Download all the sources into subfolders of /home/YourName/src
- binutils (version 2.20.51 or newer) -> home/YourName/src/binutils
- gcc-core (version 4.5.0 or newer) -> home/YourName/src/gcc
- gcc-g++ (version 4.5.0 or newer) -> home/YourName/src/gcc
- mingw-w64 [1] -> home/YourName/src/mingw-w64
- MPFR (version 2.4.2) -> home/YourName/src/mpfr
- GMP (version 5.0.1) -> home/YourName/src/gmp
- MPC (version 0.8.1) -> home/YourName/src/mpc
Note
Copy the src/mingw-w64/mingw-w64-headers/include directory to /RosBE64/mingw and to /RosBE64/x86_64-w64-mingw32 (64 bit) or /RosBE64/i686-w64-mingw32 (32 bit).
Patching the sources
You need to apply 2 patches (Kudos go to Kai Tietz from mingw-w64):
- Patch for binutils (Obsolete with recent Nightlies)
- Patch for gcc (Obsolete with gcc 4.6.0 Tree)
Building
Optionally set buildflags:
export CFLAGS="-O2 -pipe -fomit-frame-pointer" export CXXFLAGS="-O2 -pipe -fomit-frame-pointer" export LDFLAGS=-s
Building GMP
Create a build subdirectory for gmp:
cd build mkdir gmp cd gmp
From the build directory run the gmp configure script:
64 bit:
../../src/gmp/configure --prefix=/support --host=x86_64-w64-mingw32 --build=i686-w64-mingw32 --disable-shared
32 bit:
../../src/gmp/configure --prefix=/support --host=i686-w64-mingw32 --build=i686-w64-mingw32 --disable-shared
Now build the whole stuff.
make
Finally install it into the designated directory.
make install
Building MPFR
Create a build subdirectory for mpfr:
cd build mkdir mpfr cd mpfr
From the build directory run the mpfr configure script:
64 bit:
../../src/mpfr/configure --prefix=/support --host=x86_64-w64-mingw32 --build=i686-w64-mingw32 --with-gmp=/support --disable-shared
32 bit:
../../src/mpfr/configure --prefix=/support --host=i686-w64-mingw32 --build=i686-w64-mingw32 --with-gmp=/support --disable-shared
Now build the whole stuff.
make
Finally install it into the designated directory.
make install
Building MPC
Create a build subdirectory for mpc:
cd build mkdir mpc cd mpc
From the build directory run the mpc configure script:
64 bit:
../../src/mpc/configure --prefix=/support --host=x86_64-w64-mingw32 --build=i686-w64-mingw32 --with-gmp=/support --with-mpfr=/support --disable-shared
32 bit:
../../src/mpc/configure --prefix=/support --host=i686-w64-mingw32 --build=i686-w64-mingw32 --with-gmp=/support --with-mpfr=/support --disable-shared
Now build the whole stuff.
make
Finally install it into the designated directory.
make install
Building binutils
Create a build subdirectory for binutils:
cd build mkdir binutils cd binutils
From the build directory run the binutils configure script:
64 bit:
../../src/binutils/configure --prefix=/RosBE64 --target=x86_64-w64-mingw32 --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE64
32 bit:
../../src/binutils/configure --prefix=/RosBE64 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=i686-w64-mingw32 --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE64
Now build the whole stuff.
make
Finally install it into the designated directory.
make install
Building gcc-core
Emter into the build directory:
cd .. mkdir gcc cd gcc
Now run the configure script:
64 bit:
../../src/gcc/configure --prefix=/RosBE64 --target=x86_64-w64-mingw32 --with-gmp=/support --with-mpfr=/support --with-mpc=/support --with-pkgversion="RosBE-Windows" --enable-languages=c,c++ --enable-checking=release --enable-version-specific-runtime-libs --disable-win32-registry --disable-shared --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE64
32 bit:
../../src/gcc/configure --prefix=/RosBE64 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=i686-w64-mingw32 --with-gmp=/support --with-mpfr=/support --with-mpc=/support --with-pkgversion="RosBE-Windows" --enable-languages=c,c++ --enable-checking=release --enable-version-specific-runtime-libs --disable-win32-registry --disable-shared --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE64
Compile the gcc-core
make all-gcc
And install it
make install-gcc
Finally add it to the PATH variable.
PATH=$PATH:/RosBE64/bin ; export PATH
Building the crt
Create a build directory.
cd .. mkdir mingw-w64-crt cd mingw-w64-crt
Run the configure script
64 bit:
../../src/mingw-w64/mingw-w64-crt/configure --prefix=/RosBE64 --host=x86_64-w64-mingw32 --with-sysroot=/RosBE64
32 bit:
../../src/mingw-w64/mingw-w64-crt/configure --prefix=/RosBE64 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --with-sysroot=/RosBE64
Compile
make
And install
make install
Copy the /RosBE64/x86_64-w64-mingw32 (64 bit) or /RosBE64/i686-w64-mingw32 (32 bit) directory to /RosBE64/mingw.
Building the rest of gcc
Enter into the gcc build directory.
cd .. cd gcc
And compile the rest.
make make install
Common errors
When compiling crt:
configure: error: Please check if the mingw-w64 header set and the build/host option are set properly.
- Check if you have copied the mingw-headers/include directory to both /RosBE64/x86_64-w64-mingw32 and /RosBE64/mingw
- Check if you have set the PATH variable to the new compiler correctly
- Check if you have installed the new compiler correctly ("make install-gcc")
