... 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:

  • MSYS-w64 (version 20100707)
  • make (version 3.82)
  • Recent mingw-w64 32 bit Toolchain (here)

Download all packages and extract them into c:\MSYS (or similar).

Additional step needed is: Go to the bin folder inside msys and rename i686-w64-*.exe to *.exe to make configure happy

Getting the sources

Download all the sources into subfolders of /src

  • MPFR (version 3.0.0) -> /src/mpfr
  • GMP (version 5.0.1) -> /src/gmp
  • MPC (version 0.8.2) -> /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):

Building

Optionally set buildflags:

export CFLAGS="-g0 -O2 -pipe -Wl,-S -Wl,-lmsvcrt"
export CXXFLAGS="-g0 -O2 -pipe -Wl,-S -Wl,-lmsvcrt"

Building GMP

Create a build subdirectory for gmp:

cd build
mkdir gmp
cd gmp

From the build directory run the gmp configure script:

../../src/gmp/configure --prefix=/support --host=i686-w64-mingw32 --build=i686-w64-mingw32 --disable-shared --disable-werror

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:

../../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:

../../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 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=x86_64-w64-mingw32
 --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE64 --with-stabs

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 --with-stabs

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 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --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 --enable-sjlj-exceptions --with-stabs

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 --build=i686-w64-mingw32 --with-sysroot=/RosBE64 
--disable-werror

32 bit:

../../src/mingw-w64/mingw-w64-crt/configure --prefix=/RosBE64 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --with-sysroot=/RosBE64 
--disable-werror

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")
