... 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 ;-)
Contents
Setting up the build environment
Download and install MSYS. You will need the following packages:
Download all packages and install them into c:\MSYS32. Extract Toolchain to the /usr/ folder inside.
pacman -Syu
pacman -Su
pacman -S make texinfo diffutils
(If installing make makes problems, remove the files it laments about already being existent)
Getting the sources
Download all the sources into subfolders of /src
- binutils (version 2.32 -> /src/binutils
- gcc (version 7.4.0 -> /src/gcc
- mingw-w64 v6.0.0 (here) -> /src/mingw-w64
- MPFR (version 4.0.2) -> /src/gcc/mpfr
- GMP (version 6.1.2) -> /src/gcc/gmp
- MPC (version 1.1.0) -> /src/gcc/mpc
Note
Copy the src/mingw-w64/mingw-w64-headers/include directory to /RosBE/mingw and to /RosBE/x86_64-w64-mingw32 (64 bit) or /RosBE/i686-w64-mingw32 (32 bit).
This is needed for building GCC. This is replaced by make install of the MinGW headers, but before that step GCC still wants headers which we give it here.
Building
Optionally set buildflags:
64 bit:
export CFLAGS="-g0 -O2 -pipe -Wl,-S" export CXXFLAGS="-g0 -O2 -pipe -Wl,-S"
32 bit:
export CFLAGS="-g0 -O2 -pipe -Wl,-S -march=pentium -mtune=i686" export CXXFLAGS="-g0 -O2 -pipe -Wl,-S -march=pentium -march=i686"
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=/RosBE --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=x86_64-w64-mingw32 --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE
32 bit:
../../src/binutils/configure --prefix=/RosBE --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=i686-w64-mingw32 --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE
Now build the whole stuff.
make
Finally install it into the designated directory.
make install
Building gcc-core
Enter into the build directory:
cd .. mkdir gcc cd gcc
Now run the configure script:
64 bit:
../../src/gcc/configure --prefix=/RosBE --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=x86_64-w64-mingw32 --with-pkgversion="RosBE-Windows" --enable-languages=c,c++ --enable-checking=release --disable-win32-registry --disable-shared --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE --enable-version-specific-runtime-libs --with-host-libstdcxx="-lstdc++ -lsupc++"
32 bit:
../../src/gcc/configure --prefix=/RosBE --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=i686-w64-mingw32 --with-pkgversion="RosBE-Windows" --enable-languages=c,c++ --enable-checking=release --disable-win32-registry --disable-shared --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE --enable-version-specific-runtime-libs --with-host-libstdcxx="-lstdc++ -lsupc++"
Compile the gcc-core
make all-gcc
And install it
make install-gcc
Finally add it to the PATH variable.
export PATH="$PATH:/RosBE/bin"
Building the mingw-w64 headers
Create a build directory.
cd .. mkdir mingw-w64-headers cd mingw-w64-headers
Run the configure script
64 bit:
../../src/mingw-w64/mingw-w64-headers/configure --host=x86_64-w64-mingw32 --build=i686-w64-mingw32 --prefix=/RosBE/x86_64-w64-mingw32
32 bit:
../../src/mingw-w64/mingw-w64-headers/configure --host=i686-w64-mingw32 --build=i686-w64-mingw32 --prefix=/RosBE/i686-w64-mingw32
Install
make install
Run the configure script
64 bit:
../../src/mingw-w64/mingw-w64-headers/configure --host=x86_64-w64-mingw32 --build=i686-w64-mingw32 --prefix=/RosBE
32 bit:
../../src/mingw-w64/mingw-w64-headers/configure --host=i686-w64-mingw32 --build=i686-w64-mingw32 --prefix=/RosBE
Install
make install
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=/RosBE/x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --build=i686-w64-mingw32 --with-sysroot=/RosBE
32 bit:
../../src/mingw-w64/mingw-w64-crt/configure --prefix=/RosBE/i686-w64-mingw32 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --with-sysroot=/RosBE
Compile
make
And install
make install
Copy the /RosBE/x86_64-w64-mingw32 (64 bit) or /RosBE/i686-w64-mingw32 (32 bit) directory to /RosBE/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 /RosBE/x86_64-w64-mingw32 and /RosBE/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")
