... 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 /RosBE64/mingw and to /RosBE64/x86_64-w64-mingw32 (64 bit) or /RosBE64/i686-w64-mingw32 (32 bit).
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=/RosBE64 --host=i686-w64-mingw32 --build=i686-w64-mingw32 --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
Enter 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-pkgversion="RosBE-Windows" --enable-languages=c,c++ --enable-checking=release --disable-win32-registry --disable-shared --disable-nls --disable-werror --disable-multilib --with-sysroot=/RosBE64 --enable-version-specific-runtime-libs --with-host-libstdcxx="-lstdc++ -lsupc++"
32 bit:
../../src/gcc/configure --prefix=/RosBE64 --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=/RosBE64 --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:/RosBE64/bin"
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/x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --build=i686-w64-mingw32 --with-sysroot=/RosBE64
32 bit:
../../src/mingw-w64/mingw-w64-crt/configure --prefix=/RosBE64/i686-w64-mingw32 --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")
