    Compile gcc 4.9.4 + latest-Mingw-w64 on linux 2019.05

    1.At first, build Binutils-2.292.Compile mingw-w64-headers of mingw-w64-mingw-w64_master3.Create soft-link4.Compile gcc4.9.4, Gcc, pass 1gmp-6.1.0.tar.gz5. mingw-w64-crt6. Build libgcc7. pthreads8. Build libgcc last!

    Compile gcc4.9.4 + Latest-Mingw-w64 under Linux, build Cross-compile-toolchain , to generate software which can run on windows xp and xp+ x32/x64.

    We generate all static compile.

    Reference: /run/media/lixing/6T_20181101_3/mingw32_20190521_src/mingw-w64-mingw-w64_master/mingw-w64-doc/howto-build/mingw-w64-howto-build.txt

    finally directory layout:

    /works/tools/compiler/mingw32/ bin x86_64-w64-mingw32-c++, x86_64-w64-mingw32-gcc,… lib gcc libexec gcc share x86_64-w64-mingw32 bin include lib lib32 mingw(ln -s x86_64-w64-mingw32 mingw ，it’s x86_64-w64-mingw32’s soft-link)

    1.At first, build Binutils-2.29

    cd /run/media/lixing/6T_20181101_3/mingw32_20190521_src/binutils-2.29 mkdir build cd build …/configure --prefix=/works/tools/compiler/mingw32 --with-sysroot=/works/tools/compiler/mingw32 --enable-gold --enable-ld --enable-lto --target=x86_64-w64-mingw32 --enable-targets=x86_64-w64-mingw32,i686-w64-mingw32 make make install

    2.Compile mingw-w64-headers of mingw-w64-mingw-w64_master

    cd /run/media/lixing/6T_20181101_3/mingw32_20190521_src/mingw-w64-mingw-w64_master/mingw-w64-headers mkdir build cd build …/configure --host=x86_64-w64-mingw32 --prefix=/works/tools/compiler/mingw32/x86_64-w64-mingw32 make make install

    3.Create soft-link

    cd /works/tools/compiler/mingw32 ln -s x86_64-w64-mingw32 mingw

    4.Compile gcc4.9.4, Gcc, pass 1gmp-6.1.0.tar.gz

    mpc-1.0.2.tar.gz mpfr-3.1.4.tar.gz unzip them to path gcc4.9.4 ，corresponding to decompressed folder name is:gmp,mpc,mpfr,so that gcc will found them when gcc compiling. cd /run/media/lixing/6T_20181101_3/mingw32_20190521_src/gcc4.9.4

    we need build gcc outside src directory. cd … mkdir gcc_build cd gcc_build

    Reference： /run/media/lixing/6T_20181101_3/mingw32_20190521_src/gcc4.9.4/INSTALL/configure.html

    make all-gcc -j4 make install-gcc

    5. mingw-w64-crt

    cd /run/media/lixing/6T_20181101_3/mingw32_20190521_src/mingw-w64-mingw-w64_master export PATH=/works/tools/compiler/mingw32/bin:$PATH mkdir build cd build

    make -j4 make install

    6. Build libgcc

    cd /run/media/lixing/6T_20181101_3/mingw32_20190521_src/gcc_build “make all-target-libgcc”, then “make install-target-libgcc”.

    7. pthreads

    above link may be invalid, so I introduce it: /run/media/lixing/6T_20181101_3/mingw32_20190521_src/pthreads/GNUmakefile: DEVROOT = /works/tools/compiler/mingw32/x86_64-w64-mingw32

    DLLDEST = $(DEVROOT)/dll LIBDEST = $(DEVROOT)/lib ARTI=-m32

    CC = $(CROSS)gcc $(ARTI) CXX = $(CROSS)g++ $(ARTI)

    ifeq (’$(ARTI)’,’-m32’) ARFLAGS = --target=pe-i386 DLLTOOL = $(CROSS)dlltool -m i386 RC = $(CROSS)windres -F pe-i386 else ARFLAGS = --target=pe-x86-64 DLLTOOL = $(CROSS)dlltool RC = $(CROSS)windres endif

    AR = $(CROSS)ar $(ARFLAGS) RANLIB = $(CROSS)ranlib $(ARFLAGS)

    OPT = $(CLEANUP) -O3 # -finline-functions -findirect-inlining XOPT = RCFLAGS = --include-dir=. -I/works/tools/compiler/mingw32/include

    CFLAGS = $(OPT) $(XOPT) -I. -I/works/tools/compiler/mingw32/include --sysroot=/works/tools/compiler/mingw32 -DHAVE_PTW32_CONFIG_H -Wall

    8. Build libgcc last!

    cd /run/media/lixing/6T_20181101_3/mingw32_20190521_src/gcc_build make -j4 && make install

    Now, you can generate x32 exe for windows: /works/tools/compiler/mingw32/bin/x86_64-w64-mingw32-gcc -m32 helloworld.cxx -o main.exe
