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

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.

finally directory layout:

    x86_64-w64-mingw32-c++, x86_64-w64-mingw32-gcc,....
lib
   gcc

    bin
    include
    lib

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 1
gmp-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

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

mypath=/works/tools/compiler/mingw32/x86_64-w64-mingw32

../configure --with-sysroot=$mypath --prefix=$mypath --host=x86_64-w64-mingw32 --enable-multilib --enable-lib32 --enable-lib64 --enable-experimental --enable-targets=x86_64-w64-mingw32,i686-w64-mingw32

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
https://sourceware.org/pthreads-win32/
export PATH=/works/tools/compiler/mingw32/bin:$PATH

MINGW32_PATH=/works/tools/compiler/mingw32
make clean GC-static CROSS=x86_64-w64-mingw32- CFLAGS=‘-I. -I$(MINGW32_PATH)/x86_64-w64-mingw32/include --sysroot=$(MINGW32_PATH)/x86_64-w64-mingw32‘  -f GNUmakefile PTW32_FLAGS="-DPTW32_STATIC_LIB"
After sucess，Install it：
cp -f pthread.h $(MINGW32_PATH)/x86_64-w64-mingw32/include
cp -f sched.h $(MINGW32_PATH)/x86_64-w64-mingw32/include
cp -f semaphore.h $(MINGW32_PATH)/x86_64-w64-mingw32/include
cp -f config.h $(MINGW32_PATH)/x86_64-w64-mingw32/include/pthread_config.h
cp -f libpthread.a $(MINGW32_PATH)/x86_64-w64-mingw32/lib
GNUmakefile中，ARTI=‘-m32‘ stand for build x32,so you‘ll must build it again for x32,then:
cp -f libthread.a $(MINGW32_PATH)/x86_64-w64-mingw32/lib32

modify $(MINGW32_PATH)/x86_64-w64-mingw32/include/pthread.h:
#if defined(HAVE_PTW32_CONFIG_H)
#include "config.h"
#endif /* HAVE_PTW32_CONFIG_H */
change to:
//#if defined(HAVE_PTW32_CONFIG_H)
#include "pthread_config.h"
//#endif /* HAVE_PTW32_CONFIG_H */

8.Build libgcc last!
cd /run/media/lixing/6T_20181101_3/mingw32_20190521_src/gcc_build
make -j4 && make install
