> please provide the step-by-step instruction you used.
1. Extract binutils gcc mingw-w64 files to any where
Extract gmp mpfr mpc isl to gcc source directory
note: please make sure no subdirectories are included under
gcc-x.x.x/{gmp,mpfr,mpc,isl}.
these file can be found here
http://ftp.gnu.org/gnu/binutils/
http://ftp.gnu.org/gnu/gcc/
https://sourceforge.net/projects/mingw-w64/files/mingw-w64/mingw-w64-release/
https://gmplib.org/#DOWNLOAD
https://www.mpfr.org/mpfr-current/#download
https://www.multiprecision.org/mpc/download.html
https://libisl.sourceforge.io/
2. Clone the windows default manifest
(git://cygwin.com/git/cygwin-apps/windows-default-manifest.git)
3. These instructions are used to build cross toolchain and install to /mingw
(can be changed to other directory).
note: use "make -j$(nproc)" instead "make" to use more CPU cores.
1) Set PREFIX and PATH variables
export PREFIX=/mingw
export PATH=$PATH:$PREFIX/bin
note: if you are not root, please run "sudo mkdir /mingw && sudo chmod 777
/mingw"
2) chdir to gcc source directory and run "sed -i
's/${prefix}\/mingw\//${prefix}\//g' configure"

3) Build binutils
../binutils-2.40/configure --disable-nls --disable-rpath --enable-64-bit-bfd
--enable-deterministic-archives --enable-install-libiberty
--target=x86_64-w64-mingw32 --prefix=$PREFIX
make && make install-strip
4) Install mingw-w64 headers
../mingw-w64-v10.0.0/mingw-w64-headers/configure --host=x86_64-w64-mingw32
--prefix=$PREFIX/x86_64-w64-mingw32
make && make install -j16
5) Build GCC core compiler
../gcc-12.2.0/configure --disable-multilib --disable-nls --disable-rpath
--disable-symvers --enable-languages=c,c++,lto --enable-mingw-wildcard
--enable-threads=posix --enable-libgomp --disable-libstdcxx-verbose
--enable-fully-dynamic-string --target=x86_64-w64-mingw32 --prefix=$PREFIX
make all-gcc && make install-strip-gcc
6) Build mingw-w64
../mingw-w64-v10.0.0/configure --enable-experimental --disable-lib32
--host=x86_64-w64-mingw32 --prefix=$PREFIX/x86_64-w64-mingw32
make && make install-strip
7) Build winpthreads (pthread support for windows)
../mingw-w64-v10.0.0/mingw-w64-libraries/winpthreads/configure
--host=x86_64-w64-mingw32 --prefix=$PREFIX/x86_64-w64-mingw32
8) Build windows default manifest
x86_64-w64-mingw32-windres -F pe-x86-64
./windows-default-manifest/default-manifest.rc -o
$PREFIX/x86_64-w64-mingw32/lib/default-manifest.o
note: this has the same effect as the following command
../windows-default-manifest/configure --host=x86_64-w64-mingw32
--prefix=$PREFIX/x86_64-w64-mingw32
make && make install
9) Build GCC compiler
chdir to build gcc directory and run "make && make install-strip"
4.Now we have a mingw-w64 cross toolchain (without zstd libiconv support)
So we can build canadian toolchain easily
1) Build binutils
../binutils-2.40/configure --disable-nls --disable-rpath --enable-64-bit-bfd
--enable-deterministic-archives --enable-install-libiberty
--host=x86_64-w64-mingw32 --prefix=$PREFIX
2) Build GCC
../gcc-12.2.0/configure --disable-multilib --disable-nls --disable-rpath
--disable-symvers --disable-win32-registry --enable-languages=c,c++,lto
--enable-mingw-wildcard --enable-threads=posix --enable-libgomp
--disable-libstdcxx-verbose --enable-fully-dynamic-string
--host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --prefix=$PREFIX
3) Build mingw-w64, winpthreads and windows default manifest
../mingw-w64-v10.0.0/configure --enable-experimental --disable-lib32
--host=x86_64-w64-mingw32 --prefix=$PREFIX
../mingw-w64-v10.0.0/mingw-w64-libraries/winpthreads/configure
--host=x86_64-w64-mingw32 --prefix=$PREFIX
x86_64-w64-mingw32-windres -F pe-x86-64
./windows-default-manifest/default-manifest.rc -o
install_dir/lib/default-manifest.o
