I don't know anything about making a combined source tree, but I can tell you what I do to try out cross toolchains (I am trying to build two, currently, one of which is a canadian cross. They all involve Kai's work on x86_64-pc-mingw32). Note that I may be doing things totally wrong (in which case, someone please tell me!) But this works for me... your mileage may vary. First, I create some staging area for a new root: mkdir /myroot, mkdir /tmp/myroot, mkdir /opt/root, etc etc. Pick whatever works for you. I'll do /me so I can type less :) I use this area for everything. Now, all the tools support the use of with-sysroot and --prefix. I set both to this newly created path, allowing me to put everything in a safe place using a system with pre-existing stuff so I don't accidently break anything serious (I'm VERY talented at destroying systems unknowingly.) So try to follow these steps: mkdir /me && cd /me && mkdir build && cd build && mkdir binutils gcc && cd binutils cvs -Qz 9 -d :pserver:anoncvs@xxxxxxxxxxxxxx:/cvs/src co binutils mkdir build && cd build ../src/configure --with-sysroot=/me --prefix=/me --disable-nls --target=x86_64-pc-mingw32 > /dev/null make > /dev/null make install > /dev/null cd ../../gcc svn -q checkout svn://gcc.gnu.org/svn/gcc/trunk gcc-latest mkdir build.core && cd build.core ../gcc-latest/configure --with-sysroot=/me --prefix=/me --disable-nls --enable-languages=c --target=x86_64-pc-mingw32 > /dev/null make all-gcc > /dev/null make install-gcc > /dev/null Now at this point you have to build some libraries. I was using Kai's libraries, as glibc doesn't support my target yet. Do what you will there. When you are done and have installed them in /me, do this: cd /me/build/gcc mkdir build.full && cd build.full ../gcc-latest/configure --with-sysroot=/me --prefix=/me --disable-nls --enable-languages=c,c++ --target=x86_64-pc-mingw32 > /dev/null make > /dev/null make install > /dev/null Select all the languages you want. I chose c and c++. This should install a full compiler in your root. Now just add /me/bin to your path, and the x86_64-pc-mingw32-gcc (or whatever target you build) executable will be available whenever you try to cross compile a program.
