gcc 7.1.0

gcc 7.1.0

[Zane Asher Post]

Hi. I'm trying to compile a cross compiler to build my OS. I'm trying to
build on Windows using MSYS2. I'm having a couple of issues, though. First,
when it gets to s-selftest in gcc-build/gcc/Makefile, it stops with this
error:

CreateProcess: not a directory or file

It works when I copy cc1.exe into a folder that is in my PATH variable. I'm
afraid that this will mess with my C compiler and the one that is built.
Second, when libgcc is being configured, I get this error:

Cannot compute the suffix of object files

How do I fix these errors?
From, Zane Post
P.S. My configure flags for gcc are:

../gcc-7.1.0/configure --build="aarch64-w64-mingw32" --target="i686-elf"
--prefix="/c/compiled/gcc" --disable-nls --without headers
--enable-languages=c,c++ --without-isl --disable-fixincludes

I too have had fun with building GCC on Windows using MSYS2.  Fortunately
for me, the mingw-w64 development team has been very helpful.

I know of at least one of the mingw-w64 developers chimes in on the binutils
list, perhaps there are some of them on this list, too.

I'd start with this github repo which provides patches for building GCC within
an MSYS2 environment:

https://github.com/msys2/MINGW-packages

There are patches and pacman build scripts (pay attention to the
scripts, they do
some magic aside from applying patches).  There is stuff there for arm cross
compilers.  But beware, these patches may no longer apply for GCC 7.0 as the
mingw-w64 folks keep pretty current with packages they deliver.

Hope this helps,

Tom
