RE: porting to interix

Hi Jay,

Yes you're correct. I'm running SFU and SUA and would like to get gcc to be
supported on those platforms. The gcc compiler ports that MS provides for
interix only include C/C++ so it doesn't include libffi.
I've so far adapted the GCC4.4.0 tarball on interix to bootstrap C and C++
only but I also want the Fortran compiler i.e. libffi is a prerequisite.

I seem to have read on some newsgroup that the error messages I encounter
when trying to build libffi has to do with the binutils assembler being
invoked during the build phase: it must be ELF compatible or so. If anyone
has a clue that would be great.

Many thanks,

Rob

p.s. Building python doesn't require libffi but just a C compiler AFAIK.

Robert, you are aware that libffi isn't used by C or C++?

It is for Objective-c or Java or Fortran or Ada, or something, probably
Java.

Do you want more than C and C++?

 

I would suggest:

 

ftp://mirrors.kernel.org/gnu/gcc/gcc-4.4.0/gcc-core-4.4.0.tar.gz

 The C compiler, and some other.

 

ftp://mirrors.kernel.org/gnu/gcc/gcc-4.4.0/gcc-g++-4.4.0.tar.gz

 add C++ if you want.

 

And get the 4.2 stuff.

That includes a patched gcc 4.2.

Compare with the mainline 4.2.

Apply patches to mainline 4.4.

 

Lobby Microsoft to submit its patches.

 

Also, if you have never built gcc before, I would suggest first building it
on a better supported platform, such as Linux or Cygwin.

 

That all said, since this is libffi-discuss :), it would be nice to have a
port.

  The more the better. :)

I wonder what the deal is with Python. I ran into a problem on hppa64-hpux
building Python, because libffi isn't supported there.

So I wonder how anyone ported Python to SFU, I know there is a download of
it, I haven't looked at it yet.
