[GCC front end] trying to install sample_fe but fail in make

[charfi asma]

Hi Philip,

I red your 10 doc pages 
http://code.redbrain.co.uk/cgit.cgi/gcc-dev/tree/gcc/doc/languages.texi?h=documentation
 it was helpful for me to understand  the role of lexer.l and parser.y in the 
python fe.
what I try to do is to compile your fe. I thought that I can add the python fe 
to gcc, write file.py and compile this file using gpy1.
Normally, we can write code in python and gcc will compile and execute this code 
if the python fe is added to gcc directory, configured and installed.

I tried to follow your instructions, but it fails in git merge python
here is the error:

[charfi@is010178 gcc-dev]$ git merge python
fatal: 'python' does not point to a commit

[charfi@is010178 gcc-dev]$ git merge documentation
fatal: 'documentation' does not point to a commit

any idea ?

hope that you did not spell the branch name
wrong as usual when dealing with documentation ;)

thanks 

Asma

Hey

I am not quite sure what your trying to achieve at the moment if you
copy the python front-end folder into a base gcc the resulting
compiler won't work since you also need libgpython at the toplevel the
runtime library which the generated code needs linked against. So i
suggest follow these instructions:

$ git clone git://crules.org/git/gcc-dev.git
$ git branch test
$ git checkout test
$ git merge python
$ git merge documentation

Then try and compile... make sure you can compile gcc normaly from a
tarball or something so we can be sure there isn't some error on our
side with libmpc checks.

You should now have gcalc and gccpy, though i reckon gcalc may fail
compilation since the langhooks have have changed slightly, but i'll
check and fix it soon, i took a few days off there since friday. Back
hacking now though :)

Hope this helps, sorry for the late reply.
