My guess is your install prefix isn't added to your $PATH. If you
didn't specify a --prefix=... to the toplevwl configure, gcc will
install to /usr/local and if this is the case you may need to:

$ PATH="$PATH:/usr/local"

And try again.

Yes, It was a problem of PATH values, I added /usr/local to the path value and 
it compiled now but I get error while linking :

[root@is010178 python_files]# /export/home/charfi/Bureau/buildpython/gcc/gccpy

it doesn't matter, what I need is to look at the gimple and generic code 
generated using python fe: 

although generic form is not generated explicitly : can not find t.generic when 
I type -fdump-tree-all :( :(
I found only t.py.004t.gimple which is gimple representation of the input file.
Is there any way to generate the generic form (sth like t.py.003t.generic ;)

thank you ;)  

Asma
