Hello

Could you please direct me on how to change gcc so that it will translate
c/c++ files to an assembly language to a new instruction set that I am
building?

Thank you in advance
Amnon

Changing gcc

[djfm]

Hi!
I'm new to Linux , I am under mandrake 8.2 , and I wanted to upgrade my
gcc native compiler (2.96) to the last 3.2.2 , I downloaded it on
gcc.gnu.org , and followed the compilation instructions. Or I may
suppose to have done so. I've made a "make bootstrap" , all seem to have
worked correctly , now I have the binaries and libraries installed in
usr/local/ but they have not self-replaced the old ones. 
I have prefixes before app and folder names , such as
"i686-pc-linux-gnu-gcc" ...
I dunno what to do , what file to rename nor where to put them.
Please answer *simply* , Im absolutly new to linux. 
Dont forget to explain the stupid etaps that I'm sure I would fail in.
Thx a lot by advance to all.

PS: I dunno whether I'm wrinting to a newsgroup or to an email. I'm not
used to  it , I apologize.
Anyway please answer by mail.
And sorry for my bad english.

Thx again.

Leave the old files where they are, and just change your PATH
environment variable so that /usr/local/bin (or whereever you installed
the new gcc) is included at the start.

E.g. if you are using bash, you can add the following line to your
~/.bash_profile file:

	PATH=/usr/local/bin:$PATH
