PS:  I have gcc libraries 2.7.2.2, and gnat seems to install in 2.7.2.1.
Could this be the problem?  How would I solve it?

Install problems GNAT/CC/Linux

[John M. Greer]

I'm having some serious problems installing GNAT on my Linux system 
(recent kernel & libs.)

When I install gnat v.10, and try to compile an Ada program, I get an 
error that says (roughly):  
gcc -c driver.adb
gcc: driver.adb: linker input file unused since linking not done


When I reinstall gcc (via setup CD-ROM), I get the following error: 

gcc: installation problem, cannot exec `cc1plus': No such file or directory

What is going on?  Help!!

In order to support GNAT, the gcc front-end should be recompiled (i.e. you
should recompile gcc); the problem is that the version you installed from
the CD-ROM wasn't compiled with GNAT support included.

NOTE: Many GNAT binary distributions include a replacement for your gcc (often
called xgcc), that is installed over gcc and add support for GNAT (NOTE: this
way you can lose support for other languages - for instance, Obj-C or
Fortran 77 - if the gcc replacement wasn't compiled with support for those
languages enabled).

This is a typical installation problem (you are clearly using the wrong
vesion of gcc, one that does not know about Ada). For this and similar
problems, I recommend that you subscribe to chat@gnat.com by sending a
subscribe message to chat-request@gnat.com. You may be able to find someone
who can provide informal help there. Generaly chat@gnat.com will be a much
more effective place for discussion of GNAT problems that CLA, since there
are many GNAT users who participate in chat who do not bother to read CLA.
