installing gcc on a pc running Redhat Linux6.2

installing gcc on a pc running Redhat Linux6.2

[Michael Fothergill]

I ran the config.guess and the output was

i686-pc-linux-gnu.

What does this mean.

When I ran install the machine did a few things and seemed to run out of 
steam

The end of the installation went as follows:

cp: cannot create regular file `/usr/local/bin/#inst.21741#': Permission 
denied
chmod: /usr/local/bin/g++: No such file or directory
ln: /usr/local/bin/g++: No such file or directory
cp: cannot create regular file `/usr/local/bin/#inst.21775#': Permission 
denied
chmod: /usr/local/bin/c++filt: No such file or directory

esac

Do you think GCC installed correctly?  The configure and the build seemed to 
work OK.


How do I actually run the compiler (e.g. the Fortran compiler)
Whereabout in the documentation are the instructions?

If I compiled the ordinary GCC (which I did) (v.2.95.2 or whatever it is) do 
I get C++ C JAVA and Fortran.

How do I test it?

How do I test it myself?

It means that you are running on a 686 machine that is running some form
of linux.

Definitely not.

You do not have write permission into /usr/local.  You need to do the
final install as root unless you specify a prefix where you can write.

Put the compiler in your path.  Run it :)  The documentation covers the
options available.  A simple command line would be:

gcc hello.c -o hello

and will produce an output (-o) executable called hello from the input
(c) file hello.c.

make check-gcc in the build directory.  But I think you just want to
make sure that it will work, in that case just compile something as
above.
