I recently download gcc-2.6.3.bin.tar.gz and executed the commands:

cd /
gzip -dc gcc-2.6.3.bin.tar.gz | tar xvvf -

and it seemed to work ok, with the exception that now when I type `gcc'
at the command line, I get "gcc: command not found". If I type
`which gcc' it says /usr/bin/gcc, and gcc is mod 755, as it should be.

is going on here? Suddenly, I can't compile anything!

Please help! Thanks in advance.

Not sure what shell you are using, but some shells "cache" the paths for
executables in your path. When you change such a file you have to do a
"rehash" command (tcsh) or equivalent to update the shell's internal
database.

I've just had *exactly* the same experience! I tried logging out
then logging in again and all sorts of things... and still get
the "command not found" error. Weird.

I had only just installed 2.5.8 from the slackware distribution,
and for some reason it didn't work (I couldn't compile anything,
not even a simple "hello world"). So I tried for 2.6.3 and this
happens. Now I'm faced with deleting all the development stuff
from my hard drive and starting again fresh. :-(

Is there some way to install software in a manner that isn't so
brutal and crude as a gzip -dc | tar xvf - from the root
directory (or wherever)? So that it gets recorded nicely into
the /var/adm/* subdirs etc. Is there something magical about
.lsm files that allows this to happen?

Cheers
Tony
