I am using Fedora Core 5 which contains a gcc of version 4.1.

I had install gcc-3.4.4 yesterday. But when I ran the `configure' script in extracted tar.gz ball, I haven't specified the --prefix argument. Then when I executed "make" and "make install", the gcc-3.4.4 was installed into /usr/local/. Of course, in subdirectories of /usr/local/, such as /usr/local/bin, /usr/local/lib, etc.

But I wanna uninstall it now.
I removed all files that created to /usr/local/ by "make install", including /usr/local/bin/gcc

Then I typed gcc, the shell said, "/usr/local/bin/gcc no such file". And when I typed ``gcc -v", it said the version is 3.4.4 which doesn't exist now- it has been removed by me.
Then I typed ``which gcc", shell said /usr/bin/gcc.

In my mind, due to my PATH environment variable setting, if a file named gcc can't be found in /usr/local/bin, the system should search in /usr/bin .
But obviously, it doesn't work like this. Only the ``which gcc" command works in that order. It should be some other configuration file is working. I have checked the /etc/profile and ~/.bachrc, there is no setting will effect this.

Which file does linux use to record the gcc location?


my PATH env. variable:
declare -x PATH="/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/usr/local/share/texmf/bin:/root/bin:/usr/local/share/texmf/bin:/usr/local/share/texmf/bin:/usr/local/share/texmf/bin:/usr/local/share/texmf/bin"

Try entering the command
and see if that helps. Basically, it will look in /usr/bin first. If this works, add the above line to .bashrc, and add "export $PATH" at the end of .bashrc.

If the above doesn't help, try "whereis gcc" or "locate gcc" to find out where gcc is installed, and make sure that it is in your $PATH.


I hope this helps
--Ian

it should be no further configuration file? I just need to check the environment varibales?
I am afraid that /usr/local/bin/gcc related with other include or lib diretories.



now the result is:
[root@silver ~]# whereis gcc

I modified your title slightly since rather then deleting your post as you had originally requested.

John

I am not sure what you are asking. Are you asking, how do you know which version of gcc a program you plan to compile needs? Or, are you simply trying to find out which version a particular program was compiled with? Do you just want to know what versions exist on your computer?
