well if you do infact say its installed, then try to compile the following code :
(also double check if it installed correctly by typing
gcc -v)
if you get command not found, then it did not obviously install correctly ...
Code:
#include <stdio.h>
int main( void )
{
printf("\nHello, world!\n");
return 0;
}
save the file as test.c and then type
gcc test.c -o test
one more thing to check is to see if you have an executable called
gcc in /usr/bin ... well its actually a symlink to the compiler ...
if that does not exist then symlink it to the compiler (for example mine is called gcc-3.2.3) so if i were to make a symlink i would type :
ln -s gcc-3.2.3 gcc
(that is if i was
in /usr/bin, otherwise type full commands)
yours will probably be called gcc-3.0.4 since you say thats the version ...
and to see right away what you have going on you can type something like :
which gcc
which should output /usr/bin/gcc
or just use ls by typing :
ls -alc /usr/bin/gcc*
i am just starting to ramble on here, so hopefully this leads you in the right direction ..
