Thread: RH 7.2 buit-in C compiler?

Does Linux Red Hat 7.2 have a built in C compiler? If so, how do I access it?
Thanks,
Bud

Try whereis gcc. If it returns /usr/bin/gcc, it's installed. Otherwise search your Red Hat cdroms; mkdir /cdrom; mount -t cd9660 /dev/cdrom /cdrom && find /cdrom -name "*gcc*"

Code:

cat > foo.c
#include <stdio.h>

int main()
{
  puts( "hello world!" );
  return 0;
}^D
gcc foo.c -o foo && ./foo

you should do if you installed it on setup.

to test you do type

which gcc

this will tell you if you have it, if you do it'll tell where it is installed.

To use it you have to be in konsole, when you are there you can use it from any directory. Simply type

gcc -Wall filename -o program-Name

"-Wall" turns all warnings on
"-o program-Name" program-Name becomes the executable
"filename" can be a list of C files

if you don't use -o option, then it compiles the program to the default "a.out"

to run the program type:
./program

the dot-slash specifies the program is in the current directory

hope this helps

redhat does bundle gcc with it. as a matter of fact, it changed gcc 2.95.3 and renamed it 2.96RH.

that may not always work. on my emacs the compiler is not pre-determined. just run "gcc -v" at the command prompt and it should tell you something about gcc (or the fact that it doesn't exist.)
