Do I have gcc & gfortran installed?

Hi there. I have tried to install gcc and gfortran and it seems I succeeded although when I try to use search window I get negative results. Please, take a look at the image I posted. I used two commands: man gcc and gcc. When I typed gcc it gave me an error saying that no input file was provided which is true. The same happened when I typed gfortran.

Does it mean that I have both packages installed?

Thanks, - Alex

From your screenshot, it looks like they are installed.

To be sure, type the following, which will tell you the version numbers of gcc and gfortran:

Code:

gcc -v

gfortran -v

If you get something that says a bunch of stuff that tells you the version, target, etc. you have them installed. If you get "command not found" they are not installed.

Good luck!

bcwagne, thank you. This is what I got when I typed the first line:

Quote:

gcc -v

You can see it in the snapshot. So much output came out. It surprised me. and the next thumbnail will be about gfortran. Thanks for the idea. So, do you think everything is OK? - Alex

Hi Alex,

I don't know about gfortran but I installed gcc on my fedora box and used this to compile an existing c file. I would say you are on the right track :)

Code:

[tim@beiderbeck ~]$ gcc -v

gfortran looks good as well. Unfortunately I don't have any fortran files kicking around to try with but this is the response I received.

Code:

[tim@beiderbeck ~]$ gfortran -v
