gfortran and g77 on lion

Hi

I got xcode 4.3.2 and put it in applications and am running OS X 10.7.3. I installed g77 and gfortran from sourceforge.net. But when I am compiling a simple test program I get the following error with gfortran.

gfortran: error trying to exec 'as': execvp: No such file or directory

I searched, but there is no as on my system in /usr/local/bin. I am new to Mac so don't know much about the functioning of xcode. Please suggest what to do.

Thanks, Smriti

I don't know the problem, but did you install the extra tools. Xcode now installs in the Applications folder and there is an extra, I think command line, toolset to install. Check out the downloads section where you found Xcode 4.3 for that.

Search for the word command in the New Features in Xcode 4.3 document.

Thanks xstep! That was indeed the problem.. gfortran works fine now.
