Redirecting compiler output

[lrtaylor@micron.com]

Try 

g77 code.f >& report.txt

or

g77 code.f > report.txt 2>&1

The ">" alone only causes stdout to be redirected to a file.  ">&" in some shells causes everything to get redirected.  In other shells "2>&1" tells the shell to redirect stderr to the same location as stdout.

Cheers,
Lyle

I cannot get g77 and gcc to redirect compiler messages to a text file.
The line

g77 code.f > report.txt

only creates a file report.txt of zero lenght and any error or warning 
messages from the compiler only scroll by on the screen. I get the same 
behaviour working in KDE graphic mode and in plain text mode (SuSE Linux 
8.1) with various versions of gcc. I am using 3.3.2 now.
And the same happens with gcc 3.2.2 running under MinGW/Windows98 so I 
doubt it is an OS problem.

I have not found any clue in the gcc manuals.

Best regards
