Hi,

If I compile a project the -gh (Heaptrc unit), how to I capture the output generated when I quite the application to a file?

I tried the normal: $./text > out.log

But that doesn't work... the out.log is empty.

Regards,

./something >& out.log

however units like crt might make this not possible. The exact solution for that differs with application.

RTFM for the log=... use
http://www.freepascal.org/docs-html/rtl/heaptrc/environment.html

if no filename is given, it outputs to stderr and not stdout.

You can also set an environment variable.

Thanks Darius and Vincent. I'm new to heaptrc and just tried it out. For some reason I didn't even think to look for docs... My bad.

Maybe you use another shell than Marco (that's [t]csh), you could look at the man page for your in the part "output redirection" or similar.

For sh and maybe bash getting stdout and stderr in the file

./something 2>&1 out.log

should do. I didnt test, but getting stderr only may work like this:

./something 2> out.log

HTH,
Marc

I use bash and the above doesn't work... Henry's example of ./something > log.txt 2>&1 works though.

That doesn't work, it would only for piping:

./stdfile 2>&1 | cat > out.log

But the rest was okay. Henry got it right however ...
