2009/9/17 Marco van de Voort :
The -V and -P options are nearly as old as the buildfaq. Any non ancient
version should have them. They should be documented afaik, and are covered
in the buildfaq.
All good an well, but the buildfaq is not an available option to download from the freepascal.org website.
http://www.freepascal.org/docs.var
Not to mention that -V is not listed in the "fpc -h" output as shown below. I tried FPC 2.2.5 and FPC 2.3.1 - both latest revisions available.
Also the help for -T<x> as listed below seems to be very different to what you are talking about. So no, it doesn't seem to be that obvious as you suggested. :-(

That is a ppc386 parameter. I'm talking about fpc parameters.
I typed the following to get the above output:
$ fpc -h
What's the difference between 'fpc' and 'ppcXXX'...? I assumed 'fpc' it's some symlink or alias to your platform's real pppXXX binary.
