I agree that the best option would be to use the -V and -P options of
fpc.
But, for this, it would be best if fpc can list the available versions
and
architectures/cross-compilers.
Assuming that list of supported FPC installations should be configurable
by the user in Lazarus settings, listing of versions wouldn't be
necessary
(it would be incomplete anyway in many cases). I see no use for -V in
this
use case either (due to differences between global and local
installations
and also installations in non-standard places). I believe that -Xp
should
cover everything needed (at least as long as that parameter is supported
by the installed FPC version; if not, invoking fpc with a modified PATH
would be my suggested solution).
I think you are wrong.
-Xp is there for the case you have a special setup.
-V is there for standard installations, so you don't need to know the
paths.
I think it is by far preferable to use the latter.
If you're not going to use/encourage it, you'd better remove it
altogether.
I certainly don't need to be right here ;-)
No, sorry, I didn't phrase that correctly.
My phrasing was a bit crude, I should have written that I don't share your point
of view here. Crude phrasing happens if you answer too quickly :(
but my thought was that if
Lazarus wanted to cater for both standard installations (releases) and
non-standard ones (allowing users to configure them inside Lazarus rather
than expecting that Lazarus should detect them automatically, of course)
as suggested by Mattias in his earlier e-mail, using -Xp would be a more
generic solution.
That obviously does not imply that -V shouldn't be used with fpc for other
use cases, it's just that it may not fit the Lazarus need completely (as
far as I understood Mattias correctly, of course).
Well, generally speaking I think that -Xp should not be there to begin with.
Starting from there, recommending its use is, obviously, even worse practice :)
But it's up to the lazarus team to see what solution they prefer.
I will limit myself to documenting the various possibilities :-)
Michael.
