Question about Linux Builder Requirements

thanks for your list, perhaps I can help - without having a "running
Revolution application" on Linux yet - getting some issues solved:

That may be related to Windows and MacOS using a different windowing
system than X, which is "client-server". I guess these issues would have
to be solved on Revolution's site, but I can imagine it could be quite

Unix (Linux) "loves" Spaces, but they have to be backslash-escaped if
you use shell tools. I don't know how Revolution accesses files, if it
uses system calls like "fopen" etc, spaces definately would be no
problem. Perhaps there is a bug inside the filehandling in Revolution
leading to a wrong escaping on Linux but the correct escaping on Mac and
Windows. Information about how file access is being done inside the
engine would help here.

I would expect the working directory to be the "Default Folder". WD
depends on what is set as WD inside the shell session you are in. I can
only guess here (I currently do not have a working Revolution app under
Linux), but you could try doing a "cd your-default-directory" during
startup of your stack, I would expect this to lead to the needed behaviour.
> - Sockets work fine except for broadcasting (not related to Revolution).
Broadcasting (always) depends on the network settings/network hardware
setup. Broadcast has to be handled with care as it can lead to routing
problems. One could do a tracking about networking setup being done by
Revolution - or such information could be given by RunRev.
> - No icon support for your stand-alone other than what Gnome or KDE
This has to be resolved by RunRev. Windowing systems like Gnome and KDE
do offer "personal" icons, perhaps there is a bug in the app builder?
> - Fonts are very minimal, and there doesn't seem to be support for TrueType.
This surely isn't a problem of Revolution/RunRev: Support for TrueType
is offered through various libraries, but isn't a "native feature" of
most windowing systems. It is possible that calls for font rendering
inside the Revolution engine is not up-to-date but I would not call this
a bug. In ancient times one always had to "render" the font required to
native format ...

No doubt about that. I wish I could actually create RUNNING applications ;-)
