For no real reason other than interest, I'm trying to run a major app
on Ubuntu.

So far:
 1. dbsys works fine
 2. a simple app with one table and a dbgrid works fine
 3. my major application will not start.

Anyone got experience with this that would like to comment on
their success/failure accomplishing running an application
on Ubuntu?

Short of breaking the application into many sub pieces in order
to find what stops it running, I'm at a loss as to how to
debug the problem.  However, as I said before, it's just out
of interest rather than a real issue.

Ignoring the fact you're in the wrong newsgroups I'm surprised anything works. Are you running under WINE or....

JonD,

I've experimented with Wine in the past and got everything working OK
(mostly on CentOS but tried Ubunutu as well).

As to the app it 's possibly due to 3rd party components that use
something that is not well implemented in Wine - one of my apps had TAPI
dependency and that never worked so had to do a conditional compile and
generate an exe without it.

Other things i would look at that might cause problems : interaction
with hardware components (serial port as i recall was ok but not sure of
usb, printers, etc) or use things like skins or something else that uses
some lower lever graphics calls that Wine again might not support.

Good luck and pelase update back if you do find out what caused it.

Hi Roy and Raul.

Roy: actually wasn't sure what groups were left for 'discussion' so just
    picked this one.

Raul:
Found the issue with a missing fontsub.dll that must be a standard file
for all windows installations as I certainly don't distribute it with my
application.

Once I copied the file into the crossover bottle, the application worked
perfectly... I'm amazed at how it works.

I was only joking. You'll have to post some screenshots.

Well the screen shots appear just the same as on Windows 7.
The only issue that I've come across... I've used
  Ctrl-Alt-Del-F9 to reveal an infrequently used
menu item and Ubuntu uses that to control sessions.
Not a problem to change in the application if I ever chose to
deploy to Ubuntu.

I had one request to deploy to a Mac and CrossOver is supposed
to support that as well... certainly would be interesting
to see if that worked (no need for XE2/FireMonkey perhaps?)
