Include Qt - Designer into the build process

[rudi]

It looks like Designer is pretty much usable under OS/2. Have still not tested it extensively, but with the patch proposed in ticket #47 it's quite O.K.

Qt-Designer in action

I can confirm that Designer works fine now. Dmitry, you made an excellent job, thank you.

Patch, proposed by Rudiger in ​http://svn.netlabs.org/qt3/ticket/47 is useful as well.

A little remark, which Rudiger didn't mentioned.

Due to OS/2 limitation (if you don't have win32k.sys driver installed) DLL base name max length is 8 chars, while QT want to build some plugins (cppeditor.dll dlgplugin.dll ) with longer names. To overcome this I manually edit def file to short the module name in LIBRARY statement and rename the result dll to truncated name.

Also, it seems that the only names which must be exported from QT plugin are

  "qt_ucm_query_verification_data"
  "ucm_instantiate"

the rest QT will access via COM interface. So .def file can looks like

LIBRARY <8 chars module name> INITINSTANCE TERMINSTANCE 
DATA MULTIPLE NONSHARED 
EXPORTS
  "qt_ucm_query_verification_data"
  "ucm_instantiate"

Best regards Dmitry

Yes, I ran into DLL naming problem as well. My fix was to add the following to the *.pro file (CPPEDITOR.PRO in this case):

# Rudi: added for 8.3 DLL names
os2:TARGET      = cppedit

Done in r197 and r196.

When building Qt Designer, we hit some limits of IBM's linker. This may result in a broken executable. It is suggested to switch to GCC3.3.5 + OpenWatcom? linker (as used in Qt 4.5.2). r201 includes the necessary changes.
