[mythtv] Re: compiling mythtv frontend for cygwin

[Mario L]

Well your were partially right about the naming scheme, I couldn't
compile eveything as just plain dll, i had to switch the config option
to "plugin".  Compiling was a LOT more straightforward using QT/Win32,
but there are bugs with the cygwin build.  The program actually
launched, but dies immediately just like every other QT app on
QT/Win32.  Apparantly it had trouble writing to my D:\Documents and
Settings\All Users\Application Data/qt_plugin3.rc .  I made sure that
every user had permissions to that directory, and I even tried making
the file first, but still crached a bunch.  I'm getting tempted to
pull out the visual studio CDs now, and put together a project and use
QT/Win32 for VS, but I'm thinking the level of work involved in that
is going to make it impossible to maintain compat with linux/mac os on
the same code.

On another note, I found the exact place in the qmake code that forces
this ../bin prefix to all files.  It is in
/opt/qt/3.2/qmake/generators/unixmake2.cpp.  I guess that chaning that
and using our own "specialized" qmake might work for a very simple
workaround as well.
