[mythtv] Re: compiling mythtv frontend for cygwin

[Buechler, Mark R]

Pretty much the same here. Mythfrontend.exe will startup from either msys or
cmd but immediately segfaults. Starting from cmd shows no output though,
which is standard with Win apps. It looks like it's finding all the files
correctly - or at least mysql.txt. I'm unable to put it in verbose mode to
get more output since that makes it segfault earlier. I need to put some
more debug messages in the code to figure out where it's bombing or attempt
the gdb route.

- Mark.

They are all copied by hand, you'll need mythavcodec*.dll mythavformat*.dll
myth*.dll mythtv*.dll mythfrontend.exe mythtv.exe mythepg.exe mythtvosd*.exe
and mythprogfind.exe in the same directory.
 Also each of the dependency dlls has to be there, ex pthreadsGCE.dll,
freetype-6.dll, zlib.dll, and qt-mt333.dll.  You can also add another
directory to your PATH and put the dlls in that path.

Things may or may not run for you at that point, I played around alot with
my prefix and changed alot of lines to try to elimate posix stuff, but now i
am realizing i probably just had to change that prefix since windows doesnt
really care if you use a / or \ in directories.  Also, QT seems to have
trouble eveywhere myth used iterators in a QStringList, which seems to be
pretty common.  I have been trying to use gdb to find out a little bit more
about why, but have been having a pretty rough time with it.  I think I'm
going to revert back to some older code where I hadn't changed the posix
stuff and then rebuild QT with debug symbols and try again.
