Hi, I've installed qt-win-opensource-4.2.3-mingw.exe from trolltech and
I'm using the tools installed by cygwin to develop Qt programs. Well,
one could argue I'm not really using cygwin because I have to pass
-mno-cygwin when compiling otherwise I get errors for non-trivial programs.
Anyway, -mno-cygwin makes the executables dependent on mingwm10.dll
instead of cygwin1.dll, correct? Since my QT programs depend on this dll
I can only start them from a cygwin shell since cygwin itself is not in
windows path (and I don't think it should be).
My question is how safe is it to put mingwm10.dll in the windows path so
I can start my qt programs from explorer? That would mean having two
copies of the same dll in the path under cygwin...which I know is bad
for cygwin1.dll. I was thinking of writing a startup script that checks
that the files are identical so I know when I need to update the copy. I
also tried to put a shortcut to the dll but that didn't work which was
very unfortunate I think.
Any comments welcome...sorry for being off-topic, but maybe this is of
interest to people using cygwin and maybe want to develop Qt programs
and don't have a real mingw installation (I don't).

PS. I know -mno-cygwin is probably going to be removed in a future
version of cygwin's compiler, does that mean I would have to maintain a
real mingw installation to develop Qt programs? I have MSVC++ as well,
but I believe the Qt version for MSVC++ costs money. Maybe I will buy
that later when I really need a debugger I can wrap my head around, heh. DS.
