gcc-4.1.1 qt-2.3.10 compile errors
Message 1 in thread
Hello,
We are moving to gcc-4.1.1 for our software packages and am having
trouble getting the C++ in QT-embedded to build with the newer
compilers.
Does Troll Tech still support qt-embedded-2.3.10?
My question is related to the fact that I use OPIE and qt-2.3.10 is
still the recommended version for OPIE develpment, just wondering if
anyone has any patches for 2.3.10 to work with gcc-4.x
So far I have patched
qwindowsystem_qws.h -
qpixmapcache.cpp -
but now it fails on. Gettin worried that this will continue for a
while.

Anybody out there patched this C++ stuff to work with new compilers yet?
That would be sweet.
If not, I guess I can do it all and submit the patch if anybody wants
it.
Thanks,
Brian

Message 2 in thread
I have finally "I think" patched qt-2.3.10 to build with gcc-4.1.1
uClibc-0.9.28.1. It seems to build correctly and run ok.
Here is the diff if anybody is interested.
After hours of googling, I still could not find all the answers to
getting this to build correctly. So hopefully this will help anybody
with the same problems.
It didnt end up being as much as I thought it would be, thankfully. But
lots of virtual declaration warnings on non-virtual destructors.
C++ got real picky in 4.x I guess.
anyway
