Compiling Qt 4.3.4 with debug on Windows
Message 1 in thread
As the subject says, I'm trying to compile Qt on Windows with debugging
info. I've installed Qt 4.3.4 with MinGW. I've added the mingw-utils.
I've installed the MySQL 5.0.51b no-install sources, and done the
"reimp" thing to both the opt and debug libraries (as mentioned in many
pages). Basically, it looks like this:
C:\MySQL\5.0.51b\lib\opt>reimp -d libmysql.lib
C:\MySQL\5.0.51b\lib\opt>dlltool --input-def libmysql.def --dllname
libmysql.dll --output-lib libmysql.a -k
C:\MySQL\5.0.51b\lib\debug>reimp -d libmysql.lib
C:\MySQL\5.0.51b\lib\debug>dlltool --input-def libmysql.def --dllname
libmysql.dll --output-lib libmysql.a -k
C:\Qt\4.3.4>configure -platform win32-g++ -static -debug-and-release
-no-sql-sqlite -qt-sql-mysql -I c:\mysql\5.0.51b\include -L
c:\mysql\5.0.51b\lib\opt -l mysql
C:\Qt\4.3.4>mingw32-make sub-src
C:\Qt\4.3.4>mingw32-make debug
On the debug build, I get this error:
cd assistant\ && mingw32-make debug
mingw32-make[2]: Entering directory `C:/Qt/4.3.4/tools/assistant'
mingw32-make -f Makefile.Debug

Unfortunately, not being able to find "QtCored4" is EXACTLY why I'm here
to begin with. See, I'm trying to compile Qt with MySQL support such
that I can get the sqlbrowser demo program to work with debugging
capability. In Eclipse (with the Qt plugin), I'm getting exactly the
same error:

Invalid project path: Include path not found
(C:\Qt\4.3.4\include\ActiveQt). sqlbrowser pathentry
1210082005375 1
In my C:\Qt\4.3.4\lib directory, I have a libQtCore4.a, libQtCore.a, and
libQtCored.a, but no libQtCored4.a (obviously).
Does anyone know what's going on here?
Additionally, I'll freely admit that I'm new to Qt in general, and
especially to trying to get the toolchain all set up on Windows. I spent
ALL DAY yesterday, going around in circles, before I finally put it
together how to do what I listed up top here. (In retrospect, it doesn't
seem that hard, but I guess that's how it always is.) So, ANY advice on
how to simply get setup on Windows to build a statically-compiled Qt app
that can access a MySQL database would be GREATLY APPRECIATED!!!
Thanks,

How can I play QuickTime movies with a Qt/Phonon widget on Windows XP?
I've installed the Qt 4.4 demo and run the Media Player demo. This works fine with wmv and other formats, but with QuickTime I only get an audio track. (I've installed a DirectShow QuickTime filter and can play QuickTime in Windows Media Player.)
I realise this isn't really a Qt question, but I'm not sure from the Qt Phonon documentation where else to look.

I don't have any problem following up my own posts, so someone better
tell me if that's not alright... ;-)
Anyway, I just wanted to add that I don't understand where the whole
"QtCored4" thing comes from. I can edit the Makefile.Debug file,
eliminate the reference to that library, and make the debug build by
hand. However, Eclipse will then regenerate that file, complete with the
reference, when I try to do a "debug" build. So where does it understand
that it needs that library? What is telling Eclipse to put that
reference in the Makefile.Debug file?
If I search the ENTIRE Qt source directory, I see the letters "qtcored4"
in files under the demos and the examples (which I will assume don't
count), and under -some- of the *.prl files in the lib directory (which
I think count very much), and the Makefile.Debug files in the "tools"
directories (which I'm not sure about, but that is, indeed, where this
thing is falling down). Again, how does Qt itself know to reference this
thing, when it's apparently not getting created!?
Thanks,
dk
