Qt4 -vs6-w2k

[jacek]

This one mingw32-make-3.80.0-3.exe.

That explains everything. This file contains only the make program, not the whole toolchain.

Try this: http://prdownloads.sourceforge.net/m...inGW-4.1.1.exe

[dKoder]

Well... I installed the right minGW file, corrected the path in the Autoexec.bat file, and I still have the same problem.

The error states that g++ is not recognized... Do I need to rebuild the debug libraries?

[jacek]

I installed the right minGW file

Where did you install it? Did it install g++.exe there?

Do I need to rebuild the debug libraries?

Start from installing the compiler.

[dKoder]

Here we go again...

I uninstalled QT and minGW and then reinstalled the Windows OpenSource version of QT. Then I ran the (Build Debug Libraries) which produced the follow:

Qt is now configured for building. Just run mingw32-make.
To reconfigure, run mingw32-make clean and configure.

What is moc? Do I need to install the as well?

Frustrated to no end!

[jacek]

I uninstalled QT and minGW and then reinstalled the Windows OpenSource version of QT. Then I ran the (Build Debug Libraries) which produced the follow:

I've just installed Qt 4.2.1 Open Source and ran "Build Debug Libraries". It looks like everything works OK on my system, so there must be something on your system that blocks the build. Maybe you have run out of free disk space?

You can always recompile Qt using the configure utility.

What is moc? Do I need to install the as well?

No, moc (meta-object compiler) is an utility that comes with Qt.

[dKoder]

So what are my options now?

It's late in the game do I punt or pass?

[dKoder]

Well I deleted QT & minWG and reinstalled everything. I ran configure (contents of configure.cache are as follows)

-platform
win32-g++
-debug-and-release
-plugin-sql-mysql
-plugin-sql-psql
-plugin-sql-sqlite
-no-qt3support
-qt-style-windows
-saveconfig

Then I ran the (Build Debug Libraries). After 30-45 minutes or so I'm greated with the folowing errors.

I have a Linux server with both MySQL & Postgres running. I use them both daily, almost, and I have a copy of sqlite on my local machine. During the install the only database QT finds is sqlite and therefore it only builds driver for that database. The first question that comes to mind is why in the sam hill should QT can one way or another whether it can find databases before it will build the drivers? That makes absolutely no sense to me! Anyway, I change to the src/plugins/sqldrivers directory and attempt to build the MySql driver and I get the following errors:

Then I try the postgres driver and I get a similar lenghty error.

I have been trying to get QT to install since last Friday and I don't feel I'm any better off that when I started. Will someone show some conpasion and just shoot me?

[jacek]

-plugin-sql-mysql
-plugin-sql-psql

If you want to build those plugins you must tell Qt where it can find proper libraries. For example like this:

configure -plugin-sql-psql -I C:\Postgres\include -L C:\Postgres\lib
make

(where C:\Postgres is a directory where PostgreSQL libraries were installed).

Everything is explained here: http://doc.trolltech.com/4.2/sql-dri...-7-3-and-above
Note also that you can compile those plugins later (just remember that you shouldn't use paths with spaces).

But you're making a lot of progress. Now you have a working toolchain and you got past that problem with moc compilation.

This is true, however now qmake doesn't work. Before qmake worked to make the Makefile but minwg-32-make didn't now things are reversed and minwg-32-make works and qmake doesen't. So I can't even build the drivers.

Delete the C:\Qt\4.2.1\configure.cache file, open "Qt 4.x.x Command Prompt", run configure (without any parameters) and then mingw32-make and tell me what happened.

[dKoder]

Quick check of executables follows:

C:\Qt\projects\helloWorld>qmake
'qmake' is not recognized as an internal or external command,
operable program or batch file.

C:\Qt\projects\helloWorld>mingw32-make
mingw32-make: *** No targets specified and no makefile found. Stop.

[jacek]

C:\Qt\projects\helloWorld>qmake
'qmake' is not recognized as an internal or external command,
operable program or batch file.

Have you tried it from the "Qt 4.x.x Command Prompt"? Is "C:\Qt\4.1.2\bin" included in PATH environment variable?

[gfunk]

Take a timeout! What are your other options? java? wxWidgets?

If you can spare it, and have experience with Visual Studio, get the commercial edition of Qt w/ the VS integration, it'll be wayyyy easier to use.
