[Qt-interest] build errors

Fortunately it does not, otherwise you would find one day that your other compiler stopped working.

Environment variables should be set either by user for a specific session if you would like to work command prompt or handled by environment if you prefer to use UI.

Example is VS. It provides a special bat files to open command window and set appropriate environment (32 bit, 64 bit for every VS version ).

And it is better to avoid adding hardcoded path to the system path, even though the same VS allows this.

This leads to problems if you have multiple compilers installed on the same system.

When I worked on Windows with Qt I also came across this thing. It's a shame that the default windows Qt installer does not add itself to the default system PATH.

Here's what I did:
Control Panel -> System -> Advanced -> Environment Variables

Added this to PATH: (!!!!"Add" means append!!!!)

C:\Qt\2010.01\qt\bin;C:\Qt\2010.01\bin;C:\Qt\2010.01\mingw\bin;
(use whatever Qt directory you have)

Based on your error file it seems that it pulls the visual c++ stuff instead of the standard lib :)
Since the PATH is read from left to right if it's an include situation and you want your visual c++ stuff untouched adding the above may not be the resolution. If you put it to the end of the PATH, it never will be reached when iterating through the libraries and if you put it before the visual c++ directories it will mess them up (but worth a try :)).

I suggest you hack around with the .pro file.
You could add INCLUDEPATH to the .pro file with for example: C:\Qt\2010.01\mingw\include\string.h

I hope some of these helps you :)

Cheers,

Bence

I am a new user of Qt.

I installed the SDK  and am using Qt Creator 2.0.1
I have Microsoft Visual C++ 6.0 and Microsoft .NET 1.1 (2003) installed on my Windows XP machine.

When I try to compile a sample QT app (animation framework >  animated tiles( I get many, many build errors and warnings.
They seem to be arising from #include files from MS VC 6

I think it has to do with the environment variables INCLUDE and PATH.

When I look at those variables, I see nothing pointing to Qt files.

Questions
1)  How do I resolve the build errors?
2) If changes to the environment variables are needed, how do I confine them to Qt and not affect the VC 6.0 builds?

 I have attached the compile output and the environment variables.

Thanks in advance.

Alby
