Debugging

[Voldemort]

I've tested and I have 2 problems:

1) How do you put on/off the debugging in CMake?
2) When I restart my program, the file is emptied and the new text is written in the file. But I want to add the new text at the end of the file. How can I do this?

1. I think the answer is in your other post.
2. Use >> (append ) instead of > when you redirect the app outpout.

Which post?

Works fine.

The same way as everywhere - by defining a proper macro.

And what command has the macro to execute? Which arguments does it need?

Did you read the thread I linked to where it's discussed how to turn off debugging output? You have to define a QT_NO_DEBUG_OUTPUT macro for your application! And please don't ask me how to define macros... (hint: "#define" or "-D" compiler option)

I try to compile it:

cmake ../QQMsn -DQT_NO_DEBUG_OUTPUT

cmake ../QQMsn -DQT_NO_DEBUG_OUTPUT

To copy to clipboard, switch view to plain text mode 

Output:

Parse error in command line argument: -DQT_NO_DEBUG_OUTPUT
Should be: VAR:type=value
CMake Error: No cmake scrpt provided.
CMake Error: Problem processing arguments. Aborting.

But what is VAR, type and value? I only has a value (QT_NO_DEBUG_OUTPUT), what are the others?

Take a look at CMakeCache.txt file.

If you want to pass something to the compiler use ADD_DEFINITIONS() command in CMakeList.txt:

ADD_DEFINITIONS( -DQT_NO_DEBUG_OUTPUT )
