confused by difference bewteen setting debug/release in creator build and .pro

[wysota]

Try qmake -config debug

[AndyBrice]

That didn't work either.

I added:

-config debug

As additional args for the debug build in creator and left the .pro as:

CONFIG = qt warn_on resources uic

Notice the -O2 flags in the output, so it is still building as release:

I found the answer on Stackoverflow. Looks like the answer is to do this in the .pro file:

CONFIG -= debug_and_release
CONFIG( debug, debug|release )  {
  CONFIG -= release
}
else {
  CONFIG -= debug
  CONFIG += release
}

CONFIG -= debug_and_release
CONFIG( debug, debug|release )  {
  CONFIG -= release
}
else {
  CONFIG -= debug
  CONFIG += release
}

To copy to clipboard, switch view to plain text mode 

This seems to work , but Yuk! Surely there must be a more elegant way?

[wysota]

A more elegant way to do what exactly?

[AndyBrice]

Set CONFIG to 'debug' or 'release' from the Creator IDE, without having to modify the .pro file.

[wysota]

How did the pro file look like initially? I really have no problems in modifying CONFIG when invoking qmake

The Release mode enables optimizations and generates without any debug data, so it is fully optimized. . Lots of your code could be completely removed or rewritten in Release mode. The resulting executable will most likely not match up with your written code. Because of this release mode will run faster than debug mode due to the optimizations.
