What should the output look like ?

if is something like "$0.0"

ui->label->setText(QString("$%1").arg(APP_VERSION, 2, 'f', 1);

would be way simpler and clean

This will expand all the macros so you can see what the compiler is complaining about.

gcc -E -o output.c input.c

More information here: http://gcc.gnu.org/onlinedocs/gcc/Preprocessor-Options.html

This is one reason macros are frowned upon.
