Qt4 Book Says “Make a Release,” Reality Disagrees

Question

Depending on different sources, for a Qt4 application, you create release or debug versions using "make release" or "make debug". In real life, they make mistakes.

make: *** No rule to make target `debug'.  Stop

Only naked makeup works. I am not sure what it produces. Running strip reduces the size of executable files, but gdb cannot find characters in an unbuilt file. I am using qt4.6.2 on Arch Linux.

So, what is the right way to determine whether to release or debug?

Answer 1

Add

CONFIG += debug_and_release

.pro , qmake. debug release ( ) .
