Build debug qwt library under linux

[AlekseyK]

Downloaded qwt-6.1.2.tar.bz2, trying to build under linux:

# qmake qwt.pro -r -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug
# make
Builds release libqwt.so.6.1.2 successfully, but I want to build debug libqwtd.so.6.1.2 library with d-suffix. Why it is not happening?

Tried release, then debug, debug_and_release, build_all - do not help. What is the problem could be? Or it is different under Linux (I do not see debug info include into lib)?

Yes here Linux is way more flexible than Windows - f.e. you don't have this separation between debug/release versions of libraries.
But this goes beyond the scope of a Qwt forum.

Uwe, any good link to read about? And what options in qwt.pro should be?
