debug variant of kdelibs4 port is not debuggable

[mkae (Marko Käning)]

Would be really cool to have a debug variant of this port!

[mkae (Marko Käning)]

I realized that it is easy enough to implement by simply adding

variant debug description "Enable debug." {
    configure.args-append  -DCMAKE_BUILD_TYPE=Debugfull
}

But for some reason I was still unable to step into the libraries with gdb/Xcode. :-(

I did set the environment variable:

DYLD_IMAGE_SUFFIX=_debug

Any hints what could have gone wrong?

The cmake portgroup already defines a debug variant, but capitalises "debugFull" differently.

[mkae (Marko Käning)]

Thanks jmr for the hint. I'll try to rebuild kdelibs4 in that variant now. Hope that fixes the debugging issue I keep having.

Although the debug variant of mine seems to install fine "port contents" eventually doesn't show any *_debug-libraries as the result. It looks like the port does not

/opt/macports-test/share/apps/cmake/modules/KDELibs4LibraryTargets-debugfull.cmake, however, seem to say that the debug versions of the libraries don't have the "_debug" suffix anyway:

# Import target "KDE4__kdecore" for configuration "Debugfull"
SET_PROPERTY(TARGET KDE4__kdecore APPEND PROPERTY IMPORTED_CONFIGURATIONS DEBUGFULL)
SET_TARGET_PROPERTIES(KDE4__kdecore PROPERTIES
  IMPORTED_LINK_INTERFACE_LIBRARIES_DEBUGFULL "Qt4::QtDBus;Qt4::QtCore;-lpthread;-framework Carbon"
  IMPORTED_LOCATION_DEBUGFULL "/opt/macports-test/lib/libkdecore.5.6.0.dylib"
  IMPORTED_SONAME_DEBUGFULL "libkdecore.5.dylib"
  )

...or, do I misunderstand this?

[mkae (Marko Käning)]

Well, eventually I am able to debug into KDE's libs. (With my debug-variant from above. Didn't test the +debugFull variant again.)
