Hello Sir dakupoto,
I completely agree with you.
As a beginner to SystemC(or C/C++ programming in general), I had faced some issues when trying to use SystemC after its installation(following instructions in INSTALL) on my Ubuntu system.
I was unable to link SystemC shared library. Later I figured out LD_LIBRARY_PATH variable was not set somehow which caused me trouble. This is when the above link came to my rescue.
As a beginner, I am not sure if this has to be taken care by user or installation process itself.
