1849:14: error: friend declaration of ‘int compare_unsigned

[aqib]

Hi 

I am trying to install systemC 2.2.0 but it was giving ‘int compare_unsigned", "mutable" and "gets" error. Through your forum I have removed "mutable"  and fgets error. now problem is when I run @make" it pops up following error of "int compare_unsigned" . Is anyone have clue about this error. Thanks in advance for your time and help.

SystemC 2.2 is quite old, may be incompatible with modern compilers. Why not to use SystemC 2.3.3 ?

Thanks Roman for quick response. I am doing simulation on Noxim which requires syctemc2.2.0.

Well, compiler error is self-explanatory. I see this particular issue is fixed even in SystemC 2.3.0
