SCV error on peekRandom function

[Josep Sans 0]

Hi I have compiled scv-2.0.1 and after link it to my project I'm having trouble with this error. Can somebody help? Thanks

 

scv-2.0.1/src/scv/scv_bag.h:489:16: error: cannot assign to non-static data member within const member function 'peekRandom'
      _randomP = new scv_random(nameP(),_seed);
      ~~~~~~~~ ^

Which compiler version do you use? _randomP is declared as mutable so it should be possible to assign to it even in const member functions. Or maybe you have a define named 'mutable'?

Hi,

I've compiled the SCV library with clang (version 11.0.0) and g++ (version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC))

and my uvm-SystemC testbench where I use SCV for randomize my transaction with clang

All configurations yielded to the same errror.

Thanks

Hi Josep,

After building SCV, did you run 'make check'? Did all tests pass?

If so, could you share a small example that reproduces your problem?

For me, 'make check' runs successfully using SystemC 2.3.3 and g++ 9.1.0.

Thanks

Hi,

After a clean compile with g++ (version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)), at executing 'gmake check' I get the following errors:

It seems that you are mixing compiler versions and/or settings between the different packages you use. At least, your SystemC installation has not been built with the default GCC 4.8.5. Although not strictly necessary, I'd recommend to build SystemC, UVM-SystemC and SCV with the same compiler version and -options.

I can confirm that with GCC 4.8.5, the SCV 'make check' also runs successfully.

Thanks, this was the problem. The SystemC library was compiled with a different compiler.
