error when compiling with clang

Recommended Posts


compiling systemc-ams-2.1  with clang version 7.0.0

using systemc-2.3.3 

yields the following error :

   sca_core::sca_implementation::sca_port_base* pobj; 

in the file


from private to protected fixes the issue.

Any ideas ? Is this a compiler issue ? Not really that confident about changing from private to protected.

(I tried gcc just as a sanity check and it doesn't give this error or warning).

apart from that, the fix for memcpy() and memset() and a few warnings  about

warning: 'register' storage class specifier is deprecated and incompatible with C++17 [-Wdeprecated-register]

it compiles fine.

Thanks in advance and thanks for the code !

Best Regards

Thanks for reporting these compilation issues! These will need to get addressed by the COSEDA Technologies GmbH with a new SystemC AMS release. In the meantime, you can fix the compilation issue by replacing:




The calls to memcpy() and memset() need to get prefixed with the std:: namespace prefix. The "register" storage class specifiers can be safely removed. If I see it correctly, they are only remaining in file scams/impl/analysis/ac/sca_ac_domain_entity.cpp.
