  1. I've been using SystemC for years on Linux with gcc and Windows with Visual Studio. I decided to try it out in Eclipse on windows with the Cygwin environment. Several problems have popped up. For example there are #ifdefs around defining data types supported by the compiler, such as __int64 in the Microsoft compiler versus long long elsewhere. However these are defined based on the _WIN32 predefined macro. That's not really correct, it should be defined based on the compiler type - in this case using _MSC_VER instead of _WIN32. Example from sc_nbdefs.cpp // Support for the long long type. This type is not in the standard // but is usually supported by compilers. #if !defined(_WIN32) || defined(__MINGW32__) const uint64 UINT64_ZERO = 0ULL; const uint64 UINT64_ONE = 1ULL; const uint64 UINT64_32ONES = 0x00000000ffffffffULL; #else const uint64 UINT64_ZERO = 0i64; const uint64 UINT64_ONE = 1i64; const uint64 UINT64_32ONES = 0x00000000ffffffffi64; #endif
