41I would like to convert between sc_int and sc_bv like in this example:
42*/
43
44#include "systemc.h"
45
46int sc_main(int argc, char* arg[])
47{
48    sc_int<10> a;
49    sc_bv<10> b;
50    sc_int<7> c;
51
52    a=10; cout << "a="<< a << "\n";
53    b=a; cout << "b="<< b << "\n";
54    c=b; cout << "c="<< c << "\n";
55
56    return 0;
57}
58
59/*
60This doesn't work on with either SC5.0 or g++ for different reasons.
61
62SC 5.0
63------------------------------------
64compile error at assignment "c=b" == sc_int<7> = sc_bv<10> :
65
66"/view/ccss_ulli/vobs/abc/src/scenic/scenery/include/sc_lv.h", line 165: Error: The function "convert" must have a prototype.
67"str.cc", line 12:     Where: While instantiating "sc_bv_ns::sc_lv<7>::sc_lv(const sc_bv_ns::sc_bv_base&)".
68"str.cc", line 12:     Where: Instantiated from non-template code.
69
70file sc_lv.h:
71#if !defined(__SUNPRO_CC)
72  template<class Y> sc_lv(const sc_proxy<Y>& y)
73    {init(y.back_cast().length()); assign_(y);}
74  template<class T> sc_lv& operator=(const sc_proxy<T>& t)
75    { sc_bv_ns::assign_(*this,t); return *this;}
76#else
77  // at least some constructors
78  sc_lv(const sc_bv<W>& t){convert(t);verify_length();}
79  sc_lv(const sc_lv_base& y):sc_lv_base(y){verify_length();}
80  sc_lv(const sc_bv_base& t){convert(t);verify_length();}
81#endif
82
83Apparently, the "convert" function is undeclared.
84
85
86With gcc
87------------------------------------
88compiles fine, but then Abort at assignment "b=a" == sc_bv<10> = sc_int<10> :
89
90a=10
91Abort (core dumped)

93
94
95I am using SystemC 1.0.1 (stellar does not yet have a 1.0.1 release entry). on
96a Solaris 5.5.1 host with SC5.0 or g++ 2.95.2
