ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

the parameter here is a char* or could be std::string
Code:
objLogger.logMsg("test"); // compiler error on this line
it looks like you are trying to create a wrapper class for a string and theres really no need if you use an std::string; it has a func which returns a const char* (c style string).
While I agree with dmail that rolling your own string class is a waste of time, unless it's an assignment or for learning purposes, this compiles just fine:
Code:
class String
{
public:
String(const String &) {}
String(const char *) {}
};
static void logMsg(const String &) {}
int
main()
{
/* logMsg expects a const String reference and String has a
constructor that takes a const char * and the literal "foo"
is of that type. It wouldn't work, however, if logMsg didn't
take a const reference because you can't bind a reference to
a temporary. */
logMsg("foo");
return 0;
}
no matching function for call to `String::String(String)'
candidates are: String::String(char*)
String::String(String&)
initializing argument 1 of `int Logger::Print(String)' from
result of `String::String(char*)'
Huh? In your first post you indicated that you were porting from Solaris to Linux and you encountered that problem, now you say it's the other way around. Compile my program, without modification, on both platforms, paste compiler output/version for each. Seems to me you're using a poor implementation of the C++ standard on one of the platforms.
