We compile the following code with gcc (historically 2.95.3,
egcs-2.91.66 or VC5/6 on Windows).
template<class X> class mapTags {
public:
typedef void (X::*thisfunc)();
static commandTags<X> mustags[];
std::map<string, thisfunc> quickfindtag;
// Looks up function call for this name, and does it, if defined
int doCommand(X* thisclass, const char* funcname)
{
// See Stroustrup III, p 420
commandTags<X>* tags = mustags;
if (quickfindtag.empty()) {
// fill quickfindtag map with all the entries in mustags array
while (tags->name != NULL) {
quickfindtag.insert(std::pair<string, thisfunc >(tags->name,
tags->func));
++tags;
}
}
// find tag in quickfindtag map
std::map<string, thisfunc>::const_iterator functionIterator =
quickfindtag.find(funcname);
if (functionIterator != quickfindtag.end()) {
thisfunc func = functionIterator->second;
(thisclass->*func)(); // run function
return 1;
}
return 0; // function not found
}
};
I have just installed Fedora Core 4 and am trying to compile it with gcc
4.0.0 (Redhat 4.0.0-8). However I get the error message:
FmDisplay.h: In member function 'mapTags<X>::doCommand(X*, const char*)'
FmDisplay.h:61: error: expected `;' before 'functionIterator'
FmDisplay.h:62: error: 'functionIterator' was not declared in this scope
I do not know why this is happening. I installed gcc 2.95.3 and got
exactly the same error message so it is possibly to do with the Fedora
installation rather than gcc.
The same code compiles ok on Solaris 5.6/7 with egcs-2.91.66 and on
Redhat 8.0 with gcc 2.95.3.
Thanks in advance.
Mike
