errors in porting on gcc 3.4.6 from gcc 3.2.3

errors in porting on gcc 3.4.6 from gcc 3.2.3

[kushwaha]

hi all..

Following is the part of a code giving error with gcc 3.4.6  which
previously compiled with gcc 3.2.3. As i am porting the software so can't
change the code. is there any way to get it compiled without modifying
actual code??


//BpHashMap.h

template <class TKey, class TValue>
class BpHashMap {

  public :

    TValue getValue(TValue val);
    TKey getKey(TKey key);
};


class HString_Key {

    const char* mpcId;
    unsigned long mulId;

  public :

    HString_Key() : mpcId(" "), mulId(0) { }
    HString_Key(const char* apcId, unsigned long aulId) : mpcId(apcId),
mulId(aulId) { }

};


template <class T>
class Equal_to_HString_Key {

    HString_Key  key;

  public :

    Equal_to_HString_Key(const char* apcCallId, unsigned long apcHashId) {
      key.mpcCallId = apcCallId;
      key.mulHashId = apcHashId;
    }

    void Id();
};


//BpHashMap.C

#include "BpHashMap.h"
#include <iostream>

using namespace std;

template <class TKey, class TValue>
TValue
BpHashMap<TKey, TValue>::getValue(TValue val) {
    TValue t = val;

    return t;
}

template <class TKey, class TValue>
TKey
BpHashMap<TKey, TValue>::getKey(TKey key) {
    TKey t = key;

    return t;
}

// just to find the result of compilation
int main()
{
    BpHashMap<char, int> obj1;

    cout<<obj1.getValue(25);
    cout<<endl;
    cout<<obj1.getKey('a');
    cout<<endl;

    return 0;
}

Are you sure...? Compiling your code (gcc 4.1.2) I get:

error: ‘class HString_Key’ has no member named ‘mpcCallId’
error: ‘class HString_Key’ has no member named ‘mulHashId’

from these lines:

    key.mpcCallId = apcCallId;
    key.mulHashId = apcHashId;

and sure enough, your class template HString_Key does not contain those 
members. I don't see how this could have compiled with gcc 3.2.3. Didn't 
you mean:

    key.mpcId = apcCallId;
    key.mulId = apcHashId;

in Equal_to_HString_Key::Equal_to_HString_Key(...) ? Compiles ok for me 
with this change.

[kushwaha]

yes.. the code is correct and getting compiled on gcc 3.2.3. i just want to
know is there is any option to avoid that strict checking on gcc 3.4.6 as i
can't change the code.

Please don't quote sigs.

Please don't top-post (rearranged)

... for some slightly strange value of "correct" ;)

Well, the offending template doesn't actually appear to be used in the 
code, so I guess gcc 3.2.3 just ignored it; I've had a brief look if 
there are any flags for gcc that might suppress checking of templates 
that are never instantiated, but couldn't find anything that works. Sorry,
