Hi!

I was just trying to use the stlsoft::malloc_allocator with the std::map from the Visual C++ 6.0 compiler. This brought up a compile error and I was wondering if anyone has an idea if that is an error on my side or maybe an incompability issue.

Here is the error:

c:\programme\microsoft visual studio\vc98\include\xtree(587) : error C2664:
'void __thiscall stlsoft::new_allocator<struct
gtl::CMemoryTracker::SMemoryInfo>::deallocate(struct

Here is the code line from the Visual C++ 6.0 _Tree implementation that causes the problem:

void _Freenode(_Nodeptr _S) {allocator.deallocate(_S, 1); }

Marc Kamradt

In case you are wondering. I was trying to see if the error also occurs when I use the new_allocator. The error is the same with the new_allocator and the malloc_allocator.

Regards,

Marc Kamradt

Hmm ... surprised but not shocked.

I'm planning to release 1.6.5 next week, so will have it sorted by then.

Sorry for the inconvenience.

Cheers

Great! I'll give it another try with the next release.

Ok, here're the problems:

- The VC++ 6 (and prev) STLs need for the first parameter to an allocator's deallocate() to be void *, not T*. So I've fixed that by having it be of type deallocate_pointer, which is defined appropriately in all allocator classes.

- The VC++ 6 (and prev) STLs assume the presence of a _Charalloc() member,
which has the semantics of a single-parameter allocate(), and which returns
char *. I've added a conditionally compiled function into all allocator
classes.

- As it transpires, the DMC/SGI requires that the allocate() and deallocate() methods are static, so I've added that into all classes as well, except winstl::shell_allocator as it has a member pointer to the shell allocator (even though this has been the COM task allocator since about Win98 / NT4 sp ??).

These changes will be in 1.6.5, which I'm hoping to release this week. There's a lot of repeated crufty stuff here, and so I plan to factor all but the mem-api-specific stuff into a base template, which all specific classes will share, for 1.7.1

btw, please note that VC6 and prior do not implement the fourth template param of map correcty. It should be

  new_allocator<pair<const int, int> > (substitute your allocator type here)

but is

 new_allocator<int>

There's nothing I can do to help here, I'm afraid, but there's a simple example in ./test/stlsoft/allocator_test2/allocator_test2.cpp in the next release which shows the ifdef-ing necessary to get a portable solution.

Cheers

Matthew
