STL hash_map

Hi All,

I am developing my code with Apache stdcxx. I am bound to use STL of
Apache only.
Now today I need hash_map in code but as I learned, it is not
available in Apache since it is not standard c++. Though it is
available with GNU STL.

The code module where I use hash_map will generate separate object
file during compilation. This code module is also using STL string.

What can I do now ?

I planned like this way:

1The code module that uses hash_map, I will link it statically with
GNU STL.
2The rest of the modules, which does not use hash_map, I will link it
dynamically with Apache STL.

By this approach my object size of GNU STL (which is linked statically)
is huge in size.

Can anybody please suggest me a better solution with following
conditions in mind?

- I must use hash_map.
- I must use Apache STL.

Mixing two different standard libraries sounds like a nightmare
and may not even be possible.

Just use Apache STL and then a "third party" hash_map. By
third party I mean some code that is easily included and
compiled into your project.

If you can do this with the GNU hash_map (e.g. it's defined
withing a single header file) then go right ahead.

If not, you could use some other hash_map that fits my own
ease of use critria. Boost's hash_map comes to mind although
I don't think it's called a hash_map. I'd go with boost.

Good luck.

I need help in hashmaps. Why doesn't this work: #include <hash_map> hash_map <int, string> hm1; typedef pair <int, string> pr; hm1.insert(str_pair(1, "Hello")); It compiles, but crashes at runtime, pointing to something in xhash.

Hi there, I would much appreciate your help with the following problem. Below is the code that uses a hash_map. I want to release all the memory occupied by the hash_map for other use. Apparently clear() function is not working and the trick with swap() is half working. Does anybody know how to deallocate the hash_map? Thanks in advance. Kon #include <functional>
