Hi,
I'm trying to use hash_map (gcc 3.2.2) with a std::string as the key. It
will compile if I use <map> but I get a bunch of template compile errors
when I change it to hash_map. Any suggestions? My program and the errors
are below...
#include <ext/hash_map>
#include <string>

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>

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.

It depends. You might like to have a look at my "Hashing.hh"
header (in the code at kanze.james.neuf.fr/code-en.html---the
Hashing component is in the Basic section). Or for a discussion
and some benchmarks,

article is a little out of date now, as I've tried quite a few
more hashing algorithms. But the...

Hi,
I am wondering if there are any functional differences between SGI's
hash_map and tr1's unordered_map. Can these two containers be
interchanged? What would it take to switch from hash_map to
unordered_map? Thank you.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
