Game_Ender:
I know the maker says its not supported but has anyone tried it?

drac:
STLFilt has been updated, a quote from the webpage
--- Quote ---gcc version now supports ALL recent gcc releases (tested up to 4.2.2)!
--- End quote ---

I have successfully used it with C::B 8.02 and MinGW 3.4.5.

Here is the program I've tested:

--- Code: ---#include <iostream>
#include <map>
#include <string>
#include <iterator>

using namespace std;

int main()
{
map<int, string> months;

months.insert(1, "January");
months.insert(2, "February");

copy(months.begin(), months.end(), ostream_iterator<pair<int, string> >(cout, "; "));
}
--- End code ---

The error message without filtering:

I think that everyone that wants to learn to use STL should have this tool installed and enabled :D

Edit: oh, and here are the steps to "install" STLFilt:

* Download gSTLFilt
* Install ActivePerl
* Rename "c:\Program Files\CodeBlocks\MinGW\bin\mingw32-g++.exe" to mingw32-g++2.exe
* Copy gstlfilt.zip\c++.exe to c:\Program Files\CodeBlocks\MinGW\bin\ and rename it as mingw32-g++.exe
* Copy gstlfilt.zip\gSTLFilt.pl to c:\Program Files\CodeBlocks\MinGW\bin\
* Copy gstlfilt.zip\Proxy-gcc.INI to %windir% (aka c:\windows)
* Edit %windir%\Proxy-gcc.INI under [common]
--- Code: ---filter_script=c:\Program Files\CodeBlocks\MinGW\bin\gSTLFilt.pl
toggle_file_dir=c:\Program Files\CodeBlocks\MinGW\bin\
native_gcc=mingw32-g++2.exe
perl_exe=c:\perl\bin\perl.exe
--- End code ---

* Create a empty file named "filtering.on" in c:\Program Files\CodeBlocks\MinGW\bin\
And... that's it!

That is beautiful, drac.

I wonder if the Perl requirement is an obstacle.

drac:
Edit: I forgot that C::B is a multiplatform application. What I wrote down is specific to Windows platform. On other platfroms perl is not such a big dependency because it's already installed :)

Well, I've installed perl only for this too.

The alternative is to transform gSTLFilt.pl into an executable, here are two ways:

* By using PAR and pp
Install ActivePerl
Run from a console window

--- Code: ---set path=%path%;c:\perl\bin;"c:\Program Files\CodeBlocks\MinGW\bin\"
cpan
install PAR
install pp
q
set path=%path%;c:\Perl\site\bin\
pp gSTLFilt.pl -o gSTLFilt.exe
--- End code ---

This takes allot of time and the resulted binary gSTLFilt.exe is 2.5Mb in size with
a speed penalty at first run, on subsequent runs the CPU is going up for one to
two seconds.

The binary is an executable + a zip file containing the required parts of perl to run.

* By using Perl2Exe
You don't need to install perl for this to work. The resulted binary is 500kb, there is no high CPU
usage at first run. The downfall is that you have a message nag for two seconds at exit.

If you want to use gSTLFilt.exe instead of gSTLFilt.pl you should modify %windir%\Proxy-gcc.INI
like this:

--- Code: ---filter_script=.
perl_exe=c:\Program Files\CodeBlocks\MinGW\bin\gSTLFilt.exe

--- End code ---

The dot for filter_script will give a Warning, but other than it should work fine. You can modify
the source code and rebuild the proxy executable to get rid of the Warning, also to search
for the ini file in the directory where it was run and not in %windir%...

Perl2Exe gives the best results, but I didn't want to buy it only for one script, so
installing perl was good enough.

Please put this on the Wiki (I mean your whole article, of course). That's cool stuff. 8)
