c++.stlsoft - MinGW compatibility question

reply "John Abney" <johnNOSPAMPLEASEabney yahoo.com> writes:
Hello again!

I thought I should mention that I ran into a small issue with MinGW 3.1.0
when compiling a program that used the WinSTL registry functionality.  In
the included version of the standard library, std::wstring doesn't look like
it gets defined, but the compiler winds up hitting the #else half of the
"#if defined" listed below.

#ifndef _STLSOFT_STRING_ACCESS_NO_STD_STRING
 #if defined(__STLSOFT_COMPILER_IS_GCC) && \
     __GNUC__ < 3
  typedef stlsoft_ns_qual_std(basic_string)<ss_char_w_t>
_stlsoft_wstring_t;
 #else
  typedef stlsoft_ns_qual_std(wstring)
_stlsoft_wstring_t;

Since std::wstring doesn't get defined for me, presumably because I'm not
using STLPort, I got a long series of errors.

In my program, I worked around this by including the following in my source
code (this is by no means a permanent fix, but I stuck it in there to get me
off the ground):
#include <string>
namespace std
{
 typedef basic_string<wchar_t> wstring;
}

For the purposes of mothballing this problem, you can use
reg_key_sequence_test.cpp.  Here's a version of reg_key_sequence_test.cpp
that includes the quick fix I used before.

Anyway, this problem is easy to work around, but I wanted to stick a note on
here before I forgot about it.

I can't download anything from MinGW other than 3.2.3 (although it's listed

If not, do you have the url you used to get the installer for your version?

It's going to be pretty messy trying to maintain compatibilities, unless I
can get the one you've used.

That's the link that I used, and in my C:\MinGW\doc\MinGW, the docs all
indicate that I'm running MinGW-3.1.0.  Is there some other way to check?
Either way, that's the link that I used.  Maybe MinGW and gcc run different
version schemes?

Let me know if there's anything else you need to know about my installation.

Also, I see that MinGW is not explicitly supported by STLSoft, so there's
probably no point in you worrying about this.  I'd always thought that gcc
and MinGW were very closely tied together, but it looks like things may not
be packaged the same way.

Although maybe we're talking at cross purposes. It's possible that MinGW
discuss a separate version to the version of GCC.

Anyway, if this is the version you have, I have enough to go on, so I'll
give it a bash.

Anyway, I realize MinGW's not officially supported, so don't bend over

anything else that I might run into.

Well, MinGW is my prime source of GCC, since I'm wont to boot the Linux box

tables on the site, it should just say GCC 2.95, 2.96 and 3.2. So I could
weasel out by saying 3.2.3 is not supported. However,  the only reason

Don't hesitate to remind me about this in a few weeks. ;)
