regex v1.33.1 match_results::format compile error in vc6

[jeffreyren]

Hello,

I try boost v1.33.1 regex match_results::format in msvc6 sp6, but receive the following error:
	c:\program files\microsoft visual studio\vc98\include\xlocnum(267) : fatal error C1001: INTERNAL COMPILER ERROR
        (compiler file 'msc1.cpp', line 1794) 
         Please choose the Technical Support command on the Visual C++ 
         Help menu, or open the Technical Support help file for more information

Reproduce:
VC6-->Create a MDI application --> add the following code:
    string strfind = "b(.)";
	string Str = "abc";
	string fmt = "x\\1y";

	regex reg(strfind);
	smatch match;
	bool bFind = regex_search(Str, match, reg, match_default);
	if(bFind)
	{
		string Rep = match.format(fmt, format_default);
	}

I want to know if there is any method to support match_results::format compile?
Thanks.

Jeffrey

Unfortunately your compiler is known to be so buggy in this area that there's probably not much that can be done :-(

I assume you can't use regex_replace instead?  That is known to work with VC6.

Alternatively if you take a peak at the code inside regex_replace you'll find that it basically has to do what you're trying to do, so you may find a workaround in there that will also work for your code.

HTH,

John Maddock.

Thanks for your reply.
In fact I have tested regex_replace and it's OK.
The only question regex_replace will replace first or all the occurrences in the string, what I want is to replace the last occurrence.

BTW, is VC6+STLPort can support regex compile in vc6?

Yes, regex_replace will replace the first occurance or all of them, not the last only.

And yes it works with VC6+STLport as well.

Looking at your error, the following code compiles OK for me with VC6, do you have the latest compiler service packs (it's up 5 or 6 now I think) installed?  Otherwise it might be a case of fiddling around with your compiler settings / and or code until you find a combination that doesn't choke the compiler.

John.

Here's the code that works for me:


#include <boost/regex.hpp>

int main()
{
using namespace std;
using namespace boost;

string strfind = "b(.)";
string Str = "abc";
string fmt = "x\\1y";

regex reg(strfind);
smatch match;
bool bFind = regex_search(Str, match, reg, match_default);
if(bFind)
{
  string Rep = match.format(fmt, format_default);
}

return 0;

}

Thanks John, I have found out why.
I'm using VC6 SP6.
Yes, you code works fine for general C++ project VC6 SP6.
But the compiler error occurs only in VC6 mfc-relevant project.
So the better choice seems to be vc6+stlport.

Thanks again for your time!
