I'm having problem compiling one of my projects with VS2005. The
problems arise with VS2005 (apparent?) inability to compile log4cpp.

Has anyone succesfully compiled log4cpp using VS2005?

Here are the errors I get:

Error    1    error C2039: 'iterator_category' : is not a member of
'log4cplus::helpers::string_append_iterator<_Container>'    c:\program
files\microsoft visual studio 8\vc\include\xutility    572
Error    2    error C2146: syntax error : missing ';' before identifier

Error    4    error C2602: 'std::iterator_traits<_Iter>::iterator_category' is

Ideas, suggestions and (most of all) fixes welcome ...

What version of log4cpp are you using? I tried grabbing the latest code
(v0.3.5) from sourceforge and found only a VC6 workspace that contains a
bunch of broken projects - it doesn't look like anyone's done any VC++
maintenance on this project for a couple years, and even then they were
using a year out of date version of VC++..

Hi Carl, I'm using v1.0.2 - please see http://log4cplus.sourceforge.net/
Yes, I agree dev has kinda halted on this (last fix was in '04) - but I
have a lot of other code using the log4cpp dll and it would be a
nightmare to strip it out and use another library ...

Cheers

OK, that version is much closer to working. I had to make 2 changes to get
it to compile with VC 2005:

replace all occurrences of __value with something else: __value is
recognized as a keyword by the VC2005 compiler (the authors of log4cpp
should not have used it - all identifiers containing two consequetive
underscores are reserved to the implementation).

For the specific error you're seeing, insert the following line of code into
\include\log4cplus\helpers\stringhelper.h, line 123:

typedef std::output_iterator_tag iterator_category;

I didn't try testing the library, but it builds with those two changes.

-cd

Thanks for the quick response Carl - I'll make the modifications now and
then test it later with my apps - I'll let you know how it goes.
