All List Members, Our project has to use a portable Xml Library in both Unix
( many POSIX variants ) & Windows I designed a C++ Wrapper Reader , Writer classes on
LibXml2 based C API.. Everything worked fine ( in single Threaded Windows &
Multithreaded UNIX ) & my Wrapper Library ( .Lib Only VS 2005 project in
Windows – No Dlls & .a in UNIX ) behaved same in Linux/Solaris &
Windows machines , without any code changes. The client exe was also the same in both UNIX &
Windows My Windows settings were as follows………. Client ( exe ) -> Wrapper ( .lib ) Statically Link
-> Orig LibXml2 (implicit linking to Import Lib – libxml2.lib &
libxml2.dll present at Runtime) Since our project has to read & write Xml files within
various threads , it worked perfectly well in UNIX multithreading environment. But crashed in Windows Multi-threaded environment (
xmlParse(FileName or Memory API ) ) I used /MT ( Static Link to C Runtime ) throughout in the
Wrapper as well as my client ( statically linking to my Wrapper Lib ). I finally got hold of all the .C source files of LibXml2
& compiled them in VS 2005 as well as old VC6 & changed
accordingly all my Wrapper & Client to VS 2005 or VC 6 projects But the problem remained. We have to finally build the Wrapper in Xerces C++ API (
as Xerces VC 6 , VC7 , VC8 Solution along with the source is freely available )
, which ran fine in both Unix & Windows multithreaded environment. My LibXml2 Wrapper was definitely faster as it was in C
& I would like to run it in Windows MultiThreaded environment if somebody
can help. I know original LibXml2.dll , iconv.dll & zlib1.dll
were all built in the old VC6 Environment. It would be nice , if a LibXml2 VS 2005 Solution project
is provided along with the source code as Xerces guys have done . ( In VS2005 Environment Crash Occurs in msvcr80.dll
