IBM ZOS Unresolved static references detected

[bibhudendumishra]

Hi,
I am using xml4c_5_6 on IBM MVS.

While executing a batch program (not from USS) using C++, I am getting following error

ERROR EDC4014: Undefined writable static objects are detected:
xml4c_5_6::XMLPlatformUtils::fgMemoryManager xml4c_5_6::XMLUni::fgXerces
cDefaultLocale

WARNING EDC4015: Unresolved references are detected:

Can you please suggest what could cause this error ?

Thanks

Unresolved external errors are caused by failing to include a source file or a library that defines the variable.

The external error happens when the inlcuded header says there is a variable, but it's not in this file. That is, it is external.

The compiler flags the variable as unresolved but does not generate a fatal error. It is left to the linker to find it. If the linker can't find the definition, then you get this type of unresolved references error.
