[Live-devel] Help with link error

[Roland]

Hi Melvin

 

Do a FindInFiles for the symbols that aren't being resolved, e.g.
"tunnelOverHTTPPortNum" or "statusCode". Then figure out if that source file
where these variables are being defined is included in the compilation of
the .LIB or the final .EXE. Add the corresponding source file to one of
those projects and recompile. E.g. for the "tunnelOverHTTPPortNum" variable,
you'll find "extern" references and one real declaration in
testProgs\playCommon.cpp. Add playCommon.cpp to resolve this issue.

 

Same goes for the other unresolved symbols. e.g. class "Locale" is defined
in "liveMedia\Locale.cpp"...
