| I'm having a problem with an undefined symbol during linking which has me perplexed.
My application uses an external C-language library (built as a static library with a .a extension [ libSCCE.a ]). The library calls an external function SCCE_TempLexName(char*) which it expects the host application to provide.
My (host) application implements this function as follows:
in SSCE_TempLexName.h : #if defined(__cplusplus)
extern "C" {
#endif
void SSCE_TempLexName (
char * outPath );
#if defined(__cplusplus)
}
#endif
in SSCE_TempLexName.cpp: void
SSCE_TempLexName (
char * outPath )
{
... C++ body - the content doesn't matter here
}
The implementation is explicitly (and needs to be) a C++ function because it uses C++ class objects in its implementation.
MY PROBLEM: The linker has an undefined symbol error: "SSCE_TempLexName(char*)", referenced from: getTempFileName() in libSCCE.a(DFTLEX.o) saveLexFile(DFTLEX*) in libSCCE.a(DFTLEX.o)
This worked in my CodeWarrior projects, but it obviously doesn't here. Can someone point out what I am doing wrong??
