strange linker error

[darth_vector]

i am getting a strange linker error:

! Error: Unresolved external '_eh' referenced from /src/objdir/nwadump.o

the source file contains a call to a function "eh" that is defined in a header file called gpib.h - used for instrumentation programming.

the reason the error is strange is that there is no reference to "_eh" in nwadump.o whatsoever!

i have checked, double checked and tripple checked all of the source files and can find no problem. any help would be appreciated.

Check that you are linking to the library that gpib.h is the header of.

thanks, but thats not it. i am linking the relevant libraries.

The name is being mangled, and probably correctly. That means: you're missing a library.
