My application relies on two statically-linked libraries, we'll call them a and b. Both libraries, plus the application,
 call VxWorks API functions, which reside in libvx2qnx.a. (This is the VxWorks->QNX porting library. It reimplements the
 VxWorks API using Posix and QNX API calls). I added all three libraries to the "extra libraries" list in the linker 
properties for the app.

The linker is able to resolve vx2qnx calls that originate from the app, but is unable to resolve vx2qnx calls that 
originate from libraries a and b.

I don't want to include libvx2qnx.a in the "extra libraries" list for libraries a and b, because I don't want a and b to
 have separate, though identical, implementations for each VxWorks API function. I want all VxWorks API calls to go to 
the same chunk of binary code.

I tried rearranging the order of the "extra libraries" list for the app, placing libvx2qnx.a first, before libraries a 
and b, but that didn't make any difference.

Any suggestions, anyone?
