When linking with CRTLIB.LIB, the problems listed below can cause the
following message when linking a main program to the C run-time DLL
created as described in the MTDYNA.DOC file supplied with the C
Compiler Version 5.10:
.... error : L2029 : '__iob' : unresolved external
The problems that can cause this message include the following:
1. Compiling with the wrong include files. Typically, this involves
compiling without the /I option, as described in MTDYNA.DOC.
2. Compiling without defining the symbol DLL. DLL must be defined in
any program that calls the C run-time library DLL.
These options, as well as other important information, are covered in
Section 5.2 of MTDYNA.DOC.
