When you install the DLL files a number of libraries will be installed. These libraries correspond to the DLLs with the same names. They are required for linking with C/C++. If you are using a linker that can not process the library files you may need to build your own library files. You can do this using vensim.h, vensim.c and vensim.def that are installed when you install the external function sources. You will need to modify these to correspond to the DLL file you want to use.
The library files installed are vendll32.lib, vendlm32.lib, vendlx32.lib, vdpdll32.lib, vdpdlx32.lib. If you install the 16 bit Vensim the 16 bit variants of these are installed.
In addition to the library files the include file vendll.h will be installed in the DLL directory. This file contains function prototypes for use with any C or C++ programs.
