Library $USEREXT/xxxx.dll does not have a LibInit function

Error Message

This error can occur when trying to load a user created extension:"Library $USEREXT/xxxx.dll does not have a LibInit function"

Cause

User-created DLLs don't apply to the dependency list in the Extension Make script. Only extensions (.avx files) and ESRI created DLLs (avdlog.dll, avgrid.dll, avnet.dll, and so forth) are to be used in the dependency list of the Make script.

See the ArcView help topic "Extension Dependencies" for more information.
