The procedure entry point XXXX could not be located in the dynamic link library LLLL.dll


Symptom:

When trying to run an executable within the debugger a message box is displayed containing the following error message:

The procedure entry point XXXX could not be located in the dynamic link library LLLL.dll

for example:

The procedure entry point ?Dump@C2DataDefnSet@@UBEXAAVCDumpContext@@@Z could not be located in the dynamic link library MCOMN.dll

The entry point (‘XXXX’) and library (‘LLLL.dll’) may vary.

Causes and Remedies:

The library that is being used does not contain the entry point (i.e. procedure/function) needed. There are a number of possible causes for this:

  • An old library is being used.
    • If a newer version of the library is available then try that. It may be that a new procedure has been added to the library that was not available in the old.
    • Check that the expected version of the library is in the path. It may be that there is an old version of the library in the path and that is being used instead of the expected one.
    • Check the 'working directory' within the project settings.
  • If this error is encountered after upgrading a library then consider reverting back to the old one. It may be that the new version no longer contains an entry point that the old one supported and which the application requires.
  • It may be that one of the dlls other than the one specified is causing the problem.

These notes have been tested with Windows NT4.
