Calls to custom built C++ DLLs results in error inside
IDE

Symptom

  • In PowerBuilder, when trying to call an external function from
    a custom built DLL in the IDE environment, the following error
    returns:

  • The same application works when you run as an application
    executable.

Environment

  • PowerBuilder

Reproducing the Issue

In the PowerBuilder IDE environment, run a testcase using the
custom built C++ DLL

Cause

  • Conflict in base address used by PowerBuilder DLL
    (sybcsi_openssl29.dll) and the custom c++ DLL.

  • The sybcsi_openssl29.dll is only loaded in the PowerBuilder
    IDE environment.   It is not loaded when running an application
    executable.

Solution

Recompile the custom c++ DLL to use a fixed address that will not
conflict with 0000000002FE0000.
