Create a C++ DLL project. Try to export more than 64K (65,536) functions, classes and members of classes from it. Now build this project.

Back to the top

While building the C++ DLL project, it throws LNK1189 error.
The exact error message is …..The limit of 65535 objects or members in a library has been exceeded.

 

Back to the top

In the MSDN Library, this error message has the following description:
LIBTOOMANYMEMBERS:: library limit of number objects exceeded
The limit of 65535 objects or members in a library has been exceeded.

64k is the maximum limitation for the library for export symbols. There is no way to go beyond this limit.
It’s a expected behavior and built into the format of a library; a limitation from the compiler for DLLs.

Back to the top

The only possible resolution is to have a lesser number (less than 64K) of exports from the library.
Consider dividing the DLL into two (or more) to limit the number of exports in each to less than 64K.
