Can I use #ifdef in a .def?

conditional-compilation, dll, function

Solution

No, not possible, it is not a file that's pre-processed. Although I supposed you could by running the preprocessor to generate another .def file and link that one.

The more effective approach is to eliminate the need for a .def file completely. Use __declspec(dllexport) in your code on the functions that should be exported. Then any #ifdef in that code will automatically ensure that a function is neither compiled nor exported.

Problem

Can I use `#ifdef` sections in a `.def` file for a dll? E.g.: ``` LIBRARY "mydll" EXPORTS checkRequirements createDevice installDriver isPastVersionInstalled removeDevice #ifdef myVar doSomethingElse #endif ```
