问题
I managed to set up build project in dll mode and in library mode but not together:
for build in dll:
- project->properties->Configuration Type: Dynamic Library (.dll)
- project->properties->Target Extension: .dll
for build in library:
- project->properties->Configuration Type: Static library (.lib)
- project->properties->Target Extension: .lib
it is possible to build both of them together?
回答1:
Yes, you can have single project that can be used for .dll and .lib.
Steps to be followed:
- Visual Studio will provide you Debug and Release solution configurations. Create custom configurations for lib and dll (i.e. lib-release, dll-release).
- For each configuration set different project type and set export symbols. i.e. for lib-release define LIB_CONFIG and don't set it for dll-release.
- In code file use LIB_CONFIG with #IFDEF to include/exclude project type specific code. IF some part of code is lib specific the add it in #ifdef LIB_CONFIG...#endif, and if it is dll specific add it in #ifndef LIB_CONFIG...#endif.
- Compile project after changing Active solution configuration. i.e. change to lib-release, if you want to have .lib file.
I hope this will help you. Please let me know your feedback.

During creation of new project in Visual Studio, make sure you check on "Export Symbols"

No. You must have two projects in your solution (using the same source files). Don't forget to have different names for your 2 .lib files.
EDIT: use some trick to not include a DllMain function in your static lib (either some #ifdef, or a separate file not added to the static project)
