How do I link multiple libraries in a Firebreath plugin?

Does anyone know where I can find a Firebreath sample (either Mac OS X or Windows) that illustrates how to create a plugin that includes 1 or more other libraries (.DLLs or .SOs) that each rely on other sub-projects built as static libraries (LIBs)?

For example, let's say that the Firebreath plugin is called PluginA, and that PluginA calls methods from DLL_B and DLL_C. DLL_B and DLL_C are C++ projects. DLL_B calls methods from another project called LIB_D, and DLL_C calls methods from a project called DLL_E.

Therefore, the final package should contain the following files:

PluginA.dll
DLL_B.dll (which also incorporates LIB_D)
DLL_C.dll
DLL_E.dll

I am currently forced to dump all source files in the pluginA solution, but this is just a bottleneck (for example I cannot call libraries written in other languages, such as Objective-C on Mac OS X).

I tried following the samples on Firebreath, but couldn't get them to work, and I found no samples from other users that claimed they were able to get it to work. I tried using CMAKE, and also running the solutions directly from X-Code, but the end result was the same (received linking errors, after deployment DLL_C couldn't find DLL_E etc.)

Any help would be appreciated - thank you,

You're way overthinking this.

On windows:

  • DLLs don't depend on a static library because if they did it would have been compiled in when they were built.
  • DLLs that depend on another DLL generally just need that other DLL to be present in the same location or otherwise in the DLL search path.
  • Those two things taken into consideration, all you need to do is locate the .lib file that either is the static library or goes with the .dll and add a target_link_library call for each one. There is a page on firebreath.org that explains how to do this.

On linux it's about the same but using the normal rules for finding .so files.
