I was just wondering; have any of you ever tried to build a resource-only DLL
using the Cygwin toolchain environment?
I mean, starting with a .rc file, build a .res, and then link it into a working
resource-only DLL?
I know that adding resources to executables is perfectly possible; I'm
specifically asking about resource-only DLLs.
If you use Microsoft's tools, you must specify the /NOENTRY linker option to
indicate that the object has no DllMain.
Can we do the analog of this with the GNU-based toolchain on Cygwin?
Not done it - but should be doable - normal MS approach to L14N.
From the links near the bottom, it looks like if you want or need a DllMain,
you have to write and build it, as would be expected, so just don't do that!
See what mintty and setup do with their resources in their build processes:
