Recommanded way to have multiple staticlib with corrosion

[OlivierLDff]

I have 2 crate that depends on cxx, when I try to create a project that link to the 2 of them, I get linking error, as symbols for cxx object are defined more than once.

I've stumble across that: dtolnay/cxx#883

I'm unsure how to solve the problem in practice. I will investigate on my side, but has anyone sucessfully integrated 2 cxx crates using corrosion? Is there an example somewhere?

It's not a cxx issue, it's a general rust issue: rust-lang/rust#104707

I've been thinking (but haven't had the time to implement) about adding an abstraction to Corrosion that does the following:

• Create a dummy wrapper package that has a staticlib library target, and depends on all the libraries you need. This should be automatically created by a CMake function corrosion_create_wrapper_staticlib(new_lib_name dep_1_crate ...).
• The dependencies would need to have an rlib target, so that cargo can link them into the wrapper crate.
• corrosion currently ignores rlib only libraries, so potentially one would need to add a staticlib to import the actual cxx libraries, even if they will not be used directly, just to make corrosion aware that these libararies exist.

Ok, have you ever integrated 2 libraries yet with a workaround?
I guess I will go with the one crate with everything in it as it seems to be the faster solution now.
