In our current Rust world, we have the following dependency structure:
xul.so --------------------------+
|
xul-gtest.so -+--> xul.a --------+-> gkrust
|
+--> gkrust-gtest
This structure results in link errors with multiply-defined symbols
between gkrust-gtest and gkrust with newer Rust releases when linking
xul-gtest.so. So we have to do something different.
Our new structure is:
xul.so --------------------------+
|
xul-gtest.so -+--> xul.a --------+-> gkrust --+-> gkrust-shared
| |
+--> gkrust-gtest --------------+
and we enforce that a given shared library can only have at most one
Rust library that it depends on. Said Rust library is assumed to
include all significant Rust dependencies of the dependent static
libraries as well. (In the above structure, gkrust is simply a wrapper
around gkrust-shared, so gkrust-gtest doesn't have to include gkrust as
a dependency.)
