I have read the question, but unfortunately the proposed solutions are to change source code of header files location, which on this case it's not possible.
Let's imagine I have the following structure of system includes from an installed package:
/usr/local/bar/bar1.h
/usr/local/bar/bar2.h
And
/usr/include/foo.h
Important detail:
- bar1.h includes foo.h
- foo.h includes bar2.h
From Bazel, I would right away create a new_git_repository() from /usr/local/bar and then create a library containing the header files from this folder as:
cc_library(
name = "libBar",
hrds = ["bar1.h", "bar2.h"],
deps = ["@foo//:libFoo"],
)
I would do another new_git_repository() from /usr/include/ and create a library:
cc_library(
name = "libFoo",
hrds = ["foo.h"],
deps = ["@bar//:libBar"],
)
As seen, this will end up in a compilation error from Bazel regarding cyclic dependencies:
libBar is dependent of libFoo, and libFoo is dependend of libBar.
Or course a solution would be to separate the libBar into some libBar1 and libBar2. But I would want to avoid this solution as the folder /usr/local/bar contains too many header files and separating this will be a nightmare.
Is there a proper solution for this case?
