Hello,
I have the following scenario:
Product {
name: "some-headers"
}
// Implementations of some-headers
// A-1 and A-2 define the same symbols and are mutually exclusive.
// An application product can only depend on one of them at a time
StaticLibrary {
name: "A-1"
Depends { name: "some-headers" }
}
StaticLibrary {
name: "A-2"
Depends { name: "some-headers" }
}
// Can be linked to both, A-1/2
// But it must always appear after A-1/2 on the linker command line
// of a dependent application.
StaticLibrary {
name: "B"
// Not sufficient to make B link after A-1/2
Depends { name: "some-headers" }
// Can not do that because it would make "app" link to both
// A-1 and A-2 to app.
// Depends { name: "A-1" }
// Depends { name: "A-2" }
}
CppApplication {
name: "app"
// Selects one of A-1 or A-2, but never both
Depends { name: "A-1" }
Depends { name: "B" }
}
Since I don't explicitly specify a dependency between A-1/2 and B, the link
order is undefined, i.e. B may appear before A-1/2. Is there any way to tell
Qbs that B must always appear after A-1/2 in the library list of app?
Thanks
Richard
