// When building a rlib or staticlib, +bundle means that all object files from the native static
|
||
|
|
// library will be added to the rlib or staticlib archive, and then used from it during linking of
|
||
|
|
// the final binary.
|
||
|
|
|
||
|
|
// When building a rlib -bundle means that the native static library is registered as a dependency
|
||
|
|
// of that rlib "by name", and object files from it are included only during linking of the final
|
||
|
|
// binary, the file search by that name is also performed during final linking.
|
||
|
|
// When building a staticlib -bundle means that the native static library is simply not included
|
||
|
|
// into the archive and some higher level build system will need to add it later during linking of
|
||
|
|
// the final binary.

// This modifier has no effect when building other targets like executables or dynamic libraries.
