# In case both shared libs and static libs are enabled, it can happen |
|
# that a user might want to link e.g. libavformat statically, but |
|
# libavcodec and the other libs dynamically. In this case |
|
# libavformat won't be able to access libavcodec's internal symbols, |
|
# so that they have to be duplicated into the archive just like |
|
# for purely shared builds. |
|
# Test programs are always statically linked against their library |
|
# to be able to access their library's internals, even with shared builds. |
|
# Yet linking against dependend libraries still uses dynamic linking. |
|
# This means that we are in the scenario described above. |
|
# In case only static libs are used, the linker will only use |
|
# one of these copies; this depends on the duplicated object files |
|
# containing exactly the same symbols. |
