Comment (by fscz):
-single_module is added to the linker from the configure script (3496):
----
SHFLAGS='-dynamiclib -Wl,-single_module
-Wl,-install_name,$(SHLIBDIR)/$(SLIBNAME_W\
ITH_MAJOR),-current_version,$(LIBVERSION),-compatibility_version,$(LIBMAJOR)'
----
unfortunately
-install_name
-current_version
-compatibility_version
are also unknown
also problematic is the following line (3499)
---
add_ldflags -Wl,-dynamic,-search_paths_first
---
as search_paths_first throws an error, too
If i remove all those flags and write the following:
---
SHFLAGS='-dynamiclib'
add_ldflags -WL,-dynamic
---
I get the following error:
---
LD libavutil/libavutil.52.dylib

androideabi/4.6/../../../../arm-linux-androideabi/bin/ld:
