If you missed the fact that recursive makefiles are harmful, there is
plenty of documentation online (try "Recursive makefiles considered
harmful"), or ask the libav developers for the more concise version.
This change and the previous ones, are particularly boring though. The
main motivation is to eventually address #9397, after the same change is
applied to codec/, demux/ and possibly a few other subdirectories.
Note that some more simplification between Makefile.am files and
configure.ac is definitely possible - if someone is bored.
This provides a more traditional set of library function calls than the
VDPAU specification defines. Furthermore, this has libvdpau.so as a
conditional run-time linking dependency.
Note that this requires libvdpau 0.6 or later (0.4.1-8 on Debian) at
run-time due to a bug in libvdpau versions 0.4 through 0.5.
Unfortunately, we cannot emit NEON opcodes when NEON is not explicitly
enabled (-mfpu=neon), contrary to MMX & SSE on x86. As a consequence,
this will not work for inline assembler in a non-optimized plugin,
namely the deinterlacer.
There is also a(n hopefully theoretical) bug whereby the compiler would
emit NEON instructions in the descriptor or activation callback of a
NEON plugin. This could then crash if NEON is not supported, even
before the NEON run-time check is reached.
* Generate the plugins cache for the build tree during make all
(if not cross-compiling).
* Generate the plugins cache for the installation during make install
(if not staging with DESTDIR).
+ New build system, using recursive makefiles. Due to the amount of code
in VLC, this had become unavoidable.
+ Removed the check for OS X's stack size, since our automake targets are
a lot less hungry now.
+ Ditto for Solaris's sed.
+ Since automake-1.6 is faster than 1.7, use it first if both are present.
* m4/vlc.m4:
+ New AX_ADD_CPPFLAGS, AX_ADD_CFLAGS, AX_ADD_CXXFLAGS, AX_ADD_OBJCFLAGS
and AX_ADD_LDFLAGS macros that do all the magic to detect possible
modules and register their flags.
+ New AX_ADD_BUILTINS and AX_ADD_PLUGINS macros.
+ Some magic to generate vlc-config.
* configure.ac:
+ Moved most code to the AX_ADD_* macros.
+ Explicitely added all target Makefiles.
* modules/**/Modules.am:
+ Path to sources are now relative to Modules.am's directory level.
