dnl *** finalize CFLAGS, LDFLAGS, LIBS
dnl Overview:
-dnl GST_OPTION_CFLAGS: common flags for profiling, debugging, errors, ...
-dnl GST_ALL_*: flags shared by all built objects
-dnl GST_OBJ_*: additional flags to link to the core library
+dnl GST_OPTION_CFLAGS: common cflags for profiling, debugging, errors, ...
+dnl GST_ALL_*: vars shared by all built objects
+dnl GST_LIB_LDFLAGS: additional linker flags for all libaries
+dnl GST_OBJ_*: additional vars to link to the core library
dnl include GST_ALL_*
dnl GST_LT_LDFLAGS: library versioning of our libraries
dnl GST_PLUGIN_LDFLAGS: flags to be used for all plugins
dnl - src and build dirs need to be added because every piece that gets built
dnl will need the GStreamer source and generated headers
dnl LIBS: XML doesn't need to be added because we don't explicitly use symbols
-dnl from LibXML
+dnl from LibXML except for in the core library

dnl FIXME: check if LTLIBINTL is needed everywhere
dnl I presume it is given that it contains the symbols that _() stuff maps to
GST_ALL_LIBS="$GLIB_LIBS $LTLIBINTL"
-dnl LDFLAGS modifier defining exported symbols from built shared objects
-EXPORT_LDFLAGS="-export-symbols-regex [_]*\(gst_\|Gst\|GST_\).*"
dnl LDFLAGS really should only contain flags, not libs - they get added before
dnl whatevertarget_LIBS and -L flags here affect the rest of the linking
-GST_ALL_LDFLAGS="$EXPORT_LDFLAGS -no-undefined"
