gstreamer1 @1.16.2 controller-enumtypes.c:6:1: error: stray \ in program (due to make >= 4.3)

[kencu (Ken)]

I ran into errors building gstreamer and friends on Tiger with the error above. It looks like this in the log:

:info:build controller-enumtypes.c:10: error: stray '\' in program
:info:build controller-enumtypes.c:10: error: stray '#' in program
:info:build controller-enumtypes.c:10: error: expected '=', ',', ';', 'asm' or '__attribute__' before string constant
:info:build controller-enumtypes.c:11: error: stray '\' in program
:info:build controller-enumtypes.c:11: error: stray '#' in program

apparently this construct

:info:build /opt/local/bin/glib-mkenums \
:info:build --fhead "#ifdef HAVE_CONFIG_H\n#include \"config.h\"\n#endif\n\n#include \"controller-enumtypes.h\"\n\n\#include \"gstinterpolationcontrolsource.h\" \n\#include \"gstlfocontrolsource.h\"" \
:info:build --fprod "\n/* enumerations from \"@filename@\" */" \
:info:build --vhead "GType\n@enum_name@_get_type (void)\n{\n  static volatile gsize g_define_type_id__volatile = 0;\n  if (g_once_init_enter (&g_define_type_id__volatile)) {\n    static const G@Type@Value values[] = {"     \
:info:build --vprod "      { @VALUENAME@, \"@VALUENAME@\", \"@valuenick@\" }," \
:info:build --vtail "      { 0, NULL, NULL }\n    };\n    GType g_define_type_id = g_@type@_register_static (\"@EnumName@\", values);\n    g_once_init_leave (&g_define_type_id__volatile, g_define_type_id);\n  }\n  return g_define_type_id__volatile;\n}\n" \
:info:build gstinterpolationcontrolsource.h gstlfocontrolsource.h > controller-enumtypes.c

doesn't work with make versions >= 4.3 <​https://bugs.gentoo.org/705974>.

There are patches in that gentoo ticket for the gstreamer* series.

• WARNING: Backward-incompatibility! Number signs (#) appearing inside a macro reference or function invocation no longer introduce comments and should not be escaped with backslashes: thus a call such as:

      foo := $(shell echo '#')
  

  is legal. Previously the number sign needed to be escaped, for example:

      foo := $(shell echo '\#')
  

  Now this latter will resolve to "\#". If you want to write makefiles portable to both versions, assign the number sign to a variable:

      H := \#
      foo := $(shell echo '$H')
  

  This was claimed to be fixed in 3.81, but wasn't, for some reason. To detect this change search for 'nocomment' in the .FEATURES variable.
