Re: AM_CPPFLAGS not applied for CHECK programs?

[Bob Friesenhahn]

As a follow-up to this posting, I see that when Automake generates a 
specific rule for a target built in a subdirectory, it forgets to 
include $(AM_CPPFLAGS).  This is a serious error.  For example:

coders/coders_art_la-art.lo: coders/art.c
@am__fastdepCC_TRUE@    if $(LIBTOOL) --mode=compile $(CC) $(DEFS) 
$(DEFAULT_INCLUDES) $(INCLUDES) $(coders_art_la_CPPFLAGS) $(CPPFLAGS) 
$(AM_CFLAGS) $(CFLAGS) -MT coders/coders_art_la-art.lo -MD -MP -MF 
"coders/$(DEPDIR)/coders_art_la
-art.Tpo" -c -o coders/coders_art_la-art.lo `test -f 'coders/art.c' || 
echo '$(srcdir)/'`coders/art.c; \
@am__fastdepCC_TRUE@    then mv -f 
"coders/$(DEPDIR)/coders_art_la-art.Tpo" 
"coders/$(DEPDIR)/coders_art_la-art.Plo"; else rm -f 
"coders/$(DEPDIR)/coders_art_la-art.Tpo"; exit 1; fi
@AMDEP_TRUE@@am__fastdepCC_FALSE@       source='coders/art.c' 
object='coders/coders_art_la-art.lo' libtool=yes @AMDEPBACKSLASH@
@AMDEP_TRUE@@am__fastdepCC_FALSE@       DEPDIR=$(DEPDIR) $(CCDEPMODE) 
$(depcomp) @AMDEPBACKSLASH@
@am__fastdepCC_FALSE@   $(LIBTOOL) --mode=compile $(CC) $(DEFS) 
$(DEFAULT_INCLUDES) $(INCLUDES) $(coders_art_la_CPPFLAGS) $(CPPFLAGS) 
$(AM_CFLAGS) $(CFLAGS) -c -o coders/coders_art_la-art.lo `test -f 
'coders/art.c' || echo '$(srcdir)/'
`coders/art.c
