Bug in automake parsing of Makefile.am

[Roger Leigh]

Hi,

I think I have found a bug in automake:

I have the following in configure.in:
if test x${BUILD_TEST} = xyes ; then
  TEST_BIN='$(TEST_BIN)'
fi

If I have this in Makefile.am it works fine:
TEST_BIN = testdither escp2-weavetest unprint escp2-unprint pcl-unprint 
bjc-unprint
noinst_PROGRAMS = @TEST_BIN@
EXTRA_PROGRAMS = escp2-weavetest unprint escp2-unprint pcl-unprint bjc-unprint 
testdither

but if I just have this in Makefile.am:
AM_CONDITIONAL(BUILD_TEST, test x${BUILD_TEST} = xyes)

and this in Makefile.am:
if BUILD_TEST
TEST_BIN = testdither escp2-weavetest unprint escp2-unprint pcl-unprint 
bjc-unprint
else
TEST_BIN =
endif

noinst_PROGRAMS = $(TEST_BIN)
EXTRA_PROGRAMS = escp2-weavetest unprint escp2-unprint pcl-unprint bjc-unprint 
testdither

I get the following errors:
test/Makefile.am: testdither_OBJECTS should not be defined
test/Makefile.am: escp2_weavetest_OBJECTS should not be defined
test/Makefile.am: unprint_OBJECTS should not be defined
test/Makefile.am: variable `LDADD' not defined
test/Makefile.am: escp2_unprint_OBJECTS should not be defined
test/Makefile.am: variable `LDADD' not defined
test/Makefile.am: pcl_unprint_OBJECTS should not be defined
test/Makefile.am: variable `LDADD' not defined
test/Makefile.am: bjc_unprint_OBJECTS should not be defined
test/Makefile.am: variable `LDADD' not defined

However, the outputted Makefile will have
noinst_PROGRAMS = $(TEST_BIN)
in both cases.  It seems that when automake parses Makefile.am, it
cannot cope with make variables in any special automake definition,
and will only allow plain names or @VAR@ substitutions with AC_SUBST.

I have attached the configure.in and Makefile.am used to this
message.  This is a patched copy of files from gimp-print CVS.

Regards,
Roger
