While installing e.g. DBD-Oracle-1.14, dmake aborts with:
dmake.exe: Error -- Multiply defined recipe for target C
Dmake doesn't like what the current DBI::DBD::dbd_postamble generates:
# --- MakeMaker postamble section:
# --- This section was generated by DBI::DBD::dbd_postamble()
DBI_INST_DIR=C:/opt/perl/site/lib
DBI_INSTARCH_DIR=C:/opt/perl/site/lib/auto/DBI
DBI_DRIVER_XST=$(DBI_INSTARCH_DIR)/Driver.xst
# The main dependancy (technically correct but probably not used)
$(BASEEXT).c: $(BASEEXT).xsi
# This dependancy is needed since MakeMaker uses the .xs.o rule
$(BASEEXT)$(OBJ_EXT): $(BASEEXT).xsi
$(BASEEXT).xsi: $(DBI_DRIVER_XST) $(DBI_INSTARCH_DIR)/Driver_xst.h
$(PERL) -p -e "s/~DRIVER~/$(BASEEXT)/g" < $(DBI_DRIVER_XST) > $(BASEEXT).xsi
# these two keep make -j4 working
$(DBI_DRIVER_XST) :: pm_to_blib
$(NOECHO) $(NOOP)
$(DBI_INSTARCH_DIR)/Driver_xst.h :: pm_to_blib
$(NOECHO) $(NOOP)
# ---
# End.
The problem is the colon in the absolute paths.
>From the dmake doc:
Since the rule operator begins
with a `:', traditional versions of make do not allow the
`:' character to form a valid target name. dmake allows
`:' to be present in target/prerequisite names as long as
the entire target/prerequisite name is quoted. For exam-
ple:
a:fred : test
would be parsed as TARGET = a, PREREQUISITES={fred, :,
test}, which is not what was intended. To fix this you
must write:
"a:fred" : test
Which will be parsed as expected.
It seems that quoted targets are sufficient.
Attached is a possible patch for DBI::DBD.
