| Subject: | [RT #7742] MakeMaker: handling source files in subdirs |
What follows is a ticket which has been languishing in the Perl 5 RT
queue since being filed by Sven Verdoolaege in Sept 2001. It seems to
me to be more of a user question than a bug report. I am duplicating it
here in this queue in the hope that someone can respond and enable us to
close the original ticket.
Thank you very much.

What is the correct way of dealing with source files in
other directories with MakeMaker ?
Makefile.PL in the Gtk subdir of the Gtk-Perl package,
passes a bunch of "xs/file.o"s as OBJECT to MakeMaker,
but the only rule it generates for these files is
.c$(OBJ_EXT):
$(CCCMD) $(CCCDLFLAGS) -I$(PERL_INC) $(DEFINE) $*.c
But that basically amounts to "cc -c xs/file.c" with a bunch
of defines, which will create a file.o in the current directory
and not in the xs directory, whereas to make the rule specifies
a dependency of xs/file.o on xs/file.c .
(This is with perl 5.7.2, btw)
What is the best way to resolve this ?
Similarly, in my own module (FCGI), I have some *.c files in
a different directory (../libfcgi) whose object files I would
like to appear in the current directory.
How do I tell MakeMaker about these *.c files ?
Right now I do this:
my $extrarules = join "\n",
map { $b = $_; $b =~ s/\.c$//; my $s="$devkit/libfcgi/$b.c";
"$b\$(OBJ_EXT): $s\n\t".
'$(CCCMD) $(CCCDLFLAGS) -I$(PERL_INC) $(DEFINE) '."$s\n"; }
@dist2;
eval 'package MY; sub postamble { $extrarules; }';
Is there a better way ?
