Michael,
Thank you for your advice. I think I have been successful
following it, but there was definitely hackery involved. I
thought I'd run my solution by you in case there is yet a
better way.
First, in order to allow
perl Makefile.PL CGI_DIR=/path/to/cgi
I had to add:
$ExtUtils::MakeMaker::Recognized_Att_Keys{CGI_DIR} = 1;
This is undocumented, and hence potentially breakable. Should
this be documented, or is there a better way?
Next, while it was clear that in order to use MakeMaker's
command-line processing, I needed to check somewhere after
MakeMaker was first invoked, but it was not obvious how to do
this. My first strategy was to disect WriteMakefile and do
my $mm = MM->new(...);
..check for CGI_DIR or prompt...
$mm->flush
but that didn't work because it's too late. The right answer
appears to be to check within an overridden method:
sub MY::postamble {
my $mm = shift;
$mm->{CGI_DIR} = prompt( 'Where should cgi scripts be installed? ' )
unless $mm->{CGI_DIR};
"
CGI_DIR=$mm->{CGI_DIR}
install ::
cp -vn cgi/CRRun \$(CGI_DIR)/CRRun
";
}
(This query might live better in MY::post_constants(). Sanity
checking of the entered value is definitely a good idea as
well!)
This approach is not obvious, at least to a MakeMaker neophyte,
and hence might be worthy of a mention in the docs, perhaps
under "Overriding MakeMaker Methods".
If you agree that documentation is the appropriate approach,
then the only honorable thing for me to do is to offer to
create the patch.
