I've recently been installing 1.3 on a fresh system (Perl 5.6.0,
Linux 2.2.16) and noticed some problems.
First, embpexec.pl doesn't seem to be installed by default when I run
'make install'. Previous versions installed it under HTML, so I just
copied it there.
After doing that, I created a hello.epl:
<html>
<head>
</head>
<body>
<p>[+ "hello" +]
</body>
</html>
And running
$ /home/mblakele/lib/site_perl/i386-linux/HTML/embpexec.pl hello.epl
produces the output you'd expect:
<html>
<head>
</head>
<body>
<p>hello
</body>
</html>
But when I try to run Embperl in my sandbox (httpd -X) I get nothing
- not even headers - httpd exits with no message. By adding
PERL5OPT=-d
PERLDB_OPTS='NonStop=1 AutoTrace=0'
I see the following exit message:
Signal SEGV at
/home/mblakele/lib/site_perl/i386-linux/HTML/Embperl.pm line 1193

'*HTML::Embperl::DOC::_1::dbgAllCmds', 'Apache=SCALAR(0x83728e4)')
called at /dev/null line 0
require 0 called at /dev/null line 0
My httpd.conf contains
SetEnv EMBPERL_DEBUG 2797
SetEnv EMBPERL_LOG /tmp/mblakele/embperl.log
<Files *.epl>
SetHandler perl-script
PerlHandler HTML::Embperl
Options ExecCGI
</Files>
AddType text/html .epl
The embperl log shows
[19178]REQ: Embperl 1.3.0 starting... Sun Dec 17 19:41:03 2000

[19178]SRC: Line 4: <p>[+ "hello" +]

So it looks like I'm getting a SEGV just as Embperl tries to eval that string.
I'm not sure if this is related, but... make test succeeded for
offline tests, but the mod_perl testing exited with
Syntax error on line 40 of
/tmp/mblakele/cpan-build/HTML-Embperl-1.3.0/test/conf/httpd.conf:

That line is
use lib qw{ . } ;
But I can run that just fine from the command line, with perl -e. I
suspect an environment problem - perl -V says
%ENV:
PERL5LIB="/home/mblakele/lib/site_perl:/home/mblakele/lib/site_perl/i386-linux:/home/mblakele/lib/site_perl/i386-linux/auto:/usr/lib/perl5:/usr/lib/perl5/i386-linux:/usr/lib/perl5/site_perl/i386-linux:/usr/lib/perl5/site_perl"
@INC:
/home/mblakele/lib/site_perl/i386-linux
/home/mblakele/lib/site_perl
/home/mblakele/lib/site_perl/i386-linux
/home/mblakele/lib/site_perl/i386-linux/auto
/usr/lib/perl5/i386-linux
/usr/lib/perl5

/usr/lib/perl5
/usr/lib/perl5/site_perl/i386-linux
/usr/lib/perl5/site_perl
/usr/lib/perl5/site_perl
.
So it seems like make test is somehow overwriting my @INC (the
/home/mblakele stuff is missing in the error message, and so are the
i386-linux dirs) - or at least ignoring %ENV. But I don't see
anything like this in test.pl
I also tried the debugger:
$ perl -d test.pl -h
Default die handler restored.

...which looks fine. So I'm lost... Any idea why @INC is changing as
test.pl runs? Or why I can't get mod_perl to execute Embperl?
thanks,
