I have a simple CGI program written in perl, which is executed frequently (per second). To avoid the CPU load from perl compiling, I chose to use B-C (via perlcc: perlcc -o comment.cgi comment.pl).

The program is:

Show quoted text

use DBI;
use CGI qw/:standard/;

my $cgi = new CGI;

$html=$cgi->request_method();
warn("CGI request is $html");
warn("ENV request is $ENV{'REQUEST_METHOD'}");

When I look at the Apache error log, where WARN output comes when the CGI is executed, the strings are empty. If I run the program without compiling, they are populated.

It seems environment variable handling in B-C compiled perl scripts is completely broken?

Please let me know if there is a way around this.

Distribution name and version: Kubuntu Maverick
Perl version: This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi
Operating System vendor and version: Linux hub 2.6.35-30-generic #56-Ubuntu SMP Mon Jul 11 20:01:08 UTC 2011 x86_64 GNU/Linux

Thank you.

Which B::C release? With 1.34 or latest svn (1.35, r1123) ENV handling and E magic seems to work fine, but I could not test your example yet. Thanks for the report -- Reini Urban

Sorry to miss that - 1.34 The way I am using the script, in this case, is in SHTML (server side include):  </BODY> </HTML> If I run the source script itself, it does output the variables:  </BODY> </HTML> On 09/12/2011 07:28 AM, Reini Urban via RT wrote:

See http://code.google.com/p/perl-compiler/issues/detail?id=75 %ENV keys were not initialized at run-time, just the compile-time values were used. This broke e.g. CGI scripts. Fixed in latest svn with r1135. (The upcoming B-C-1.35) On Mon Sep 12 18:02:18 2011, glen_stewart@associate.com wrote:
