Re: mod_perl, compilation issues, cont

[tomcat/perl]

Thank you very much for your reply below. I was getting desperate of getting 
any at all.
I will check the permissions issue and post back to the list.
Maybe in the mneantime an additional question to the list : has *anyone at all* succeeded 
in installing (and using) Apache 2.4 / perl 5.20+ / mod_perl 2.x on a Windows 10 platform ?
Knowing that someone else has been able to do that, would already help me in focusing my 
debugging efforts to something specific to my laptop.

grant directory listing rights but not read rights for the process that’s doing the 
compilation…

See: 
https://www.online-tech-tips.com/computer-tips/set-file-folder-permissions-windows/ under 
Permission Types; the specific right is ‘List Folder Contents’

This would account for both dl_findfile working and the ‘Can’t Load file’ error because 
the first utilizes the listing rights and the second needs to actually read the file.

Can anyone tell me what the error below really means ?
(and if possible, give me a clue as to what may be happening ?)

To get possibly more details, I re-ran the compile command after setting PERL_DL_DEBUG 
in the environment (just something I found in Dynaloader.pm). It does give some more 
detail, but I am still stumped..

Full config described below.
D:\develop\06_SVN\AP2lib\trunk\modlib\AUTH\UMA2.pm is my module, which compiles just 
fine on Linux servers with similar software installed (Apache, mod_perl, perl).

---------------------

OS : Windows 10
Apache httpd 2.4.41

MSWin32-x64-multi-thread

Problem :

C:\>perl -cw D:\develop\06_SVN\AP2lib\trunk\modlib\AUTH\UMA2.pm

Line 28 of UMA2.pm is :

use Apache2::Const -compile => qw(:common :http :methods :override :proxy :log REDIRECT 
AUTHZ_GRANTED AUTHZ_DENIED AUTHZ_DENIED_NO_USER AUTHZ_GENERAL_ERROR);

(wrapping due to email)

C:/Strawberry/perl/site/lib/Apache2/Const.pm line 19 is :

use ModPerl::Const ();

File C:\strawberry\perl\site\lib\ModPerl\Const.pm exists, but has no 
"load_file" in it.

The file C:/Strawberry/perl/site/lib/auto/ModPerl/Const/Const.dll exists.

For non-german-speakers, the above message "load_file:Das angegebene Modul wurde nicht 
gefunden" translates as "load_file:the specified module was not found".

The above module "UMA2.pm" compiles without error on a Linux server with similar httpd, 
perl and mod_perl versions.

Any clue or additional questions welcome.
Thanks
