mod_perl, compilation issues, cont

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

MSWin32-x64-multi-thread

as per Apache log :

Problem :

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

BEGIN failed--compilation aborted at D:\develop\06_SVN\AP2lib\trunk\modlib\AUTH\UMA2.pm 
line 28.

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

Additional info :

I checked the permissions of all below c:/strawberry/perl, and one thing I can say is that 
all directories and files below that point have at least permissions read/write/execute 
for all "authenticated users".

On the other hand, I also ran the following (why did I not think of that before ?), just 
to make sure that the issue would be reproducible with only the "vanilla" installed Apache 
2.4, perl 5.26.3, mod_perl 2.x :

(Note : to make extra sure, I also ran this in a CMD window "run as administrator"; the 
results are the same.)


Any other clue, anyone ?

Re: mod_perl, compilation issues, cont

Posted by "André Warnier (tomcat/perl)" <aw...@ice-sa.com>.
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.
