I fixed it. It seems one symlink was missing from:
Code:

ln -s /var/cache/zoneminder /usr/share/zoneminder/www/cache

I note that this thread solved my issue a while back, but I just did an emerge sync and then update world, BUT I forgot to lock down zoneminder,
and it was upgraded to 1.30.4. Well, my once working zoneminder will no longer start. I am having some trouble figuring out
why it will not start. /var/log/messages seems to indicate that there is a problem with libmysqlclient.so.18.4.0, and also with AnalysisFPS, but
for some reason I feel like that might be a red herring.

Also note, I upgraded the db with zmupdate.pl, it seemed to run without incident.

Here is the output of /var/log/messages after I start zoneminder.

Code:

The above output just keeps repeating as the pl script tries repeatedly to launch the zm.

zmadit.pl gets stuck in a loop, and spits this out until you break it:

Code:

Argument "Porch1" isn't numeric in numeric comparison (<=>) at /usr/bin/zmaudit.pl line 196.
Argument "Porch2" isn't numeric in numeric comparison (<=>) at /usr/bin/zmaudit.pl line 196.
Argument "Garage" isn't numeric in numeric comparison (<=>) at /usr/bin/zmaudit.pl line 196.
Argument "back_porch" isn't numeric in numeric comparison (<=>) at /usr/bin/zmaudit.pl line 196.
Argument "back_door" isn't numeric in numeric comparison (<=>) at /usr/bin/zmaudit.pl line 196.


Porch{1,2}, Garage, back_door and back_porch are monitors, I see that in /var/lib/zoneminder/events they are symlinks
to 1,2,3,4,5

I do not recall if they were like that before the upgrade, but the time stamps on directories 1,2,3,4,5 are from
yesterday when I installed.

The last time this happened it was a libmysqlclient update issue... Not sure why it is doing this now. Any suggestions?

Thanks.

Update to my previous post.

I realized through some other reading that the AnalysisFPS was in fact an error, and I fixed that with the following mysql command:

Code:

 alter Table `Monitors` change column `AnalysisFPSLimit` `AnalysisFPS` decimal(2,2);


Now, it seems my libmysql error has moved to a libc error:

Code:

That message just means that the faulting instruction was in libc. It is probably an application misuse of a C library function, such as passing a null pointer where that is not permitted. We would need to know the faulting function, register context, and preferably a backtrace to diagnose the problem. You will need to build the affected modules with debug symbols (CFLAGS including -ggdb and FEATURES including one of nostrip or splitdebug).

I am not sure if this is what you are after, but I enabled debug and did a trace on /etc/init.d/zonemidner and received the following:

I now see this in /var/log/messages:

Running zmc from the command line, and I am pretty sure that will break anyway, gives:

I've installed 1.32.3 and seems it worrk, but I can't access to api:
when I test api version http://[server]/zm/api/host/getVersion.json i recive "The requested URL /zm/api/host/getVersion.json was not found on this server."

This is my apache2 config file for zoneminder (10_zoneminder_app.conf)
Code:

ScriptAlias /zm/cgi-bin/ "/usr/libexec/zoneminder/cgi-bin/"
<Directory "/usr/libexec/zoneminder/cgi-bin">
    Options +ExecCGI
    AllowOverride All
    Require all granted
</Directory>

Alias /zm "/usr/share/zoneminder/www"
<Directory "/usr/share/zoneminder/www">
    Options -Indexes +MultiViews +FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>


I don't understand what is wrong..... can someone help me? I'd like to use zmNinja, but until api work, I can't :( :(

P.S.
All web interface seems works like a charm

If you are getting a URL error, check your apache log files and see what apache thinks
is the problem. Then you can assess if it is permissions, paths, or a zoneminder issue.

In apache's log file there's only message reported in response page...
Can someone show me how is his apache zoneminder's config file? Is it possible that mine is incomplete or wrong (for "api" directory)?
if I go to http://[server]/zm/api/ , I get this error:
Code:
Fatal error: Cannot use 'object' as class name as it is reserved in /usr/share/zoneminder/www/api/lib/Cake/Core/Object.php on line 18


It seems that CakePHP doesn't work....

I enabled debugging, it seems to work, but it does not give any real output:

API Issue SOLVED!!!
With PHP 7.2 we have to make this correction:
in apache configuration we have to add this:
Code:

# For better visibility, the following directives have been migrated from the
# default .htaccess files included with the CakePHP project.
# Parameters not set here are inherited from the parent directive above.
<Directory "/usr/share/zoneminder/www/api">
   RewriteEngine on
   RewriteRule ^$ app/webroot/ [L]
   RewriteRule (.*) app/webroot/$1 [L]
   RewriteBase /zm/api
</Directory>

<Directory "/usr/share/zoneminder/www/api/app">
   RewriteEngine on
   RewriteRule ^$ webroot/ [L]
   RewriteRule (.*) webroot/$1 [L]
   RewriteBase /zm/api
</Directory>

<Directory "/usr/share/zoneminder/www/api/app/webroot">
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
    RewriteBase /zm/api
</Directory>


we have to modifiy /usr/share/zoneminder/www/api/app/Plugin/Crud/Controller/Crud/CrudBaseObject.php (line 15)
from
Code:
abstract class CrudBaseObject extends Object implements CakeEventListener {

to
Code:
abstract class CrudBaseObject extends CakeObject implements CakeEventListener {


we have to add CakePHP-Enum-Behavior plugin (folder exists in /usr/share/zoneminder/www/api/app/Plugin, but it's empty) downloading it from here
https://github.com/asper/CakePHP-Enum-Behavior

I hope that this fixes will be added to new ebuild 8) :) :)
I'll link this post to bug #66607

Re-reading your response, I just realized that you note that Guerro is using 1.32.3...

I do not see that in the portage tree as an option (in www-misc/zoneminder or its files)... are you saying install it from the zonemidner project and test?

Thanks.

I was not suggesting any particular origin. I thought from guerro's remarks that 1.32.3 was available in the main tree. I did not check that, and see now that there is no 1.32.3 in the main tree.

I categorically discourage anyone installing outside Portage if at all available, because only the simplest of out-of-tree programs avoid making a mess. If you want to use an out-of-tree version, I strongly suggest you find or create an ebuild to wrap the version you want to use, then install that ebuild.

I would like to use an in-tree version...

again, my main concern was, and I know this is cliche (I have been a sysadmin for many decades), that 'it was working fine" and then I did an emerge --sync
and then an emerge -uDU --with-bdeps=y @world and then the only thing that breaks was zoneminder.

I wonder why no one else noticed this (e.g. is this an isolated issue)?

Thanks.

To answer that, we would need to know exactly what was changed, trace down exactly how it now dies, or both. If I were to guess, I would say that Zoneminder was doing something that is not technically legal, but happened to work with your old package setup. When you upgraded, you switched to a package which no longer allows the technically invalid operation.

The oubliette overlay has a working zoneminder-1.32.3. From what I can tell, there is no current zoneminder maintaner for the current tree so an overlay my be your best bet.
