ZoneMinder Forums

I'm having trouble getting past the configuration of zoneminder on this system.

here is the command I'm issuing:

./configure --with-webdir=/var/www/html --with-cgidir=/var/www/cgi

here is the error that I receive:

checking for mysql_init in -lmysqlclient... no
configure: error: zm requires libmysqlclient.a

any ideas?

You need to install the "dev" packages of mysql...

I had already done that...

[root@someworkstation ZoneMinder-1.24.2]# yum install mysql-devel
Loaded plugins: rhnplugin, security
Setting up Install Process
Package mysql-devel-5.0.77-3.el5.x86_64 already installed and latest version
Package mysql-devel-5.0.77-3.el5.i386 already installed and latest version
Nothing to do

I'm thinking you need to specify the "--with-libarch=lib64" configure parameter (libmysqlclient.a can be found under /usr/lib64 not /usr/lib on 64bit systems).

If you want to use a known good set of parameters, just copy and paste these:
Works great on my 64bit CentOS 5.4 platform. I'd expect your RHEL 5.4 system to compile pretty close to CentOS 5.4.

It probably goes w/o saying, but verify the ffmpeg path is correct for your system, and of course change the march and mtune parameters to match your cpu architecture.

I'm jumping ahead here, but if you run into any further issues regarding missing libraries, you would probably benefit from reading the install guide for CentOS if you have not already:
http://www.zoneminder.com/wiki/index.php/CentOS

It will give you an idea of what RPM packages you will need.

Well I got it installed thanks!

now I get a black screen when viewing the camera
searched for the problem and a lot of people suffer this

the configure scripted that worked:

Are you using a local capture card?

If so, check your permissions on /dev/videoX where "X" is the number of the video device that points to your capture card. Either chmod /dev/videoX or I think zmfix can fix it for you (search the forums for proper syntax).

If this does not resolve the issue, then test your camera using xawtv at a resolution of 320x240. Report you results. Doing so will help identify the root cause of the problem.

sorry guess I should have said what camera...

its an IP camera.. more specifically an AXIS 2130R PTZ camera.

I have tried all the presets and no luck

I just took a second look at the the output you posted.

You've identified kernel.shmall (and that looks ok), but what is kernel.shmmax set to? One usually has to increase the shmmax on a default system to avoid shared memory errors.

I've got mine set to 268435456 (256MB). This number will vary, depending on your ring buffer and resolution.

mine is set to:

68719476736

should I try changing this?

I doubt that value will work at all since it almost certainly exceeds the amount of physical memory you have in the machine.

Try the value I mentioned previously. If you are setting this via your sysctl.conf then remember you will need to reboot for the new setting to take effect.

Admittedly, the value of 256MB is probably more than you need, but it should work. If you are interested, there are plenty of threads in this forum that discuss how to calculate a value for your system.

ok. I rebooted and now my shmmax reports

268435456

however I still have a black screen when trying to view the camera.. output of the logs:

I'm wondering if the issue is not shared memory per say, but rather an inability to get an image from the camera.

I noticed that zmupdate was not able to contact www.zoneminder.com could simply be an unrelated dns problem, but just in case let me ask the obvious... can you successfully open a web browser and point it to the camera's ip address?

What are your camera settings... particularly the info on the "source" and "buffers" tabs?

yes I can see the camera fine from its internal web server

The source tab:
Remote Protocol HTTP
Remote Method Simple
Remote Host Name [The actual IP address]
Remote Host Port 80
Remote Host Path /axis-cgi/jpg/image.cgi?resolution=320x240
Remote Image Colours 24 bit colour
Capture Width 320
Capture Height 240

Buffers
Image Buffer Size (frames) 40
Warmup Frames 25
Pre Event Image Count 10
Post Event Image Count 10
Stream Replay Image Buffer 1000
Alarm Frame Count 1

Have you tried using mapped memory instead? Add --enable-mmap to the configure line.
