ZoneMinder Forums

Hello I have installed CentOS5 and I believe all the dependencies needed and also ffmpeg.

Trying to install ZM 1.25.0

I use the configure line:

./configure --with-webdir=/var/www/html/zm --with-cgidir=/var/www/cgi-bin --with-ffmpeg=/usr/local/share/ffmpeg

And when I try to "make" I receive:

make all-recursive
make[1]: Entering directory `/ZoneMinder-1.25.0'
Making all in src
make[2]: Entering directory `/ZoneMinder-1.25.0/src'

I have tried following this walkthrough:

http://www.zoneminder.com/wiki/index.php/CentOS

With no luck... at first I had much trouble installing ffmpeg as described in that walkthrough.

When I followed that walkthrough for everything except ffmpeg (I installed that using a walkthrough on the ffmpeg site) I ran into the issue I am having now.

ffmpeg seems to be installed correctly at this point.

If anyone knows what is up or has any suggestions please let me know. Thank you.

Try adding CPPFLAGS="-D__STDC_CONSTANT_MACROS" to the end of your ./configure line

Same problem when trying to run make.

It gets a little further in the beginning but then:

Please try the following:

open term and install git and svn (subversion) if not installed
get ffmpeg via git
...
build it
cd ffmpeg
./configure --enable-gpl --enable-shared --enable-pthreads
make
make install

OK.
may be that libs are installed in /usr/local/lib !
Not in /usr/lib64 if you run 64bit.
make shure that ffmpeg libs are in ld library path!

get zoneminder via svn like discribed on its homepage.
my config string:

CXXFLAGS=-D__STDC_CONSTANT_MACROS ./configure --with-webdir=/var/www/html/public/zm --with-cgidir=/var/www/cgi-bin --with-webuser=apache --with-webgroup=apache ZM_DB_HOST=localhost ZM_DB_NAME=zm ZM_DB_USER=your_zm_user ZM_DB_PASS=your_zm_password ZM_SSL_LIB=openssl --prefix=/opt/zm --with-extralibs="-L/usr/lib64 -L/usr/lib64/mysql" --with-ffmpeg=/opt/ffmpeg/share/ffmpeg CPPFLAGS="-D__STDC_CONSTANT_MACROS"

Note: I compiled ffmpeg to /opt/ffmpeg, so take care to change "--with-ffmpeg=/opt/ffmpeg/share/ffmpeg" and your usernames etc!!!

that worked for me!
regards

Getting same result here.

RHEL 6.2 x86_64, g++=4.4.6-3

I used git to obtain ffmpeg and then compiled installed. Can run ffmpeg command with no errors.

Ideas?

I am currently using CentOS 6 with zoneminder from svn and ffmpeg from git

with zoneminder from the stable download i had no success.

with zoneminder from svn and ffmpeg from git
I had the same error as long --with-ffmpeg=..." in the zm ./configure string was not ok.
build ffmpeg with --prefix=/opt/ffmpeg
and add the libs (/opt/ffmpeg/lib) to e.g. /etc/ld.so.conf.d/ffmpeg.conf
run ldconfig

i also did:
ln -s /opt/ffmpeg/bin/* /usr/bin

then i added --with-ffmpeg=/opt/ffmpeg/share/ffmpeg in the zm configure string and it worked.

if zm fails to start after compilation and installation check if the mysql db is correctly installed:

mysql -u root -p
mysql> create database zm;
mysql> CREATE USER 'your_zm_user'@'localhost' IDENTIFIED BY 'your_zm_password_from_above';
mysql> grant CREATE, INSERT, SELECT, DELETE, UPDATE on zm.* to your_zm_user@localhost;
mysql -u root -p zm < db/zm_create.sql

Note: db/zm_create.sql is within the source tree.
type "zoneminder centos 6" in "google" to see a howto. not all steps are necessary but it helped me.

Still no joy.

I rebuilt ffmpeg with the /opt/ffmpeg prefix and still the same results.

here is my configure line:
CPPFLAGS=-D__STDC_CONSTANT_MACROS ./configure \
--with-webdir=/var/www/html/zm \
--with-cgidir=/var/www/cgi-bin \
--with-extralibs="-L/usr/lib64 -L/usr/lib64/mysql" \
--with-ffmpeg=/opt/ffmpeg/share/ffmpeg \
--with-webuser=apache \
--with-webgroup=apache \
ZM_SSL_LIB=openssl \
CPPFLAGS=-D__STDC_CONSTANT_MACROS \
CXXFLAGS="-D__STDC_CONSTANT_MACROS" \
ZM_DB_NAME=zm \
ZM_DB_USER=zmuser \
ZM_DB_PASS=zmpass \
ZM_DB_HOST=localhost

On http://www.zoneminder.com/wiki/index.php/CentOS I read the following:
->"e.g. For CentOS 5.6 64-bit with support for ffmpeg. The whole command must be executed on one line. ..."
Have you tried to remove all the backslashes in your ./configure... command?

Configure command:

CPPFLAGS=-D__STDC_CONSTANT_MACROS ./configure --with-webdir=/var/www/html/zm --with-cgidir=/var/www/cgi-bin --with-extralibs="-L/usr/lib64 -L/usr/lib64/mysql" --with-ffmpeg=/opt/ffmpeg/share/ffmpeg --with-webuser=apache --with-webgroup=apache ZM_SSL_LIB=openssl ZM_DB_NAME=zm ZM_DB_USER=zmuser ZM_DB_PASS=zmpass ZM_DB_HOST=localhost CPPFLAGS=-D__STDC_CONSTANT_MACROS CXXFLAGS="-D__STDC_CONSTANT_MACROS"

Rats, still no joy.

I tried it all on one line, no \ line continuation stuff.

I am guessing that it is something to do with the compiler version, 4.4.6-3.

From what I can tell it is not that it can't find things, but seems to be a syntax thing.

Thanks

short version: I have the same issue as flatlander & nvandal. Appears to be a 64-bit issue somewhere, but I haven't narrowed it down yet. Bottom line, ran exact same setup as tutorial (except ffmpeg to /opt) on 32-bit centos 5.8 and works like a charm so far. ZM service is running.

long version:
I'm testing Zoneminder out right so I had it loaded on a Centos 5.8 64-bit VM in virtualbox. I'm having the same issue as nvandal. Getting a ton of errors on zm_ffmpeg_camera.cpp when running 'make' exactly like those listed in his second post.

Steps taken so far:

• *Followed CentOS Tutorial with v1.25.0 (except fixing a couple of the lib names in the sym link section required to get ffmpeg running). No Change
  *Tried ffmpeg from yum (rpmforge) and update ffmpeg path in configure command. No Change
  *Tried ffmpeg compile again from git this time to /opt like Christianh suggested. No Change
  *Verified running 'yum update -y' No Change
  *Tried compiling SVN Trunk release instead of 1.25.0, same issue. No Change
  *Rebooted the system (what the hell...never know right?) No Change

ZM configure command used: My output from FFMPEG: For the hell of it, I setup a 32-bit Centos 5.8 on a new VM because I had a feeling it's something 64-bit related. I followed the guide pretty much except installed ffmpeg to /opt/ffmpeg again. Just compiled no problem and the zm service started up no problem. Haven't gone further into testing yet than starting ZM service, but figured I'd pass on what I learned first.

Working configure command used on 32-bit: So bottom line: Same process in the guide, compiles on 32-bit, but fails on 64-bit. I usually use software from repo's so I'm at a loss of what to try next. Open to any suggestions or can provide any more details if someone has an idea. I'm just going to leave the 64-bit VM there, so if anyone updates this thread with ideas/suggestions I'll give it a shot.

I'm going to move forward with testing it on 32-bit for now, and may try CentOS 6 64-bit tomorrow to see if I can get that to work. We've had some vandalism recently in our neighborhood so we are looking to get a security solution up and running ASAP to try catch the bastards!

After installing ffmpeg as described by christian I receive the following when I try to run ffmpeg:


ffmpeg: error while loading shared libraries: libavformat.so.54: cannot open shared object file: No such file or directory

I am running 32bit

My guess is you missed a step with the lib setup somewhere in the ffmpeg setup...
*Make sure you ran 'make install-libs'
*Create the file /etc/ld.so.conf.d/ffmpeg.conf that contains just "/opt/ffmpeg/lib" without quotes.
*Run ldconfig

Then try run ffmpeg again and see if it works.

I downloaded version 1.24.4 today and successfully built and installed. Tried to make 1.25 and it still fails. Is there a significant reason to try and use the 1.25?

Thanks

I ended up having to add /usr/local/lib to the /etc/ld.so.conf.d/ffmpeg.conf file.

Thanks for pointing me in the right direction.

Now to try the actual ZM install!

Same problem, I get a bunch of:
