ZoneMinder Forums

Hi all,
Following the Centos Wiki guide & have hit a wall. I have installed ffmpeg 0.6.3. Done the 'make instal'l & 'make install-libs'. But when I come to 'make' zoneminder I get the following barf:

[root@zm1 ZoneMinder-1.24.4]# make

How do I make it work ??

Do I need to use --with-ffmpeg=<path to ffmpeg root> - but I don't know where the ffmpeg has installed itself - trying to find it now...
Is there something I should know about ?

Thanks in advance,

Mike.

What does configure have to say about those headers? It should display if/where it has found them as it runs. The results should also be present (in a more verbose) form in config.log.

Hi thanks for getting back,
I have just done a find for 'ffmpeg' & seems the root is /usr/local/share/ffmpeg. Tried adding ' --with-ffmpeg=/usr/local/share/ffmpeg' to the ./configure line but still the same output.

When you ask "What does configure have to say about those headers?" do you mean 'avutils.h' , 'avcodec.h' for example ??

Not sure which file names are the headers ?

Thanks again,

Mike.

OK so I did a search for the word 'header' in config.log & here is I think what you are looking for ?

configure:7631: checking libavutil/avutil.h presence
configure:7631: g++ -E -I/usr/local/share/ffmpeg/include conftest.cpp
configure:7631: $? = 0
configure:7631: result: yes
configure:7631: WARNING: libavutil/avutil.h: present but cannot be compiled
configure:7631: WARNING: libavutil/avutil.h: check for missing prerequisite headers?
configure:7631: WARNING: libavutil/avutil.h: see the Autoconf documentation
configure:7631: WARNING: libavutil/avutil.h: section "Present But Cannot Be Compiled"
configure:7631: WARNING: libavutil/avutil.h: proceeding with the compiler's result
configure:7631: checking for libavutil/avutil.h
configure:7631: result: no

This seems to mean to me that the ffmpeg headers can't be found ? I thought I installed them when I did installed ffmpeg - 'make install-libs' as per the WiKi?
Does this post explain what I have to do perhaps? http://kb.bobcares.com/?View=entry&EntryID=252

Thanks,
Mike.

Ok tried the following & still no joy.

ffmpeg configured with:
./configure --enable-shared --enable-postproc --enable-swscale --enable-gpl

ZoneMinder-1.24.4 configured with:
./configure --with-webdir=/var/www/html/zm --with-cgidir=/var/www/cgi-bin --with-ffmpeg=/usr/local/share/ffmpeg --with-extralibs="-L/usr/local/include/libavutil -L/usr/local/include/libavcodec -L/usr/local/include/libavformat -L/usr/local/include/libswscale"

I can't seem to get the thing to build - I have trawled the web & forums & whilst there have been other instances of ' present but cannot be compiled' issues I can't seem to get any of the solutions to work for me. I have pointed ZM to the locations of the supposed missing headers but the result is always the same.
Maybe the clue is 'WARNING: libavutil/avutil.h: section "Present But Cannot Be Compiled" ' ?? I don't know what this means the headers do indeed seem to be there - at least files that match those listed in the errors such as 'avutil.h' - I assume these are the header files ? If so why don't they compile?
Or am I doing something daft in my frustration?

I don't understand - the Wiki makes it look so easy

Lastly if & when I get this to work I'd like to update that Wiki with my experience so others don't have to go through all this nonsence as well!

Mike.

Add CPPFLAGS="-D__STDC_CONSTANT_MACROS" to the end of the ./configure line for zoneminder.

The Wiki states:
Now we need to make sure we use the lasted "tested" version of "ffmpeg".

What is the latest "tested" version of "ffmpeg" ?

Thanks,

Mike.

Ahh, at last it works. Thanks for that. I notice that 'CPPFLAGS="-D__STDC_CONSTANT_MACROS" ' is listed as an option on the Centos Wiki but it says it is only for use on Centos 5.5 64-bit systems. Mine is a Centos 5.6 32-bit system.

So I'll now have to find out how to edit the Wiki to add that choise bit of information (that the above flag is needed for 32-bit Centos as well as 64) ....

But for now it's on with the Wiki & lets see if I can get this thing fired up.

Many thanks again, feel much better now... Hope nothing else comes up
Mike.
