Compile failure

Post by garlicbulb » Thu Nov 14, 2013 8:43 pm

I am trying to upgrade my ZM 1.25.0 system running on CentOS 5.10

I got the latest tar, did the cmakecacheimport.sh and cmake.

Make returns

[ 1%] Building CXX object src/CMakeFiles/zm.dir/zm_box.cpp.o
/usr/include/bits/mathcalls.h:310: error: declaration of ‘double round(double) throw ()’ throws different exceptions
/root/other/ZoneMinder-1.26.4/src/zm.h:29: error: from previous declaration ‘double round(double)’
make[2]: *** [src/CMakeFiles/zm.dir/zm_box.cpp.o] Error 1
make[1]: *** [src/CMakeFiles/zm.dir/all] Error 2
make: *** [all] Error 2

Any ideas?

Hi,

This is because zm includes its own version of round() for old systems that do not have the round() function.
It seems the detection fails to see you already have round() and a conflict arises.
You can work around it by adding -DHAVE_DECL_ROUND=1 to your cmake command line.
I will try to get this fixed in 1.26.5. Thank you for reporting.

Thanks! That change helped a bit. The make got further. Now at

Hi,

You probably need to update your ffmpeg.

In my previous install (1.25.0), I used

--with-ffmpeg=/usr/local/share/ffmpeg CPPFLAGS=-D__STDC_CONSTANT_MACROS

Is there a way to set those parameters with cmake?

Hi,

The parameter in the CPPFLAGS is not needed anymore, it's included internally.
For the ffmpeg prefix, you can use export CMAKE_PREFIX_PATH="/usr/local/share/ffmpeg" but sadly this is broken on v1.26.4, you need ZoneMinder from git for this to work:
https://github.com/ZoneMinder/ZoneMinder/tarball/master

Or you can install using autotools, just like you installed 1.25.0.
