Hi
I'm using a Ubuntu 11.04 Desktop 64 bits.
As recommended in the Wiki documentation, I tried using -O3 in order to optimize code
The parameters are :
export CFLAGS="-march=native -O3 -pipe"
export CXXFLAGS="${CFLAGS}"
export CPPFLAGS="${CFLAGS}"
When compiling graphic components like x264 and ffmpeg, I got no problems with these options
When compiling ZoneMinder 1.24.4 I got one :
zm_rtp_source.o: In function `RtpSource::handlePacket(unsigned char const*, unsigned long)':
zm_rtp_source.cpp:(.text+0xf15): undefined reference to `ThreadData<bool>::updateValueSignal(bool)'

collect2: ld returned 1 exit status

If I change the compiler parameters as these :
export CFLAGS="-march=native -O2 -pipe"
export CXXFLAGS="${CFLAGS}"
export CPPFLAGS="${CFLAGS}"
I can compile ZoneMinder and launch it without problem
Any help appreciated
Best Regards
