我使用此PPA中的标头以及与camshiftdemo.c位于同一目录中的build_all.sh脚本在我的Ubuntu 10.04上构建了演示。我得到的只是Could not initialize capturing...消息。
然后我尝试使用这一行构建它（在CMake创建的构建目录中使用CMake构建演示后找到它）：
gcc -Wall -Wno-long-long -pthread -ffunction-sections -O3 -DNDEBUG -fomit-frame-pointer -O3 -ffast-math -mmmx -msse -msse2 -msse3 -DNDEBUG camshiftdemo.c -o camshiftdemo -rdynamic -ldl -lm -lpthread -lrt /usr/lib/libcv.so.2.1.0 /usr/lib/libcxcore.so.2.1.0 /usr/lib/libhighgui.so.2.1.0 /usr/lib/libml.so.2.1.0 /usr/lib/libcvaux.so.2.1.0 /usr/lib/libhighgui.so.2.1.0 /usr/lib/libcv.so.2.1.0 /usr/lib/libml.so.2.1.0 /usr/lib/libcxcore.so.2.1.0 /usr/lib/libunicap.so.2.1.8 /usr/lib/libgstbase-0.10.so.0.24.1 /usr/lib/libgstreamer-0.10.so.0.24.1 /usr/lib/libxml2.so.2.7.6 -ldl -lm -lpthread -lrt 3rdparty/lib/libopencv_lapack.a 3rdparty/lib/libzlib.a 3rdparty/lib/libflann.a
您应该将建筑目录中的“3rdparty”复制到示例目录中。
请注意，我包含了gstreamer，unicap和libxml2库。这就是我发现将两个精灵版本（一个与CMake）与/lib/ld-linux.so --list
