I check the liblzma is installed.

liblzma-dev is already the newest version. liblzma5 is already the newest version.

the CMakeError.log /usr/bin/cc -DCHECK_FUNCTION_EXISTS=pthread_create -L/usr/lib -L/usr/local/lib CMakeFiles/cmTryCompileExec1251144548.dir/CheckFunctionExists.c.o -o cmTryCompileExec1251144548 -rdynamic -lpthreads /usr/bin/ld: cannot find -lpthreads collect2: error: ld returned 1 exit status CMakeFiles/cmTryCompileExec1251144548.dir/build.make:88: recipe for target 'cmTryCompileExec1251144548' failed make[1]: * [cmTryCompileExec1251144548] Error 1 make[1]: Leaving directory '/home/dzh/Documents/video_segment/seg_tree_sample/CMakeFiles/CMakeTmp' Makefile:114: recipe for target 'cmTryCompileExec1251144548/fast' failed make: * [cmTryCompileExec1251144548/fast] Error 2

and i check my libthread too. it works well.

http://stackoverflow.com/questions/24813827/cmake-failing-to-detect-pthreads-due-to-warnings says it's i bug of cmake. i follow his suggestion, no magic happen.

i doubt its should be specifiy in CMakeList.txt

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -pthread") set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread") set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -pthread")

but still don't works.

do i missing something??

Have a look at #9 for a starting point.
