I want to find facial feature points using flandmark library. But I get this coimpilation error.

I want to find facial feature points using flandmark library. But I get this coimpilation error.

As instructed i tried to compile flandmark_compilemex.m

After compiling it shows the following error.

Warning: MEX could not find the library "flandmark_static" specified with -l option. MEX looked for a file with one of the names: flandmark_static.lib libflandmark_static.lib MEX looked for the library in the following directories: C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\LIB\amd64 C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\ATLMFC\LIB\amd64 C:\Program Files (x86)\Windows Kits\8.0\lib\win8\um\x64 C:\Program Files\MATLAB\R2013b\extern\lib\win64 C:\Program Files (x86)\Microsoft Visual Studio\VC98\mfc\lib C:\Program Files (x86)\Microsoft Visual Studio\VC98\lib C:\Program Files\MATLAB\R2013b\extern\lib\win64\microsoft ../bin7/libflandmark/Release

Error in flandmark_compilemex (line 79) eval(['mex -O -largeArrayDims ./mex/flandmark_detector_mex.cpp -I../libflandmark/' include libflandmark cvlibs ' -output ../matlab_toolbox/mex/flandmark_detector']);

I don't know how to compile the library files "flandmark_static" in matlab. Anyone please suggest me step by step installation of the library.

You have to compile flandmarks separately to get the flandmarks static library. Download the flandmarks package on the website, then use cmake to create an appropriate project for your platform and build environment. Note that you will need at least a C++ compiler to compile the library, how to do that exactly depends on your platform (you seem to use Windows thus using Visual Studio is probably the easiest solution).

For details check out the INSTALL file in the flandmarks repo: https://github.com/uricamic/flandmark/blob/master/INSTALL

Can you tell me the steps to compile the flandmark using cmake 2.8.12.

[Revathy Prabhu]

CMake Error: CMake was unable to find a build program corresponding to "Visual Studio 12 Win64". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: Could not find cmake module file: C:/opencv/build/flandmark-master/libflandmark/CMakeFiles/2.8.12.2/CMakeCCompiler.cmake CMake Error: Could not find cmake module file: C:/opencv/build/flandmark-master/libflandmark/CMakeFiles/2.8.12.2/CMakeCXXCompiler.cmake Configuring incomplete, errors occurred!

I get this error.
