Somehow your ncnn installation isn't correct, or your cmake has an error. Follow the steps in the manual and try to compile the project first with code::blocks and this repo. This should go right in one go. Then you can create your cmake from the project file. In the cmake you send me I see that you are calling MachineIndependent.a, something that doesn't happen in the original.

[gnajaganathan]

I build the project using code::blocks. Its built successfully. In CMake, i linked the (libncnn.a,libglslang.a,libSPIRV.a,libMachineIndependent.a,libOGLCompiler.a,libOSDependent.a,libGenericCodeGen.a) and libvulkan.so files in CMakeLists.txt

[Qengineering]

Are you still getting an error message? Look in the FaceRecognition.cbp file with a text editor In addition to the correct list of files to link, you will also find many options defined. These are also crucial for a successful build. Study this file and see if you can translate it into a cmake file. After all, Code::blocks uses the same gcc compiler as cmake.

[gnajaganathan]

I changed order of the library files in linker setting in the Code::block project build options.I can able to reproduce the issue. Original library linking order is libncnn.a ,libglslang.a,libSPIRV.a,libMachineIndependent.a,libOGLCompiler.a,libOSDependent.a,libGenericCodeGen.a,libvulkan.so.

In Code::Block, If i run command or Ctrl+F10 face recognition is working fine. But when i execute same file from the terminal window, i got error.

[Qengineering]

This error has to do with the location of the required models. Running from your current parent folder ..../bin/Debug, you will need a set of folders holding the deep learning models. They must located at .../bin/Debug/models/ etc.

[gnajaganathan]

It is working now.
