Could not find OpenBLAS

[Shaunlipy]

I am compiling it on my Jetson Nano. I have openblas installed at:

libopenblas.so.0 (libc6,AArch64) => /usr/lib/aarch64-linux-gnu/libopenblas.so.0 libopenblas.so (libc6,AArch64) => /usr/lib/aarch64-linux-gnu/libopenblas.so

But when I execute the "Cmake -D ..."

I still got error:

-- Could not find OpenBLAS include, defaulting to using OpenFace vended ones -- Could not find OpenBLAS lib. Turning OpenBLAS_FOUND off CMake Error at cmake/modules/FindOpenBLAS.cmake:103 (MESSAGE): Could not find OpenBLAS Call Stack (most recent call first): CMakeLists.txt:14 (find_package)

Should I link the openblas somehow?

Compile openblas from source. The package of Ubuntu repos do not have lapacke.h

Small addition to @sziraqui's suggestion (by the way it works for me), to build OpenFace on ARM you will also need to comment section with x86 SIMD options in CMakeLists.txt:

if (${CMAKE_CXX_COMPILER_ID} STREQUAL "GNU")
    execute_process(COMMAND ${CMAKE_CXX_COMPILER} -dumpversion OUTPUT_VARIABLE GCC_VERSION)
    if (GCC_VERSION VERSION_LESS 4.7)
        set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x -msse -msse2 -msse3")
    else ()
        set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -msse -msse2 -msse3")
    endif ()
else ()
    set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -msse -msse2 -msse3")
endif ()

An addition to the original question and @sziraqui ' comment

Ive been successful with installing based on Ubuntu repros

sudo apt-get install liblapack-dev liblapacke-dev libopenblas-dev # not sure this is necessary

And then in cmake/modules/FindOpenBLAS.cmake add the two lines

/usr/include/aarch64-linux-gnu/

and

/usr/lib/aarch64-linux-gnu/

in the include and lib search paths.

As a side note. I got errors with dlib-19.13:

...
undefined reference to `pthread_create'
...
cannot find -lpthreads
...
undefined reference to `sgesv'
...

But I was successful with dlib-19.22. And got a working OpenFace installation after removing the arguments for SSE SIMD as suggested by pi-null-meazon

I encountered the following problem when compiling the project, I would like to ask how to solve it ah

Have a look into "https://github.com/TadasBaltrusaitis/OpenFace/issues/479", same errors reported when compiling on a Jetson device (no SSE CPU instructions?)
