make: *** [all] Error 2 Solved

I had the same problem but then came across this page: https://blenderartists.org/t/makefile-160-recipe-for-target-all-failed/682149

Briefly, this is what I did:

Make sure you are in the right directory. In my case (Trying to install opencv on Raspberry Pi): ~/opencv_build/opencv/build $ Run the following Codes

make -j2 BUILD_CMAKE_ARGS="-U *SNDFILE* -U *PYTHON* -U *BOOST* -U *Boost* -U *OPENCOLORIO* -U *OPENEXR* -U *OPENIMAGEIO* -U *LLVM* -U *CYCLES* -U *OPENSUBDIV* -U *OPENVDB* -U *COLLADA* -U *FFMPEG* -U *ALEMBIC* -D WITH_CODEC_SNDFILE=ON -D PYTHON_VERSION=3.5 -D WITH_OPENCOLORIO=ON -D OPENCOLORIO_ROOT_DIR=/opt/lib/ocio -D WITH_OPENIMAGEIO=ON -D OPENIMAGEIO_ROOT_DIR=/opt/lib/oiio -D WITH_CYCLES_OSL=ON -D WITH_LLVM=ON -D LLVM_VERSION=3.4 -D CYCLES_OSL=/opt/lib/osl -D LLVM_ROOT_DIR=/opt/lib/llvm -D LLVM_STATIC=ON -D WITH_OPENSUBDIV=ON -D OPENSUBDIV_ROOT_DIR=/opt/lib/osd -D WITH_OPENVDB=ON -D WITH_OPENVDB_BLOSC=ON -D WITH_OPENCOLLADA=ON -D WITH_ALEMBIC=ON -D ALEMBIC_ROOT_DIR=/opt/lib/alembic -D WITH_CODEC_FFMPEG=ON -D FFMPEG_LIBRARIES='avformat;avcodec;avutil;avdevice;swscale;swresample;lzma;rt;theoradec;theora;theoraenc;vorbisenc;vorbisfile;vorbis;ogg;xvidcore;vpx;mp3lame;x264;openjpeg;openjpeg_JPWL'" After, run this:

WITH_ALEMBIC=ON I have no idea what this does, but it just worked for me.

ALEMBIC_ROOT_DIR=/opt/lib/alembic Finally,

make clean

rm -rf ../build_linux I hope someone finds it helpful:)
