OSX Installation Instructions

[freshnewegg]

Hi, wanted to leave an unofficial guide on how i got this working on OSX without CUDA. You can use this method if you just want to do feature extraction and SFM on Meshroom. This just builds on some of the debugging other folks have done over time.

1) Clone the repo and checkout v2.3.0. I know https://github.com/alicevision/meshroom/wiki/MacOS says you want 2.2.0 but there's some bug with it . Also, You don't need ryan baumann's work on CUDA if you're just playing with photogrammetry or don't have a GPU.

2) Follow the direction of the OSX section in https://github.com/alicevision/AliceVision/blob/develop/INSTALL.md & do mkdir build && cd build 3) brew install needed dependencies brew install ceres-solver brew install flann brew install eigen brew install openexr brew install openimageio

4)update alicevision submodules git submodule update -i

• DO NOT install OpenMesh or MeshSDFilter as these come with AliceVision and seem to have a custom fork. Installing these from brew will likely break your build 5) Run this make command

cmake -DCeres_DIR:PATH=/usr/local/Cellar/ceres-solver/1.14.0_13/lib/cmake/Ceres/ -DFLANN_INCLUDE_DIR_HINTS:PATH=/usr/local/Cellar/flann/1.9.1_9/include/ - DCMAKE_MODULE_PATH:PATH=/usr/local/Cellar/eigen/3.3.8_1/share/cmake/Modules/ -DOPENEXR_HOME:PATH=/usr/local/Cellar/openexr/2.5.3/ -DOPENIMAGEIO_LIBRARY_DIR_HINTS:PATH=/usr/local/Cellar/openimageio/2.1.18_1/lib/ -DOPENIMAGEIO_INCLUDE_DIR:PATH=/usr/local/Cellar/openimageio/2.2.7_1/include/ -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DOpenMP_CXX_FLAGS="-Xpreprocessor -fopenmp -lomp -L$(brew --prefix libomp)/lib -I$(brew --prefix libomp)/include" -DOpenMP_CXX_LIB_NAMES="omp" -DOpenMP_omp_LIBRARY=$(brew --prefix libomp)/lib/libomp.a -DCMAKE_SHARED_LINKER_FLAGS="-lomp" -DCMAKE_EXE_LINKER_FLAGS="-lomp" -DALICEVISION_USE_CUDA=OFF ../AliceVision/ -G "Unix Makefiles"

key flags to note: -DALICEVISION_USE_CUDA=OFF -> turns CUDA off so you can avoid a Nvidia graphics card if you don't have one -DCMAKE_SHARED_LINKER_FLAGS="-lomp" -> you may or may not need this. If you see any Undefined symbols for architecture x86_64 with omp then it's most likely this -DCMAKE_EXE_LINKER_FLAGS="-lomp" -> you may or may not need this. If you see any Undefined symbols for architecture x86_64 with omp then it's most likely this

6) you should then do make. Double check the files are in /usr/local/bin and in your path i.e should return something.

7) Use meshroom version v2019.2.0 as suggested in https://github.com/alicevision/meshroom/wiki/MacOS

happy building!
