Línea de trabajo

Descripción

Go to : cmake/FindDependencies.cmake

# Manually define the paths to your HOME-built OIIO
set(OPENIMAGEIO_LIBRARIES 
    "/home/user/oiio/build/lib/libOpenImageIO.so"
    "/home/user/oiio/build/lib/libOpenImageIO_Util.so"
)
set(OPENIMAGEIO_INCLUDE_DIRS "/home/user/oiio/build/include")

# Create/Update the target COLMAP expects
if(TARGET OpenImageIO::OpenImageIO)
    set_target_properties(OpenImageIO::OpenImageIO PROPERTIES
        INTERFACE_INCLUDE_DIRECTORIES "${OPENIMAGEIO_INCLUDE_DIRS}"
        IMPORTED_LOCATION "/home/user/oiio/build/lib/libOpenImageIO.so"
        INTERFACE_LINK_LIBRARIES "/home/user/oiio/build/lib/libOpenImageIO_Util.so"
    )
else()
    add_library(OpenImageIO::OpenImageIO UNKNOWN IMPORTED)
    set_target_properties(OpenImageIO::OpenImageIO PROPERTIES
        INTERFACE_INCLUDE_DIRECTORIES "${OPENIMAGEIO_INCLUDE_DIRS}"
        IMPORTED_LOCATION "/home/user/oiio/build/lib/libOpenImageIO.so"
        INTERFACE_LINK_LIBRARIES "/home/user/oiio/build/lib/libOpenImageIO_Util.so"
    )
endif()

cd ~/colmap4.0/colmap-4.0.2/build
rm -rf *

Reconfigure with our anti-crash flags + specific GCC 11

cmake .. -GNinja
-DCMAKE_C_COMPILER=/usr/bin/gcc-11
-DCMAKE_CXX_COMPILER=/usr/bin/g++-11
-DCMAKE_BUILD_TYPE=Release
-DCMAKE_CUDA_ARCHITECTURES="89"
-DCMAKE_CXX_FLAGS_RELEASE="-O2 -fno-tree-slp-vectorize"
-DCMAKE_C_FLAGS_RELEASE="-O2 -fno-tree-slp-vectorize"

Final build

export LD_LIBRARY_PATH=/home/user/oiio/build/lib:$LD_LIBRARY_PATH
ninja -j4

echo 'export LD_LIBRARY_PATH=/home/user/oiio/build/lib:/home/user/onnxruntime-linux-x64-gpu-1.24.4/lib:$LD_LIBRARY_PATH' >> ~/.bashrc

Notes:
In Ubuntu20, libOpenImageIO-dev doesnt come with .cmake files - i installed OpenImageIo, OpenEXR, Imath etc from source

Go to your OIIO source directory

cd ~/oiio
rm -rf build
mkdir build && cd build

Force OIIO to use GCC 11

export CC=/usr/bin/gcc-11
export CXX=/usr/bin/g++-11

cmake ..
-DCMAKE_INSTALL_PREFIX=/home/user/oiio/build/install
-DUSE_PYTHON=OFF
-DSTOP_ON_WARNING=OFF

make -j$(nproc)

Make this permanent in your .bashrc
