• Solution

 

- CONFIGURATION

 

cd ~/workspace_julita/Pangolin
rm -rf build
rm -f CMakeCache.txt
mkdir build
cd build

cmake .. \
  -DCMAKE_BUILD_TYPE=Release \
  -DBUILD_SHARED_LIBS=ON \
  -DBUILD_PANGOLIN_PYTHON=OFF \
  -DBUILD_PANGOLIN_VIDEO=OFF \
  -DBUILD_PANGOLIN_FFMPEG=OFF \
  -DBUILD_PANGOLIN_OPENNI=OFF \
  -DBUILD_PANGOLIN_OPENNI2=OFF

cmake -LAH . | grep -E "BUILD_PANGOLIN_(PYTHON|VIDEO|FFMPEG|OPENNI)"

 

Then, You MUST see:

BUILD_PANGOLIN_PYTHON:BOOL=OFF
BUILD_PANGOLIN_VIDEO:BOOL=OFF
BUILD_PANGOLIN_FFMPEG:BOOL=OFF
BUILD_PANGOLIN_OPENNI:BOOL=OFF
BUILD_PANGOLIN_OPENNI2:BOOL=OFF

 

Then, Build Pangolin

make -j$(nproc)

 

Then, Install Pangolin

sudo make install
sudo ldconfig

 

Then, FINAL CHECK

sudo find /usr/local -name "libpangolin.so*"

 

Expected:

/usr/local/lib/libpangolin.so

 

When this appears, Pangolin is finally done.
