MultiCol-SLAM
ThirdParty Dependencies：
修改编译脚本：
echo "Configuring and building Thirdparty/opencv ..." cd ThirdParty/opencv-3.1.0 mkdir build cd build cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake make -j4 make install cd ../../../ echo "Configuring and building Thirdparty/DBoW2 ..." cd ThirdParty/DBoW2 mkdir build cd build cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake make -j cd ../../ echo "Configuring and building Thirdparty/g2o ..." EIGEN3_INCLUDE_DIR=$(pwd)/Eigen export EIGEN3_INCLUDE_DIR cd g2o mkdir build cd build cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake make echo "Configuring and building Thirdparty/opengv ..." cd ../../OpenGV mkdir build cd build cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake make -j2 echo "Configuring and building MultiCol-SLAM ..." cd ../../../ echo $(pwd) mkdir build cd build #cmake .. -DCMAKE_BUILD_TYPE=Debug cmake .. -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake make -j2
开始编译首先source
source /opt/android-ndk-r21b-linux-x86_64/environment-setup-aarch64-android-linux
Pangolin：在android 不使用Pangolin不显示，所以用不编译
OpenCV 3：NDK中没有opencv，需要把opencv 源码放入第三方依赖，编译问题：
MultiCol-SLAM/ThirdParty/opencv-3.1.0/3rdparty/libpng/pngrutil.c:3943: undefined reference to `png_init_filter_functions_neon'
找不到png_init_filter_functions_neon实现。android NDK不支持PNG_ARM_NEON加速
修改代码如下：pngpriv.h line:128
# if (defined(__ARM_NEON__) || defined(__ARM_NEON)) && 改成=====================> # if defined(PNG_ARM_NEON) && (defined(__ARM_NEON__) || defined(__ARM_NEON)) &&
DBoW2 ：
CMake Error at CMakeLists.txt:33 (find_package):
find opencv package 失败，NDK中没有install opencv 所以失败，CMakeLists需要手动添加include和lib路径：
clang++: error: the clang compiler does not support '-march=native'
不支持编译标签 -march=native，CMakeLists删除-march=native
MultiCol-SLAM/ThirdParty/DBoW2/DBoW2/FORB.cpp:19:10: fatal error: 'stdint-gcc.h' file not found
找不到stdint-gcc.h头文件，改成stdint.h

链接错误，大部分的opencv库都是用了，所以需要把所有opencv 和opencv的第三方库都加进来，由于链接是用顺序的，依赖库放在后面，如opencv_highgui依赖 opencv_imgproc 依赖opencv_core，被依赖库 opencv_core放在最后。

openmp:
在执行时，找不到openmp链接，下载对应版本的src编译,我用的是android 9.0 所以使用如下链接下载源码：https://releases.llvm.org/9.0.0/openmp-9.0.0.src.tar.xz
