centos安装colmap
一、安装依赖

sudo yum install \gflags-devel \glog-devel \glew-devel \atlas \atlas-devel \lapack-devel \blas-devel \flann-devel \lz4-devel \sqlite-devel \metis-devel \qt5-qtbase-devel

二、编译安装colmap

git clone https://github.com/colmap/colmap.git
cd colmap
git checkout dev
mkdir build
cd build
cmake .. 
sudo make install 

报错：CMake Error at /usr/lib64/cmake/Ceres/CeresConfig.cmake:89
安装：cere-solver 1.14.0

wget ceres-solver.org/ceres-solver-1.14.0.tar.gz
tar xvf ceres-solver-1.14.0.tar.gz
cd ceres-solver-1.14.0
mkdir build
cd build
cmake ..
make -j4
sudo make install

重新cmake ..，报错Could not find FreeImage
安装：FreeImage

git clone https://github.com/leapmotion/FreeImage
cd FreeImage
make
sudo make install
make clean

遇到报错：error: narrowing conversion of ‘128’ from ‘int’ to ‘signed char’ inside { } [-Wnarrowing]
解决：打开FreeImage/Makefile.gnu，30行添加CXXFLAGS += -Wno-narrowing，编译成功

编译colmap期间如果遇到Could NOT find XXX，用sudo yum search xxx 搜索相关的库，如果有就用yum安装，没有就从源码编译安装。

继续编译colmap，遇到报错：The CUDA compiler identification is unknown colmap
这里系统使用cuda11.3
编译命令改成：

cmake .. -D CMAKE_CUDA_ARCHITECTURES='70' -D CMAKE_CUDA_COMPILER="/usr/local/cuda/bin/nvcc"

CUDA问题解决，遇到报错

Cannot generate a safe linker search path for target colmap_exe becausefiles in some directories may conflict with libraries in implicitdirectories:link library [libglog.so] in /usr/lib64 may be hidden by files in:/home/liaobaoxin.lbx/miniconda3/liblink library [liblz4.so] in /usr/lib64 may be hidden by files in:/home/liaobaoxin.lbx/miniconda3/liblink library [libsqlite3.so] in /usr/lib64 may be hidden by files in:/home/liaobaoxin.lbx/miniconda3/lib

提示我们一些so跟miniconda3/lib中的so冲突，先把miniconda3目录重命名，编译colmap，然后再改回来

报错 Could NOT find Boost 待解决
