編譯ceres時
could not find a configuration file for package "eigen3" that is compatible with requested version "3.3".
解決：把ceres版本調整到1.14.x

sudo apt-get install libeigen3-dev 路徑 /usr/include/eigen3/ (預設使用路徑)
原始碼編譯路徑 /usr/local/include/eigen3/ （版本是正確的，但是沒起作用）
解決
1、刪掉編譯檔案重新編譯，若不行，嘗試步驟2
2、camera_models包和vins_estimator包，cmakelists檔案加上
find_package(opencv 3.3.1 required)
message(warning "opencv_version: $")
刪掉編譯檔案重新編譯
原因：可能是opencv2.4版本和opencv3.3版本發生了衝突
編譯和執行
對於語句nsstring testobject nsdata alloc init testobject 在編譯時和執行時分別是什麼型別的物件？首先，宣告 nsstring testobject是告訴編譯器，testobject是乙個指向某個objective c物件的指標。因為不管指向的是什麼型別...
