前言

這兩天遇到了先後遇到了,
1. rosbuild_ws下面編譯通過程式碼,但是無法執行程式,無法跑資料庫的尷尬局面;
2. rosbuild_ws下面同時存在LearnVIORB和另外一個基於此的程式碼的時候,ros路徑的問題;
3. 然後rosbuild_ws徹底不工作的問題;
4. ~/.zshrc系列設定的問題;
5. 然後索性把rosbuild_ws下面的東西先拷貝出來。在catkin_ws下面編譯!
這次記錄了在這個下面編譯VIORB的過程中先後遇到的問題,記錄一下!
——————————————————————————————————————————————————————

問題一:

編譯過程中出現YOU MIXED DIFFERENT NUMERIC TYPES等等錯誤,就是說顯示的是各種看起來讓人不舒服的<>這種括號裡面亂七八糟的東西,因為之前單獨編譯ORB-SLAM的時候也遇到過,就一下子解決了
【解決辦法】
Step1:
在LearnVIORB專案下,進入到Thirdparty/g2o/g2o/solvers目錄下面:
Step2:
用vim或者gedit修改linear_solver_eigen.h檔案;
具體的修改的內容:

//1.找到下面這一行:
typedef Eigen::PermutationMatrix<Eigen::Dynamic, Eigen::Dynamic, SparseMatrix::Index> PermutationMatrix;
//2.把上面找到的這一行修改為:
typedef Eigen::PermutationMatrix<Eigen::Dynamic, Eigen::Dynamic, int> PermutationMatrix;

簡而言之,上面其實就是把<>裡面的SparseMatrix::Index換成int而已

Step3:
儲存退出重新編譯。

然後在編譯的過程中我又遇到了這樣的問題:
————————————————————————————————————————————————————————

問題二:

OpenCV版本的問題,LearnVIORB 提供的是OpenCV 2.x.x的版本,具體的我忘記了,
但是在編譯的過程中總是走到開始編譯 VIO部分60%部分的時候報錯然後就失敗了!!!
【解決辦法】
這個比較簡單,不一一列舉了!
簡單的說就是把 LearnVIORB下面的 CMakeList.txt和Examples/ROS/VIO_ORB下面的CMakeList.txt中的find package()都改成相應的版本,順便還要在之前新增:
set( OpenCV_DIR "/usr/local/opencv3.2.0/share/OpenCV")
這裡我以自己安裝opencv3的地址為例,記住是每個CMakeListx.txt都要進行這樣的操作~

好了,這下VIORB的VIO的部分能夠編譯到100%了,但是又出現瞭如下的新的問題:
——————————————————————————————————————————————————————

問題三:

報錯資訊:
基本就是各種undefined reference to XXX
看得我就很生氣!很生氣!

【解決辦法】

嘗試1:

參考https://github.com/ANYbotics/grid_map/issues/159
採取方式:把gcc的版本從4.8切換到5.4
結果:VIO只走到33%,還不如剛剛了,出現了更多的undefined的東西,而且pangolin也不對經了!
難道我剛剛加的東西有問題???

嘗試2:

採取措施:在嘗試1的基礎上,把CMakeList.txt中的我新增的部分,include_directories()裡面的東西取消掉
結果:VIO的編譯達到了100%,說明還是有效果的,但是還是出現瞭如下報錯資訊:
基本上看起來都是第三方庫的原因了,說明還是有進步的,起碼有繼續一個一個修改的慾望了!明天繼續!
對哦,我懷疑現在的問題是c++11標準的問題,明天該CMakeLists.txt中的c++11標準部分,直接啟用這個試試 !

嘗試3:

採取措施:CMakeLists.txt中的c++11標準直接進行,不搞那些判斷的語句了!註釋掉試試!
把之前的註釋掉!,只保留
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
結果:失敗,但是VIO的編譯還是能夠走到100%的,心塞塞

報錯和剛剛一毛一樣,說明這樣的修改無效!
繼續新的嘗試~~

嘗試4:

採取措施:
(猜測還是OpenCV的問題???)
Step1:修改set(CMAKE_CXXFLAGS)
Step2:set( CMAKE_CXX_FLAGS "-std=c++11 -O3" )
Step3:進入Thirdparty中,把BDOW和G2O下面的build都刪掉然後重新編譯!

結果:

分析:關於BOW和g2o的undefined的報錯都沒有了,說明採取的措施的第三步奏效了,
那麼也就是說Pangolin可能需要重新編譯一下???

再進行嘗試:

嘗試5:

回頭看了一下,發現關於Pangolin的報錯是從我把gcc/g++的版本從4.8切換到5.4之後才產生的,所以,我是不是要用gcc/g++5.4的形態對pangolin重新進行一次編譯?
採取措施:恢復之前的註釋掉的關於c++11標準的東西再編譯一遍!(和預想的一樣,派出了c++11標準的么蛾子!)
想法:set()一下Pangolin的標頭檔案的路徑!應該就是這裡的問題了吧!

// --在CMakeLists.txt中新增一下
set( Pangolin_DIR "/usr/local/include/pangolin")

結果:編譯都無法通過,說明我新增的是錯的,對cmake一無所知!!!
重新新增一下路徑
set(pangolin/display)
結果:也不行,VIO的編譯通過不了
繼續嘗試:
set( Pangolin_DIR “/home/hri/ThirdParty/Pangolin-master/CMakeModules”)

結果:還是失敗!

我覺得因該是得重新裝Pangolin了

嘗試6:

分析:網上搜了一下關於undefined reference的報錯的帖子,裡面都提到了gcc/g++的相關東西,我就在想是不是因為之前環境都是用gcc/g++4.8來弄的,但是這次的ros環境下的東西我又都是在5.4版本下面弄得(前面說了4.8的時候ros上會報錯很多),那麼就打算重新安裝一下pangolin, 在gcc/g++5.4版本下編譯!
採取措施:
刪掉之前的Pangolin的編譯包,/usr/下面那些關於上個版本pangolin的餘孽殘黨不用去管,重新編譯的時候會覆蓋掉之前那些東西的!
具體方法:
Pangolin的github地址:
https://github.com/stevenlovegrove/Pangolin
下載後正常編譯就好了!

然後再編譯VIORB的程式碼,順利通過如下:

好了!開始在這個上面做點工作吧,希望我可以!

___________________________分割線_________________________________

接下來就是把程式跑起來:
按照github上的東西,造yaml裡的結果儲存也設定了,資料庫路徑也設定了,但是出現了:一閃就退出的現象?報錯如下:

*** Error in `/home/hri/catkin_ws/src/LearnVIORB/Examples/ROS/ORB_VIO/VIO': free(): invalid pointer: 0x000000000c4880b0 ***

還有這個:

參考了下這個,可能說是記憶體不夠了!我重啟一下試試看看有沒有作用,因為我直接輸入roscore的時候也顯示:
