Ubuntu system --- C ++ Eclipse start of the project
After installing Eclipse, just like any other project that, like, first test will work.
First, a test hello world example
two, OpenCV test using a picture display example of a normal new construction, reference may be made as follows: (1) Photo c ++ eclipse c ++ program using a second @https: //wenku.baidu.com /view/91bfcde5daef5ef7ba0d3cc7.html (2) Ubuntu16.04 configure Eclipse development OpenCV, icon "open Eclipse, create a C ++ project, named lena" @https: //www.cnblogs.com/eczhou/p/7860598.html (3) ubuntu the eclipse opencv configuration works, also illustrating the step @https: //blog.csdn.net/CAIYUNFREEDOM/article/details/89637607 (. 4) arranged speed Ubuntu + Eclipse CDT + Opencv2.3.1 environment @https: / /www.cnblogs.com/shihty/archive/2012/10/24/2737552.html create OpenCV project illustrates @https use (5) Ubuntu under the Eclipse CDT: //blog.csdn.net/wuguangbin1230/article/details/75576069 way will encounter a lot of problems, a little bit of resolve: (1) to solve the Semantic error the Eclipse @https: //blog.51cto.com/3387980/1717086 (2)

"If the library is successfully installed, however, the eclipse method library includes the following:
for example: to include log4cxx
my installation path is / usr / local / lib / libs
then find a lib folder to determine which has a liblog4cxx.so file (this is an important sign !!!) in the directory.
so long as the installation path added lib, i.e., / usr / local / lib / libs / lib desired path comprising

I found an error in the file, find the location, added to the environment, OK.
(3) the Eclipse run C ++ issues Launch failed, Binary not found
create HelloWorld project, solution, toolbars run-> run configuration; double-click the c / c ++ application appears HelloWorldCPP debug, select; under the Main tab, c / c ++ application: search project -> check HelloWorldCPP-> OK; under common tab, check the Debug and Run-> apply-> run; follow-up can click on the toolbar triangles run. @https: //blog.csdn.net/u011939755/article/details/80781651
Configuring MinGW- resolve on Eclipse C ++ appears Launch failed, solutions Binary not found the problem (yet attempt is successful, and this really does not know about it!)

(4) OpenCV configuration, the configuration is good, run the test program with no error, the picture does not show? ?

Summary: you must want to use OpenCV with a good Eclipse + OpenCV environment, or every step in error. Of course, this is the first time using Eclipse + OpenCV, after the experience there.

再指明lib : lib是要自己找的，依旧快捷键Ctrl + alt + T 召唤出终端，这次输入： pkg-config --libs opencv 会打印出所有的libs，应该是下面这些： opencv_shape;opencv_objdetect;opencv_ml;opencv_stitching;opencv_videostab;opencv_photo;opencv_dnn;opencv_calib3d;opencv_superres;opencv_video;
opencv_features2d; opencv_highgui;opencv_videoio;opencv_imgcodecs;opencv_imgproc;opencv_flann;opencv_core 可以全部导入，以免找不到。 找到 GCC C++ Linker，在右侧 First in Library search path (-L) 中加入这些库，通过加分号了，所以可以直接导入，eclipse 会自动换行分开，不然就要一个一个手动输入。
还有其他问题，系统路径是不是没有配好，为什么每次新建工程，上述配置都没有了？！ 在继续解决。
