Eclipse add c/C + + header file Jump __c++

Eclipse in the new C or C + + to the project, the header file alarm, display "unresolved inclusion:<stdio.h>" although not affect the project to compile and run, it is also unable to check the document, people feel really uncomfortable. The following is a foreign to the Web site to see the solution, I organized a bit to share. about configuring the/C + + development environment under eclipse here's not much to say.

View the C library file to the path under the terminal:$ echo "int main () {return 0;}" > a1.c $ gcc-v a1.c #include "..." search starts here: #include <...> se Arch starts here:/usr/lib/gcc/x86_64-linux-gnu/4.9/include/usr/local/include/usr/lib/gcc/x86_64-linux-gnu/4.9/in 　　Clude-fixed/usr/include/x86_64-linux-gnu/usr/include the end of the search list. ......
to view the C + + library files to the search path:$ echo "int main () {return 0;}" > A1.cpp $ g++-v a1.cpp #include "..." search starts here: #include <...&gt ; Search starts here:/usr/include/c++/4.9/usr/include/x86_64-linux-gnu/c++/4.9/usr/include/c++/4.9/backward/usr/ lib/gcc/x86_64-linux-gnu/4.9/include/usr/local/include/usr/lib/gcc/x86_64-linux-gnu/4.9/include-fixed/usr/ Include/x86_64-linux-gnu/usr/include
End of search list. The above path varies from person to person.
In Eclipse, menu window--> Preferences--> C + +--> build--> Environment Add environment variable C_include_path 6_64-linux-gnu/4.9/include:/usr/local/include:/usr/lib/gcc/x86_64-linux-gnu/4.9/include-fixed:/usr/include/x86 _64-linux-gnu:/usr/include Cplus_include_path =/usr/include/c++/4.9:/usr/include/x86_64-linux-gnu/c++/4.9:/usr/ include/c++/4.9/backward:/usr/lib/gcc/x86_64-linux-gnu/4.9/include:/usr/local/include:/usr/lib/gcc/x86_64- Linux-gnu/4.9/include-fixed:/usr/include/x86_64-linux-gnu:/usr/include Remember to select the following append variables to native 　　Environment. Restart Eclipse's new project when you are finished adding it.
