Eclipse CDT standard library header file settings

When using eclipse CDT to develop C/C ++ projects, the GCC/g ++ header files and symbols on the fedora machine can be automatically disfound from the special version of Linux on the eclipse official website, however, I cannot use slackware. You need to manually add the standard library header file path/usr/include,/usr/local/include ......, However, this is also troublesome. You can check it today by setting c_include_path/cplus_include_path.

$ Echo "int main () {return 0;}"> a1.c

$ Gcc-V a1.c

......

/Usr/include
The search list ends.

In eclipse, choose Window --> preferences --> C/C ++ --> build --> environment to add environment variables.

C_include_path =/usr/local/include:/usr/lib64/GCC/x86_64-slackware-linux/4.5.2/include:/usr/lib64/GCC/x86_64-slackware-linux/4.5.2/include-fixed: /usr/include

Cplus_include_path =/usr/lib64/QT/include:/usr/lib64/GCC/x86_64-slackware-linux/4.5.2/http://www.cnblogs.com/http://www.cnblogs.com/include/c++/4.5.2:/usr/lib64/gcc/x86_64-slackware-linux/4.5.2/http://www.cnblogs.com/http://www.cnblogs.com/include/c++/4.5.2/x86_64-slackware-linux:/usr/lib64/gcc/x86_64-slackware-linux/4.5.2/http://www.cnblogs.com/http://www.cnblogs.com/include/c++/4.5.2/backward:/usr/local/include:/usr/lib64/gcc/x86_64-slackware-linux/4.5.2/include:/usr/lib64/gcc/x86_64-slackware-linux/4.5.2/include-fixed:/usr/include

Remember to select the following append variables to native environment.

After the project is added, the header file of the standard library is normal.
