This article mainly introduces how linux compiles cpp files, which can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

If we have a written demo.cpp function, how can we compile the program and run the result in linux system?

We can carry out the order:

Gmail + demo.cpp-o demo

Generate the executable program demo, and then execute the command:

. / demo

Then you can execute the program.

Similarly, if it is a .c file, you can execute the command:

Gcc demo.c-o demo

In addition, when compiling, if we need to add the header file and the path of the library file, we can refer to the following parameters:

-l: used to specify the library to be linked by the program, and the-l parameter is followed by the library name. The relationship between the library name and the real library file name can be interpreted as: if the library name is caffe, its library file name is libcaffe.so.

-L: the compiler follows the path specified by-L to look for library files. Generally, you can specify multiple library files with-l at a time after-L. For example, .a (static library) and .so (dynamic library) under linux.

-I: the compiler follows the path specified by-I to search for the header file. (xxx.h)

For example, suppose I have written a demo.cpp file and need to use the related files of caffe. You can execute the command:

Gmail + demo.cpp-o demo-I ~ / caffe/include/-D CPU_ONLY\-I ~ / caffe/.build_debug/src/-L ~ / caffe/build/lib-lcaffe thank you for reading this article carefully. I hope it is helpful for everyone to share how linux compiles the contents of cpp files. At the same time, I also hope you can support us, pay attention to the industry information channel, find problems and learn detailed solutions!
