Do you know these commonly used gcc/g ++ command line parameters?
1. GCC-e source_file.c-E: Only pre-compiled. Directly output the pre-compilation result.
2. GCC-s source_file.c-S: only convert the source code to the assembly code and output the assembly code.

The cross-compilation toolchain is designed to compile, link, process, and debug program code for cross-platform architectures in which the operating system, applications, and so on embedded Linux systems are compiled and uploaded to the target board.First of all to clarify the difference between GCC and ARM-LINUX-GCC, GCC is the C language
compiler needs to make the appropriate options, filenames is the name of the relevant file, below I will introduce the next few options( Note: Be sure to distinguish between the case in the compilation options, they represent different meanings )(1)-C: Just compile without connecting to the executable file, the compiler is only generated by the input. C source code files. O is the suffix of the target file
When installing the gcc compiler in CentOS today is a network task assigned by the instructor, I found that I forgot to check the C language installation option when installing CentOS, leading to the failure to directly use the gcc-o command. Then, if you want to use YUM to connect to the network to install gcc in the
With my knowledge of the C language compilation process, I took a little time to draw a diagram, to provide you with a reference, I hope some of your problems can help.A few days ago just preliminary study of C language compilation process, feeling very deep. In the C language, the header file actually played a big role.1, header files can not need to compile2, you can view the specific statement3, the head file plus the implementation file of the O file submitted to the user, do not need to kno

The online explanation is: "You need to add-lstdc++, or using ' g++ ' rather than ' gcc ' as your driver program." That is, if you want to use the g++ compiler, then you need to add "- Istdc++ ".I tried it, and when I added "-istdc++" to the link, there was no problem.About g++, reminds me, in Ubuntu the next beginning installs the Code::Blocks, the prompt needs installs the g++. Originally Code::Blocks bui
