Linux Apps Tutorials - Herong's Tutorial Examples
∟GCC - C/C++ Compiler
This chapter provides introductions and tutorial examples about GCC C/C++ compilers. Topics include installing GCC C/C++ compilers; GCC compilation steps and settings; 'g++ -I' for include header files; g++ -l' for static/dynamic library files; 'g++ -shared' for building shared object (dynamic library) file; 'ldd' for checking dynamic library dependencies; 'make' tool for automation.
Install GCC C/C++ Compilers
"g++ --verbose" - GCC Compiler Steps and Settings
"g++ -I..." and CPATH Environment Variable
"g++ -l..." to Link with Library Files
"g++ -c" and "ar src" to Build Static Library
"g++ -shared" to Build Dynamic Library
"ldd" - Dynamic Library Dependency Checker
"make" - Manage Program Build Process
Takeaways:
- Installing the GCC C/C++ compilers can be done using "dnf install gcc"
and "dnf install gcc-c++" commands on CentOS systems.
- Dumping PHP environment information can be done by using the "php -i" command.
- Include header file paths can be specified by "g++ -I..." option or CPATH environment variable.
- Static and dynamic library files can be specified by "g++ -l... -l..." options.
- Static and dynamic library file paths can be specified by "g++ -L..." option
or LIBRARY_PATH environment variable at the link time.
- Dynamic library file paths can be specified by LD_LIBRARY_PATH environment
variable at the execution load time.
- Dynamic library dependencies of any executable program can be listed by the "ldd" command.
- Building (compiling, linking, ...) C/C++ programs can be automated by the "make" tool,
which uses "Makefile" to define tasks involved in the building process.
