![]() ![]() Choose build and they will compile and be saved in XCode's derived data folder.Select the target to compile - either NairnMPM or NairnFEA.Once xerces is installed, open the NairnMPM.xcodeproj to compile the code by: This project is called NairnMPM, but it includes all MPM and FEA source code in two targets named NairnMPM and NairnFEA. Nairn-mpm-fea/Common/Projects/NairnMPM.xcodeproj The preferred method is to use XCode (but first you must install Xcode, install command line tools, and get a new compiler). Most development of NairnMPM and NairnFEA is done in MacOS X and thus compiling on MacOS X is easy. 4.4 Possible Changes Needed After Updating MacOS or XCode.But CDT(C/C++ Development Tooling) plugin of Eclipse can be used to compile C programs in Eclipse.įollowing is a screenshot of Eclipse IDE. Eclipse is mostly used for Java projects. Just like Xcode, Eclipse is also a popular IDE(Integrated Development Environment). LLVM can not be installed using an installer. It was developed to give more user-friendly messages in errors. An example of a toolchain is Gradle which is used in building applications. A toolchain is a programming tool that can be used to perform a task in software development. LLVM is a group of toolchains and compilers. For example, gcc test.c creates a.out as an executable.Īpart from Clang and GCC(GNU Compiler Collection), there are a couple more ways to compile C code.The code to compile would become gcc test.c -o test.Let us say code is written in the test.c file, and the output executable should test.gcc -o can be used to compile a C code.gcc -version can be used to check the version of GCC. Whereas Clang is a compiler toolchain that supports C, C++, and Objective-C natively.Ĭommand-line developer tools install gcc. GCC is a group of compilers that supports C, C++, Objective-C, Fortran, Ada, Go, and D.Whereas, Clang is developed to provide better performance than GCC. GCC is another compiler like Clang developed to compile different programming languages.GCC(GNU Compiler Collection) is a compiler for various programming languages like C, C++, and Objective-C developed by GNU.įollowing are some of the differences between GCC and Clang: ![]() Using GCC compiler in the Terminal window For example, clang test.c creates a.out as executable.If no output file name is used, a.out is used as an output file.The code to compile would become clang test.c -o test.Let us say the code is written in the test.c file, and the output executable should be test.clang -o can be used to compile a C code.Command-line tools install various compilers like Clang and GCC, which will be explained in the next sections.Once Xcode is installed, open a terminal window and enter Xcode-select -install, which installs command line developer tools.Xcode can be installed via App Store on Mac.Xcode is an IDE(Integrated Development Environment) developed by Apple.In the following sections, we will discuss different C compilers that can be used on MAC. IDE can be anything like Sublime text, Xcode, etc. Getting started on compilingįor compiling C code on Mac, we would need an IDE(Integrated Development Environment) which can be used to write code, and a compiler to compile the written code. The executable created for one platform can only be executed on that platform. Online C compilers compile C code and create an executable according to the platform. ![]() That is the reason for the size difference.Ĭ code can be written on any platform like Mac, Windows, etc. Whereas the size of the executable on Mac is 49 KB !!! Can you guess why there is a difference in size between C code and executable? The compiler takes care of loading stdio.h code and all the required code that is needed to run into an executable. Can you guess the size of the above C code and the executable it generates?Ĭ code only took 71 bytes to be stored. Mac C compilers convert a C code to an executable that can be run directly. ![]()
