The UNUSED_ALWAYS and UNUSED macros are defined in an artificial windows. A cross compiler is useful to compile code for multiple platforms from one development host. So far I have a working version GCC to cross compile my, so I have access to the native linkers and binary tools on Windows. org, or use MSys2 and pacman -S mingw64/mingw-w64-x86_64-clang. h header which I control that contains a number of utilities to help Xcode compile Windows stuff. It assumes you already know how to compile the code in question for the host architecture, and that you know how to choose additional include and library paths. It covers all supported toolchains, the three configuration files used to control building and debugging, IntelliSense setup, cross-compilation, NatVis visualizers, and pipe transport for remote debugging. Nov 23, 2025 · Clang: A cross-platform compiler (alternative to GCC) with excellent standards compliance. For general VS Code debugging concepts, see A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. cpptools). From grammar to binary. Cross-compilation using Clang ¶ Introduction ¶ This document will guide you in choosing the right Clang options for cross-compiling your code to a different architecture. A single install can output and compile code for every supported target, as long as a complete sysroot is available at build time. 3 days ago · I've implemented support for cross-compiling a Windows build on a Linux host using clang-cl. Direct compilation on the target platform might be About Langine is a language engine. langine.

MSVC (Microsoft Visual C++): Windows-only compiler, but useful if targeting Windows natively. dev programming-language pascal oberon cross-platform clang windows-10 win64 compiler-construction windows-11 cpp23 linux64 zig-build-system Readme The GNU Compiler Collection (GCC) (formerly GNU C Compiler) is a collection of compilers from the GNU Project that support various programming languages, hardware architectures, and operating systems. Basically, the issue boils down to a project assuming that Windows == MSVC toolchain and Clang != Windows, which can result in (typically) preprocessor logic errors. For example, a compiler that runs on a PC but generates code that runs on Android devices is a cross compiler.
