A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. For example, a compiler that runs on a PC but generates code that runs on Android devices is a cross compiler. A cross compiler is useful to compile code for multiple platforms from one development host.
Boot messages of a Linux kernel 2.6.25.17. The basic components of the Linux family of operating systems, which are based on the Linux kernel, the GNU C Library, BusyBox or forks thereof like μClinux and uClibc, have been programmed with a certain level of abstraction in mind.
That is to say, it is a "boot loader" that reads Linux kernel source code from disk, writes executable instructions to memory, and begins running it. This did require changes to the Linux build process. TCC has been used to compile GCC, though various patches were required to make this work. [8]
The GNU C Library, commonly known as glibc, is the GNU Project implementation of the C standard library.It provides a wrapper around the system calls of the Linux kernel and other kernels for application use.
Some assemblers are components of a compiler system for a high-level programming language and may have limited or no usable functionality outside of the compiler system. Some assemblers are hosted on the target processor and operating system, while other assemblers (cross-assemblers) may run under an unrelated operating system or processor.
The Linux from Scratch project, like BitBake, also supports cross-compiling Linux for ARM embedded systems such as the Raspberry Pi and BeagleBone. [ 7 ] [ 8 ] The book Hardened Linux From Scratch (HLFS) focuses on security enhancements such as hardened kernel patches, mandatory access control policies, stack-smashing protection , and address ...
Linaro Limited is an engineering organization that works on free and open-source software such as the Linux kernel, the GNU Compiler Collection (GCC), QEMU, power management, graphics and multimedia interfaces for the ARM family of instruction sets and implementations thereof as well as for the Heterogeneous System Architecture (HSA).
To make cross-compiling possible for Scheme code, Chicken imposes a model of separate compiling: A compiled module consists of two shared libraries. One library contains the actual code which will be used at runtime (compiled for the target platform), and the other is an import module , which will be used to load the code which runs at compile ...
