What do you need to cross compile a program?
What you need. Basically, to cross-compile a program or library you need two things: a tool-chain running on your host, targeting your target architecture; the file system of your target machine (“sysroot” in the following).
Is the C library part of the cross toolchain?
The C library is part of your cross toolchain. That’s why the headers are found and the program correctly links and runs. This is also true for some other very basic system libraries like libm and libstdc++ (not in every case, depends on the toolchain configuration).
How to work with external libraries when cross compilation?
Regarding cross compilation you will surely find loads of information on the internet and maybe ncurses has got some pointers in its shipped documentation, too. When compiling and building cross-tool chain during configuration they will provide sysroot.
Can you cross compile Linux on a 96board?
Cross compilation will happen on a Linux x86 machine for 96Boards ARM device. The image on your board/host computer might be out of date. This is possible even when using the stock images, recent downloads, or a newly flashed versions of any operating system. A few useful commands will help us make sure everything on the board is current:
What’s the difference between host and target in cross compile?
‘target’ is the machine (or architecture, or platform) that is intended to run the code. In the ‘usual’ building process, the ‘host’ and ‘target’ platform are the same. For example, you use your PC to compile a code to make it run on the same PC. In cross-compilation, the ‘host’ and ‘target’ platform differs.
What does it mean to cross compile on Raspberry Pi?
Cross-compilation Cross-compilation is the process that allow you to compile code that is supposed to run on a ‘target’ architecture, and to do that while working on a different (‘host’) architecture. For example, you may want to compile a program for your Raspberry-Pi (the target architecture) on your laptop (the host architecture).
