交叉编译一个自动制作项目？

Question

I am developing an application for enocean . I am able to compile it for my Host system. I want to cross compile it for beaglebone black running openwrt . I have cross compiler and all other libraries. I am not sure how to change the existing configure, Makefiles to cross-compile it.

Please help!

Answer 1

you don't have to change anything. autotools comes with full cross-compilation support.

Just pass the proper --host= flag for your target architecture, eg:

./configure --host arm-linux-gnueabihf

This will look for toolchain programs with the given prefix (in the above case, it would look eg for a compiler arm-linux-gnueabihf-gcc ) in your current $PATH . Most cross-compiling toolchains should automatically adhere to this convention.
