CMAKE_ASM_COMPILER is supposed to point to a compiler wrapper (i.e. gcc), _not_ to as directly. If it is not set, it will use the value of CMAKE_C_COMPILER. That's exactly what we want, so there is no need to set CMAKE_ASM_COMPILER at all. For target, we don't set CMAKE_ASM_COMPILER either. Setting CMAKE_ASM_COMPILER leads to build failures for any package that actually tries to build .S files for the host - like llvm. This is why llvm has an override for it.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
