If a module sets MODULE_STATIC_LIB to true, that module will generate a .a file instead of a partially linked .o file. When WITH_LINKER_GC is enables, unreferenced code and data in c files are dropped from the final elf file. This does not work for most assembly files, since they put code and data directly into the .text and .data section. If a .a file is used instead however, files that have no external references are dropped regardless of which sections they have. If MODULE_STATIC_LIB is true, this change also disabled LK_INIT_HOOK* as files using this as the only entrypoint would also be dropped. Change-Id: I846ac1bf63018d1d713ca841e03191b1fac35bf4
LK
The LK embedded kernel. An SMP-aware kernel designed for small systems.
See https://github.com/littlekernel/lk for the latest version.
See https://github.com/littlekernel/lk/wiki for documentation.
Builds
To build and test for ARM on linux
- install or build qemu. v2.4 and above is recommended.
- install gcc for embedded arm (see note 1)
- run scripts/do-qemuarm (from the lk directory)
- you should see 'welcome to lk/MP'
This will get you a interactive prompt into LK which is running in qemu arm machine 'virt' emulation. type 'help' for commands.
note 1: for ubuntu: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from http://newos.org/toolchains/arm-eabi-5.3.0-Linux-x86_64.tar.xz
