build2-base build system prototype for CHERI microcontroller development
This is a prototype of a build2-base build system for the CHERI
microcontroller development as described in this thread.
This prototype uses the standard GCC/Clang toolchain and maps the concepts in the above description as follows:
- library -- static library (
.a) - compartment -- shared library (
.so) - firmware -- executable
- loader and scheduler -- generated source files
- firmware linker script -- generated source file with
main()
The files of interest are cherimcu/buildfile which is what the
user would write and build/cherimcu.build which contains
all the CHERI-specific target types, rules, etc., and which is what CHERI
developers would supply to the user.
To try it yourself, get build2, clone this project, and then run
b from the project root:
$ git clone https://build2.org/cherimcu.git
$ cd cherimcu
$ b
Or, for the out of source build:
$ cd ..
$ b cherimcu/@cherimcu-out/
Or to configure an out of source build (and also specify the C/C++ toolchain):
$ b configure: cherimcu/@cherimcu-clang/ config.cxx=clang++
$ b cherimcu-clang/
$ cd cherimcu-clang/
$ b
