Hi Sebastian,
Thanks for that great effort. I'd aim to use this build system for my
RISC-V development.
I followed the user manual trying to build RISC-V targets and RTEMS
(aaf7f8b84) and here are a few comments:
* .waf bsp_defaults doesn't give an error when mistyping the BSP name,
but just outputs an empty .ini file.
If there is no matching BSP, then you get nothing. I think this is the
right thing to do. Doing a
./waf bsp_defaults --rtems-bsps=riscv/rv64imac_medany > bsps.ini
is not a recommended use case. You should only set the necessary minimum
of options.
Not sure, I only wanted to build a specific BSP variant without having
to build all variants. Is that not recommended?
This is fine, but I would not dump all options into the config.ini,
maybe just:
[riscv/rv64imac_medany]
COMPILER = clang
BUILD_TESTS = True
* ./waf complains about not finding gcc if I don't give it the
--prefix, even though it's in my PATH
Yes, this is currently the intentional behaviour. Should this be changed to
conf.find_program(XYZ, path_list=tools +
environ.get('PATH','').split(os.pathsep))
?
I think that makes sense (also for default prefix?), but it would
still be useful to be able to override that with --prefix to use
different installed toolchains if needed.
Chris, what is your opinion on this?
* dltests fail to build on RISC-V when BUILD_TESTS = True
Yes, this is work in progress. I should work now.
Thanks.
* Can't find any "*.exe" after a default build:
Ok, this is a bug, you should find the samples.
Is it reproducible?
I will have a look at this later.
* Can't notice a difference when I pass rtems-compiler=clang, it still
builds with gcc.
You have to set the compiler in the config.ini file, see latest user
documentation:
Thanks it works fine when I add the flag to config.ini. Is
rtems-compiler=clang useless this way?
This option is useful to get the default values depending on the
selected compiler, see example in:
