Hello,
I am trying to cross compile Boost libraries for RTEMS (Real-Time Executive for Multiprocessor Systems) on RISC-V.
I have the toolchain available (e.g., riscv-rtems5-gcc).
Based on the Boost.Build user manual, I am not sure this is actually possible.
Following the ‘cross-compile’ instructions in section 4.9, it appears I have to supply a specific target operating system and that RTEMS is not supported.
Am I reading this correctly?
Yes, you need to specify a target OS if you want to do it cleanly. But...
Is there any other way for me to cross-compile Boost for use with RTEMS?
You can also just ignore the OS and make your toolset only usable in that OS. It defaults to "unix" at the OS. I.e. you can use "unix" as the OS in your use case. Or...
You can also adhok add a new OS to the OS features with:
==
import feature ;
feature.extend os : rtems ;
feature.extend target-os : rtems ;
feature.extend host-os : rtems ;
==
With that in your user-config.jam, you can then `b2 target-os=rtems`.
