`uname` on Apache #NuttX RTOS became unusually quieter: Commit Hash is Missing! Watch as we stomp the seemingly simple bug ... That turns out to be something seriously sinister! (Spoiler: Static Vars are broken)
Let's compile Apache #NuttX RTOS ... For all Arm32 Targets

@Popolon Yeah I would love to use an Arm Server. Too bad I'm stuck on Ubuntu x64...
(1) To compile NuttX for all targets (Arm, RISC-V, Xtensa etc), we need the Docker Image for NuttX. Which runs on x64 only, not Arm64:

(2) Today I'm running the NuttX Build Farm on a Refurbished 12-core Ubuntu Xeon Server, 64 GB RAM. Super affordable, compared to Arm servers:

I wonder if it wouldn't be more efficient to use an ARM host ? so ARM no cross compile and RISC−V is really near architecture, probably less cross emulation effort? Will try to deploy some on a 32GB RK3588 mini-ITX board I've, but need to install other thing that Arch, Arch Linux ARM is the only linux ARM distribution that doesn't have a the RISC-V crosscompiler sadly.
Here's how we build one single Target Group for Apache #NuttX RTOS ... With the #Docker Image for NuttX
