Build fails while installig Rust

albertskog opened this issue · 1 comments

Hi! Trying to run this example on a OrangePi Zero (armv7) but can't get past the stage where it installs Rust;

# Install Rust
RUN curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --default-toolchain 1.37.0 -y

Here is the full log output of a fresh build. Interesting part is right at the end, looks like memory allocation fails while installing rustc:

I also tried changing the Rust version from 1.37.0 to 1.42.0 with more or less the same results.
Any ideas what might be wrong? I'm using a 32 GB SD so not sure why memory allocation would fail?

I have been digging around some more and it seems the issue is that the Orange Pi Zero's 512 MB RAM is simply not enough to install rustc, even when limiting RAM usage to the minimum with export RUSTUP_UNPACK_RAM=200000000. 😢

I'll have another try at getting cross compilation working instead..
