Cross compile nim code for the HooToo HT-TM02 running OpenWrt. I'm using it like this:
Create a shell script (named ht02nim) with this content:
#!/bin/bash
docker run --rm -v ${PWD}:/src davidsblog/openwrt-build-ht-tm02-nim \
/bin/sh -c "cd /src; $*"
Then, you can use nim as normal, when prefixed with ht02nim, like this:
ht02nim nim -v
...which should print the version of the nim compiler, or to compile myprog.nim:
ht02nim nim c --cpu:mipsel --os:linux myprog.nim
Compilation is done inside the container, but the source code (and resulting binary) will be in the current directory of the host machine. I find it to be an easy way to cross-compile from many different machines.
