What was the last release of tinygo that worked in (if any)?

What was the last release of tinygo that worked in (if any)?

seems fine with tinygo version 0.17.0 windows/amd64 (using go version go1.16.13 and LLVM version 11.0.0)

tinygo 0.18..0 shows error: undefined symbol: errno

[dkegel-fastly]

fwiw, can be reproduced with

cd tests/tinygotest
tinygo test -c -target=nintendoswitch

[dkegel-fastly]

2565 includes a regression test for this, but doesn't run it yet from Makefile, as it is still failing.

[ultra-azu]

I could fix the errno issue in 0.18.0 by changing a line in runtime_nintendo_switch.go from go:extern to go:export. However, I think it's unrelated to the undefined syscall symbols in the current release.

[deadprogram]

Please see #4648 for a fix.

Tagging to close this issue on next release.
