Can't find modules in std lib but GOROOT is set.

[Joematpal]

I set my GOROOT from the tinygo info.

I try to build. The build process looks for modules in the wrong cache directory.

I'm getting these errors. I think package sync/atomic is not in std package net/netip is not in std

I was using the latest version of tinygo and the same thing was happening so moved to 0.29

I'm sure I'm missing something in my setup. If anyone could help that would be great.

Why do new tinygo caches keep getting added to the cache dir? What is the rational around that? I just cleared everything and it just keeps growing. I feel like everytime I run tinygo flash it adds a new one.

[Joematpal]

I saw that the tinygo GOROOT in the info command had just changed. So I re ran it.

$ joematpal/nano_33_test » tinygo flash -target=arduino-nano33 -port=/dev/ttyACM0

I got a new error. I haven't seen this.

[Joematpal]

I removed all of the GOROOTs that i had all over the place. I see now the differences in the caches. Each target has its own goroot cache..

for instance tinygo info and tinygo info arudino-nan33 have to different caches.

What is the best way to identify which code is going to be in a cache?

the cache for tinygo info arudino-nano33 says it doesn't have certain modules.

What is the output from running tinygo env?

[sentientmachin3]

I'm having the same issue, but using a raspberry pico.

I set GOROOT and GOFLAGS from the result of tinygo info pico command, run tinygo build -o main.uf2 main.go and I get the error package sync/atomic is not in std, but with a different path from the one I specified.

Apparently tinygo keeps creating new folders, so it never compiles. I guess I'm going to try with an earlier version.

[sago35]

GOROOT and GOFLAGS are automatically set when running the tinygo command, so you don't need to configure them yourself. In general, it's better not to set them.

[sentientmachin3]

ok good to know!

[aykevl]

Indeed. Don't set GOROOT or GOFLAGS, they will only mess things up. And make sure they aren't set by checking env (run env | grep GOROOT or similar).

For IDEs, you can set GOROOT to the value in "cached GOROOT". For example, here is what the vscode-tinygo extension does:

https://github.com/tinygo-org/vscode-tinygo/blob/main/src/extension.ts#L51-L100

...but make sure these environment variables only apply inside the IDE! The IDE should (hopefully) have a way to configure these environment variables.

I got the similar error, go build works well, tinygo build report:

I got this, tinygo support only a sub set of go std api: https://tinygo.org/docs/reference/lang-support/stdlib/
