"tinygo test" fails #19

Closed dkegel-fastly closed 1 year ago

dkegel-fastly commented 2 years ago

Normally, one only needs the generated code to be tinygo-compatible, but it'd be convenient to be able to run tests with tinygo.

Currently, "tinygo test" fails with this error:

--- FAIL: TestGolden (0.01s)
    --- FAIL: TestGolden/mapconv (0.01s)
        couldn't exec 'go [list -e -json -compiled=false -test=true -export=false -deps=true -find=false -- .]': fork/exec /usr/bin/go: operation not implemented T

On Mac, one has to use -tags appengine to get past a problem in x/tools.

Sorry, but I don't have the bandwidth to deal with tinygo issues in this repo. Please send a PR if you know how to fix this. The error looks like an implementation restriction of tinygo to me.

Tinygo doesn't support exec (!), so whoever needs this working with tinygo is going to have to get creative (e.g. the tinygo version could add a Makefile that did the needed command before running the tinygo version of the test).

I don't understand why you need to build this tool with tinygo, or run its tests with tinygo.

gencodec is a code generator tool. It is expected that you run this tool on your development machine. You can just compile it with regular go. The output of the code generator can be compiled with tinygo, and doesn't need exec.
