Error building cgo: cannot parse $WORK/b046/_cgo_.o as ELF, Mach-O, PE or XCOFF about napi-go

Slight progress. Here's what I did...

1. Fork this repo
2. Comment out the flags (that didn't work)
3. Put the flags back in

I then got a different error even though I hadn't changed anything.

New error:

# [github.com/Automattic/napi-go](http://github.com/Automattic/napi-go)

../../../go/pkg/mod/github.com/!automattic/[email protected]/instance_data.go:5:10: fatal error: 'node/node_api.h' file not found
#include <node/node_api.h>
^~~~~~~~~~~~~~~~~
1 error generated.

Figured that out - it was because napi-go expects node to be at /usr/local/include/node and mine is under .nvm.

So I did this:

sudo ln -s /Users/<username>/.nvm/versions/node/v21.7.3/include/node /usr/local/include/node

(I also added node-gyp with these commands, and my simple binding.gyp file that does nothing is in the above linked repo)

• yarn add -D node-gyp
• then add a binding.gyp file
• node-gyp configure (requires the binding.gyp file)
• node-gyp build

SO NOW

I run this:

go build -buildmode=c-shared -o "example.node" .

and we have this error:

cgo: cannot parse $WORK/b046/_cgo_.o as ELF, Mach-O, PE or XCOFF

and I think I might post on stack overflow? I see some other issues of this online but I haven't been able to figure out the solution

@annie-elequin are you on mac arm ?

We had a similar issue and we fixed it by editing the various node_api_...flags to adjust the -arch x86_64

Note: We also used go1.18 to make it work though, not sure if it works on 1.19+

@ACenterA
yes that did it!
here are the changes to our flags that we made that worked:
