Go run important works, go construct -o important.go fails with GOOS and GOARCH specified – Getting Assist

Hello all.

once I do a go run important.go it runs – on my MBP -M1
once I do a go construct . it builds,
once I run attempt to construct it with the beneath exports or execute the Makefile it fails – error beneath

<ps I’ve tried this identical command/steps on a amizonlinux based mostly EC2 occasion (x86-64) on AWS, as I intend to deploy to Lambda>

BINARY_NAME=important
export GOOS=linux
export GOARCH=amd64
export CGO_ENABLED=0

.DEFAULT_GOAL := deploy

deploy:
	
	go construct -o ${BINARY_NAME} .
	zip -r operate.zip important
	aws lambda update-function-code --function-name "S3JSONDecomposer-Golang" --zip-file fileb://operate.zip --region="af-south-1" | jq .    

run:
	go run ${BINARY_NAME}.go

./important.go:130:14: undefined: kafka.ConfigMap
./important.go:142:25: undefined: kafka.NewProducer

please assist

Hello @georgelza,

I assume you utilize confluent-kaftka-go. This library relies on the C library librdkafka, due to this fact you want CGO for compiling.

Cross-compiling is easy for pure Go code solely. I’d maybe use a VM on the Mac (Docker Desktop, Podman Desktop, OrbStack, Colima,…) to arrange a Linux construct surroundings.

i’ve tried (with Python) docker compiling and sadly all the time battle, for Python I ended constructing this EC2 pictures, that has the goal OS/Structure…
As talked about, tried this compile on the EC2 occasion additionally and ended with the identical error, will attempt once more rapidly, by no means know

will advise, thanks for the perception.

setting CGO_ENABLED=1 (within the MAC, lets go attempt on my EC2 occasion)

go construct -o important .

make: *** [deploy] Error 1

with my code copied onto the EC2 occasion, based mostly on Amazon Linux… x86-64… I’m again at

that is with CGO=0 … as I’d assume it’s the identical structure as my goal, and it’s x86-64 so i’m guessing it’s the identical structure because the supply.
if I set CGO=1 then it complains for lack of C compiler. should see what c compiler to put in, by no means performed that earlier than.

make deploy
go construct -o important .
# jsondecom
./important.go:130:14: undefined: kafka.ConfigMap
./important.go:142:25: undefined: kafka.NewProducer
make: *** [Makefile:11: deploy] Error 1

AWESOME, as mentioned, thanks for pointers.
put in gcc
set CGO=1
reran Makefile, it compiled…
thanks, now to check the app rapidly.

eish…
it appears the required glib libs that i put in on my EC2 picture to get it compiled isn’t on the lambda OS by default, unusual by means of, lack of know-how, however i believed this is able to be an entire/self contained binary…

The CGO setting have to be set every time Go consists of C. That is impartial of the goal structure.

Solely wir pure Go. Any included C code has C dependencies.

I don’t know something about LambdaOS, however I discovered this Stackoverflow thread that signifies that you just may must set LD_LIBRARY_PATH and doubtless additionally provide the required glibc someway.

with lambda you solely present your code, you don’t have entry to any exterior Os stage variables.

Lambda’s are based mostly/deployed onto amazonelinux OS’s builds.
thanks for the stackoverflow pointer, will go look.
