Building with -extldflags=-static

[Janso123]

Hi, Is there an option to build it with a static flag?

That's my Dockerfile and it core-dumps on me or throws linker error `FROM golang:alpine as builder

RUN apk add musl-dev vips-dev gcc

WORKDIR /src COPY . .

RUN go build -o /bin/app --ldflags '-linkmode external -extldflags=-static' . `

@Janso123 did you manage to solve it? I have the same issue

@AttilaTheFun @tonimelisma have you guys been able to build a static go binary with libvips?

Hey @sonu27 I've never tried it personally.

Same issue.

Without options --ldflags '-linkmode external -extldflags "-static" -s -w' the same errors. It seems I'm doing something wrong...

[omar391]

Did you try with musl libc?

try this one: https://github.com/davidbyttow/govips/issues/376#issue-1832134159

[moguchev]

Yes. It's seems that static build is impossible (Or some magic should happen). Without static flag everything is fine.

Here is my final Docker file (build is working on MacOS Sonoma 14.1.1 with M1 and also on Ubuntu):

same issue on windows native building, it worked on libvips-8.10, but can not worked on 8.14. Anyone has idea?
