cannot create context: incompatible header (1.20.0) and library (1.18.0) versions about go-fitz HOT 8 CLOSED

I just tried a basic example with the same Dockerfile and there are no issues.
So, I copied the example from README, test.pdf, I did go mod init example, then docker build --no-cache -t example and docker run -it example:latest, I also added some time.Sleep, so I can check with docker exec that files are created in /tmp/fitz*.

You don't need to install all those libraries if you are not building with extlib, just -tags musl is enough. So either don't install libraries or build with extlib, but in that case, you need 1.20.0 installed as there have been some changes.
See here for a minimal docker #35 (comment)

@gen2brain thanks for the quick response,

Tried this

FROM golang:alpine
WORKDIR /app
RUN apk add --no-cache git gcc musl-dev
COPY go.mod go.sum ./
COPY example.go test.pdf ./
RUN go mod download
RUN go build -tags musl -o /example
CMD [ "/example" ]

build was successful

But still getting this error ⬇️

Do you have any idea about cause of the issue?

This comes when it tries to read the PDF

from go-fitz.

Well, besides checking your go.mod file, or building a docker image without using the cache, no idea. Can you try the exact steps I did, does it work then?

from go-fitz.

I followed the exact steps. But it didn't worked ☹️, image is running but at the time of reading the pdf, getting the context error mentioned above
This is my go.mod

module pdf-transcoder
