Build Issue

[pgsnimble]

Hey!!

I am trying to use this library to encode the video and I can't find a way to make it work, everytime I try to build the app I am always getting the following error:

 => ERROR [builder-debug 2/2] RUN --mount=type=cache,target=/root/.cache/go-build     go build -gcflags="all=-N -l" -ldflags "-X main.BuildVersion=dev-debug" -o /tmp/gobuild/bin/jbl                            0.5s

Do you mind to help me?

This is a piece of my docker file

ARG UBUNTU_IMAGE_VERSION=24.04
ARG YT_DLP=2024.08.06

FROM golang:1.21.3 AS base

ENV CGO_ENABLED=0
ENV GOPRIVATE=github.com/ppaulogustavo

RUN go install github.com/jstemmer/go-junit-report@latest
RUN go install github.com/go-delve/delve/cmd/dlv@latest

WORKDIR /tmp/gobuild
COPY ./go.mod ./go.sum ./
RUN go mod download -x
COPY . .

FROM base as builder-debug
ARG BUILD_VERSION='dev-debug'

RUN apt-get update && apt-get install -y pkg-config libopus-dev libopusfile-dev moreutils

RUN --mount=type=cache,target=/root/.cache/go-build \
    go build -gcflags="all=-N -l" -ldflags "-X main.BuildVersion=${BUILD_VERSION}" -o /tmp/gobuild/bin/jbl

This is triggering the error when the build command is executed

Hi, weird, it looks like the stream.go file isn't available in that directory. Is the directory mounted from somewhere else, without that file? Try an ls and see if it exists before building.

I'm having the same issue on Windows. @pgsnimble were you able to solve it?

[SujithThirumalaisamy]

Yeah facing the same issue. but working if i build this in my mac without any args. If i build this specifically for linux. from my macbook this seems to throw this error. Every tried copying the files to the local and it still did't work

Hi @SujithThirumalaisamy, maybe you need to set CGO_ENABLED=1 because by default it is disabled for cross compiling. For example

CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build -ldflags="-w -s" -o app ./main.go

same error for me (CGO_ENABLED=0), hit this one after upgrading from 1.23 to 1.24. I will share more as I found out

I got this error when trying to use golang:1.25.3-alpine as the base image in my Dockerfile:

FROM golang:1.25.3-alpine AS builder

WORKDIR /build
ADD . /build

RUN apk --no-cache add make git pkgconf opus-dev opusfile-dev

RUN go build  ./cmd/app

Error:

I fixed it by adding the gcc and musl-dev packages. So the Dockerfile now looks like this:

FROM golang:1.25.3-alpine AS builder

WORKDIR /build
ADD . /build

RUN apk --no-cache add make git gcc musl-dev pkgconf opus-dev opusfile-dev

RUN go build ./cmd/app
