static link application with gocv

[HEUBITLYJ]

Description

i am trying to build an application with gocv with static link. However i get lots of errors.

Steps to Reproduce

1. write Dockerfile

FROM golang:1.17-buster AS builder

ARG OPENCV_VERSION="4.5.3"
ENV OPENCV_VERSION $OPENCV_VERSION

RUN apt-get update && apt-get install -y curl unzip

RUN curl -Lo opencv.zip https://github.com/opencv/opencv/archive/${OPENCV_VERSION}.zip && \
            unzip -q opencv.zip && \
            curl -Lo opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/${OPENCV_VERSION}.zip && \
            unzip -q opencv_contrib.zip && \
            rm opencv.zip opencv_contrib.zip

RUN apt-get -y update && apt-get -y install unzip wget build-essential cmake curl git libgtk2.0-dev  && \
    apt-get install -y pkg-config libavcodec-dev libavformat-dev libswscale-dev libtbb2 libtbb-dev  && \
    apt-get install -y libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev

RUN cd opencv-${OPENCV_VERSION} && \ 
	mkdir build && \ 
	cd build && \ 
	rm -rf * && \ 
	cmake \
    -D CMAKE_BUILD_TYPE=RELEASE \ 
    -D CMAKE_INSTALL_PREFIX=/usr/local \ 
    -D BUILD_SHARED_LIBS=OFF \
    -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-${OPENCV_VERSION}/modules  \
    -D OPENCV_GENERATE_PKGCONFIG=ON .. && \ 
	make -j $(nproc --all) && \
	make install  && \ 
	ldconfig

RUN go clean --cache 

RUN mkdir /go/test

COPY ./cmd/version /go/test

RUN cd /go/test && go mod init main && go mod tidy 

RUN cd /go/test && \
    go run main.go 

2. 构建镜像

sudo docker build -f ./Dockerfile -t docker_test:latest .

3. get lots of err

Your Environment

• Operating System and version: ubuntu18.04
• OpenCV version used: 4.5.3
• How did you install OpenCV? in docker
• GoCV version used: 0.29.0
• Go version: 1.17
• Did you run the env.sh or env.cmd script before trying to go run or go build?

i change last run of my dockerfile as：

RUN cd /go/test && \
    export CGO_CPPFLAGS="$(pkg-config --cflags opencv4)" && \
    export CGO_LDFLAGS="-g -O2 -L/usr/lib -L/usr/local/lib -L/usr/lib/x86_64-linux-gnu  $(pkg-config --libs --static opencv4) " && \
    GOOS=linux GOARCH=amd64 go build -v -ldflags "-extldflags "-static" -s -w" main.go

the err message become:

runtime/cgo
# runtime/cgo
/usr/bin/ld: cannot find -lIconv::Iconv
collect2: error: ld returned 1 exit status

[HEUBITLYJ]

i also try make static_install:

# builder image
FROM golang:1.17-buster AS builder

RUN apt-get update && apt-get install -y git sudo

RUN git clone https://github.com/hybridgroup/gocv.git 
RUN cd gocv && make deps
RUN cd gocv && make download
RUN cd gocv && make sudo_pre_install_clean
RUN cd gocv && make build_static
RUN cd gocv && make sudo_install
RUN cd gocv && make clean
RUN cd gocv && make verify

i got also get lots of err message: like undefined reference...
