libgit2 alpine linux docker错误

Question

Ok, This is above my understanding. I have really no idea what exactly is wrong here but something is. I am on the verge of breaking by banging my head on the wall and yet nothing came up. Can any kind soul please help me.

This is my Dockerfile -

FROM golang:1.7-alpine
RUN echo http://dl-4.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libgit2

RUN pkg-config --print-errors --exists libgit2

I have wrote it with advice from here - How do I install libgit2 on Alipne linux

And this is the end result -

Step 4 : RUN pkg-config --print-errors --exists libgit2
 ---> Running in f69f97142e81
Package libgit2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgit2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libgit2', required by 'world', not found
The command '/bin/sh -c pkg-config --print-errors --exists libgit2' returned a non-zero code: 1

So what is it that is wrong? Why it can not see the installed libgit2 (0.24.1-r0). I really tried every possible way to get this one package built and installed in my docker container and I can not simply do it. I have no idea what is wrong. Please help me.

-------------- EDIT

The last command in my Dockerfile is actually taken from here http://lists.subsurface-divelog.org/pipermail/subsurface/2014-November/015646.html

And certainly the issue depicted there and the one that I have is not the same

---------------- EDIT 2

Anyone interested in doing the effort all by your self can follow this -

FROM golang:1.7-alpine
ENV TARGET venv
RUN echo http://dl-4.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libcurl
RUN apk update && apk add cmake
RUN git clone git://github.com/libgit2/libgit2.git
WORKDIR $GOPATH/libgit2
RUN git checkout v0.24.0 && rm -rf build && mkdir build && cd build \
    && cmake .. -DCMAKE_INSTALL_PREFIX=$TARGET -DBUILD_CLAR=OFF && cmake --build . --target install
ENV PKG_CONFIG_PATH /go/libgit2/build/venv/lib/pkgconfig:$PKG_CONFIG_PATH

For a simpler and cleaner approach follow the accepted answer. This one only has the advantage of having libgit2 version which is not available via apk yet.

One more thing - -DBUILD_CLAR=OFF is there because I did not want to install Python in the image just to run the tests

Answer 1

You are trying to compile a package using libgit2 , so you need the libgit2-dev development package with the headers, pc file, etc.

This docker file file builds git2go successfully:

FROM golang:1.7-alpine
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libgit2-dev
RUN go get -v github.com/libgit2/git2go
