LibGit2Sharp.Core.NativeMethods cannot be initialized: Unable to load shared library 'git2-7ce88e6' or one of its dependencies

Trying to use GitVersion dotnet tool with .net core 3 sdk docker image that runs on GitLab Shared Runner (which is CoreOS).

The 5.0.2-beta.1+95 (contains #1849) throws this exception:

as I mentioned #1824 (comment) the debian 10 is not yet supported. I'll need to think of a way to make it supported

[nZeus]

what do you think about the idea of having another version of GitVersion tool with that dependency included or ilmerged?

GitLab CI runners are based on CoreOS and I cannot find a way to install packages there :(

[arturcic]

Are you able to run Docker images there? is so I'd recommend to use the image https://hub.docker.com/layers/gittools/gitversion/5.0.2-beta1-95-linux-debian-9-netcoreapp3.0/images/sha256-ba496f1885415be1bcac0256f0b1af4b6d1ab48db2d1de6116ce6e15462cf419

This image throws a different error:

Since others will come here looking for the same thing for alpine-3.9 it should be mentioned that alpine 3.9 was only supported in the most recent published packages. 5.0.2.beta+

[jburger]

Also spotted on Ubuntu 19.04+libcurl4

[ajaskiewiczpl]

When will GitVersion be supported on Debian 10?

[mprokopov]

It seems guys have figured out a root cause libgit2/libgit2sharp#1741

See this discussion libgit2/libgit2sharp#1732

I guess now it is required a new release to be built.

[deadman2000]

Temporary solution for Docker:

export LD_LIBRARY_PATH=/root/.nuget/packages/gitversion.tool/5.1.2/tools/netcoreapp3.0/any/runtimes/debian.9-x64/native/

[arturcic]

@deadman2000 thanks for sharing

[robertcoltheart]

Can we get a fix for this? We are struggling with this issue as well under amazon linux.

[asbjornu]

@robertcoltheart, doesn't @deadman2000's LD_LIBRARY_PATH solution work for you?

[robertcoltheart]

@asbjornu No, the above export command doesn't seem to help, we are still getting the same error

[deadman2000]

@robertcoltheart If you use GitVersion as tool, this Dockerfile should helps:

ARG DOTNET_SDK=3.0
FROM mcr.microsoft.com/dotnet/core/sdk:$DOTNET_SDK

ENV PATH="${PATH}:/root/.dotnet/tools"

ENV GITVERSION_VERSION=5.1.2
RUN dotnet tool install -g GitVersion.Tool --version $GITVERSION_VERSION
ENV LD_LIBRARY_PATH=/root/.dotnet/tools/.store/gitversion.tool/${GITVERSION_VERSION}/gitversion.tool/${GITVERSION_VERSION}/tools/netcoreapp3.0/any/runtimes/debian.9-x64/native/
