dotnet/source-build: Unable to load shared library 'git2-8e0b172'

I am working on a Dotnet package for Exherbo Linux.

Following the error message below, I realized that there were several libraries libgit2-8e0b172.so

s0dy ~/source-build (release/3.0) find . -name libgit2-8e0b172.so

./packages/libgit2sharp.nativebinaries/1.0.235/runtimes/debian.9-x64/native/libgit2-8e0b172.so
./packages/libgit2sharp.nativebinaries/1.0.235/runtimes/fedora-x64/native/libgit2-8e0b172.so
./packages/libgit2sharp.nativebinaries/1.0.235/runtimes/alpine-x64/native/libgit2-8e0b172.so
./packages/libgit2sharp.nativebinaries/1.0.235/runtimes/linux-x64/native/libgit2-8e0b172.so
./packages/libgit2sharp.nativebinaries/1.0.235/runtimes/rhel-x64/native/libgit2-8e0b172.so

I also noticed that the lib for debian and fedora was related to openssl-1.1

s0dy ~/source-build (release/3.0) lddtree packages/libgit2sharp.nativebinaries/1.0.235/runtimes/debian.9-x64/native/libgit2-8e0b172.so

libgit2-8e0b172.so => packages/libgit2sharp.nativebinaries/1.0.235/runtimes/debian.9-x64/native/libgit2-8e0b172.so (interpreter => none)
    librt.so.1 => /usr/host/lib/librt.so.1
    libpthread.so.0 => /usr/host/lib/libpthread.so.0
        ld-linux-x86-64.so.2 => /usr/host/lib/ld-linux-x86-64.so.2

    libz.so.1 => /usr/host/lib/libz.so.1
    libc.so.6 => /usr/host/lib/libc.so.6

While the others (alpine, linux and rhel) are related to openssl-1.0

    libcrypto.so.1.0.0 => not found
    libz.so.1 => /usr/host/lib/libz.so.1
    libc.musl-x86_64.so.1 => not found

• The version of my distribution is not recognized, I guess I use the linux-x64 version that is related to openssl-1.0. So I have libssl and libcrypto that are not found as you can see above.

• I tried replacing my /etc/os-release file with that of a debian machine and it works.

• I would like to find a solution, make a patch. Which file exactly checks the distribution? How to tell him to use the good library related to openssl-1.1?

Reproduction steps

1. git clone https://github.com/dotnet/source-build.git
2. cd source-build.git
3. ./build.sh

Expected behavior

successful compilation ?

Actual behavior

Exherbo Linux trying to compile dotnet/source-build release/3.0

Bắt đầu với LibGit2Sharp/Core/NativeMethods.cs, đặc biệt là đường dẫn LoadNativeLibrary() được nêu trong stack trace, và kiểm tra các native asset trong packages/libgit2sharp.nativebinaries/1.0.235/runtimes/. Tái hiện bằng ./build.sh trên Exherbo Linux và so sánh việc phát hiện bản phân phối dựa trên /etc/os-release. Được coi là hoàn tất khi thư viện native libgit2 tương thích với OpenSSL phù hợp được tải trong quá trình clone của source-build.
