Wrong libcurl version on arch-linux

Installing nodegit on archlinux failes while building with:

Error: /usr/lib/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by node_modules/nodegit/build/Release/nodegit.node)

I think this was introduced by PR #1195

The issue is, that nodegit wants libcurl abi-3, while archlinux default libcurl is abi-4.

How to fix

At least on arch-linux nodegit should link against libcurl-compat (which is abi-3 and provides libcurl.so.3 ~~as well as libcurl-compat.so~~), not libcurl (which is abi-4 and is incompatible with CURL_OPENSSL_3).

How to reproduce

Grab and boot a manjaro live-cd (https://manjaro.github.io/), which should be easier/faster then bootstrapping arch
Install nodejs with pacman/yaourt
Try to install nodegit with npm

Sidenote

Effected third-party tools are for example GitKraken on arch (see comments) which comes with prebuild nodegit binaries but fails to load because of missing/wrong symbols in libcurl.so.4. This can be fixed by loading libcurl-compat before libcurl using the LD_PRELOAD trick.

Is there any way to detect this situation for example using curl-config ? Is there something like curl-compat-config available?

I don't think there is an easy solution for this, here is the package content for libcurl-compat while default libcurl comes from this package.

Side note

I actually think there might be something entirely different wrong here.
When running npm install nodegit in a fresh directory it terminates rather quickly with:

[<build>]$ npm install nodegit

When I fetch nodegit manually from git, add the libgit2 repository to the vendor directory and run npm run rebuild from within, building succeeds, but interestingly it does take quiet a bit longer which I think has to be due to building libgit2.

Could it be that nodegit comes with a prebuild version of libgit2, which for some reason is build against libcurl ABI 3; aka is linked against libcurl.so which is symlink for ~~libcurl.so.3 and not libcurl.so.4 on that particiular system~~ libcurl.so.4 which contains backwards compatiblity code for ABI 3.

Another clues that the issue might be with a prebuild library can be seen when running ldd nodegit.node against the version that was ...

Both want to load libcurl.so.4 on my system, both were build by linking with -lcurl, but Exhibit A for some reason still has an undefined symbol.
There is also a difference in size, Exhibit A is rougly 6.3mb, while Exhibit B is rougly 7mb.

Conclusion

The issue seems to be with a prebuild library (probably libgit2) which was linked against libcurl -> libcurl.so.4 which also contained backwards compatible libcurl.so.3 code, while arch-linux libcurl.so.4 does not.

Proposed solution

Don't use prebuild libraries (on arch) IFF that is an option?

Yeah it's not that it's a prebuilt libgit2, its a prebuilt nodegit binary, which then fails to load. I think tin the case of arch, you'll need to run BUILD_ONLY=1 npm install nodegit, until we can figure out away around that.
