"undefined symbol: gcry_control" after building in linux/amd64 alpine #1975
Description
System information
- node version: 18.15.0
- npm or yarn version: yarn 1.22.19
- OS/version/architecture: Linux a2a48d191f5f 5.15.49-linuxkit Comment all code methods #1 SMP PREEMPT Tue Sep 13 07:51:32 UTC 2022 x86_64 GNU/Linux
- Applicable nodegit version: 0.27.0
The issue
I built with following command:
apt-get install -y libgit2-27 libgit2-dev libkrb5-dev build-essential python2
alias python=python2
yarn --frozen-lockfileit builds fine, but when I try to run my project, as soon as it requires nodegit:
node: symbol lookup error: /usr/share/apps/node_modules/nodegit/build/Release/nodegit.node: undefined symbol: gcry_control
On my runtime I have following packages installed:
apt-get install -y git libgit2-27 libkrb5-dev libssl1.1 libgcrypt20
When I inspect the built file with ldd node_modules/nodegit/build/Release/nodegit.node it says this:

The workaround
I fixed it by running my process with LD_PRELOAD="/lib/x86_64-linux-gnu/libgcrypt.so.20" node build/server.js
The root-cause and additional questions
- Shouldn't the lib be included right at build time? It's very bad to discover a crash at runtime and not at build time 😓
- Is it possible I'll have other similar surprises at runtime, or the fact that it properly imports nodegit is enough to be reassured about this?
