ullebe1 opened a new issue, #284:
URL: https://github.com/apache/pulsar-client-node/issues/284
Running this on Debian Buster (which is EOL, but this issue should manifest
itself on RHEL 8 too as it also has a too old `libstdc++`) by doing `npm
install pulsar-client` as documented in the Readme currently fails with the
following error message:
```
Error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26’

```
This is because the version of `libstdc++` it has is too old. Upgrading to
Debian Bullseye solves the problem as it has a newer version of `libstdc++`.
Per the GCC [docs](https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html)
`GLIBCXX_3.4.26` is available from GCC 9.1.0 (and its `libstdc++`), so having
this documented as the minimum required version would be nice.
---
Poking around I can see that the bundled static library dynamically links
against several other libraries (this is for the version installed when using
Debian Bullseye):
```
root@585a6dfd04d5:/app/node_modules/pulsar-client/lib/binding# ldd
Pulsar.node
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
(0x0000004002194000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x0000004002363000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
(0x00000040024a7000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00000040024c1000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00000040024e3000)
/lib64/ld-linux-x86-64.so.2 (0x0000004000000000)
```
Perhaps documenting the minimum version of those too would be nice?
---
An alternative could be to not dynamically link any dependencies at all, but
I do not know how feasible that is.
