GLIBC_2.18 not found (uws_linux_x64_72.node)

[codermapuche]

Hello when i try to use it, throw this error:

Error: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /home/uws/node_modules/uWebSockets.js/uws_linux_x64_72.node)

when i run:

ldd --version
ldd (GNU libc) 2.17

Is possible compile with 2.17? Is a dedicated server and can't change the entire operative system (CENTOS) or install 2.18 and run both.

How i can do it?

Thanks!

It looks like provided binaries depend on glibc 2.18 from 2013 - that seems alright. If you want to recompile for older versions you're on your own (this also applies to people wanting Alpine Linux binaries - same story).

Building for CentOS.

1. Install gcc that supports C++17 (you can see if required version changes in build.c file). I've built uWebSocketsjs 0.16 with gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)
2. In build.c under /* Linux */ change clang and clang++ to gcc and g++
3. Grab uWebSocketsjs. If referenced repos with uWebSockets and uSockets didn't load - grab them too.
4. Follow general building from source based on makefile
5. From uws/dist/ grab addons with js file and drop into your projects node_modules/uWebsocketsjs/
6. Enjoy fast http/ws server.

I have built a custom binary (and tutorial) that will solve your exact problem. Hope it helps!
