How to handle multiple glibc versions?

[hexclann]

I'm compiling the bash script in a machine, I want to use it different OS, but not all the OS has the same glibc version so the binary will fail with a message :

./myscript: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by ./myscript)

I'm compiling the shell script with the command - shc -U -r -f myscript.sh -o myscript

How to make my script to compatible with multiple OS?

try CFLAGS="-static" shc -U -r -f myscript.sh -o myscript

glibc-static package need to be installed on a Fedora base OS. I think this issue can be closed.

Well , we have the same problem :

• compile a simple script with shc -f ekidw.sh -r -o ekidw on Ubuntu 22.04
• Result complains that GlibC not found on Ubuntu 20.04

We should find a way to maximize portability across generation of distribution

CFLAGS="-static" solved it for me. Now I can compile in Ubuntu 22.04 and run in Ubuntu 20.04. Thanks @RandomOS!

PS: should work for you too, @freechelmi.
