Unable to compile on Fedora 35, possible glibc issue?

[katsucodes247]

I have glibc v2.34-11, running on Fedora 35. I've seen similar reports elsewhere but don't understand how to fix it.

I've followed the following steps but running make gives me the following error:

make[1]: Entering directory '/home/Documents/projects/bitcoin/btcdeb'
make[2]: Entering directory '/home/Documents/projects/bitcoin/btcdeb/secp256k1'
make[2]: Leaving directory '/home/Documents/projects/bitcoin/btcdeb/secp256k1'

Hi, thanks for the report!

Can you test #103 and see if that works for you?

Tested and it worked! Appreciate you fixing the issue so quickly.
