OpenVPN Support Forum

When installing openvpn-2.5.6 running ./configure produced an error. Output of terminal and relevant section of config.log attached.

I have a Gigabyte B560M board and Intel series 11 i5 cpu running Linux Mint Una with kernel 5.13.0.37

I cannot install the files it seems to be complaining about - Scrt1.o, crti.o

Assistance would be appreciated

Don't use sudo

Always build with a user account.

Thanks TinCanTech

Tried that with the same result. config-log has more info this time - please see below.

Looks sort-of fatal ..

This is how I am compliling Openvpn 2.7 on unbutu 18 if you like you can try it .

Hi,

This topic is now 6 months old.
TS is on Ubuntu 20.04.3 (LM Una) and I presume TS has found a solution by now.
I have little experience building from source but a bit of search suggests some packages you listed are not needed, did not verify that though.
