[Openvpn-devel] [ovpn-dco] It seems not to compile ovpn-cli successfully

???? Tue, 17 Nov 2020 18:33:29 -0800

Hi Antonio, Lev,


&nbsp;I'm a end user of OpenVPN. I have been paying close attention to any 
solution that makes OpenVPN data channel running in the kernel space.
Many thanks to you bringing ovpn-dco finnaly out. Can not wait to have a try. 
So I tried compiling it. Kernel module is OK to compile without
issues in my Ubuntu 18.04 PC, but&nbsp; it seems not to compile ovpn-cli 
successfully. I did not see OVPN_CIPHER_ALG_CHACHA20POLY1305
is defined. Did I miss to install some header files or lib?
