Dears,
This is the release I try to test it for QUIC protocol: quic-dev-20210413-quic-rebased
When compiling it without quic it compiled an run correctly, and show the version: haproxy version is 2.4-dev16-aba24570
But with quic it give compile error as follow:
#make TARGET=linux-glibc USE\_OPENSSL=1 USE\_ZLIB=1 USE\_PCRE=1 USE\_SYSTEMD=1 USE\_QUIC=1

make: \*\*\* [Makefile:932: src/ssl\_sample.o] Error 1
Also I need any docs/hint about quic configuration.
Your help please.
Thank you.

you have to compile quictls.

as zino said: quictls is essential, also i think you should use haproxy 2.6.x as this versions comes with a (near production final) release quic. i think 2.4 was experimental
