Subject: [PATCH] build: Move to minimum gnutls >= 3.5.18

This version matches current qemu.
|
|
|
|
RHEL 7 gnutls is too old (lacks gnutls_session_set_verify_cert), which
|
|
means TLS will be disabled on this platform. RHEL 8 has gnutls 3.6.14.
|
|
|
|
I also unconditionally enabled the gnutls/socket.h header. This
|
|
header was added in 2016 (gnutls 3.5.3), so it's not present in RHEL 7.
|
|
|
|
On RHEL 7 the configure-time test now prints:
|
|
|
|
checking for GNUTLS... no
|
|
configure: WARNING: gnutls not found or < 3.5.18, TLS support will be disabled.
|
|
...
|
|
Optional library features:
|
|
TLS support ............................ no
