Re: [libvirt] [PATCH] build: fix build with newer gnutls

Building with gnutls 3.2.0 (such as shipped with current cygwin) fails with: rpc/virnettlscontext.c: In function 'virNetTLSSessionGetKeySize': rpc/virnettlscontext.c:1358:5: error: implicit declaration of function 'gnutls_cipher_get_key_size' [-Wimplicit-function-declaration] Yeah, it's stupid that gnutls broke API by moving their declaration into a new header without including that header from the old one, but it's easy enough to work around, all without breaking on gnutls 1.4.1 (hello RHEL 5) that lacked the new header. * src/rpc/virnettlscontext.c (includes): Include additional header. * configure.ac (gnutls): Check for <gnutls/crypto.h>. Signed-off-by: Eric Blake <eblake(a)redhat.com&gt; --- Pushing under the build-breaker rule, once my testing completes across multiple systems with various gnutls versions (1.4.1 in RHEL5, 2.12.23 in Fedora 18, 3.2.0 in Cygwin).
