#include "crypto/tlscreds.h"
crypto: Make QCryptoTLSCreds* structures private Code consuming the "crypto/tlscreds*.h" APIs doesn't need to access its internals. Move the structure definitions to the "tlscredspriv.h" private header (only accessible by implementations). The public headers (in include/) still forward-declare the structures typedef. Note, tlscreds.c and 3 of the 5 modified source files already include "tlscredspriv.h", so only add it to tls-cipher-suites.c and tlssession.c. Removing the internals from the public header solves a bug introduced by commit 7de2e856533 ("yank: Unregister function when using TLS migration") which made migration/qemu-file-channel.c include "io/channel-tls.h", itself sometime depends on GNUTLS, leading to a build failure on OSX: [2/35] Compiling C object libmigration.fa.p/migration_qemu-file-channel.c.o FAILED: libmigration.fa.p/migration_qemu-file-channel.c.o cc -Ilibmigration.fa.p -I. -I.. -Iqapi [ ... ] -o libmigration.fa.p/migration_qemu-file-channel.c.o -c ../migration/qemu-file-channel.c In file included from ../migration/qemu-file-channel.c:29: In file included from include/io/channel-tls.h:26: In file included from include/crypto/tlssession.h:24: include/crypto/tlscreds.h:28:10: fatal error: 'gnutls/gnutls.h' file not found #include <gnutls/gnutls.h> ^~~~~~~~~~~~~~~~~ 1 error generated.
