Jones" Errors-To: qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Sender: "Qemu-devel" From: "Richard W.M. Jones" According to the gcrypt documentation it's intended that gcry_check_version() is called with the minimum version of gcrypt needed by the program, not the version from the header file that happened to be installed when qemu was compiled. Indeed the gcrypt.h header says that you shouldn't use the GCRYPT_VERSION macro. This causes the following failure: qemu-img: Unable to initialize gcrypt if a slightly older version of libgcrypt is installed with a newer qemu, even though the slightly older version works fine. This can happen with RPM packaging which uses symbol versioning to determine automatically which libgcrypt is required by qemu, which caused the following bug in RHEL 8: https://bugzilla.redhat.com/show_bug.cgi?id=1840485 qemu actually requires libgcrypt >= 1.5.0, so we might put the string "1.5.0" here. However since 1.5.0 was released in 2011, it hardly seems we need to check that. So I replaced GCRYPT_VERSION with NULL. Perhaps in future if we move to requiring a newer version of gcrypt we could put a literal string here. Signed-off-by: Richard W.M. Jones Signed-off-by: Daniel P.
