From 34378a4ac257f2f5fcf364786d1634a8c36b304f Mon Sep 17 00:00:00 2001 Message-ID: <34378a4ac257f2f5fcf364786d1634a8c36b304f.1701158114.git.mprivozn@redhat.com> From: Michal Privoznik Date: Mon, 27 Nov 2023 15:04:43 +0100 Subject: [PATCH 1/2] Make xmlError structs constant In libxml2 commits v2.12.0~14 and v2.12.0~77 the API changed so that: 1) xmlGetLastError() returns pointer to a constant xmlError struct, and 2) xmlSetStructuredErrorFunc() changed the signature of callback (validate_structured_error_nop()), it too is passed pointer to a constant xmlError struct. But of course, older libxml2 expects different callback signature. Therefore, we need to typecast it anyway. Also, drop obviously incorrect @error annotation in validate_structured_error_nop; the variable is used.
