Bug

Status: Open (View Workflow)
-
Minor
-
Resolution: Unresolved
-
11.4.0
-
OS: Arch Linux (Manjaro)
Compiler: GCC 15.1.1
Build system: CMake + Ninja
libxml2 version: 2.14.3
MariaDB source branch: 11.4
Description
While building Mariadb with libxml2 development headers installed, a name conflict occurs between Mariadb's internal ElementType enum and predefined enum values in libxml/tree.h from libxml2.
This causes a build failure due to redefinition of constants like XML_DOCUMENT_TYPE_NODE, XML_DOCUMENT_FRAG_NODE, etc.
A possible solution is to Guard the enum definition using a more specific macro check to prevent conflict if libxml2 is included. Happy to submit a patch if needed.
