Issue ID: 10011
Summary: Incompatibilities with stricter C99 compilers
Product: OpenLDAP
Version: 2.6.4
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal
Priority: ---
Component: build
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Newer C compilers (>= Clang 16 and likely >= GCC 14) reject some constructs
removed in C99 like implicit function declarations and implicit ints. Some
compilers are also starting to reject obsolete K&R prototypes which were
removed in C23.
I've filed an MR at
https://git.openldap.org/openldap/openldap/-/merge_requests/605 to address the
issues in configure as well as a small number of issues in the codebase itself.
