libassuan 3.0.1: putc_unlocked() is re-defined unconditionally
Closed, ResolvedPublic
Actions

Description

In src/assuan-defs.h, putc_unlocked() is re-defined unconditionally, because the presence of putc_unlocked() is never determined in configure.

#ifndef HAVE_PUTC_UNLOCKED
int putc_unlocked (int c, FILE *stream);
#endif

That leads to duplicate symbol '___sputc' while linking on macOS.

I propose this fix:

--- configure.ac.orig	2024-08-09 11:58:20.924113872 +0000
+++ configure.ac

Actually we should get rid of stdio functions and use the es_foo replacements from libgpg-error.
