Bug ID: 114866
Summary: <memory> & out_ptr in freestanding
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: weidmann at acm dot org
Target Milestone: ---
With gcc version 14.0.1 20240411 (Red Hat 14.0.1-0) (GCC) on x86_64 GNU/Linux.
Using the following command options:
g++ -std=c++23 -fno-rtti -fno-exceptions -fno-non-call-exceptions
-fno-unwind-tables -fno-use-cxa-atexit -fno-enforce-eh-specs -faligned-new
-fsized-deallocation -fpermissive -m32 -ffreestanding -fomit-frame-pointer
-Os -fno-asynchronous-unwind-tables -fno-builtin -Wall -fanalyzer
I get the following error:
In file included from /usr/include/c++/14/memory:95,
...
/usr/include/c++/14/bits/out_ptr.h:57:22: error: ‘__is_shared_ptr’ was not
declared in this scope

Is #if _GLIBCXX_HOSTED missing around
#if __cplusplus > 202002L
# include <bits/out_ptr.h>
#endif
> As a quick workaround for building my project, I define #define
> _GLIBCXX_OUT_PTR_H before including <memory>
