Bug ID: 95545
Summary: thread:: conflicts with std::thread
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: dje at gcc dot gnu.org
Target Milestone: ---
AIX, MSVC, and possibly other systems, implemented their own definition of
thread different from Posix threads.
libstdc++ <thread> header eventually includes <gthr-posix.h>, which includes
the system <pthread.h> header, which, on AIX, eventually includes
<sys/thread.h>
The AIX header nicely does
#ifdef __cplusplus
extern "C" {
#endif
struct thread {
...
}
which creates an ambiguity when a user references thread:: without std::thread.
LLVM C++ has a pattern that helps to avoid the conflict because of a similar
problem for MSVC:
namespace llvm {
typedef std::thread thread;
}
llvm/include/llvm/Support/thread.h
Would libstdc++ consider a similar solution?
