Bug ID: 104654
Summary: Errors in gthread.d when building against MinGW-w64
with --enable-threads=posix
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: brechtsanders at users dot sourceforge.net
Target Milestone: ---
When building GCC (recently tried 11.2 snapshot 20220219) against MinGW-w64
with --enable-threads=posix the following D compiler errors occur:
r:\winlibs64-11.2.0ucrt\gcc-11-20220219\libphobos\libdruntime\gcc\gthread.d:46:30:
error: undefined identifier 'PTHREAD_ONCE_INIT', did you mean variable
'GTHREAD_ONCE_INIT'?
46 | enum GTHREAD_ONCE_INIT = PTHREAD_ONCE_INIT;
| ^
r:\winlibs64-11.2.0ucrt\gcc-11-20220219\libphobos\libdruntime\gcc\gthread.d:44:29:
error: undefined identifier 'pthread_key_t'
44 | alias __gthread_key_t = pthread_key_t;
| ^
r:\winlibs64-11.2.0ucrt\gcc-11-20220219\libphobos\libdruntime\gcc\gthread.d:45:30:
error: undefined identifier 'pthread_once_t'
45 | alias __gthread_once_t = pthread_once_t;
| ^
>From what I gather things like pthread_key_t and pthread_once_t should probably
be defined in libphobos/libdruntime/core/sys/posix/sys/types.d and
PTHREAD_ONCE_INIT in libphobos/libdruntime/core/sys/posix/pthread.d
I noticed in libphobos/libdruntime/core/sys/posix/sys/types.d there is no
specific version() case for Windows/MinGW with POSIX threads.
