Of course I did not. It is the message you mentioned earlier that > started that (from Nagasayanam, V.S. on March 21st). The message is about > mozjs-60.8.0. And you can see that there is no mention of OSError.
Thanks. That was why it took me so long to originally find my notes (for which the key item to grep was OSError). I assumed it might have been trimmed off. > When trying today with host debian, I get: > ------------------ > 0:23.64 Creating config.status > 0:23.76 Traceback (most recent call last): > 0:23.76 File "/sources/firefox/firefox-68.6.0/configure.py", line 132, in > <module> > 0:23.76 sys.exit(main(sys.argv)) > 0:23.76 File "/sources/firefox/firefox-68.6.0/configure.py", line 43, in > main > 0:23.76 return config_status(config) > 0:23.76 File "/sources/firefox/firefox-68.6.0/configure.py", line 127, in > config_status > 0:23.76 return config_status(args=[], **encode(sanitized_config, > encoding)) > 0:23.76 File > "/sources/firefox/firefox-68.6.0/python/mozbuild/mozbuild/config_status.py", > line 132, in config_status > 0:23.76 reader = BuildReader(env) > 0:23.76 File > "/sources/firefox/firefox-68.6.0/python/mozbuild/mozbuild/frontend/reader.py", > line 854, in __init__ > 0:23.77 self._gyp_worker_pool = > ProcessPoolExecutor(max_workers=max_workers) > 0:23.77 File > "/sources/firefox/firefox-68.6.0/third_party/python/futures/concurrent/futures/process.py", > line 285, in __init__ > 0:23.77 EXTRA_QUEUED_CALLS) > 0:23.77 File "/usr/lib/python2.7/multiprocessing/__init__.py", line 218, in > Queue > 0:23.77 return Queue(maxsize) > 0:23.77 File "/usr/lib/python2.7/multiprocessing/queues.py", line 63, in > __init__ > 0:23.77 self._rlock = Lock() > 0:23.77 File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 147, > in __init__ > 0:23.77 SemLock.__init__(self, SEMAPHORE, 1, 1) > 0:23.77 File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 75, > in __init__ > 0:23.77 sl = self._semlock = _multiprocessing.SemLock(kind, value, > maxvalue) > 0:23.77 OSError: [Errno 13] Permission denied > 0:23.84 *** Fix above errors and then restart with\ > 0:23.84 "./mach build" > 0:23.84 make: *** [client.mk:115: configure] Error 1 > > So again different. OK, Every example mentions multiprocessing/synchronize.py near the end, but the exact details of the error message vary. I'll drop the and ending 'OSError: [Errno 38] Function not implemented' text. I guess debian is passing back -EPERM from an attempt to access shm, whereas when LFS is the host that gets replaced by Error 38. > Note that: > mount -t tmpfs devshm /dev/shm > cures the error > > Pierre I can settle for that, but was this build on sysvinit ? From xry111's reply, and your earlier points, I got the impression this is only a problem on BLFS sysvinit. If so, the Note should only be added in the sysvinit book. ĸen -- When alle is ſayed and all is done, ye must chooſe your faces wisely, for soon enouff ye will be playing with fyre."
