Title: Windows bug Post by: bvdp on July 12, 2019, 04:30:47 PM If you are running MMA on a windows OS you will have a minor problem in that the module fcntl doesn't exist on it. To fix, just do the following:
1. In the file common.py delete line 34: import fcntl 2. Replace line 63 in common.py with: try: # Windows doesn't know about fcntl and doesn't need it. import fcntl fcntl.flock(opath, fcntl.LOCK_EX) # make sure we print in one batch except: pass For the curious: the fcntl.flock() sets up a lock so that only one process can write to the output file. This is the file used for reporting warnings, etc. if the environment variable MMA_LOGFILE is set. By wrapping it all in a try/except it all works ... just no file lock on windows. The next developer release will include this patch. |
