Hi ,

I am trying to build OPENLTE in MAC OS. but after the building, I try to  
launch the python script LTE\_fdd\_dl\_file\_gen.py" it always results fatal  
error:

Fatal Python error: PyThreadState\_Get: no current thread  
Abort trap: 6

I have looked through the internet, but it seems not so much valuable  
solution I can take a reference. Some answer explain that , this fatal  
error maybe caused by Dynamical library in MAC OS .

I have tried step by step to launch the command in Python:

the problem happened when :

```
 "import LTE_fdd_dl_fg"

```

I look how this file was build? in the link.txt

* * *

$ pwd  
/Users/wangsonghai/LTE/openlte\_v00-19-00/build/LTE\_fdd\_dl\_file\_gen/CMakeFiles/LTE\_fdd\_dl\_fg.dir

~/LTE/openlte\_v00-19-00/build/LTE\_fdd\_dl\_file\_gen/CMakeFiles/LTE\_fdd\_dl\_fg.dir  
$ ls -al link.txt  
-rw-r–r-- 1 wangsonghai staff 568 Nov 15 23:24 link.txt

* * *

I get the following command in link.txt

* * *

* * *

also, some notification from MAC OS :  
but it is too long to find the problem.
