[FLASH-USERS] FLASH's python tools

[Ryan Farber]

Hi Ong,

Unfortunately, I appear to have deleted my FLASH 4.6.2 installation. I had
thought it should be fine with python3 but can't confirm at this time.
However, the user guide suggests python3 compatibility since FLASH 4.6 as I
had thought so perhaps there is some improper link for the download of
FLASH 4.6.2 pointing to an older version?
http://flash.uchicago.edu/site/flashcode/user_support/flash4_ug_4p62/node6.html

Regarding the flmake lines in the user guide, where do you see that? I
haven't used that tool before. I don't see flmake referenced in the
quickstart guide (just double-checked)
http://flash.uchicago.edu/site/flashcode/user_support/flash4_ug_4p62/node13.html
.

If you don't require FLASH 4.6.2 you can see if FLASH4.6 setup works with
your python3 environment (there shouldn't be those diamond operators except
in older version of FLASH). However, I'm pretty sure python 2.7 will work
if you don't use flmake since the error you reported had to do with that
tool.

Best,
--------
Ryan
