Compile Python2 codes into binary in openwrt19.07

Hi,

I try to use Nuitka to convert Python2.7 codes into binary in openwrt, but it always fails with the following information:

Nuitka:WARNING:Not recursing to 'Crypto' (/usr/lib/python2.7/site-packages/Crypto), please specify --nofollow-imports (do not warn), --follow-imports (recurse to all), --nofollow-import-to=Crypto (ignore it), --follow-import-to=Crypto (recurse to it) to change.

collect2: error: ld returned 1 exit status

scons: *** [/mnt/sd01/pycharm_project1/main_th.bin] Error 1

anyone who knows about this error or who uses Nuitka before in openwrt to convert Python2 into binary?

thanks
