Just trying to obfuscate a custom python module with a config file in raspberry pi 4.
Module files obfuscated without problem, but failed to run module due to the following error.
** Same module obfuscated and run without any problem in windows 10.

RuntimeError: Call spp code out of pyarmor

-- version info --

PyArmor version : 7.7.3 (purchased version)

Could you test only a simple script in the raspi4?

Just for confirmation, obfuscating one simple print "hello world" script and run it in rasp pi4 with these commands

rm -rf dist
pyarmor obfuscate --advanced 2 --obf-mod 2 --obf-code 2 --wrap-mode 0 --exact foo.py
python dist/foo.py

It raise runtime error out of pyarmor.

Can not reproduced. It seems that using different pyarmor versions.

I also can reproduce this error on RaspberryPi 4. Obfuscating a single file works fine. However, obfuscating a project results in same error. I guess this is due to obfuscation messing up import procedure. My raspberry pi specs:

Raspbian GNU/Linux 11 (bullseye)
Linux raspberrypi 5.15.61-v7l+ #1579 SMP Fri Aug 26 11:13:03 BST 2022 armv7l GNU/Linux

I have prepared a minimal example below with structure:

main.py (not to be obfuscated)
lib (to be obfuscated)
 |__ foo.py
 |__ bar.py
 |__ __init__.py

and obfuscated with the command below:

pyarmor obfuscate --advanced 2 --obf-mod 2 --obf-code 2 --wrap-mode 0 --cross-protection 0 --restrict 0 --exact -r ./lib

After making sure pytransform.so is in path, i ran main.py(not obfuscated) and got the traceback:

Traceback (most recent call last):
  File "/home/usr/pyarmor/dist/main.py", line 6, in <module>
    from dist import print_hello, print_world
  File "</home/usr/pyarmor/dist/lib/__init__.py>", line 2, in <module>
  File "<frozen lib>", line 1, in <module>
RuntimeError: Call spp code out of pyarmor

The minimal example bundled below:

@Deahran got it, thanks. I'll check it. I verify it in linux.aarch64, not linux.armv7l

@Deahran I wonder do you test this in a clean machine? If not, please remove ~/.pyarmor/platforms and using Pyarmor 7.7.4 with core library r52.6, and try it again.

Okay, i'll let you know when i try.

Hello,

I've been able to obfuscate successfully with a fresh rpi image(link) on my raspberry pi 4, using pyarmor==7.7.4 with core library r41.15a since i could not figure out how to, but with a litte bit of workaround with odd issues.

Even though rpi4 uses ARM v8 processors, legacy images point to armv7l, which i showed in my previous post. With the newest 32-bit OS, it shows the processor info as:

Raspbian GNU/Linux 11 (bullseye)
Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux

I also verified that OS is 32 bit as well:

$ getconf LONG_BIT
32

On a fresh image, i built python3.9.15 from source, installed pyarmor==7.7.4 with pip. After, tried to obfuscate a single script but got the error:

Command line output

ERROR    /home/rdp/.pyarmor/platforms/linux/aarch64/3/_pytransform.so: wrong ELF class: ELFCLASS64

So it seems that pyarmor recognizes the processor bit size instead of OS and looking for 64 bit binaries. I manually downloaded armv7 binaries with pyarmor download linux.armv7 command and run the obfuscation command with the minimal example i've provided:

rdp@raspberrypi:~/programming/python/pyarmor_test $ pyarmor obfuscate --advanced 2 --obf-mod 2 --obf-code 2 --wrap-mode 0 --cross-protection 0 --restrict 0 --exact -r ./lib
ERROR    /home/rdp/.pyarmor/platforms/linux/aarch64/3/_pytransform.so: wrong ELF class: ELFCLASS64

and saw that pyarmor is still trying to use the wrong binaries. I manually copied /home/rdp/.pyarmor/platforms/linux/armv7/3/_pytransform.so from to /home/rdp/.pyarmor/platforms/linux/aarch64/3/_pytransform.so and rerun the command line and the obfuscation succeeded without errors. However, running the minimal example raised the same error:

Try to export PYARMOR_PLATFORM=linux.armv7 may fix the wrong platform

@jondy That did not fix the issue on rpi4. Pyarmor still fetches the wrong runtime (arm64 instead of arm7vl). However, manually generating runtime for armv7 and using that runtime solved the issue. Thanks.
