/usr/bin# python3 --version Python 3.5.5

I downloaded get-pip.py from https://bootstrap.pypa.io/pip/3.5/

How did you obtain and install Python?

georgewangchun commented 3 years ago

Th python3 is installed from our Yocto project. But it is not convenient for me to change the project configuration now. So I want to manually install pip.

I installed pip in the yocto image. now I got a different error:

/usr/bin# python qr.py Traceback (most recent call last): File "qr.py", line 2, in import pyzbar.pyzbar as pyzbar File "/usr/lib/python2.7/site-packages/pyzbar/pyzbar.py", line 7, in from .wrapper import ( File "/usr/lib/python2.7/site-packages/pyzbar/wrapper.py", line 143, in c_uint_p, # minor File "/usr/lib/python2.7/site-packages/pyzbar/wrapper.py", line 136, in zbar_function return prototype((fname, load_libzbar())) File "/usr/lib/python2.7/site-packages/pyzbar/wrapper.py", line 115, in load_libzbar libzbar, dependencies = zbar_library.load() File "/usr/lib/python2.7/site-packages/pyzbar/zbar_library.py", line 66, in load libzbar = cdll.LoadLibrary(path) File "/usr/lib/python2.7/ctypes/init.py", line 444, in LoadLibrary return self._dlltype(name) File "/usr/lib/python2.7/ctypes/init.py", line 366, in init self._handle = _dlopen(self._name, mode) OSError: /usr/lib/libzbar.so.0: undefined symbol: dsprintbuf

georgewangchun commented 3 years ago

in zbar\decoder\ean.c

ifdef DEBUG_EAN

static unsigned char debug_buf[0x18];

static inline const unsigned char dsprintbuf(ean_decoder_t ean) ...

But when dsprintbuf() is called it is not wrapped in #ifdef DEBUG_EAN

The issue doesn't seem related toget-pip.py anymore.
