Cython.Compiler.Errors.CompileError: psrdada/reader.pyx

we build the psrdada_python in the ubuntu22 ,python3.10,but met some problmes, resolve it by:
1，cd psrdada
modified dada_hdu.pxd
ctypedef unsigned long int uint64_t
to
cdef extern from "stdint.h":
ctypedef unsigned long int uint64_t

ctypedef unsigned long key_t
to
cdef extern from "stdint.h":
ctypedef unsigned long key_t
2,
modified the setup line 1 to #!/usr/bin/env python3

3，cd psrdada
python3 -m cython *.pyx
cd ..
make

Thanks for reporting the issue!
I tried installing on my laptop (Fedora 39, python 3.12). I had to fix some errors with cython not finding dada_hdu.pxd, but i cannot reproduce your error. Can you try again with current master version, and copy-paste the error in more detail?

To respond to your points:

1. The first change seems reasonable: 'unsigned long int' is defined in 'stdint.h' on my system. The 'key_t' supposedly comes from "sys/ipc.h" -- see 'man ftok', so i prefer to get it from there instead.
2. seems reasonable, i've changed the #! env line in setup to python3.

I've created a new branch can you see if that works?
