Does it support the type like "unsigned char *"?

[hideinhat]

Hi, Thank you for your awesome work.
I have a question, does it support the type like "unsigned char *" , I test in ctypes, "unsigned char *" can be indicated as "ctypes.POINTER(ctypes.c_ubyte)" ,is that the same in zugbruecke?

[s-m-e]

Basically zugbruecke is identical to ctypes most of the time, i.e. a "drop-in replacement". In some cases, additional directives might be required for Memory Synchronization.

Thank you for timely reply.
I installed zugbruecke and wine. But when I run wenv init , an error happend:
wenv init wine: configuration in L"/home/admin/anaconda3/envs/py38/share/wenv/win32" has been updated.

Could you please help to fix this error?

What happens if you simply run wenv --help and wenv python --version on the command line (with your py38 environment activated)?

What happens if you simply run wenv --help and wenv python --version on the command line (with your py38 environment activated)?

I run wenv --help and wenv python --version on the command line, it shows the following message:

The version of Python in wenv is 3.7.4, which is not match with Python in my py38 environment.
I googled ConnectionRefusedError: [Errno 111] Connection refused, some suggests to check host and port which is listening on, but I don't know which host and port are used by the server and client.
It is also said that the connection may be blocked by a firewall.
I have no idea how to troubleshoot this problem.

Ok, wenv works as expected, which also means that Wine is working. That's a good start.

This is expected.

[... ] some suggests to check host and port which is listening on, but I don't know which host and port are used by the server and client.
It is also said that the connection may be blocked by a firewall.

zugbruecke has two components: The Unix Python interpreter, running on your Linux system, acting as a client, and a Windows Python interpreter, running on Wine, acting as the server (plus a second connection in reverse, but that's not causing the failure in your case). The host is localhost, i.e. your machine. There is no connection to the outside world. The (two) ports are chosen more or less at random, see here and here. For debugging, you could theoretically overwrite the calls to get_free_port and set those values to integers of your choice. Make sure they are free ports and greater than 1024. It's unlikely a firewall issue though it can be, so checking its configuration might be worth it, too.

Besides, you can set the version of the Windows Python interpreter to something more recent, say a 3.8 or 3.9, via the pythonversion parameter, see here. Sometimes this does the trick.

For further debugging: What Linux distribution/version is this (lsb_release -a)? All flavours of Fedora/CentOS/RedHat and older versions of Debian/Ubuntu (predating 2018) are known to cause issues.

What version of Wine (wine --version)? Distribution packages are known to cause issues - packages from the Wine project directly usually work better.

Thanks a lot for your response.
At first, I run wenv clean then overwrite the calls to get_free_port according to your instructions and set port values to integers as 5400,5405.

[...]
# from .lib import get_free_port
from .typeguard import typechecked
import socket

# WINE PYTHON INTERPRETER CLASS

@typechecked
def get_free_port() -> int:

    s = socket.socket()
    s.bind(("", 5405))
    port = s.getsockname()[1]
    s.close()

    return port

@typechecked
class Interpreter(InterpreterABC):

It still shows that error above when I run wenv init.
And I'm going to set the version of the Windows Python interpreter,find the following code in two places (~/anaconda3/envs/py38/lib/python3.8/site-packages/zugbruecke/core/config.py and ~/anaconda3/envs/py38/lib/python3.8/site-packages/wenv/_core/config.py),

if key == "pythonversion":
            return PythonVersion(self['arch'], 3, 7, 4, 'stable')  # Define Wine-Python version

I modified PythonVersion(self['arch'], 3, 8, 12, 'stable') which is in ~/anaconda3/envs/py38/lib/python3.8/site-packages/zugbruecke/core/config.py, then run wenv init and wenv python --version, the ConnectionRefusedError is still there and the version of the Windows Python interpreter also does not change to 3.8.12.
then I also modified PythonVersion(self['arch'], 3, 8, 12, 'stable') which is in ~/anaconda3/envs/py38/lib/python3.8/site-packages/wenv/_core/config.py, after I run wenv init and wenv --help, another error happend and Windows Python interpreters is not installed.

It still shows that error above when I run wenv init.

I misread you initial issue - it looked very similar to something that I had seen before many times due to the lack of formatting, but it is different.

wenv fails to connect to the internet (!) to collect the Python interpreter itself, which causes wenv init to fail. Either it's a connectivity issue or, more likely, you are trying to use a version that is unavailable as a "Windows embeddable package" as required by wenv and zugbruecke. The last point release of Python 3.8 for which this is available is 3.8.10, see here. Subsequent releases are missing those builds, see here.

pythonversion is actually a configurable parameter in zugbruecke (other than the ports). You can set it as a configuration parameter. If you want to go for 3.8, set it to 3.8.10 (stable).

[hideinhat]

Thank you for responsing.
I tried to change the version of Python to 3.8.10 in conda environment and set pythonversion by ZUGBRUECKE_PYTHONVERSION=3.8.10.
ConnectionRefusedError still there.
I run wenv python --version, it returns Python 3.7.4.
Is that the right way to set pythonversion?
