pyuv fails to build on Windows with Python 3.3,about saghul/pyuv

saghul commented on August 11, 2024

I don't have a Windows machine here right now, can you please try the following? Replace this line: https://github.com/saghul/pyuv/blob/master/setup_libuv.py#L119 with:

exec_process(b'cmd.exe /C vcbuild.bat release', cwd=self.libuv_dir, env=env, shell=True)

and this line: https://github.com/saghul/pyuv/blob/master/setup_libuv.py#L131 with

exec_process(b'cmd.exe /C vcbuild.bat clean', cwd=self.libuv_dir, shell=True)

from pyuv.

saghul commented on August 11, 2024

Basically it's just adding the "b" in front, thus making it a bytes object which does support the buffer API.

from pyuv.

pfmoore commented on August 11, 2024

Fixing exec_command is messier than that. Making the command a bytes object just messes up stuff elsewhere :-( I don't have a complete fix, but I did manage to hack it to tell me what's really wrong, which is that vcbuild.bat isn't present in Visual Studio 2010, which is used for Python 3.3.

It's not at all obvious to me how to fix the build process for libuv to use VS2010, so I can't really take this much further. And I'm not sure how helpful it would be to try to properly address the various bytes/string issues in exec_command if the build is just going to fail anyway...

vcbuild.bat is included in libuv, it's not taking it from the system. Or do you mean other vcbuild.bat? Can you please paste the output of the command when it failed? You can add silent=False to the exec_process call to see the full output.

It will try to use different VS2010 and it it's not available fallback to 2008, so if you have 2010 installed you should be fine.

My apologies - I was misremembering the VC command names.

I'll try to set up a proper test in the next few days. A big part of the
problem is likely to be that I have a fairly unusual build environment - I
run Powershell as my main shell, and don't have Visual C in my PATH. This
does not harm standard distutils, as it does not rely on cmd.exe
functionality, and it gets the location of Visual C from the registry, but
it is prone to cause problems for more complex build setups.

I'll try two approaches to isolate the problem - I will run in my normal
environment adding silent=False and working round the str/bytes issues as
above, and I'll also set up a more conventional build environment (VC on
the PATH using cmd.exe) and see how that works. My build environment is on
a different system, though, so it may take me a couple of days to report
back.

saghul commented on August 11, 2024

I see. I'll try to setup a test environment as well. Hopefully we can get to the bottom of this :-)

from pyuv.

saghul commented on August 11, 2024

You may want to hold the testing for now. I managed to get an environment for this, and things are a mess, to say the least. libuv uses gyp to generate the build files, but gyp itself is written in Python but it doesn't support Python 3. I managed to get around that by manually modifying some files, bus VS2010 seems to be very picky about variable declaration and initialization, I'll fix this and drop a line around here once it's done.

from pyuv.

saghul commented on August 11, 2024

Ok, I managed to get it working, sort of. pyuv compiles, but you'll need to have Python 2 installed and modify vcbuild.bat from deps/libuv to use it, in order for GYP to work. Yes, it's a mess but right now I don't know a better solution...

from pyuv.

saghul commented on August 11, 2024

Hum, I guess I could add a patch only for Windows and if Python 3 is used, but the path would be hardcoded to C:\Python27\python.exe

from pyuv.

schlamar commented on August 11, 2024

I would say this patch is fine for developer releases, while for a stable release you could include the already generated project files for VS 2008 and VS 2010 and just pick the right one depending on the interpreter.

from pyuv.

saghul commented on August 11, 2024

The problem is that GYP doesn't generate generic project files, they are either Debug or Release and arch specific.

Ideally libuv (or pyuv) should contain a VS project file to avoid using GYP altogether, since it's a no-go on Python 3 at the moment... :-S

from pyuv.

schlamar commented on August 11, 2024

@pfmoore The bytes/string issue should be fixed by #82 so you should get a proper error message from executing vcbuild.bat.

from pyuv.

schlamar commented on August 11, 2024

Update: The build succeeds if python in PATH is pointing to 2.6 or 2.7 and setup.py is executed with a Python 3 version.

from pyuv.

schlamar commented on August 11, 2024

I made an upstream report for this: joyent/libuv#723

from pyuv.

saghul commented on August 11, 2024

Great! I added some feedback there :-)

from pyuv.

saghul commented on August 11, 2024

Providing a PYTHON env variable as an override and setting it to an appropriate value from setup_libuv.py seems like the way to go. Are you willing to provide such a patch for libuv? Otherwise I'll add it to my TODO list :-)

from pyuv.

schlamar commented on August 11, 2024

joyent/libuv#725

from pyuv.

saghul commented on August 11, 2024

Awesome!

from pyuv.

saghul commented on August 11, 2024

It landed on libuv master, great!

from pyuv.

saghul commented on August 11, 2024

Not to put any pressure or anything :-) but are you planning to send a pull request with a fix for this? Otherwise I'll work on the fix myself. I thought I'd ask, since you have been doing some great work on the Windows side recently and I want to avoid doing duplicated work.

from pyuv.

schlamar commented on August 11, 2024

What do you even propose as solution? :)

from pyuv.

saghul commented on August 11, 2024

Check if %SYSTEMDRIVE%\Python26\python.exe or %SYSTEMDRIVE%\Python27\python.exe exist and if so set the PYTHON env variable, else raise an exception asking the user to either export the PYTHON env variable or install Python 2.

from pyuv.

schlamar commented on August 11, 2024

Alright, I will look into it tomorrow. In the meantime you could upgrade libuv so PYTHON will be understood :)

from pyuv.

saghul commented on August 11, 2024

Done in 2e5be78, all yours ;-)

from pyuv.

pfmoore commented on August 11, 2024

Still not working for me (Python 3.3, with PYTHON set to the directory of a Python 2.7 interpreter)

There is no Release folder in deps/libuv. And there's no build log for libuv anywhere that I can see :-(

schlamar commented on August 11, 2024

@pfmoore PYTHON must point to the executable.

from pyuv.

schlamar commented on August 11, 2024

@pfmoore And make a rm -rf deps. If gyp fails the libuv directory isn't in a clean state anymore.

schlamar commented on August 11, 2024

@pfmoore If both does not work execute vcbuild.bat directly to debug it.

Odd as libuv.lib is in the link. Could it be because I'm on 64 bit Windows? Or because Python 3.3 uses VS10? These seem unlikely, but I can't see anything obvious...

Are you using a 64bit Python?

from pyuv.

pfmoore commented on August 11, 2024

Yes.

from pyuv.

saghul commented on August 11, 2024

Heh, this is a known issue. I plan to solve it tonight. Can you test this:

Edit setup_libuv.py and replace this line

https://github.com/saghul/pyuv/blob/master/setup_libuv.py#L162

with:

exec_process(['cmd.exe', '/C', 'vcbuild.bat', 'x64', 'release'], cwd=self.libuv_dir, env=env, shell=True)

from pyuv.

schlamar commented on August 11, 2024

@saghul Solved :)

from pyuv.

pfmoore commented on August 11, 2024

Builds and works fine now. Many thanks!

from pyuv.

saghul commented on August 11, 2024

Glad to hear! Thanks guys!

from pyuv.

schlamar commented on August 11, 2024

There is still one issue: We don't get any error if vcbuild.bat fails. This should be fixed with: joyent/libuv#727

from pyuv.

saghul commented on August 11, 2024

No problem, I'll bump the revision on pyuv once it's merged.

from pyuv.

schlamar commented on August 11, 2024

@pfmoore Could you upload a 64bit build of pyuv 0.9.7 (for Python 3) somewhere? I can't build 64bit because I have only VS Express, but I really would like to test it. Thanks a lot 🍰

from pyuv.

pfmoore commented on August 11, 2024

Just tried and it broke with the following:

>python .\setup.py bdist_wininst
running bdist_wininst
running build
running build_ext

Hope this helps - sorry, but I don't have any time to diagnose further.

saghul commented on August 11, 2024

@pfmoore a libuv revision bump fixes this. I'll bump it later today.

from pyuv.

schlamar commented on August 11, 2024

@pfmoore Running it a second time should succeed, though. The linked libuv revision has only some build issues with tests.

from pyuv.

schlamar commented on August 11, 2024

I meant python setup.py ... :)

from pyuv.

pfmoore commented on August 11, 2024

OK, worked now. I have a wininst exe for Python 3.3, 64-bit. I don't have any public space to upload to, can you suggest somewhere I can put it?

from pyuv.

schlamar commented on August 11, 2024

You could create an issue with attachment here: https://code.google.com/p/pyuv/issues/list

Or just push it into a GitHub repo/branch if you don't have a Google account (you can delete it after I downloaded it)

Thanks for your effort 👍

from pyuv.

pfmoore commented on August 11, 2024

Uploaded as issue 1 to google code.

from pyuv.

schlamar commented on August 11, 2024

Thanks 👍
