global name 'zmq' is not defined

[M-Marz]

Hi,

I`m trying to install Sublime-IJulia and I´m running into troubles. I read a couple of related threads but I couldn´t find a solution...

I added ZMQ and IJulia. ZMQ built successfully IJulia not, since I don´t have IPhython installed.
This is my settings file:

"windows": {
"zmq_shared_library": "C:\Users\acer-touch.julia\v0.3\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin\libzmq.dll",
"commands": [
{
"command_name": "default",
"julia": ""C:\Users\acer-touch\AppData\Local\Julia-0.3.6\bin\julia.exe"",
"julia_args": "",
"ijulia_kernel": "~/.julia/v0.3/IJulia/src/kernel.jl"
}
]
}
}

If I run "Sublime-IJulia: Open New IJulia Console", I get the following:

Starting IJulia backend...
Command Executed: "C:\Users\acer-touch\AppData\Local\Julia-0.3.6\bin\julia.exe" C:\Users\acer-touch/.julia/v0.3/IJulia/src/kernel.jl "C:\Users\acer-touch\AppData\Roaming\Sublime Text 3\Packages/User/profile-19.json"
Traceback (most recent call last):

self.ptr = zmq.zmq_ctx_new()
NameError: global name 'zmq' is not defined

My paths should be correct and I used absolute paths...
What is wrong?

Thank´s a lot for any help!

It looks like it's not finding your ZMQ library. First I would try restarting sublime, since the ZMQ library is opened/located when sublime starts. If it's not found when you restart sublime, it should popup and tell you. You'll then want ot fire up Julia and run using ZMQ; ZMQ.zmq and copy the resulting path to your ZMQ library into the zmq_shared_library command in your Sublime-IJulia settings. I think your Julia command path doesn't need the extra quoting either, just "C:\Users\acer-touch\AppData\Local\Julia-0.3.6\bin\julia.exe" should be sufficient.

[M-Marz]

I deleted the extra quoting and did using ZMQ; ZMQ.zmq; the resulting path is the one I used in the settings file:
"C:\Users\acer-touch.julia\v0.3\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin\libzmq.DLL"

When I restart Sublime the following error pops up:
plugin_host.exe Entry Point Not Found
The procedure entry point "_ZSt24_throw_out_of_range_fmtPKcz" could not be located in the dynamic link library "C:\Users\acer-touch.julia\v0.3\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin\libzmq.DLL"

It looks as if I made a typo, but I checked it 1000times..

Hmmm....that's a pretty weird error. It almost seems like your library is out of date or something, but that shouldn't be the case when it's being installed automatically. Hmmm, I'll have to brainstorm some other things to try.

Same error, different lib:

---------------------------
plugin_host.exe - Entry Point Not Found
---------------------------
The procedure entry point _ZSt24__throw_out_of_range_fmtPKcz could not be located in the dynamic link library libstdc++-6.dll. 

Also, this S.O. question?

[tildebyte]

Answering my own question:
libstdc++-6.dll exists in 2 places: Sublime Text 3 Beta\Data\Packages\IJulia\windeps and .julia\v0.3\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin.
i.e., the version shipping with the plugin doesn't match the one libzmq is linked against. I fixed it by copying down ZMQ's libstdc DLL from mingw\bin into the plugin's windeps dir.
So, yes, I concur: @M-Marz libzmq is probably mismatched to the plugin OR he's got another libzmq somewhere in the path, which ST is finding first.

@tildebyte That works! Thank you very much!

[Ken-B]

@tildebyte same problem here, I removed the dll in windeps and now it works, thanks a lot for the fix!

[androdri1]

@tildebyte same proble, same solution. Thanks!

[nickleeh]

@tildebyte I got the same problem, when I copy the libstdc++-6.dll to the sublime deps, I got kernel died. Any clue?

[sanghmitragautam]

@tildebyte same problem, solution worked Thank you!

[denniscote-work]

@tildebyte same problem. My windeps dir was in a different location, but copying the mingw32 libstdc++-6.dll file there worked. Thanks.
