creates a not loadable module for node-serialport

[davibe]

I am using nw-gyp on windows with configure --target=0.5.0 to build the module "node-serialport" and use it with node-webkit 0.5.0.

The procedure does work on my mac but since I also need to distribute the application on Windows i have to build it on windows too. My Windows XP virtual machine has Vistual Studio 2010 installed. The build works fine with no errors generating serialport.node but then node-webkit is unable to open serialbox.node to load the module.

Uncaught Error: The specified module could not be found.
C:\Documents and Settings\Administrator\Desktop\baseflight-configurator\win\baseflight-configurator\node_modules\serialport\build\Release\serialport.node

even if the file is there.

Building with standard node-gyp and loading it with standard node works fine so.. what to do ?

[rogerwang]

Thanks for reporting. Could you please upload your binary somewhere so I can try it from here?

[davibe]

which binary ? serialport.node ?

I think it would be better if you try this on a windows machine

npm install nw-gyp
npm install serialport

then rebuild it with nw-gyp by hand

cd node_modules/serialport
nw-gyp clean
nw-gyp configure --target=0.5.0
nw-gyp build

and then try to load it from any node-webkit application using node-webkit 0.5.0

require('serialport');

you will see import error in the inspector (the same errors you would see requiring it directly from a normal node shell)

This procedure works as expected on macosx.

sorry, closed by accident

On Windows7, it works well.

Please check whether serialport.node exists. And if there are any error when running nw-gyp

let's see, I am using windows XP + visual studio 2010 (there is also vs2008 installed)

As you can see the file exists. It is not loaded by the standard node which
could make sense because it's built for node-webkit (does it?) but even loading
it using node-webkit gives the following error

Uncaught Error: The specified module could not be found.

Sorry I have been verbose but it might be useful. What could I try ?

This is my built serialport.node
I can't attach it here so I give you the link https://dl.dropboxusercontent.com/u/968175/serialport.node

[owenc4a4]

I use your file, it still works. This is my code: https://s3.amazonaws.com/node-webkit/owen-cloud/app.zip

oh my..

I changed the name from nw.exe to myAppName.exe and if I do that it does not find the module anymore (even if the path where it says it's looking for is right). If i rename it back to nw.exe it works. Also it works if I copy the exe and have both myAppName.exe and nw.exe in the application folder.

So.. it's "solved". It's not a bug of nw-gyp it's just strange behaviour of nw. Sorry to have bothered you.

[rogerwang]

Yeah, it's this issue nwjs/nw.js#199 . It should be added to the document to remind the users.

Hi Roger.

I found another issue i am not sharing on github because it's very
specific. I have an nw-application that uses a flash plugin i wrote to send
webcam stream to a Wowza server. The plugin works fine but it seems to have
problems with focus when i click the left button mouse and go to
"Settings.." to set up flash player input source (webcam, microfphone). The
result is that the configuration dialog does not work at all i can't click
any where. It's like it does not receive clicks. However i can use the TAB
keyboard key to put focus on items and use enter to select them.

This 'focus problem' holy happens in node-webkit every other browser works
fine.

I tried to open youtube website from node-webkit to see if their flash
plugin had the same problems too. In this case the click events works but
not always. I can clearly see i have to click more than once to get items
to react.

I am using last version 0.5.1 on the most recent mascosx.

I am sending you a small zip with the application i'm talking about so you
can try it if you have time.

Thanks.

@davibe I met this problem too.

[fifsky]

我的天啊，我在这个问题上卡了几个月，今天终于解决了，原来是不能重命名nw.exe文件名称，可是为什么呢，有没有办法可以替换 v0.12.3
