I have a node webkit application that uses the mdns module for publishing a Bonjour service from a Mac (with Mavericks). When I run the server code with node server.js
everything works OK, but when running the node webkit application that uses the same server code I get this error:
"Uncaught Error: dlopen(/Users/me/myfolder/node_modules/mdns/build/Release/dns_sd_bindings.node, 1): no suitable image found. Did find:
/Users/me/myfolder/node_modules/mdns/build/Release/dns_sd_bindings.node: mach-o, but wrong architecture", source: /Users/me/myfolder/node_modules/mdns/lib/dns_sd.js (35)
Apparently when you install the mdns
module with npm
it's built for an x86 architecture and I need it for i386, because node-webkit is built for i386 (I found out about this by reading this thread: http://forums.macrumors.com/showthread.php?t=879780). You can verify it by running this in a terminal:
$ lipo -info /Applications/node-webkit.app/Contents/MacOS/node-webkit
Non-fat file: /Applications/node-webkit.app/Contents/MacOS/node-webkit is architecture: i386
I found this link suggesting a solution: https://github.com/rogerwang/node-webkit/issues/296 for another module (node proxy). The suggested instructions are:
I managed to build a 32-bit version of node-proxy as follows:
I installed nw-gyp
I ran nw-gyp configure --target=0.3.6
I edited the generated file nodeproxy.target.mk in the build directory by replacing -arch x86_64by -arch i386
I ran nw-gyp build
But as I'm not used to building node modules manually, while following the instructions it wasn't clear to me in which folder I should run those steps (I assumed it's in the module folder inside node_modules
:
a) when I install nw-gyp I don't get the nw-gyp command to use globally (I guess the -g option is missing in the instructions)
b) using instead gyp configure --target=0.3.6
gives me an error saying that there is no option target
c) I tried skipping the configure step (just to try) and the build command breaks with:
Could not automatically locate src directory. This isa temporary Chromium feature that will be removed. Use--depth as a workaround.
But when trying to use --depth (of course) it requires an argument, I couldn't find out what to put there.
So... how should I build the mdns module for using it with node webkit? (either the 0.8.6 version or the 0.10.0, I can adapt).
