Error: Symbol node_stringprep_module not found.

[natevw]

I followed the instructions for OS X:

brew install icu4c
ln -s /usr/local/Cellar/icu4c/51.1/include/unicode /usr/local/include
ln -s /usr/local/Cellar/icu4c/51.1/bin/icu-config /usr/local/bin/icu-config
npm install node-stringprep

But still I get the "Symbol node_stringprep_module not found" error as in issue #27. I have node v0.10.5.

(I also tried rebuilding node-stringprep after linking to icu4c/49.1.2 as I see there is some vague issue with recent versions?)

Hi,

I don't have access to OSX full time to test an install so won't be able to look into the issue. If you, or someone, is able to provide a pull request I will happily merge this in.

Sorry I can't be more helpful!

Cheers, Lloyd.

If you know offhand — what is the icu4c version expected to work and the reason? There is insinuation in the README that 50.1 isn't the version I want — should I be trying to get it working with older e.g. 49.1.2, or might a newer e.g. 51.1 work again as well?

[lloydwatkin]

I believe its only currently compatible with the 49.X versions and not anything more recent. I haven't looked at more recent versions of ICU yet. Currently triaging all node-xmpp related projects and will try and pick things up as soon as I can.

If you'd be willing to test against 51.1 I'd be most grateful, but I'd imagine they switched from 49->50->51 because of BC breaks.

In the mean time pull requests most welcome. Thanks :)

Any resolution on this one yet? Im also getting some similar errors on OSX latest with latest node 0.10.15 and with attempting to follow the above instructions for brew. I believe Im on icu4c/51.1

any ideas or thoughts?

I also downgraded to 49.1.2 using the instructions about tweaking brew if it doesn't work.. still did not resolve the issue:

dyld: lazy symbol binding failed: Symbol not found: _usprep_openByType_51
Referenced from: /node_modules/node-stringprep/build/Release/node_stringprep.node
Expected in: dynamic lookup

I'm not an OSX user so unable to help with this issue I'm afraid. If you are using this with node-xmpp be aware this is not a requirement. If any OSX developers are willing to submit a pull request I will happily merge in.

Well i use this with node-xmpp because if i dont install node-stringprep it wont connect... it seems that it sends an empty stanza to the server... and never connects...

[lloydwatkin]

I'd suggest adding some debug around https://github.com/astro/node-xmpp/blob/master/lib/xmpp/jid.js#L2 to see what is going on with your system. It should fail-over if node-stringprep isn't available to you.

[kuryaki]

Yup followed your advice dunno why this happends but i have two versions of node-xmpp the one that doesnt work have this line

if (this.socket.readable){

in node-xmpp/lib/xmpp/connection.js

the one that works have instead

if (opts && opts.socket) {

I will probably move this to node-xmpp and discuss it there..

[lloydwatkin]

Glad to hear you have this sorted

[alexeichemenda]

@kuryaki did you find a work-around ? I'm having same issue with string-prep, using xmpp-client. Thanks !

May I close this one?
