Instruct node-gyp to use specific version of g++ and gcc #838

easwaraa · 2015-12-10T11:41:28Z

Hello,

I am new to the world of installing Javascript modules and I am having the task of installing capnp JS libraries using g++ v4.8 in our RHEL6 environment.

As we only have v4.4.7 in /usr/bin/g++, we decided to use the g++ (v4.8.2) installed in /opt.

I downloaded the source from https://github.com/kentonv/node-capnp and added the below lines to binding.gyp but it doesn’t work.

'make_global_settings': [
    {  
      'CXX': ['/opt/rh/devtoolset-2/root/usr/bin/g++'],
      'CC': ['/opt/rh/devtoolset-2/root/usr/bin/gcc']
    }],

When I straced the process, found that node-gyp is looking for the g++ libraries only in below location.

/usr/lib/node_modules/npm/bin/node-gyp-bin
/u/easwaraa/node_modules/capnp/node_modules/.bin
/usr/bin

I tried searching around to see if I can update the path somewhere but couldn’t find it. FWIW, I tried updating my .pathrc too but it didn’t help.

When I run npm install, I get the below message.

 ~/tmp/capnproto/temp_js_RPC/node-capnp $ npm install

How can I update node-gyp to use the different version of g++?

Please let me know if something isn’t clear.

The text was updated successfully, but these errors were encountered:

env CC=/path/to/gcc CXX=/path/to/g++ npm install should normally do the trick. If you want to use make_global_settings, you may have to set CC.host, CXX.host, CC.target and CXX.target as well.

It looks like you're using devtoolset-2; it's been a while since I last worked with that but I remember you need to start a shell with scl enable for it to be active.

easwaraa · 2015-12-10T14:35:51Z

Thanks for the quick response.

Setting the variables worked but still the node-gyp rebuild is failing.

I tried that already but it still fails.

cc1plus: error: unrecognized command line option "-std=c++11"

That error suggests it's not actually using g++ 4.8. What does env V=1 node-gyp rebuild print?

Initially ‘env V=1 node-gyp rebuild’ was failing with the below error.

Little googling, pointed me to http://stackoverflow.com/questions/17706310/how-to-add-path-with-module-to-python

And I installed the gyp libraries from chromium and now ‘env V=1 node-gyp rebuild’ is giving the below error.

Where does that file name come from? Are you still using make_global_settings?

easwaraa · 2015-12-11T12:41:37Z

Ah,, sorry I was using it before. When I removed it, its giving a different error now.

Is it happening because of capnp C libraries?

Is it happening because of capnp C libraries?

I would say so.

easwaraa · 2015-12-11T18:10:54Z

Any pointers on how to fix this?

[Sorry for bothering you. I spent some time digging this today but couldn't fix it].

bnoordhuis · 2015-12-16T16:10:28Z

Sorry, no idea. I'd ping the author of the node bindings if I were you. I'll close the issue.

easwaraa · 2015-12-16T16:23:21Z

Thanks for all your help.

FTR, I was able to make npm install work for capnp by using the below command.

env CC=/opt/rh/devtoolset-2/root/usr/bin/gcc CXX=/opt/rh/devtoolset-2/root/usr/bin/g++ npm install capnp

I was under the impression that there will be a .js file which our users can use in their code... But not sure if I have got the right one...

~/node_modules/capnp $ ls
CONTRIBUTORS LICENSE README.md bin binding.gyp build build.js package.json src

Thanks for your help once again :).

bnoordhuis · 2015-12-16T16:36:06Z

Look for the "main" field in package.json, that's the module's entry point. You don't have to include that file explicitly though, require('capnp') should do it for you.

easwaraa · 2015-12-18T07:26:32Z

This is what I have in the "main" filed in package.json.

"main": "src/node-capnp/capnp.js",
"peerDependencies": {
"es6-promise": "1.x"
},

Let me try to write some test JS code by using this module and see if it works. Thanks :)
