Are Native modules supported. about node-packer HOT 15 CLOSED

I was planning to scan and statically link all native modules during compile time (theoretically it is feasible since we are building from the source and could make some change to how native modules are loaded), but failed to find time to do it. I'll implement it as soon as possible. Thanks for the feedback!

Node.js Compiler v1.0.0 released! Native C++ modules are fully supported now.

https://github.com/pmq20/node-compiler/releases/tag/v1.0.0

@mauron85 Could you have a try and let me know if it works for you? Thanks!

from node-packer.

I dont know node-compiler but did you nodec run with --npm-package=node-time-uuid ?
Maybe you need compile native before you can use it?

from node-packer.

@mauron85 Native modules are starting to work on the master branch, if you are urgent you could clone the repo and run nodec from master to try it. I'll release it once I have tested it thoroughly.

Hey @pmq20,

I just tried this out on an application I'm working on. It says it built but throws:

return process.dlopen(module, path._makeLong(filename));
                 ^
Error: dlopen(/__enclose_io_memfs__/node_modules/bcrypt/lib/binding/bcrypt_lib.node, 1): image not found

Seems like bcrypt wasn't built/included into the build? Is this an error or potentially something I did wrong? I have Node 8 installed on my Macbook and am using V1.0.0.

from node-packer.

To note I also get a number of ../deps/libsquash/sample/enclose_io_common.h:38:28: warning: variadic macros are a C99 feature [-Wvariadic-macros] in the build process. ex:

../deps/libsquash/sample/enclose_io_common.h:40:29: warning: variadic macros are a C99 feature [-Wvariadic-macros]

../deps/libsquash/sample/enclose_io_common.h:49:22: warning: variadic macros are a C99 feature [-Wvariadic-macros]

Could this be related?

I tried this as well with sqlite3 with issues as well:

My index.js I'm trying to compile:

console.log(process.version)

var knex = require('knex')({
  dialect: 'sqlite3',
  connection: {
    filename: './data.db'
  }
});

// Create a table
knex.schema.createTableIfNotExists('users', function(table) {
  table.increments('id');
  table.string('user_name');
})

// ...and another
.createTableIfNotExists('accounts', function(table) {
  table.increments('id');
  table.string('account_name');
  table.integer('user_id').unsigned().references('users.id');
})

// Then query the table...
.then(function() {
  return knex.insert({user_name: 'Tim'}).into('users');
})

// ...and using the insert id, insert into the other table.
.then(function(rows) {
  return knex.table('accounts').insert({account_name: 'knex', user_id: rows[0]});
})

// Query both of the rows.
.then(function() {
  return knex('users')
    .join('accounts', 'users.id', 'accounts.user_id')
    .select('users.user_name as user', 'accounts.account_name as account');
})

// .map over the results
.map(function(row) {
  console.log(row);
})

// Finally, add a .catch handler for the promise chain
.catch(function(e) {
  console.error(e);
})
.finally(() => {
  return knex.destroy();
});

I'm using nvm with node8.

Compiling normal packages works nicely.

@firrae I failed to reproduce this on my local machine. See the screenshot. Could you check your build log to see if some error occurs when building bcrypt?

from node-packer.

@ptusch Do you have more message regarding this particular failure:

deps/libsquash/enclose_io_libsquash.target.mk:97: recipe for target '/tmp/nodec/node/out/Release/obj.target/enclose_io_libsquash/deps/libsquash/sample/enclose_io_memfs.o' failed

The error message is too much truncated for a diagnosis.

Ping @ptusch

Also, have you cleaned your temporary directory that the compiler uses? If old directory generated by nodec 0.x is used then it would be problematic. It needs to be cleaned when a compiler of a new version is used. I should fix this in a precautionary way: #42

from node-packer.

@pmq20 Please forgive me, I think I forgot to add sqlite3 to the package.json.
I just reinstalled and everything went as expected.

Well done btw!

from node-packer.

@pmq20 where would the cache be? I had used nodec before the latest version so that may be it. I'm digging around to see if I can find it on my own. I am on a Mac.

from node-packer.

@pmq20 nevermind, I see it's a command line option. Rebuild seems to have worked well. Now I just need to figure out the sequence of flags needed to include our public folder and it looks like it'll work. This is awesome. Thanks!

from node-packer.

Looks like I just need to sit our Public folder beside the executable and it works :D

Closing this as native modules support has been added in v1.0.0.
Feel free to re-open it should you need it
