basic file creation / dataset issues about hdf5.node HOT 7 CLOSED

Ok, I tested an hdf5-test user -like project on Ubuntu just now. Heading to work to try this on mac.

Are permissions different on mac? to folder such as /tmp?

from hdf5.node.

i also tried the local repo path to no avail. the file definitely gets created for both tmp and repo path and fails with the same error.

thanks for the quick response, i'll have a go on ubuntu later on as well.

ok, I repeated the test on a mac 10.7 node v0.12 gcc-4.9 and couldn't repeat the error with what it pulls from git. Didn't open the h5 with hdfview but it's size is 2184 bytes as it is on ubuntu.

I wonder if the group even got made. Maybe check if the group.id is 0 or greater.

You r way of setting up a dependent project? For this test I made a node_modules sub folder and put a sym link to hdf5.node in it.

You may have done similar because the hdf5.node/index.js appears to be working and hdf5/lib/globals.js is being found

from hdf5.node.

my current test script:

#!/bin/bash

function pause(){
   read -n 1 -p "Press any key to continue..."
}

export HDF5_HOME=/home/roger/NodeProjects/hdf5
export NODE_HOME=/home/roger/Software/node-v0.12.0/dist
export PATH=/home/roger/Software/gcc/dist/bin:$NODE_HOME/bin:$PATH
export LD_LIBRARY_PATH=/home/roger/Software/gcc/dist/lib64:/home/roger/NetBeansProjects/zlib/lib:$HDF5_HOME/lib:$LD_LIBRARY_PATH

#export HDF5_PLUGIN_PATH=/home/roger/NodeProjects/HDF5Plugin

node ./index.js #2> /dev/null

node --version
node -e "console.log(process.versions.v8)"

pause

and index.js

var hdf5 = require('hdf5').hdf5;
var h5lt = require('hdf5').h5lt;

var Access = require('hdf5/lib/globals').Access;

var file = new hdf5.File('/tmp/foo.h5', Access.ACC_TRUNC);

var group=file.createGroup('pmc');
var buffer=new Float64Array(5);
buffer[0]=1.0;
buffer[1]=2.0;
buffer[2]=3.0;
buffer[3]=4.0;
buffer[4]=5.0;
h5lt.makeDataset(group.id, 'Refractive Index', buffer);
var readBuffer=h5lt.readDataset(group.id, 'Refractive Index');

from hdf5.node.

on mac DYLD_LIBRARY_PATH instead of LD_LIBRARY_PATH

from hdf5.node.

ah i see, i think it really might just be a problem with the env vars (library path especially). i'll give it a shot tonight and report back. thanks a ton for the help!

took me a while to check it out, sorry, but good news. it works and it was the incomplete environment vars. i'll now be happily digging deeper into this subject. thanks for all the help and especially for this module in the first place.
