Command didn't produce json file #5

Open zakimohzani opened 8 years ago

zakimohzani commented 8 years ago

Hello, Great job, mister. Unfortunately, the following line doesn't work in my R2013b.

json.write({'a',NaN,'c'},'test.json')

Could you explain why?

kyamagu commented 8 years ago

Did you compile the java code first?

kyamagu commented 8 years ago

It could be that Java version is not compatible with the provided jar files in java directory. If that's the case, you have to compile java package using the provided Makefile.

zakimohzani commented 8 years ago

Not sure what compiling does. How do I compile java code in matlab? I've tried the command with {'a','b'} and it works. I'm using the json provided from your website 0.2.2. Am 23.03.2016 11:39 Vorm. schrieb "Kota Yamaguchi" <notifications@github.com

Ok, then download the latest version from Github. v0.2.2 does not support inf/nan values.

zakimohzani commented 8 years ago

Sorry to bother you, here's another roadblock for me. Am I add supposed to add the org folder to the path?

>> json.test.run
=== json.test.dump ===
Undefined variable "org" or class "org.json.JSONObject.NULL".

Error in json.dump>dumpData (line 80)
    obj = org.json.JSONObject.NULL;

Error in json.dump (line 67)
  obj = dumpData(value, options);

Error in json.test.dump (line 29)
    str = json.dump(fixtures{i,1});

Error in json.test.run (line 11)
    tests{i}();
zakimohzani commented 8 years ago

Alright, so then I tried to compile it by running your Makefile but also failed, I guess it can't find the other files. I'm using cygwin now to make it.

Hmm, looks very much like a Java version issue. What does ver command say about Java VM version? I'll investigate.

zakimohzani commented 8 years ago

Alright, so I took the binaries from Maven and used their jar and now it runs.

Alright, probably the Maven version doesn't support Inf/nan values but other conversions will work.

zakimohzani commented 8 years ago

You're right, it doesn't. So what should I do now? Wait for you? Am 23.03.2016 3:27 Nachm. schrieb "Kota Yamaguchi" <notifications@github.com

kyamagu commented 8 years ago

I'll investigate, but meanwhile you can try to compile java codes by changing the classpath in javac.

kyamagu commented 8 years ago

@zakimohzani If you haven't fixed this issue, checkout the latest commit. The minimum requirement for Java is now ver 1.6.0_65.

zakimohzani commented 8 years ago

Sorry Yamaguchi-san for the late reply and I do appreciate your efforts. Further apologies for the fact that I can only test it later as I will be flying out for work soon. Do remind me once in awhile as I am very forgetful. (Too many issue trackers to follow, I need an aggregator for the issue trackers :P)
