Problem building JNode

Submitted by d3atiq on Mon, 12/07/2009 - 16:54.

Hi,

I am new to JNode. Smiling With that said, I am trying to build the 0.2.8 sources in Windows XP and I am getting an error in the JNasm.java and JNasmPP.java native2ascii conversion. I don't get what is happening but it is related to 2 comments in these files, around the author name (Levente Sántha). When I open the files in an editor such as jEdit it shows correctly (i.e. I see an a acute), but in the next ant target I get the following:

prepare:

javacc:

native2ascii:

compile:

the compiler error output for details.

I have checked my default file.encoding and it shows as Cp1252. Why is it trying to use US-ASCII for anything and why do I get the error?

Thanks in advance,
Douglas

You should get a more recent version.

That error has been fixed many months ago.

For example, the character in fault has been replaced by \u00e.
We are using US-ASCII + java notation for unicode characters (like the \u00e mentionned above) for all JNode source code to avoid such problems.

Thanks for your response.

Now I noticed that 0.2.8 it was released almost a year ago. I'll try the trunk head. But that seems to be the latest release announced...

By the way, I would love to read a somewhat detailed explanation of the build process. Something like a tutorial on building JNode by hand would provide great insight to those involved in using or developing it. I know it is probably obvious for those that are used to the code, but I am just arriving and I would like to a bit more than "run build.bat" to get started.

Cheers,
Douglas

Hi,

This is just to let you know I succeeded in building JNode from the trunk HEAD (rev. 5690 to be exact). I was also able to run it on VirtualBox. Will play around a bit.

I have also imported sources into Eclipse. Where should I go afterwards for a source code overview/getting started/first steps?

Cheers,
Douglas
