Xilinx Coregen, command not found java error

[Zach Stechly]

Hi all -

I'm running Xilinx ISE 10.1 on a 64-bit linux machine, and I'm getting
a weird error. Designs which do not use a coregen generated file
compile fine...however, when I try and use coregen, or even generate a
core from the coregen GUI, I get kicked out with the following error:

Generating IP...
-cp: command not found
ERROR: coreutil:424 - An Error occured while running Java. Please
exaime the console or coregen log file for a specific IP related error
WARNING:coreutil:266 - could not remove outfile

I'm not sure why it couldn't locate the 'cp' command, as it is located
in /bin/.

Has anyone come across this error before? I have seen similar threads
about the coregen not being able to locate a file, but normally these
files are user specific, not the 'cp' command.

How can I tell where coregen is looking at for these files?

Thanks

The -cp option to java gives the classpath.

(Note that in linux, a filename can start with -, such that -cp
is a legal (though confusing) command name.)

That doesn't really help you fix the problem, but does explain
why the cp command isn't helping.

One possibility is that an environment variable is expanded inline,
and contains a semicolon. That would end the command, such that
a following -cp would be expected to be a new command.

Might also be that the environment variable JAVA (or whatever) is not
set, or set to the empty string.

Hey guys,

I figured it out - we were using the 64-bit version of Xilinx 10.1,
but we only had the JRE installed for the 32-bit version. Core Gen
went looking in xilinx/ise10/ISE/java/lin64 for the JRE, but couldn't
find it.

Thanks for all your help

ISE comes with a JRE bundled? Looking under /opt/Xilinx/12.2/ISE_DS/
ISE/java6/lin64/jre, I see it there. Its a shame they can't create
decent Linux distribution bundles in RPM or DEB format, and avoid this
kind of duplication.

ISE seems to have installed its own 32 and 64 bit JREs automatically
on my machine. I don't recall being given the option to deselect this
in the install process.

The ISE design suite is monolithic. Maybe Xilinx will change that if

they crack the 10 GB mark for the whole package :-/ ...
