Hm.  What do you have your /bin/sh pointing to?  Try changing the
first line of the configure script to use /bin/bash instead, and see
what happens.  I've tried running under ash and dash without trouble,
and the parts you have indicated are in the autotools-generated part
of the configure script and should be portable across shells.

Hallo,
I am new in linux and i got problem installing JRate. I followed the instruction given in the install.txt. I create the build folder, put gcc folder in it and then ../configure. After that i want to run "make" and here comes the eror. My gcc folder content gcc versiom 3.3.4.

Here is the error messege:

[root@localhost build]# make
make  all-recursive
make[1]: Entering directory `/root/rtzen/jrate/build'
Making all in .
make[2]: Entering directory `/root/rtzen/jrate/build'
make[2]: *** [gcc.source-stamp] Error 1
make[2]: Leaving directory `/root/rtzen/jrate/build'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/rtzen/jrate/build'
make: *** [all] Error 2

 
I am using linux RedHat9, gcc 3.2 installed by default.

Best regards,
Leo

The CVS version of jRate comes without a configure script.  You must
have GNU autotools installed (autoconf, automake, libtool).  Please
read the README.cvs file in the top level for version requirements.

I haven't seen this before.  I'll have to look at it.

Still planned, but stalled because I've been working on other
projects.  Cost overrun support is already implemented.  However, I
need to audit and probably overhaul the entire waitForNextPeriod()
mechanism to bring it into compliance with the specification, and I
need to add support for cost overrun/miss handler triggering to the
async event code.  (I think current status of CVS is that cost overrun
support is there for periodic threads, but not for AE handlers.)

It's preferable to run jRate-compiled applications on a kernel that
fits your application.  For an application without strict RT
requirements, the stock kernel may perform fine.  For applications
with stricter requirements, you'll want to look at various real-time
flavors of kernel.  There's a discussion of kernel options in the
archives:

You're welcome, good luck.

Hi,

In order to test advance features like cost enforcement, 
processingGroupParameters or AsyncEventHandler behaviours, I've tried to 
install the CVS version of jRate.
But after having checkout the module jrate, I did not find the 
"configure" executable ... why ?

Then I decided to install the beta 0.3.8 available on the sourceforge 
web site, but I got an error during the configure process :

/./configure:  line 24795: syntax error near unexpected token '('
./configure:  line 24795: 'echo "on '(hostname || uname -n) 2>/dev/null 
| sed 1`" >&5'/

Can you provide me some help ?

Then I will take advantage of this email to ask you if a release 
0.4.0-3.3.3 is still planed ?
will the costoverrun and miss handler be implemented ?

Eventually, is it preferable to run jRate on a rtlinux free kernel or on 
one of the last release of official 2.6 kernel, or on the last debian 
patched 2.6 kernel ?

Thank you very much.

      Hi everyone,
  
  Has anyone tried to use the ClassLoader defineClass method in jRate to load
  classes at run-time. For my part, I've tried to use it and I get the following
  errors.
  
  Exception in thread "main" java.lang.InternalError: Unexpected exception while defining class MyClass
    at java.lang.ClassLoader.defineClass(java.lang.String, byte[], int, int, java.security.ProtectionDomain) (/opt/jrate/lib/libgcj.so.4.0.0)

  I've ran the same code with a normal jvm (gcj and sun's java) and it works.
  
  Any Ideas?
  
  Thanks,
  Jean-Paul Etienne
