Re: JRate build failure

[Morgan D. <md...@mo...>]

Hi John,

Thanks for your interest.  Unfortunately jRate is no longer actively
maintained.  I haven't tried it for a few years, but as it's based on GCC
3.x, I'm not surprised that there are problems building on modern setups.

That said, I'm surprised it failed *after* bootstrap, but your attachment
didn't come through, so I haven't any idea what might have gone wrong.

Best,
Morgan

JRate build failure

[John A B. <nwo...@gm...>]

I attempted to build JRate as described in INSTALL with a local copy of
gcc-3.3.3.

The build failed after the gcc bootstrap.  I have attached the output
containing the error

I am building on Ubuntu 14.04 LTS

Any ideas?

thanks

Hi Francesco,

The group of us that developed jRate have moved on, and it is no longer
actively maintained.

Re: Jrate Question (I think configuration is OK - make comand doesnt run)

[Morgan D. <md...@gm...>]

Matias,

Have you unpacked the GCC 3.3.3 sources in the top-level directory
under "gcc" ?  It looks as though it is having difficulty finding the
GCC sources (they are not packaged with jRate and should be untarred
manually).

Re: JRate: Installation problems

[Morgan D. <md...@gm...>]

Hi Matias,

Curious, it looks as though the configure script cannot find gcc or
g++!  These are installed in /usr/bin on your host, correct?  And they
are executable (i.e., they dynamically link, they are for the right
architecture...)?

Also, this is when you try to ..../configure jRate, not a configure
step after you type "make" ?

Morgan

JRate: Installation problems

Porting jRate to GCC 4.4.0

[CharlieLin <sl...@yo...>]

Hi there,

By comparing the GCC 4x to 3x, you can find there are dramatic changes to
the autoconf and automake process. So I cetainly believe that some patches
of jRate 3.7.0-3.3.3 cannot be applied to GCC 4.x. Or it is possible but
requiring deep undertanding of how gcc works. 

Is there any brief intro of how the jRate patches works. Especially how does
jRate integrate with the GCC compiling process.


Many thanks. =^D=^D

The library code should be pretty straight forward to understand. The real
tricky part is the are the changes that were made in to the GCJ library,
front-end and back-end. Understanding those requires a bit of understanding
of how GCC works in general.

What are you trying to do? Let me know and I'll see how I can provide you
some hints and guidance.

Ciao,

[Cai Y. <yc...@st...>]

Hi,

I'm a student of University of York, and I'm trying to update some
features of jRate to cater RTSJ 1.1.
Now, I'm having the jRate source code, and the paper 'The Design and
Performance of the jRate Real-Time Java Implementation'. However, it's
hard to unstand this project in short time. Do you have more specific
materials to helping me unstand this project?

Thank you.

Re: Segmentation fault on jRate

[Haseeb <ha...@cs...>]

Hi Morgan,

Using the -m32 flag at JRate configure time gives me an error nanosleep()
not found. 

# ./configure --prefix....  CFLAGS=-m32
checking for pthread_create in -lpthread... no
checking for library containing nanosleep... no
configure: error: can't find nanosleep()

Without specifying -m32, it finds the it finds the pthread_create in
libpthread and doesn't care if nanosleep is present or not. I suppose I am
missing a 32 bit library but I can see libpthread.so in both /lib and
/lib64. Thanks for your help.

Cheers

Haseeb

The example you are showing above does not necessarily shows  
allocation into immortal memory as the object you are creating will be  
allocated on the memory in which the calling thread is executing.

Now, if you refer to the run-time checks that are needed in order to  
ensure the referential integrity then that is a direct extension of  
the GCC front-end + GCC runtime for Java. I can't recall the exact  
name, but I believe it should be something like Jv_write_barrier(). In  
any case if you search this in the jRate patches you should easily  
find it.


HTH.

Question: How static objects are allocated in jrate

[Mohamed A. <mra...@gm...>]

Hi

I just need to know how and in which file(s) exactly does the jrate
allocates the static objects in immortal memory, i.e. how jrate
differentiate between allocating objects referenced by the static
variable and objects referenced by instance variables.

e.g.

class xx
{
static cls ref1;
cls ref2;
   public void sommethod()
{
ref1=new cls(...);//in immortal
ref2=new cls(...);//in current memory area context of the current thread
}

}


cheers

Re: Segmentation fault on jRate

[Morgan D. <md...@gm...>]

Hi Angelo and Abdul,

Right, we never did any work on 64-bit.  However, I think I've since
tried jRate on amd64 without serious difficulty (at least of this
sort).  Still, with the kind of hardware-specific tricks we play for
embedded ia32 and ppc, I'm not surprised if we'd have to reengineer a
few things for amd64.

If the need for multilib was detected when jRate was configured, you
have 32-bit jRate libraries.  You can then try compiling
HelloWorld.java with "jRate-gcj -m32 ..." and see if that solves the
segfault problem.  Otherwise, I can recommend recompiling all of jRate
binaries and libraries for 32-bit (with CFLAGS=-m32 at jRate configure
time) and seeing if that works.

jRate-0.7.2-3.3.3 is installed but it gives a segmentation error in all

Re: Problems buildingjRate on AMD 64

Hi Haseeb,

In what "wrong" format is that file?  If you run "file
..../libstdc++.so" what do you get?  Is it a 32-bit object?  Or a
libtool stub?

Problems buildingjRate on AMD 64

[Abdul H. M. <ha...@cs...>]

Hi,

I am building jRate-0.7.2-3.3.3 on ubuntu 64 bit running on AMD64. 
GCC-3.3.3 builds without any problem if build separately, but when I try 
to build it with jrate the linker gives an error.

The --diasable-multilib option doesn't seem to work when the jRate patch 
is applied to gcc. The configure command that I give is as following:

1. root@haseeb:/opt/jrate/jrate-0.3.7.2-3.3.3# 
CC="/opt/gcc-3.3.3/bin/gcc" ./configure --enable-languages=c,c++,java 
--prefix=/opt/jrate/gcc --disable-multilib --enable-threads=posix 
--build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu

2. make gives an error

/opt/jrate/jrate-0.3.7.2-3.3.3/gcc-build/x86_64-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so: 
could not read symbols: File in wrong format
collect2: ld returned 1 exit status

I will really appreciate any kind of help.

Cheers

Re: Processing group parameters

[Morgan D. <md...@gm...>]

Hi Haseeb,

Sadly, no.  It's been on the shortlist of things to implement, but as
you can see on sourceforge, it's been that way for some time..

Processing group parameters

[Abdul H. M. <ha...@cs...>]

Hi,

Have you guys implemented the processing groups parameters in jrate in 
any sub-version??? I just wanted to avoid going through all the 
subversions, any help will be really appreciated.

Thanks

Re: Development on Jrate

[Morgan D. <md...@gm...>]

Haseeb,

There is some work in there on the physical memory classes, but I
don't recall how complete, tested, and/or standards-compliant it is.
You'll probably want to check out the most recent Subversion rather
than one of the releases.

jRate development isn't currently ongoing because we have no grant to
work on it (nor grants for projects that depend on it, which have
motivated many improvements in the past) and we have moved on to other
projects.

Cheers
Morgan

Development on Jrate

[Abdul H. M. <ha...@cs...>]

Hi,

There hasnt been much of an activity on the jRate website. I was 
wondering if development has stopped or are there plans for a new 
version release of jRate. I will be working on the physical memoy model 
of RTSJ and thought if you guys had done some sort of work on it.

JRATE on QNX

[Alexander L. P. <pa...@un...>]

Hi,


I'm interested in using jrate in the QNX Neutrino RTOS.

After using the configure script with the options ncpu=1, cpu-clock=893 (a
very old machine) and pagesize=4096 the makefile was succesfully generated.

I downloaded the required sources, but when i run make during gcc
configuration i'm getting the following error:

configure: error *** unable to determine the endianness


Thanks

Alex
