_Xglobal_lock

1998-10-27 Thread Jettero Heller 

I just installed jdk-1.1.6.5-2libc5.i386.rpm.

Whenever I run javac (or any other link to the .java.wrapper), I get this:

ls: not: No such file or directory
/usr/local/jdk1.1.6/bin/i586/green_threads/java: can't resolve symbol '_Xglobal_lock'
/usr/local/jdk1.1.6/bin/i586/green_threads/java: can't resolve symbol 
'_XUnlockMutex_fn'
/usr/local/jdk1.1.6/bin/i586/green_threads/java: can't resolve symbol '_XLockMutex_fn'


What is it?

Re: _Xglobal_lock

1998-10-27 Thread peter . pilgrim 

 Where are your X Window Libraries?
 
 Everyone has them set a /usr/X11R6/lib
 
 Set the library LD_LIBRARY_PATH=/usr/X11R6/lib:
 or set up `ldconfig' by editing your `/etc/ld.so.config'
 file.
 
 
 What distribution do you have Slackware or Red Hat ?
 
 If RH5.0 use the glibc version ie libc 6.0 and above.
 
 If have an older Slackware stick with libc 5.0 you may have to 
 recompile the XFree86 3.2.2 sources to include  multithreaded support. 
 That means downloading first the `LinuxThreads' library, compiling and 
 installing in `/usr/lib' as `/usr/lib/libpthread.a' . Setting up the 
 Imakefile config `site.def' or `linux.cf' files to use -D_REENTRANT 
 -lpthread etc. I cant remember exactly what I did to get JDK1.1.6 to 
 work properly.

I favour GNOME, as I have been using it's beta software for 4/5 months,
and it's already improved the way I work. SEUL looks very immature in
comparison. GNOME's being developed by many full-time/part-time and
volunteer developers (inc me), and is sponsored by RedHat. It also works
on non-Linux Unices. 

_Everybody_ wants to make Linux (/Unix) a viable desktop alternative to
Windows, for very obvious reasons (e.g. Windows sucks). If everyone
starts their own project to provide a user-friendly front-end to do
this, so much effort is wasted and/or duplicated. If everyone
collaborated on one project, it would reach fruition much faster, and we
would see the demise of Windows much quicker.

However, GUIs for Linux isn't the subject of this list, unless someone
is planning on writing one in Java, in which case I'd ask 'Why?'

Re: Image scaling

1998-10-27 Thread Uncle George 

i suppose this has something with the prob that i was having with drawImage of
demo/molecule viewer.  At initialization time, a shared seg is created between the
client & X server to communicate the images u wanna draw - BUT it is a fixed size,
which is based upon ur first image. Guessing, from my experience, when the images
grow larger, more space is needed, but just not reallocated between client & X
server. Client says new size, server says No Way this image can fit in this shared
space. X refuses to paint, and java ignores the error. User see's a blank screen :(

So this is my guess for this night.

You could write a Java front-end to a CORBA exported filesystem.

bug fixed ..

1998-10-27 Thread Manolis Perakakis 

Hi !

I 've been using on Linux versions 1.1.3 & 1.1.6v2 (libc version)
Recently i've downloaded 1.1.6 v5 (also libc version NOT glibc)

with that last version i get the following when trying to run java:

/UNIX/speech3i/home1/users/perak/jdk116_v5/bin/../bin/checkVersions:
{isGreaterOrEqual: command not found
/UNIX/speech3i/home1/users/perak/jdk116_v5/bin/../bin/i486/green_threads/java:
can't load library 'libXp.so.6'

: I don't want to 've any printing capabilities in java , so is there
any way to bypass the problem
& run java without libXp ?( maybe installing by source or changing some
script?)

(I 've got Slackware 3.1 -'96' with 2.0.29 kernel , libc.4.7.6 & 5.4.23
& libdl 1.8.10 )

Also, i had some problems using Buffered stream over a gziped stream via
sockets & some problems with sound(i 've allready reported that here)

Could you tell me about the fixes in 1.1.6 v5 regarding sound & buffered
io?

Also , the bugs you fix are bugs of the compiler , the JVM or both?
(So as , to know if i should recompile from a previous version having
that bug)

Thanks a lot !!
Perhaps if i get more free time in future i would be interested to join
the poring team..
(I currently work on a program for deploying speech recognition on WEB ,
so i use java & Native 
methods , as SUN doesn't support recording !!)

appletviewer complaining about LD_LIBRARY_PATH

1998-10-27 Thread Ian Clarke 


Hi, I am using JDK1.1.6v5 on a RedHat 5.1 system.  The java interpreter
seems to work (although I haven't tried it out with any programs which use
the AWT) however when I launch Appletviewer it complains about no library
path being set.  If I set the LD_LIBRARY_PATH to /lib then this error
disappears but it complains about something else.  I don't know much about
library paths but a friend told me that I shouldn't need to set the
LD_LIBRARY_PATH to anything for appletviewer to work.  It is possible that
this is an Appletviewer specific problem, or it may be a general problem
with anything which attempts to use the AWT.

I don't have further details to hand right now but I could provide them if
nescessary.

Any ideas anyone?

Ian.

I've read something about this somewhere in the Swing docs or source :).
The FileDialog uses more information than the java.io.File class
provides. I believe the JDK 1.2 File class will be extended to address
these problems.

Kevin Hendricks (mailto:[EMAIL PROTECTED]) tells me they've fixed
my bug in the 1.1.7 source; the description he gave sounds much like
yours. 

Incidentally, for the rest of the list - response on that was
phenomenal. Kevin had checked my example code and responded within 30
minutes of my filing the bug report in Jitterbug, and there was a
solution in less than two days. Kudos galore; if Kevin or any other

A bug in appletviewer

1998-10-27 Thread John Summerfield 

Extrace the attached java applet into a new directory, say ~/javabug. Call
the file "bug.java."

Compile it as you'd compile any java applet, maybe
javac bug.java

Run the applet thus:
appletviewer bug.java

Click your various mouse buttons on the frame window and take not of its
behaviour.
 Change directory and run it again: maybe
cd ..
appletviewer javabug/bug.java

Note that this time there's a warning message in the top of the window
warning the user that this is an applet window. You will also note that
some of the text the applet attempts to display is obscured by this
message.

This behaviour is different from that I observe with 
   Appletviewer on NT 4.0 Sp1 JDK 1.1.4
   Netscape 4.something on NT
   Netscape 4.06 on Linux
   Appletviewer on OS/2 JDK 1.1.4
   Netscape 2.02 with Java 1.1.4 on OS/2
and in pictures in my book Just Java, Sun Microsystems.

In all these cases, the warning message is at the bottom of the window: in
principle the user can, if something seems obscured, resize the window to see
what's hidden.

I have
[summer@possum public_html]$ java -version
java version "1.1.6"


I don't seem to have the downloaded file to tell me more precisely.
However, the timestamp on java is "Aug 29 19:07."

When working with frames you have to honor the frame's insets.
The insets include the frames border size, the title bar size,
the menu bar size, the warning bar size.
So it's no bug, your code is not 100% portable ;-)

Have you tried to use something like:

Insets insets = getInsets();
int top = insets.top;
int left = insets.left;
super.paint(g);
g.drawString(s,5 + left ,40 + top);
g.drawString(s2,5 + left ,80 + top);
g.drawString(s3,5 + left ,120 + top);

it seems to be working fine but its very slow it seems when running Window

Hi,

I am pretty new to java and linux.  I need your help on the following
problem.
after extracting "jdk_1_1_6-v5-libc5-x86_tar.gz" to one directory, I
run "java".

I got the error message like the following:

...Checkversions: {isGreaterOrEqual: command not found
..bin/i586/green_threads/java: can't load library 'libXp.so.6'.

The Linux version is Redhat 4.2. Kernel is 2.0.30

How to fix this problem quickly? I mean I can do it without upgrading
the
whole OS.

You can find with emacs's i-serch "{isGreater" easily.

mshen> ..bin/i586/green_threads/java: can't load library 'libXp.so.6'.

This message tells you to use X11R6.4.  But you can solve this problem
with installing only libXp.so.6 into your linux box.

mshen> The Linux version is Redhat 4.2. Kernel is 2.0.30

I'm sorry, I don't know RedHat Linux.  As for me, for example, I'm a
Slackware user, getting a x332bin.tgz from slackware site(
www.cdrom.com ).  And I installed only libXp.so.6.2 like following.

# tar xvzf x332.tgz -C /tmp
# cp /tmp/usr/X11/lib/libXp.so.6.2 /usr/X11/lib
# cd /usr/X11/lib
# ln -sf libXp.so.6.2 libXp.so.6
