No, the problem is the order of the parameters, put your LDFLAGS at the end in the makefile: # rule to link the program $(PROG): $(OBJS) $(LD) $(OBJS) -o $(PROG) $(LDFLAGS) BTW those are not really "LDFLAGS" it's the flags and the libraries, the problem with unresolved symbols is caused by the order in which the libraries are searched. -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

Wrong, localhost:10.0 is the correct value, and it is the one ssh sets for a good reason: ssh itself is listening to the respective port on the remote side, and will tunnel all the X protocol, encrypted and compressed or not, to the client side, where it will connect to localhost:0.0 which is where your Cygwin X server is listening. -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

It is probably not easy to do what the OP asked, and I haven't even tried but I think it is possible. First you have to know what you really want: running X as service will not magically produce a login window if you try to connect from another machine, and setting up gnome-session/xsm/ksmserver is probably not easy. But that is not a good objective anyway, if you wanted something like that you use any Unix OS. But, for an already logged in user, I think it just works (meaning a running X server will allow to open X applications). I do something similar, not a service that starts on boot, but a background X server that is running without the usual xterm that you can't close (the next step would be to test cygrunsrv with, and w/o, the -i option). -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

This is wrong, if you used "ssh -X" then DISPLAY is already set (by ssh) and it has a different value, usually localhost:10.0 for the first connection. The idea is that ssh will tunnel the X connection through itself (thus localhost) and it uses a configurable display number (the 10.0). The reason it works from some computers and not from others is that even if the X server exists at myipaddress:0.0 it could be blocked by any firewall between computers; the ssh tunnel is the way to avoid being blocked.

I think in your old installation you had changed the startup or your user's .xinitrc; this last one is usually the one that opens the xterm. If you don't have a ~/.xinitrc then it is a global script opening the xterm, that should be /etc/X11/xinit/xinitrc. If that is the case you can copy that one to your .xinitrc and make changes there. For instance you can edit the last line (commented below) and instead start xterm with your favorite options: #exec xterm -e /usr/bin/bash -l exec xterm -sb -sl 1024 -rv -geometry 80x25+0+0 -name login or even better, something like: rxvt -rv -display localhost:0.0 -sl 1024 -e bash -li (those are simple examples, you can do much more with other parameters). > cat /tmp/XWin.log _XSERVTransmkdir: ERROR: euid != 0,directory > /tmp/.X11-unix will not be created.

Then you didn't understood what I meant. Using netstat is going to show clearly what program is causing the problem, how? by counting how many open connections a program has. Something like "netstat -nb | grep XWin | wc" could give you a count. But my first try would be just using netstat to see what program has the most opened connections. In fact I've used this test before, about 2 or 3 years back Cygwin's dll was the one leaving connections all over the place... every time a thread was created a UDP connection was made an leaked (clamd was the program that I was tracing). But this was corrected and doesn't happen anymore. BTW this didn't cause the problem you describe with MS security, it caused so many opened connections that after a day or two (this was a server) no other connection could be opened. > Just so that we get on the same page here, I am currently not using > ssh -X, I am using the following: > > $ cat ..xinitrc > xhost + > ssh [EMAIL PROTECTED] 'cd development/dialer; ./invoke.sh 172.23.1.197:0.0' > > ... to invoke the application.

Try to keep the facts clear, if you don't understand why using netstat can help, say so, if you don't see anything on netstat's output maybe you are right or maybe you don't know what to look for. The description from Microsoft doesn't say clearly if it is the number of open connections or the speed of opening connections. If it is the number then it's easy to see with netstat; if it is the number/time then the number will not be that great but then the problem is probably a loop in your script or somewhere, XWin only opens a couple of connections, with ssh -X it's only one connection. -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

My point was that you need to run netstat to make sure it is XWin... saying "seems" will not encourage anybody to look into this. FWIW I don't think XWin is going to come out as the problem, as I said I haven't seen that problem (and I use ssh -X all the time) and something as big as "TCP/IP has reached the security limit" would certainly come up in this list very often if XWin was the cause.

Of course any Xwindows application can display on Cygwin's X server, java applications are just that, except many have an ugly default setting on window size and position (they use size 0x0 for instance) but that seems to be corrected in newer applications. >> I've been reading about gcj and that might work but it looks like I'd >> have to recompile everything myself.

Yes, Eclipse is being compiled with gcj (version 4.1.x not available currently under Cygwin) but that has nothing to do with showing Eclipse running on Linux. >> Does cygwin have a javax program that runs GUI java programs under >> xwindows? > > Unfortunately, no.

Sort of a cross-compiler but instead of code the cross targets display manager... sounds doable with gcj, even the old versions. But AFAIK no body has done it, all the development of gcj for Windows has been done under MingW, which by the way also has its own X server, but even there the AWT and Swing stuff has been replaced with SwingWT. -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

XWin seems to get the user's home directory (perhaps only the user name) from the shell environment, so it can run the user's .xinitrc . An option that I have not tested is to change the global xinitrc and see if that works. Of course being the global one means that all users on that computer will get the same application, but if you are the only user of X then that's no problem.

In fact you can start all the X applications you want after starting X. Now for the network problem, that is really strange, I saw your other message and understand that you can't troubleshoot the network. I really was thinking of troubleshooting in the regular way, on a terminal window, but if only SC has problems then perhaps is a timeout or some option that can be set inside SC. -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

You probably can just run a Windows shortcut to XWin with all the parameters, and use .xinitrc or .xsession to start up SC. If you want XWin to stay after SC is closed then just change the "wait $scpid" with "sleep 1d" or something similar. >> Your original post says that you had a network problem, can you show >> the actual message? > > no connection with POP3-Server: pop.gmx.de:110 That error has nothing to do with XWindows.

If I close the > Xterm SC will be closed too. Correct, the way XWin is started using startxwin.bat does make the whole server execution depend on the xterm, so when the xterm is closed XWin terminates. That can be changed easily by using startx (instead of startxwin.bat) and creating a file in your home directory named .xsession like this: #!/bin/sh # # FILE: $HOME/.xsession # exec SylpheedClaws /usr/bin/sylpheed-claws & scpid=$! # Now wait for program to terminate wait $scpid exit 0 You can also do the same at the end of your .xinitrc (that's what I use); in that case you don't even need the wait, when SC terminates XWin terminates. The reason I use startx is because it doesn't open an xterm, but if you copied the global xinitrc (in /etc/X11/xinit/xinitrc) to your home .xinitrc it also has execute xterm at the end... you'll have to comment that one too. > What I try to get is one script where I can start a Xserver without > any bash "window" and SC. > > More to explain I am not able with my English.

In Windows, to run, all programs need to find their components (.exe and .dll) and the search is done by the Windows loader which uses the Windows PATH environment variable plus the current working directory. My guess is that you don't have Cygwin's bin directory in your Windows PATH, and for XWin programs you also need the XWin bin directory in there. My Windows PATH starts with "%CYGHOME%\bin;%CYGHOME%\usr\X11R6\bin;%SystemRoot%\system32;%SystemRoot%;..."

The sh you killed is the one running startx, which is a shell script. The error message "Couldn't open compiled keymap file" comes from xkbcomp.exe, but I'm confused here, in your first message the keyboard was recognized fine: > (--) Setting autorepeat to delay=500, rate=31 > (--) winConfigKeyboard - Layout: "0409" (0409) > (--) Using preset keyboard for "English (USA)" (409), type "4" then in your second message the error appears: > (EE) Couldn't open compiled keymap file /tmp/server-0.xkm > (EE) Couldn't load XKB keymap, falling back to pre-XKB keymap so it looks like you changed something or what you mean is that startx hung just after the keyboard messages and when you killed it the "(EE)" messages appear? I think this is more of a Xfree86 problem but I don't know how to get more information out of the startup. One thing that may be usefull is to see what process is really hung. It has to be a child of the shell (startx) and it may be xkbcomp or something else. -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

Actually is more complicated than that, uic sometimes runs perfectly, then fails like above (except that with a snapshot, previous to latest release, it deadlocked on a mutex). In fact if you look at the output above the failure, uic ran many times generating .h files and I've seen that it does generate a few .cpp files before it fails. Even more strange, I've seen it run on the same file that it failed before when I ran it by hand, but not always...

Answering my own question: no, it doesn't work. Just tested it, rebuilt Qt with original script, build failed as always (uic produced an invalid file, truncated but this time uic did not print the "mutex failed..." message so it gets even weirder). Scribus dies as before. At the same time I also tested another idea, all the SIGSEGV signals that you can see under gdb are caused by uninitialized variables passed as parameters, so I added -Wall to CFLAGS to see if something jumps up.

All those "mutex lock failure" point to the threads implementation. If you want to go from "what changed in Cygwin's dll" forward, it has to be something in threads. Going the other way, what I tried is using gdb trying to look at what breaks the program. The worst part is that under gdb they run fine many times, then break (with the debug library). Yet another approach could be to do the porting of the newer 3.x/4.x version. -- René Berber -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

Right forum for qt3, wrong forum for kde.
The distinction is that qt3 is an official Cygwin package while KDE is from the
Cygwin Ports project.
The ports project http://cygwinports.dotsrc.org/ has its own mail list at:
http://sourceforge.net/mail/?group_id=99645
but read below.

[snip]
The error after "Resource deadlock avoided" is probably meaningless. My
experience with Scribus is that the application silently ended, another (QT3's
uic) deadlocked.
The solution I found for Scribus was to recompile QT with debug enabled, the
package building failed but the library was produced. Using that QT library
results in Scribus working fine... but with uic is another story, a very strange
story: sometimes it works, sometimes it doesn't.
I haven't debug any further but with gdb it looks like it's a thread problem
(the problem seems to be in some inline C++ code that is difficult to work
with). So another solution could be to build QT with no thread support (if that
makes sense and works).
I'm interested in this, but don't have much time. If I can help just ask, I
could show the way I built the debug version of the QT library for instance, and
I could do some testing if needed.
Regards.

That's a very different problem.
After you login to the remote machine execute "echo $DISPLAY", it usually is
wrong or at least that is my experience when using "ssh -X [EMAIL PROTECTED]"
to a
Solaris server... I even put into the remote machine's .bashrc :
if [ $TERM = 'rxvt' ]; then
TERM=xterm; export TERM
fi
if [ $TERM = 'xterm' ]; then
DISPLAY=`who am i | cut -f2 -d'(' | cut -f1 -d')'`:0.0; export DISPLAY
fi
Test it before you use it; as I said this was for a Solaris server (which didn't
know what a rxvt term was), it may not work on other Unix version.

If nothing works you should look into the log produced by Xwin, it's in

No, the original problem was not a SIGSEGV, it was that the program just exited silently after showing the splash screen and doing some initalizations.

[snip] Running Scribus with the debug enabled cygqt-mt-3.dll the program works fine with no mutex failure message and using the latest Cygwin snapshot. As mentioned in my reply to Brian, under gdb there are many SIGSEGV signals received but continuing results in the same behaviour as above: no problem. So there seems to be no regression, there must be something different btw. the original build environment and my PC. I used the code (build script, patches and original code) downloaded using setup.exe.

Yes, I know. But as I said, I'm unable to run this under gdb; tried strace on scribus (when it was stuck) and there was no output at all. I installed the .dbg file along with the latest snapshot. >> I could not build qt3 with debug enabled because the build also fails >> with a >> mutex problem. Actually the library builds fine with debug info, it's the Designer and its plugins where the build fails... but I need gdb working, even tried 2 different versions of gdb and also Microsoft's WinDbg, all show the same problem "Program received signal SIGSEGV ... in pthread_key_create". I'll look into this tomorrow, I've used gdb under XWindows in HP-UX and Solaris but this is the first time under Cygwin/X, perhaps something is different.

With both cygwin1.dll, the message always appears the only difference is that with the snapshot the program just terminates.

I took a look at the 3.3.5 code using XEmacs egrep to see the difference btw. 3.3.4 patched (from Cygwin ports) and this one, there really is not much difference, some double buffering used, some new calls that look like bug corrections. Anyway I was unable to build 3.3.5, early it complains about not finding a qt_windows.h file, somehow even with the "-platform cygwin-g++" the configuration code doesn't set the right defines. > 4.0.1 (and the soon-to-be-released 4.1.0) are entirely different; these > will eventually become a qt4 package (parallel installable with our > qt3), but only after it stabilizes more.

No, just start the X server. But if you don't start the X server the application just ends printing that it couldn't find the display, so that is not the problem you describe. In /usr/share/doc/Cygwin/scribus-1.2.3.README there is a list of requirements, usually setup.exe just downloads the requirements if they are not already installed but perhaps you have some old version of some of those, better check manually (I mean using setup.exe or cygcheck to see what version you have installed).

The problem should be with whatever cygminires.dll depends on to resolve names or with changed firewall settings (can't query DNS server because port 53 is not open), it could also be in /etc/hosts for the case where localhost is not defined as 127.0.0.1.

Then I downloaded the latest snapshot, version 20051207, and scribus fails as before (no error messages, the one I used as subject is only a warning, nothing). I could not build qt3 with debug enabled because the build also fails with a mutex problem. The program uic runs many times in the build succesfully but once it gets stuck with a "Mutex init failure: Invalid argument". I'm unable to use gdb, every time I try gdb on scribus the program is killed at the beginning (before the splash screen appears) while setting a pthread. In the code (src/tools/qmutex_unix.cpp), as you have already said, the "Mutex ..." messages are only warnings so they were not related to my original problem, the program should run but it doesn't with a recent cygwin1.dll. But those messages and the uic hanging do point out that there are problems with pthreads as used by qt3.
