X11 apps failing after upgrade


All help gratefully received!  I haven't found this problem through
searches, apologies if I've been searching for the wrong terms.

In my first update in a few months I picked up the major upgrade to the
X server.  XWin -version now reports 1.5.3.0.  After having the problems
below I did a full reinstall of Cygwin, with no success.

My symptoms look similar to tunneling via `ssh -X`, but it happens with
both `ssh -Y`, and when I do `xhost +` and display directly to
<server>:0 without ssh tunneling.  

My client machine is Solaris.  Everything worked fine before the update.
I'm running the installed startxwin.bat startup (with xterm REM'd out).

I can display xclock fine.  xterm appears up, but as soon as I hit a key
it crashes with:

>>>>
  $ xterm
xterm:  warning, error event received:
X Error of failed request:  BadAlloc (insufficient resources for
operation)
  Major opcode of failed request:  136 (XKEYBOARD)
  Minor opcode of failed request:  16 (XkbSetNamedIndicator)
  Serial number of failed request:  117

Installed CygwinX and xhost not found

Hi,

I have just installed CygwinX on my new laptop which is running MS XP Pro version 2002 service pack 2. I used
install options All User and Unix mode. I also took the default of downloading all packages. I am trying to
setup a X window environment so I can run the Oracle Universal Installer to load Oracle onto my zOS
mainframe environment.

The first time I started Cygwin from the desktop short cut, I issue the command xhost + , I then received the
error message 'bash: xhost not found'. So I have searched the FAQs and found a note that says to add a path
statement to correct this problem. Next, I remembered the installation said I could customize the
C:\cygwin\home\rraso\.bash_profile by adding this statement 

PATH="/usr/local/bin:/usr/bin:/bin:$PATH".So I customized the profile and retried the shortcut,
followed by xhost +, same resulting error message. After removing the change, I tried inserting the path
statement into the Cygwin.BAT file, both before the change directory command and after the bash logon
command. Both tests produced the same results 'xhost + not found'.

Next, I reinstalled the software but I installed the CygwinX support. I checked the CygwinX documentation
and in chapter 4, it talks about starting CygwinX with either startwxin.bat, or startxwin.sh or startx. I
have searched my Cygwin files for this members and do not find them. I was expecting to find one or more of
them. 

Do I create a startxwin file? If not, did my installation not work correctly? 

So at this point, I am not sure where to insert the path statement or even if I have the right statement to
insert into someplace the Cygwin files.

Any suggestion will be greatly appreciated.

Recent X11 upgrade and getting _gl?? Undefined references compiling another package

I periodically do test compile for OpenSceneGraph in Cygwin and up 
until I recently accidentally updated to the latest X11 stuff the 
compiles had been working fine.  With the recent change I now getting a 
lot of undefined references for various _gl?? References.  I posted 
this to the OpenSceneGraph list and they suggested I also post here.  

The package uses ccmake/cmake and from the settings in ccmake when I 
review them it seems to be properly finding OpenGl according to cmake 
as:

 OPENGL_INCLUDE_DIR               /usr/include
 OPENGL_gl_LIBRARY                /usr/lib/w32api/libopengl32.a
 OPENGL_glu_LIBRARY               /usr/lib/w32api/libglu32.a 

the following is the errors and I have include the output from cygcheck 
-a -r -v.  Is this related to the upgrade or something else - any and 
all suggestion or answers greatly appreciated.

RE: Installed CygwinX and xhost not found

Lots of apps have moved into their own packages.  xhost can be found in
the X11 group, to be installed on its own.  However, it's generally a
good option to connect to your client with "ssh -Y" and then you can
display directly, without using xhost. 

I have a Cygwin-X menu item, with "XWin server" option in it.  I think
that's a default install...  It runs /usr/bin/startxwin.bat (which was
created/installed automatically).  If you don't have that it must have
been one of the X11 items I selected - not sure which.

HTH,

James.

for missing xhost, the correct FAQ is 
http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-where-is-xxyzy

If it's the Cygwin/X FAQ which has given you the wrong advice to adjust your 
path, can you please give me a reference so I can correct it

See point 15.

For the startup scripts you need to install the xinit package.

Sorry.  I managed to confuse myself somehow.

I suspect you might have the problem discussed here:

WMaker compile

Hello,

let first start by introducing myself: I'm a long time linux user, and tired
of rebooting the home machine because childrens can't play Zoo Tycon under
linux. I've just fiddled a bit with WindowMaker, and finally compiled the
latest version, 0.92. It ran out of the box, configured as

CC=gcc-4 CPP=cpp-4 CXX=g++-4 ../configure --prefix=/usr --sysconfdir=/etc --libexecdir=/usr/sbin
--localstatedir=/var --datadir=/usr/share --mandir=/usr/share/man --infodir=/usr/share/info --with-gnustepdir=/usr/lib/GNUstep/System

Two explanations:
1) the path reflect the way there are setup in the corresponding debian package
2) I compiled it under gcc-4

In order to make it run:
1) create a ~/.xserverrc file with
export CYGWIN=server
exec X :0

This ensures the X server starts with the MIT-SHM ewtension enabled, run 
'cygserver-config' once to have the required service enabled under Windows

2) launch wmaker at the end of .xinitrc as
exec env CYGWIN=server LANG=fr_BE.UTF-8 wmaker 

This ensures that wmaker can access shared memory from the client side
So ... it works. I used it with Belgian french locales. 

I would like to share the new wmaker package. To this
end I tried to install it locally as

This appears to be an issue with connecting to the Cygwin/X server from X 
clients from older X versions running on Solaris

See the thread at [1]

This thread references [2] (and it can also be found at [3]), which would 
suggest this is not a cygwin specific issue, but seems to be something that 
has changed in the X.Org 1.5.x server.

Those bugs reference some Solaris patches, which, as far as I can tell, 
upgrade X to a later version.  Applying those is the only solution I know of 
at this time.

I did some searching, but I can't find a X server patch for this issue.  If
