Problem trying to build Cygwin X server from source

Problem trying to build Cygwin X server from source

[Mark Lillibridge]

    This is xserver-cygwin-1.14.3-1, the latest as of several weeks ago.

    The part that is failing (make done in
/usr/src/xorg-server-1.14.3-1/src/xserver-cygwin-1.14.3-1/hw/xwin/glx):

    Any suggestions?  The online documentation is seriously out of date,
predating the use of cygport.

I think this is error is due to the khronos-opengl-registry package being more
recent than the wglext.h provided by w32api-headers.

I think the easiest way to work around this is to update wglext.h from
http://www.opengl.org/registry/api/GL/wglext.h

Which documentation, specifically?

Hmmm.  Which occurrence should I replace?

    mdl [103]# find /usr -name wglext.h -print
    /usr/i686-w64-mingw32/sys-root/mingw/include/GL/wglext.h
    /usr/include/GL/wglext.h

    Makefile:oldincludedir = /usr/include
    
    mdl [119]# grep mingw/include *

I'm guessing from the above that it's this one:

    /usr/include/GL/wglext.h

    I replaced that one and the code in
/usr/src/xorg-server-1.14.3-1/src/xserver-cygwin-1.14.3-1/hw/xwin/glx
now compiles.  Unfortunately, code now fails elsewhere:

cd /usr/src/xorg-server-1.14.3-1/src/xserver-cygwin-1.14.3-1/hw/xwin
make

    Hmmm.  You didn't just update the documentation on me did you?  The
versions Google is giving me now are up-to-date.

Page 9 of http://x.cygwin.com/docs/cg/cygwin-x-cg.pdf says:

    Tip: Use setup -q -Ppackagename,packagename,etc. to quickly install
    the required packages.

Darn if I could make this work no matter what I tried.  Really, you
should just give the actual code here so people can cut-and-paste.
Ideally, you should also specify how to get the needed packages via the
setup GUI.

Yes, I guess that's first in the include search path.

Since w32api now provides a that header, we should probably stop providing it
in libGL-devel.

You will need to apply the attached change to /usr/include/Xpoll.h to fix
xserver compilation with w32api-headers >= 3.0.0-1, which adds a new WIN32
define somewhere, which breaks this test.

It's not really the function of that document to tell people how to install
packages on cygwin.

I don't really want to put the package list there twice and have to keep both
copies updated.

If you're doing the package installation manually, you just find them (perhaps
using the search function), and select them for installation.

Subject: [PATCH proto/x11proto] Fix WIN32 check

Even if WIN32 is defined (because we have included windows.h somewhere), we want
to use the UNIX-like select() interface on Cygwin

This seems to be needed to compile xorg-server with MinGW-w64 w32api-headers
3.0.0, which add a new WIN32 define somewhere.

    It's /usr/include/X11/Xpoll.h on my system.  That patch indeed makes
the compilation proceed further.  It's now stuck at:

    I found that tip useless as in I couldn't make any form of "setup -q
-Pfoo" install a package.  As for the GUI, I believe I just set:

      * X11, editors, shells, net: install
      * X11->xorg-server: source
      * devel: install  [need for cygport]
      * Python: install [for lxml for X server compiling]

This is *way* easier than trying to find the dozens of packages by name
and trying to figure out what to check to get them.

Sorry, my mistake.

This looks like [1], a mis-match in TLS-ness between XWin and libglapi.

If you are building using the .cygport file it should have ./configure'ed with
--disable-glx-tls?

    Ah!  I had indeed screwed up the configuration -- I was manually
building in src using autogen.sh rather than in build and thus had lost
the configuration set up by cygport.  When I blew everything away and
did the cygport stuff again,

    cd /usr/src/
    cygport xorg-server.cygport prep
    cd /usr/src/
    cygport xorg-server.cygport compile

things built fine.  Thank you for all your help!  (To be clear, this
didn't work before the 2 patches you had me make.)
