Re: Make error when compiling xserver-cygwin-1.14.1-1

[Matt D.]

The error appears to be here:

/bin/sh ../../ylwrap winprefslex.l .c winprefslex.c

'winprefslex.c' is not created but ylwrap is not returning an error. 
This is unfamiliar territory for me but I'll see what I can do.

Off the top of your head, is there a way to slim this down to remove 
ylwrap? Maybe it will throw something helpful.

That doesn't look right.  I have:

/bin/sh ../../ylwrap winprefslex.l lex.yy.c winprefslex.c -- flex -i

$ ./ylwrap  --help
Usage: ylwrap [--help|--version] INPUT [OUTPUT DESIRED]... -- PROGRAM [ARGS]...

So, it looks like maybe something has gone wrong in the autofoolery as it
hasn't found the name of your lex successfully, but has still configured.

I think now might be an appropriate time to ask if you have all the
prerequisites listed in [1]?

It seemed I had everything but flex. I downloaded that and 
double-checked all of the dependencies. Everything compiles now but I'm 
getting a linking error.

I am using a CLEAN install of cygwin with the following packages:

setup -P 
cygwin,autoconf,automake,binutils,bison,bzip2,cygport,diffutils,fileutils,findutils,flex,gawk,gcc,git,libtool,make,patch,pkg-config,sed,tar,w32api,dri-drivers,libbz2_1,libfontenc1,libfreetype6,libgcc1,libGL1,libpixman1_0,libX11_6,libXau6,libXdmcp6,libXext6,xauth,xcursor-themes,xkbcomp,xkeyboard-config,zlib0,libdmx1,libXaw7,libXfixes3,libXi6,libXmu6,libXmuu1,libXrender1,libXt6,bigreqsproto,compositeproto,damageproto,dmxproto,fixesproto,font-util,fontsproto,glproto,inputproto,kbproto,libXfont-devel,randrproto,recordproto,renderproto,resourceproto,scrnsaverproto,windowswmproto,xcmiscproto,xextproto,xf86bigfontproto,xineramaproto,xorg-util-macros,xproto,xtrans,khronos-opengl-registry,libpixman1-devel,libx11-devel,libgl-devel,libxkbfile-devel,libxcb-image-devel,lib-icccm-devel,glapi-devel

Prepping, generating, and configuring:

cygport xorg-server.cygport prep
autogen.sh -V
configure

And on make I get the attached linker error. I've tried cleaning and 
redownloading twice now.

 > I think now might be an appropriate time to ask if you have all the

Yes, I do. On that note, the prerequisites are missing:

libpixman1-devel
libx11-devel
libgl-devel
libxkbfile-devel
libxcb-image-devel
lib-icccm-devel

(detected during configure)

and

glapi-devel

(detected at compile-time)

There is also no sanity check for flex, although it is listed as a 
prerequisite.

Ah.  I think that page is in need of an update.

It probably would be better if it told you to use 'cygport xorg-server.cygport
compile' to configure and build, as then the configuration would match the one
used to build packages, which is known to work.

The undefined references to `__glapi_tls_Dispatch' should be fixed by
configuring with --disable-glx-tls [1]

No idea about this.  You should probably be using gcc4, though.

These undefined references are a bit mysterious. These wgl*Wrapper functions
should by defined in the generated_wgl_wrappers.c generated file.

Thanks for the list. I'll update the documentation appropriately.

Ok.  I guess I need to add one then :-)

Ah, this is probably due to needing python to generate these files, despite
not having an autoconf check for that.  I've added one.

I've added libglapi-devel, libxcb-icccm-devel and libxcb-image-devel.

The others seem to be already on that page.

They may not be getting installed by the setup invocation you give, I think
package name is case sensitive, and setup doesn't diagnose attempts to install
non-existent packages.

We already have a AC_PROG_LEX check.

Unfortunately, even with this autoconf assumes that lex will not actually be
needed to build as lex generated files will be shipped in the tarball made by
'make dist', and no error is reported if it isn't found.

Also unfortunately, the xserver tarball included in the source package
violates this assumption as it is generated by cygport directly from a git
tag, not using 'make dist', so doesn't include these generated files.

I've made a change so that the configure script in the xserver tarball
included in the source package will now require lex and yacc to be found.
