WRT: winetest-latest is outdated

[Detlef Riekenberg]

Hi.

The latest Winetest-Binaries are outdated
( http://www.astro.gla.ac.uk/users/paulm/WRT/CrossBuilt/?N=D ).

Winetest (ELF) compiled again recently
( http://www.astro.gla.ac.uk/users/paulm/WRT/wrt.php ),
but the crossbuilds are still missing.

Is there anything that we can do for help?

This is done by issuing "make test", IIRC.

And that is done by issuing "make crosstest", which currently fails on my 
box using most recent RPMs provided by Hans Leidekker.

I started asking Hans about this in my previous letter. :)

I've created an updated set of RPMs that allow me to cross build all Wine
tests again. Find them here:

Yup.

I'm trying to migrate from the old computer (an old RH-7.3 box much like 
Frankenstein's monster) to a more manageable machine (running Debian etch).  
Cross-building isn't working on the new machine yet and is currently broken 
on the old one.

That's true: the two builds are independent.  The wine tests had a different 
problem, for which I've a work-around now.

Yes.  The autoconf-generated script seems to be getting confused when 
cross-compiling.

When cross-compiling, I do something similar to the following:
  1. get the source-code and move to directory wine-cross-source

2. In directory wine-cross-elf, do:
    ../wine-cross-source/configure && make depend && make tools

3. In directory wine-cross-pe, do:
   ../wine-cross-source/configure --host=i686-mingw32msvc \
         --with-wine-tools=../wine-cross-elf

After that, it does a "make depend" and a bunch of other stuff to get 
winetest.exe, the DLLs and other EXEs.

Step 3 is failing.  It looks as if the configure script becomes confused 
between cross-building and native environments, in particular with OpenGL 
libraries.  Although the code is cross-compiling, it seems to pick up the 
native GL libraries and header files.  Then, when the cross-compiler fails 
(to link some glx symbol, iirc), the configure script dies.

When it fails, the configure script gives a hint that the 
file /usr/X11R6/lib/libGL.a should be removed.  Doing this certainly fixes 
the cross-compilation and the ELF compilation still works as it links against 
the .so version.  However, removing the xlibmesa-gl-dev package isn't 
feasible as its need by many other -dev packages and would break OpenGL 
compilation.

This looks like a bug in configure.ac, as why should a native static library 
break cross-compilation.

Any clues?

Cheers,

Paul.

config.log is available from:
  http://www.astro.gla.ac.uk/users/paulm/config.log

The last few lines from running configure are:
...
checking for GL/gl.h... yes
checking for GL/glx.h... yes
checking for GL/glext.h... yes
checking for up-to-date OpenGL version... yes
checking for glXCreateContext in -lGL... no
configure: error: /usr/X11R6/lib/libGL.a is present on your system.
This prevents linking to OpenGL. Delete the file and restart configure.
