Cygwin/Windows XP Build Instructions & Chromium Client Error

[GoogleCodeExporter]

What steps will reproduce the problem?

From http://code.google.com/p/quake2-gwt-port/wiki/BuildingAndRunning
1. Prerequisites:
a. Install Chromium, not Chrome (tested with 5.0.394.0 (46121))
  You may find a shortcut with --no-sandbox --enable-webgl useful
b. Install Cygwin (1.7.5-1 + packages @ 20100501)
c. Install vorbis-tools in Cygwin setup.exe (tools 1.2.0-2 lib 1.2.3-1) 
d. Install Java SDK in Windows (Sun jdk 1.6.0_20)
  Set JAVA_HOME to C:\Program Files\Java\jdk<version>
  Add/Set to CLASSPATH C:\Program Files\Java\jdk<version>\lib;C:\Program 
Files\Java\jdk<version>\jre\lib
  Add to PATH C:\Program Files\Java\jdk<version>\bin;C:\Program 
Files\Java\jdk<version>\jre\bin
  (Tested with Windows System Environment Variables, which are 
automatically propagated to newly opened Cygwin shells)
e. Build lame in Cygwin manually (3.98.4 to /usr/local by default):
  ./configure
  make
  make install

2. Check Out Latest (@ 20100501)
a. Follow Instructions
b. Apply Attached Patches using patch:
  Unpak directory separator patch
    - for Windows Java only - already works for Unix/Cygwin Java
    - change to use Java's directory separator rather than hardcode '/'
    - other locations hardcode '/' but this has not been an issue yet - see 
attached list (some of these may be URL paths and OK)
  WAVConverter deadlock patch
    - avoids deadlocks in child processes due to unread stdout/stderr
    - optional debugging output

3. Build using shell script (not batch script)

4. Install Resources using shell script (not batch script)
  If you see errors about a missing png file, the first patch isn't working
  If you freeze on a large wav file, the second patch isn't working

5. Run Dedicated Server using shell script (not batch script)
  If you see errors about a demo level not found, the unpacking was 
incomplete

6. Navigate to Local Address in Chromium
  You may need to disable popup blocking for localhost

  If you see HTTP ERROR: 500 war\GwtQuake.html (The system cannot find the 
file specified):
    you've deleted the web files from war (oops!). You can start again from 
step 2, or just replace the 7 files and 1 subdirectory from 
http://code.google.com/p/quake2-gwt-port/source/browse/#hg/war

  If you see other errors about missing files:
    some files may not have unpacked correctly
    you may not have run cp -r maven-
build/server/target/gwtquake/war/gwtquake war

What is the expected output? What do you see instead?

Expected:

Quake 2 Game

Actual:

Web Page:

WebGL Support Required

Please provide any additional information below.

Server appears to run fine. Log attached.
Will try reinstalling 20100501 build of Chromium and report results.

I was unable to install the latest build today. I think it's my machine.

Tested using Chromium 5.0.395.0 (46213): --no-sandbox --web-gl

Same Error:

Browser:

WebGL Support Required

For a list of compatible browsers and installation instructions, please refer to

http://code.google.com/p/quake2-gwt-port/wiki/CompatibleBrowsers

http://localhost:8080/gwtquake/3F5EB2DF5D73681377881A2A6FBDBB9C.cache.html

Also, WebGL demos from http://www.khronos.org/webgl/wiki/Demo_Repository
fail with 'No WebGL context found' - WebGL + CSS gets halfway.

In Firefox 3.6.3 on my machine:

Quake fails with exactly the same error, but nothing on the console.

WebGL + CSS works, and some others appear to get further.

It may be my graphics card - Intel(R) 82865G Graphics Controller.
http://blog.vlad1.com/2009/09/21/webgl-samples/ suggests I may need software 
rendering.
Is there any way to enable it for Chromium?

I posted this comment in
http://code.google.com/p/quake2-gwt-port/wiki/CompatibleBrowsers.  I'll go 
ahead and
file an issue on this.  Thanks a bunch for the great write-up on getting this 
to run
on Windows!

After CL 45293 (http://src.chromium.org/viewvc/chrome?view=rev&revision=45293),
Chromium returns a new string for GL_VERSION (OpenGL ES 2.0 Chromium). This is
correct as WebGL is based off of OpenGL ES 2.0. Previously, Chromium was just
returning the version string returned by the underlying OpenGL driver, which is 
not
correct. The Quake2 app is expecting a pure version number, and tries to parse 
it as
a float, and this throws a NumberFormatException?? when it tries to convert 
"Ope" :) 

This project needs to be updated to parse the OpenGL ES version string 
correctly, not
an OpenGL version string :)

Figured as much from my resource, unfortunately I understand javascript,php,c++ 
and c
but not java. If anyone has a patch, Ill test it.

Can the title be changed to reflect the 'java.lang.NumberFormatException: For 
input 
string: "Ope"' part?

This is true for Ubuntu Chromium nightlys as well, currently "6.0.406.0 (47376) 
Ubuntu"

@robbies: What file is the error in? Thanks for finding it.

@thebigguy: sure, let's split the bug, as long as the Windows build 
instructions go
somewhere useful.

I've posted them at the end of
http://code.google.com/p/quake2-gwt-port/wiki/BuildingAndRunning but they'll 
probably
get lost in the comments.

Can someone with wiki access update the wiki with the Windows instructions?
(And the challenge to get it building without Cygwin!)

Maybe that's not the best idea as
http://code.google.com/p/quake2-gwt-port/issues/detail?id=24 already correctly
reports the "Ope" bug.

I hope this may help. The file where the error is occurring is in 
src/jake2/render/glconfig_t.java

I don't really have a thorough understanding of GWT, so I am not sure where 
this file 
necessarily came from. I am more than familiar enough with Java though to 
realize 
that the naming convention of that file is a little off, so I am not sure if 
the file 
is autogenerated or what.

The fix I came up with was to change line 39 from:
version = Float.parseFloat(version_string.substring(0,3));
to:
version = version_string.replace("[^0-9\\.]+", "");

But this still gives me a black screen as the code just fails later with a 
black 
screen after loading all the webgl context... I might need to log this as a 
separate 
error:

...GL_ARB_multitexture not found
BF1F7D9E093C03DADB9923410B9F7384.cache.html:7098Missing multi-texturing for

So I hope that fix may help others because it did at least get me past the 
first 
error

Hi, 

thanks for the windows instructions!

The chromium issue should be resolved now, please retry. 

Will close this issue when I have copied the Windows instructions to the Wiki.

I just built last night using the instructions above and the server starts 
without any error. When navigating to the page in Chromium I still get the same 
"WebGL Support Required" error page. The javascript console reports this: 
"Failed to load resource gwtquake/B924BEE1D47DEDEB0CDF9C5090FD34A7.cache.html"

Do other WebGL examples work for you in Chromium, e.g. any of 
http://www.khronos.org/webgl/wiki/Demo_Repository

• Changed state: Accepted

[GoogleCodeExporter]

The windows issues should be fixed with the patch from issue 34.
