[openvrml-develop] How to build OpenVRML on VisualStudio 2005 and 2003

[Larry M. <lar...@gm...>]

Hi,

I am making an attempt to use OpenVRML to verify the structure of
VRMLs I receive from a 3rd party. The current version I downloaded
ships with .sln files for VisualStudio 8.0 (2005) . I  searched but
could not find any instructions on how to build it with Windows (i.e
if some configuration needs to be done etc. ) I have downloaded Boost
and FreeType but now an getting an error related to compiling
resources

Compiling resources...
.\openvrml.rc(10) : fatal error RC1015: cannot open include file 'afxres.h'.
Build log was saved at
"file://c:\openvrml-0.16.5\ide-projects\Windows\VisualC8_0\OpenVRML\openvrml\Debug\BuildLog.htm"
openvrml - 1 error(s), 0 warning(s)

I'll eventually have to compile this with VS 2003 as our current stack
is using that. Anybody have any experience with that ?

Any help in this regard will be really appreciated.

Thanks and regards,

Larry.

Are you using the Express version of Visual Studio? If so, you will need 
to download the Platform SDK from Microsoft.

Not for some time. If you turn back the clock in the CVS repository 
(8/1/05 should do), you'll find some project files for Visual C++ 7.1. 
I'm really not sure how useful they'd be as a starting point; you may be 
better off just creating new ones based on what you see in the 8.0 
project files.

Thanks Braden - I was able to get past that but now I get the
following when building openvrml

LINK : fatal error LNK1104: cannot open file
'libboost_thread-vc80-mt-gd-1_34.lib'

I could not find reference to this library in any of the project settings.

Unfortunately, if I have to build boost for this, it's time to give up
for me....it's going to be a maintenance nightmare and I dont want to
support this forever....

Thanks for your help.

Boost takes advantage of a feature specific to the Microsoft compiler 
that lets it indicate what library will need to be linked in via the 
headers.

You can get pre-built binaries of boost from boost-consulting.com.

now I get the following linker errors....

[snip]

Those are FreeType symbols. Check to make sure the FreeType lib you are 
linking against actually exists. FreeType makes new releases frequently 
and the library names are versioned; so the library built by the version 
of FreeType you downloaded might have a different name than the one 
referenced in the project file that comes with OpenVRML 0.16.5.

Also note that FreeType is only necessary for *rendering* text. If you 
are only interested in reading in a file to verify correctness, you 
probably don't care about that. If you don't define 
OPENVRML_ENABLE_RENDER_TEXT_NODE, you don't need FreeType. See README 
("Significant preprocessor symbols") for more information.

[Larry M. <lar...@gm...>]

Thanks again Braden. I was able to build openvrml and everything else
in the project. I really appreciate your help.

Couple more questions

1. If I run sdl_viewer.cpp with a valid url (example
http://www.3dtrue.com/vrml/wrl/vrmlelevator.wrl) I get the following
error

unreachable URI
no alternative URI could be resolved

2. If I give the url as "file:///C:\temp\001\001.wrl" (which exists) I
get the following error

invalid URI
no alternative URI could be resolved

3. As you mentioned as reply to my initial questions, to verify that a
VRML is constructed correctly, I need to load it into a scene. So if
the following code does not throw an exception, that implies my VRML
is contructed properly, correct?

try {
        using std::string;
        using std::vector;
        const string url = argv[1];

        sdl_viewer v(url);
        browser b;

        vector<string> uri(1, url);
        vector<string> parameter;
        b.load_url(uri, parameter);
	  openvrml::scene s(b);
		
	  s.load(*s.get_resource(uri).get());
		
		


    } catch (std::exception & ex) {
        cerr << ex.what() << endl;
        return EXIT_FAILURE;
    }

Thanks again for all your help,

Rohit.

Hm; could be a bug. I'll look into this.

This is working as designed; URIs don't have '\' in them. Try using '/'
instead.

That's not very efficient; you end up loading the file twice.
browser::load_url should be all you need. The problem, though, is that
browser::load_url does not block. If you use it and you want to confirm
it succeeded, you can add a browser_listener for the initialized event.

However, it's probably easier for you just to use browser::set_world
instead of browser::load_url. set_world blocks; and if it finishes
without throwing, you're good.

I'm an idiot. Of course that doesn't work. sdl-viewer only supports file
URLs.

Braden,

Thanks for all the help. I've also been able to build it with Visual
Studio .Net 2003.

As it turns out, there is a minor bug here. You should have seen a 
different, more informative error message. (Note line 203 of 
sdl_viewer.cpp; unfortunately this exception is getting swallowed 
without emitting that error message.)

I will fix this for 0.16.6.
