[openvrml-develop] 0.14.2 on MacOSX

[Reed H. <re...@ze...>]

Hi all, I am trying to get OpenVRML 0.14.2 to compile on Mac OSX  (With  
GCC 3.3 -- "August 2003" Apple dev tools) , and have run into some  
problems. If anyone has any ideas, that would be very helpful.

Well the first few are easy:

(1) Headers are installed in PREFIX/include/openvrml/openvrml instead  
of just PREFIX/include/openvrml: just need to change  
libopenvrml/openvrml/Makefile.am:

openvrml_includedir = $(pkgincludedir)

rather than

openvrml_includedir = $(pkgincludedir)/openvrml

since pkgincludedir is already set to "$(includedir)/openvrml"

(2) To get it compiling I made two changes to the source code:

in lookat/ViewerGlut.cpp and lookat/lookat.cpp, change this:

# if HAVE_APPLE_OPENGL_FRAMEWORK
#   include <OpenGL/glut.h>

to this:

# if HAVE_APPLE_OPENGL_FRAMEWORK
#   include <GLUT/glut.h>

And I added -lobjc to lookat's libs.  I used the following configure  
script options:  --with-apple-opengl-framework --without-x  
--disable-script-node-javascript --disable-text-node

(I haven't tried installing spidermonkey yet, and for some reason  
freetype2 in fink doesn't work with openvrml-- there is a mysterious  
undefined symbol from freetype that causes errors).




OK, here is the hard one:

When I tried to run lookat, however, and also when I tried to run my  
own program linked with openvrml, I got a bunch of dynamic linker  
errors:

dyld: lookat Undefined symbols:

___cxa_pure_virtual
___gxx_personality_v0
Trace/BPT trap



So I reconfigured with LIBS="-lobjc -lstdc++", but I still got the  
errors.

I am 99.9% certain that all of my libraries used by OpenVRML were built  
with GCC 3.3.


Here are the link make commands. I don't know what it means by "having  
a real file for library -lstdc++".    /usr/lib/libstdc++.a is a symlink  
to a real file.  Maybe it doesn't like that it's a symlink?
   Well, I saved the old symlink and copied the real file into /usr/lib.  
  Still got the same warning...

I have rebuilt other programs that use most of the same libraries that  
OpenVRML does (libdl, libpng, libjpeg, libz, etc) and they work fine.

The one thing I am not sure about that might be affecting this is the  
fact that libtool always adds "-dynamiclib -flat_namespace -undefined  
suppress" when building libraries on the Mac for obscure Darwin/Mach  
reasons, and maybe some other flag somewhere "conflicts" with the  
resulting output? I don't know.   Does openvrml use any unusual C or  
Link flags that I might not be familiar with?

Also, what is the function of the ".lax" files libtool is producing  
(they seem to actually be directories containing ".la" files)? I've  
never seen that before.
