OpenVRML in snow-leopard (from macports)

Question

Hey, I just Downloaded openvrml from macports (port install openvrml) Now I have a Sample program (pretty_print.cpp from openvrml at sourceforge) that begins like this:

# ifdef HAVE_CONFIG_H
#   include <config.h>
# endif

# include <openvrml/vrml97_grammar.h>
# include <openvrml/browser.h>
# include <fstream>
...

then in Xcode, I added the following path and check "recursive" for the Header search path and Lib Search Path:

/opt/local/var/macports/software

And all '***.h file not found' errors disappeared, but now I have the following two:

complex.h 943 '__pow_helper' is not a member of std
c++locale.h 71 'vsnprintf' is not a member of std

/Developer/SDKs/MacOSX10.6.sdk/usr/include/c++/4.2.1/complex: In function 'std::complex<_Tp> std::pow(const std::complex<_Tp>&, int)':
/Developer/SDKs/MacOSX10.6.sdk/usr/include/c++/4.2.1/complex:943: error: '__pow_helper' is not a member of 'std'

both errors come from system files. I wonder what is causing this errors... Can anyone advice me on how to use openvrml samples on Macs?

thanks in advance.

I've had a similar problem. I defined "recursive" flag for an '/opt/local/include' path. This pulled in some strange c++ headers from boost compatiblity includes.

In general, you do not want "recursive" flag on your include paths.

Try unchecking "recursive" from your paths.
