Hi,
I have been using OSG in my projects for some time now and have had great
experiences so far!
Now we are trying to harness the power of C++ 11 features (my linux buddies
have been doing so for a while and I've been using older boost counterparts).
I decided to make take the plunge and try to get the project using c++ 11 on
Mac OS X.
I just rebuilt OSG 3.1.5 from source using my updated boost libraries and other
dependencies. I made sure when building OSG that CMAKE_OSX_ARCHITECTURES was
set to 'x86_64'. After installing OSG I made a dummy project that was (a)
using OSG (and OsgDB) and (b) using libc++ / c11 with clang. My dummy file
basically has one line related to osg:
Code:
osg::Node *node = osgDB::readNodeFile(modelName);
The linking process of my simple file fails, however, with the following:
Undefined symbols for architecture x86_64:
"osgDB::readNodeFile(std::__1::basic_string<char,
std::__1::char_traits<char>, std::__1::allocator<char> > const&, osgDB::Options
const*)", referenced from:
osgDB::readNodeFile(std::__1::basic_string<char,
std::__1::char_traits<char>, std::__1::allocator<char> > const&) in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Now I know for sure that I built OSG with the architecture x86_64, so I don't
think that's the issue. What I'mm thinking is more likely the culprit is using
the c11 standards.
Has anyone out there built against OSG using the following compiler flags?
-std=c++11
-stdlib=libc++
If I'm trying to do this, should I HAVE to build OSG itself with these flags?
Any help would be appreciated, thanks!
Cheers,
Kellen
