To inform everyone, I finally was able to get osgEphemeris to work in my
application. To do so, I had to make a few changes to the source. All
the changes had to do with std::strings. I'm not exactly sure why I
needed to make these changes, but they solved the problem. Here they
are:
1. In EphemerisModel.cpp, I had to replace this line:
_ephemerisData = new (EphemerisData::getDefaultShmemFileName())
EphemerisData;
with this line:
_ephemerisData = new ("/tmp/EphemerisData.shm") EphemerisData;
2. In StarField.cpp, I had to comment out the definitions of
StarField::_vertexShaderProgram and StarField::_fragmentShaderProgram.
Then I had to put the actual string values in the calls to
program->addShader().
3. In MoonModel.cpp, I had to comment out the definitions of
MoonModel::_vertexShaderProgram and MoonModel::_fragmentShaderProgram.
Then I had to put the actual string values in the calls to
program->addShader().
If anyone knows what could have caused these problems, I'd love to know.
Thanks to everyone who offered advice!

After looking at the call stack during the crash, the problem seems to
be occurring here:
OSG Viewer.exe!`dynamic initializer for
'osgEphemeris::EphemerisData::_defaultShmemFileName''() Line 16 + 0x27
bytes C++
That references the following line in EphemerisData.cpp:
const std::string osgEphemeris::EphemerisData::_defaultShmemFileName =
"/tmp/EphemerisData.shm";
I tried changing the path in that line to c:\\EphemerisData.shm since I
am using Windows, but I still got the same error. Has anyone seen this
before?
Thanks,
Andrew

Mike, Gordon,
I was finally able to fix the linking error. I'm not exactly sure what
caused it. Both of my projects were built with /MD. Today, I deleted
my entire osgEphemeris directory and synched back to CVS. Then I
rebuilt the libraries and tried linking. It worked. I definitely tried
this yesterday with no luck. I must've been making a stupid mistake
somewhere.
Unfortunately, I now get a runtime error. I can link fine and even use
#include <osgEphemeris/EphemerisModel>. But when I insert code to
create the instance of the EphemerisModel
(osg::ref_ptr<osgEphemeris::EphemerisModel> ephemerisModel = new
osgEphemeris::EphemerisModel), I the runtime error occurs.
Specifically, the program's crashing at
_ASSERTE(_CrtIsValidHeapPointer(pUserData)) in dbgheap.c. This happens
before my program even loads. In fact, I don't even get near the line
of code that is supposed to create the EphemerisModel instance. Once
again, I'm stuck. I appreciate your help.
Andrew

Looking at the error messages it look like it could be a Runtime library
missmatch
Make sure all your projects are built with Multi-threaded Debug DLL
(/MDd)
or Multi-threaded DLL (/MD)

Mike,
I synched to CVS yesterday, so I definitely have the most recent build.
I'm using VS 2005. I can build and run EphemerisViewer.exe with no
problems. I tried modeling my vcproj settings against those of
EphemerisViewer, but I still get linking errors. I'm completely stuck
here.
Thanks for your help.

Also,
are you able to build EphemerisViewer.exe without error?
Perhaps model your build settings after vc7/Viewer/Viewer.vcproj
instead?
