[Insight-users] compile problem: vnl object files not linked in!

[Zachary Pincus]

Hello,

I'm trying to compile ITK on Mac OS X 10.3.2, with python wrapping  
support.

ITK compiles fail on me at the build step of linking the libitkvnl_inst  
library, because it cannot find a lot of the vnl symbols. (Example  
error output at end of message.)

Strangely, when I run nm to show the symbol tables of some of the vnl  
object files (e.g. vnl_math.o) produced by the build, these missing  
symbols are clearly in the files. (Well, not totally clearly, thanks  
the c++ name mangling, which I am not an expert in.)

So it looks like the linker isn't being given the path of all of these  
vnl object files when it is trying to link libitkvnl_inst.

The only non-standard thing I'm doing with the build is adding python  
wrapping, which requires building shared dynamic libraries.

Any suggestions on getting ITK to link properly would be most  
appreciated.

Thank you,
