[Insight-developers] Problem again in NRRDIO

[Gordon L. Kindlmann]

Hello,

Shoot- sorry about this; I was just thinking the NrrdIO update was  
finished!

There indeed probably aren't any tests for checking compiling  
applications against both Teem (containing the air, biff, and nrrd  
libraries that these symbols are coming from) and ITK (containing  
NrrdIO, the fraction of Teem required for Nrrd file IO).  Aren't  
Slicer builds doing this?  Are there analogous tests for, say,  
compiling applications against non-ITK zlib and ITK name-mangled zlib,  
which can be copied from?

I can tell that these names are for the global variables that exist in  
NrrdIO.  These are probably not getting correctly picked up from the  
list of symbols in the NrrdIO library, which mangle.pl does by using  
"nm".

Michel, can go through the NrrdIO process on whatever platform you  
used last, and at the point of running mangle.pl, can you run "nm"  
manually and grep for, say, _nrrdStateGrayscaleImage3D, and see how  
that symbol is identified?  Line 66 of mangle.pl apparently is missing  
this.
