[Insight-users] ImageJ and ITK on Solaris

[Michael Bell]

Insight Developers,

In Wrapping/CSwig/SwigRuntime/JavaCWD.cxx, the load function applies
flags to linux when running dlopen. These flags also need to be
applied to Solaris (all unix perhaps?):
#if defined(__linux__) //apply to solaris also
  	 # include <dlfcn.h>
  	
  	 int JavaCWD::Load(const char* lib)
  	 {
  	   return dlopen(lib, RTLD_GLOBAL|RTLD_NOW)? 1:0;
  	 }
 #else
  	 int JavaCWD::Load(const char* lib)
  	 {
  	   return 0;
  	 }
  #endif

I have made this change in my local copy and tested it successfully in
my application. I don't know what the global ramifications would be.

What would it take to have ITK tested nightly on a solaris machine? I
would like to help pursue that if possible.

thanks,
michael
