[Openmd-developers] QHULL as static while building

[Martin Vala]

Hi Dan,

what about this?

#if qh_QHpointer  /* see user.h */
   if (qh_qh){
       printf ("QH6238: Qhull link error.  The global variable qh_qh was 
not initialized\n\
               to NULL by global.c.  Please compile this program with 
-Dqh_QHpointer_dllimport\n\
               as well as -Dqh_QHpointer, or use libqhullstatic, or use 
a different tool chain.\n\n");
       exit -1;
   }
#endif

Ciao
