Hi folks - I forgot to mention - the following machine specific include files need to be retrieved through anonymous ftp to sdsc.edu : bin.h arg. tag.h sdscconfig.h im.h They are found in the files in /pub/sdsc/graphics/imtools/ These can be placed in the module directories, or /usr/include These header files are included in the same tar files as libim.a and libsdsc.a - both of which need to be installed in /usr/lib for this module to compile correctly. Have fun, terry --- Terry Myerson International AVS Center North Carolina Supercomputing Center avs@ncsc.org
