Hi Jim, After receiving your note about the 'mcidas' account being locked out due to too many incorrect passwords being tried, I was able to logon to the DU AIX machine this morning. Upon noticing that the setup of .cshrc did not follow the recommendations listed in the Preparing the McIDAS Account section of the Unidata McIDAS-X Users Guide: http://www.unidata.ucar.edu/software/mcidas/current/users_guide/PreparingthemcidasAccount.html I made some small changes: <as 'mcidas'> cd ~mcidas mv .cshrc cshrc.old -- create a new .cshrc file with the contents recommended in the page listed above I then proceeded to try and build McIDAS from scratch: -- logoff and then log back on to force use of the newly created .cshrc file cd ~mcidas/mcidas2007/src make clobber make all I believe that I got significantly further this time, but still not to the end. Here is the error message seen at the end of ~mcidas/mcidas2007/src/makelog: rm -f mci.o cc -c -O -I. -I../netcdf/libsrc -I../hdf/hdf/src -I../hdf/mfhdf/libsrc -I../jpeg -I../libpng -I../zlib -I../tiff/libtiff -I../libgeotiff -I../jasper/src/libjasper/include -I../g2clib mci.c "mci.h", line 31.10: 1506-296 (S) #include file <X11/extensions/XShm.h> not found. "mci.h", line 108.3: 1506-046 (S) Syntax error. "mci.c", line 422.24: 1506-068 (W) Operation between types "char*" and "const char*" is not allowed. compile mci.c: FAILED I believe that the real problem is that the include file XShm.h does not exist on your machine. For contrast, it does on our AIX 5.1 box: /home/mcidas/mcidas2007/src% ls -alt /usr/include/X11/extensions/XShm.h -rw-r--r-- 1 bin bin 4512 Apr 05 2001 /usr/include/X11/extensions/XShm.h I interpret this to indicate that your machine does not have a full X development environment installed. As soon as the needed extensions are installed (the MIT shared memory extension), the build should continue at least until the next hiccup.
