Did you check carefully that the module shown by nm and the undefined module are identical, especially in terms of caps and also the number of leading and trailing underscores. That is what most often does things in.-Roy M.

After some initial headaches netcdf seems to have installed itself correctly. The problem occurs when I try to use the netcdf.mod file in a simple test fortran program. I call the netcdf function nf90_open and when the code compiles /usr/bin/ld raises an undefined symbol error. The symbol it cannot find is named __netcdf_MOD_nf90_open. I have discovered that when xlf compiles modules it prepends the two underscores, the name of the module and _MOD_ to all function calls. I used nm to look into libnetcdf.a and the function is in there. This leaves me wondering what the problem is. Does anyone have any insight? Please let me know if you need more information, I have been battling this problem for a number of days and I am coming to my wits end. Thank you for any assistance or attention you may pay to this problem. Best regards, Ryan Glover
