[CPMD-list] Lahey F90 Compiler

[Juerg Hutter]

Hi

can't help you directly with the Lahey compiler,
but the -Y option of the Absoft compiler is not
used by the cpp. It determines how the compiler
names subroutines internally (lower case, upper case,
appending underscore, etc). This is important
to match names with external libraries.

Most likely you should ignore this option for
your compiler or replace it with the appropriate
option of the Lahey compiler. This option has 
nothing to do with CPMD directly.
