To test if the model compiles on your machine, select a suitable makefile in
the src/Makefiles directory and copy it into the src directory under
the name makefile. Then go into the source directory src and execute
``make''. If things fail you will have to adjust the makefile to your system.
The different makefiles in src/Makefiles provide you with some guidance
on how to change it on different systems. We successfully compiled QTCM on Compaq
Alpha OFS1, Cray J90, IBM AIX, PC Linux (Intel ifc and Lahey-Fujitsu compiler),
Sun Sparc and SGI Irix machines for which we provide example makefiles in the
src/Makefiles directory. If you run into problems please let us know.
Due to the various preprocessor macros in the code the compile process has to include a
preprocessor step. Have a look at your Fortran-90 documentation to see how to activate it.
N.B.: Unfortunately, some Fortran-90 insist on specific file name
extensions to correctly compile Fortran-90 code with preprocessor directives.
One group of compilers prefers an ``.F90'' extension to include a preprocessor step
while others refuse to compile anything with such an extension. We chose the
``.f90'' extension which works on most systems. Sometimes one has to specify a
compiler specific flag to enable the Fortran-90 preprocessor (see FPPON in
the makefiles). The exceptions are the Lahey-Fujitsu (PC-Linux) and the IBM-AIX
compilers for which the file name extension hasto be changed. The makefiles for
these compilers do this automatically the first time the model is compiled.
