Using CMAKE and gfortran to compile DSSAT in Windows about dssat-csm-os

Here are the contents of the CmakeCache.txt file in case it helps:

# This is the CMakeCache file.
# For build in directory: d:/My Downloads/dssatclone/build
# It was generated by CMake: C:/Program Files/CMake/bin/cmake.exe
# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
# If you do want to change a value, simply edit, save, and exit the editor.
# The syntax for the file is as follows:

# KEY is the name of a variable in the cache.
# TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!.

CMake will only build the project (i.e., load all source and set dependencies) for your compiler. Now you have to use your compiler and linker to build the executable.

[helsharif]

Thank you for your reply, so I was able to begin the compiler by navigating to the directory containing the Makefile in Windows command prompt and running the command:

mingw32-make

The compilation process began, but the following fatal error occured:

`[ 77%] Building Fortran object CMakeFiles/dscsm047.dir/Plant/SAMUCA-Sugarcane/SC_rm_file.f90.obj
f951.exe: Warning: '-fd-lines-as-comments' has no effect in free form

mingw32-make[1]: *** [CMakeFiles/dscsm047.dir/all] Error 2
Makefile:147: recipe for target 'all' failed
mingw32-make: *** [all] Error 2`

It took some digging, but I found that I had to go to the source file:

SC_rm_file.f90

and change lines 18 and 50 which currently have:

inquire(file=io, exist=file_exists)

to

inquire(unit=io, exist=file_exists)

as the "file" tag can only accept character input, but the unit tag can accept integer input, and io is declared to be an integer.

After making that change the compilation successfully completed and I was able to produce the dssat executable.

[chporter]

OK, thanks! We try to keep our code as portable as possible. We will make this change to the code base. Thanks for letting us know. I'm glad you got it compiled.
