I have a weather forecast model I am developing. It is based on MPAS model. I am using a new aproach to compile the code, with fpm.

I have a problem with multiple includes. I use the command bellow, but the system can not see the second include (ezxml):

```bash
> /opt/bin/fpm build --compiler 'mpif90' --flag -I/opt/gnu/include --flag -I/home/lufla/MONAN/ATMOSPHERE/src/ezxml (base)
+ which mpiexec
/opt/gnu/bin/mpiexec

     | ^ ~~~~~~~~

```

All the files are available in directory. How I inform to fpm another include directory? Or, how include in command more than one directory (-I)?

There are a few other possibilities, but note --flag is for Fortran, --c-flag and --cxx-flag are for C and C++. If you quote them more than one option is allowed per --flag or --c-flag. So I think the simplest thing is you needed to use --c-flag not --flag.

Also note that if you have a directory at the top of your project called “include” it is automatically searched for include files.

If you still have a problem, if you include the --verbose option on the fpm(1) command it will show  
the commands being executed, which would be useful in the post if problems remain.

```bash
fpm build --usage
USAGE:
KEYWORD SHORT PRESENT VALUE
version v F [F]
verbose V F [F]
usage u T [T]
tests F [F]
show-model F [F]
profile F [" "]
no-prune F [F]
list F [F]
link-flag F [" "]
help h F [F]
flag F [" "]
directory C F [" "]
cxx-flag F [" "]
cxx-compiler F [" "]
compiler F ["gfortran"]
c-flag F [" "]
c-compiler F [" "]
archiver F [" "]

```

If the C code includes MPI directives as well, you might want “-c-compiler=mpicc” as well, depending on your programming environment.

Note the --usage flag can be put at the end of your statement with all the other switches and will show you all the values you would have set without --usage; instead of just the defaults as shown above. Sometimes that is useful to verify you are setting everything the way you expect.

Without seeing your file structure I am not positive where your included file(s) reside; so the output of “tree src” might be useful too if problems persist.
