Mason: multiple code files in project

Users

Hello,

I tried setting up a project with multiple files: src/ElkTo.chpl src/species.chpl

The project file ElkTo.chpl compiles but not species.chpl. I also tied putting species.chpl in a subdirectory and calling mason like this: mason build -M src/records/species.chpl but that just resulted in a mason usage message suggesting that the -M flag is undefined.

I assume I'm doing something wrong. I appreciate any help offered.

Thanks,
Roger

As an addendum, I also tried compiling manually, like this:

chpl src/species.chpl src/ElkTo.chpl

but that does not work:
src/ElkTo.chpl:4: In function 'main':
src/ElkTo.chpl:5: error: 'Species' undeclared (first use this function)

How does one compile multiple chapel program units into an executable?
Thanks,
Roger

Hi Roger,
Sorry to hear you're having trouble compiling your Chapel program. Without knowing too much about the contents of the files I am just guessing it's a visibility issue. Are you including a use or import statement in your ElkTo.chpl file to bring in the Species module? Something like use Species; or import Species; should be included to tell the compiler to make symbols from one module visible in the other. See Modules — Chapel Documentation 1.32 for more details on using symbols from other modules.

OK. Looks like the problem with Mason was having a file in the src directory with a name not matching the module name it contains.

Thanks & best wishes,
Roger
