Champs,

I have a package with two modules, ModA and ModB. In ModB.c I include ModA.h. In the application config script, only ModB is included with xdc.useModule(). Should ModB.xs:module$use() include ModA with xdc.useModule() to ensure that ModA's module$meta$init() and module$use() functions are called? Or does this happen automatically?

Thank you
~ Ramsey

as a rule, whenever ModB #include's ModA.h, there should be a
corresponding xdc.useModule for ModA in ModB.xs. without "using" ModB
in this manner, the module$use() function of ModB will *not* be called.
failure to "use" modules at config time that are "used" in your target
code can often result in linker errors.

as for module$meta$init(), this function is called when the package
containing the corresponding module is loaded -- independent of whether
the module is "used" or not.... the purpose of module$meta$init is to
essentially "finish" some initialization of config params that could not
be handled statically in the .xdc file. for example, the default value
of Task.stackSize might be a function of the current target/platform --
known only at config time.
