Checking on Including Paths in Makefile

I have some projects set up like this:

AppDev
    extensions\
        tUnit.t
	
    goldskull\
        src\
            goldskull.t
        makefile.t3m

What I want is the tUnit.t to be included in the goldskull build. The makefile.t3m in goldskull looks like this:

-cs utf-8

-D LANGUAGE=en_us
-D MESSAGESTYLE=neu

-Fs src
-Fy obj
-Fo obj

-o goldskull.t3

-I "../extensions"

-lib system
-lib adv3/adv3

-source tUnit
-source goldskull

Key there is the -I switch, where I would expect it to go up one to the extensions directory. But upon compiling, I always get:

Looking here (http://www.tads.org/t3doc/doc/sysman/univpath.htm), “for .t3m files, paths are relative to the .t3m file’s location.” So I seem to be putting in the correct relative path.

Just to be sure, I tried the full path as well, which is this:

-I "/Users/jnyman/ifT3/AppDev/extensions"

That also does not work. I get the same error: tUnit.t is unable to be found.

Not sure what I’m doing wrong here.

The “-I” option is for adding directories to the #include search list. For source files, use "-Fs ".

“t3make -help” will list all available options.
