Some progress here.

First, you evidently have the latest public version of -oaxaca-.

Second, -oaxaca- is telling you that you do not have a variable
-male-. Is that true? Nothing in the commands you show us mentions a
variable -male-. The syntax of -oaxaca- is not that it feeds on
models; a glance at the help shows this. It takes a varlist.

In any case, I can't see that a variable called -male- is something
that you would want to feed to -oaxaca- as outcome variable.

Whether -oaxaca- offers you the kind of analysis you want in some
other way I leave to others. I've never used it.
