Hi John,
Let me explain the Makefile patch in this separate thread, as this is generic to all maps.
Let’s not use gb18030 as an example, instead, using utf8_and_win.
When any of the win-related map file changes, it suppose to automatically rebuild utf8_and_win.o.
WITHOUT this patch, after I touch a map file, it doesn’t rebuild the object file:
Hmm. Yeah, this really looks somewhat bogus as you say. I wonder
though if we shouldn't have the UCS_to_*.pl scripts generate a bunch of
"mapdeps.mk" files instead, or something like that, given that these
*.map files are themselves generated.
Also, I suspect you should do something about Meson, but I don't know
what that would look like.
Based on Tom’s response in the other thread [1], this is a problem with make, it’s worth fixing.
As suggested by Alvaro, I will study on the “mapdepds.mk” direction a little bit.
