Building RISC OS from an sgit clone

I thought I’d try to build RISC OS from git just using RISC OS.

sgit clone https://gitlab.riscosopen.org/Products/BCM2835.git GitClone
dir GitClone
sgit submodule init
sgit submodule update

Make a cup of tea. Make lunch. Watch an episode or two on TV.

Run SetPaths from the DDE
Run Prepare from the RiscOS.Apps directory

Reboot, just in case.

Run the Builder (without the Filer first “seeing” C++ etc.), everything up to Join ROM.

Swear a bit, then remove a line "RES_OBJ = " from Desktop.FilerAct.Makefile (https://riscosopen.org/tracker/tickets/514) because I’m too cheap to buy a newer version of the DDE.

Run the Builder, everything up to Join ROM.

Yay!

One thing, though, running sgit diff doesn’t show the file I changed, but it does show dozens of things like this:

- a/RiscOS/Sources/Apps/Draw
+ b/RiscOS/Sources/Apps/Draw
@ -1 +1 @
-Subproject commit 99383d2197f04b00eccdabda275d5b17ef50be63
+Subproject commit 99383d2197f04b00eccdabda275d5b17ef50be63-dirty

Any bright ideas?

Never mind. I needed to go further down in the source tree. Go into, say, RiscOS.Sources.Kernel.s, and it works fine.
