STM32CubeIDE not doing incremental builds

[Lars Beiderbecke]

When I change a simple .c file and build the project, STM32CubeIDE always compiles all the files, including the unchanged ones. And there is no dependency between that one .c file and everything else.

Again, I didn't experience this behavior with TrueSTUDIO.

Which settings should I check to enable incremental builds with STM32CubeIDE?

[TDK]

There's not really a setting that controls this. Builds are makefile based and "make all" will do an incremental build when possible. That is the default behavior.

This is Eclipse behavior, not anything STM32CubeIDE specific.

Usually incremental build works. If not, one reason may be some file time set to far future.

Also try to use the internal builder.

[Lars Beiderbecke]

Thanks, Pavel! Changing the build from "external" to "internal" did activate the incremental build.

[Lars Beiderbecke]

Hm, there is only one problem: With internal builds, I no longer get the "used bytes" information, like this:

 text	 data	 bss	 dec	 hex	filename
 90284	 17816	 71924	 180024	 2bf38	proj.elf

Is there a way to get incremental builds with the external builder? Or that information with the internal builder?
