Re: [PATCH v3] scripts: Makefile.lib: generate dsdt_generated.c instead of dsdt.c

Hi,

Am Di., 22. Feb. 2022 um 14:55 Uhr schrieb Philippe Reynes philippe.reynes@softathome.com:

There is a conflict between the static file lib/acpi/dsdt.c and the file dsdt.c generated dynamicaly by scripts/Makefile.lib. When a mrproper is done, the static file dsdt.c is removed. If a build with acpi enabled is launched after, the following error is raised:

CC lib/acpi/acpi_table.o make[2]: *** No rule to make target 'lib/acpi/dsdt.asl', needed by 'lib/acpi/dsdt.c'. Stop. scripts/Makefile.build:394: recipe for target 'lib/acpi' failed

To avoid such error, the generated file is named dsdt_generated.c instead of dstdt.c.

This issue can also be seen when doing a make clean and do a git status

-- 8< -- Changes not staged for commit: (use "git add/rm <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) deleted: lib/acpi/dsdt.c -- 8< --

After applying this patch this cannot be seen anymore.

Changelog: v3:

• update comments in file scripts/Makefile.lib
• add changelog

v2

• change generated file name (dsdt_generated.c) instead of changing the name of the static file
• NOTE : forgot to call it v2 and forgot changelog
