[ Upstream commit 88fe89a471 ]
Bartosz Golaszewski reports that when "make {menu,n,g,x}config" fails
due to missing packages, a temporary file is left over, which is not
ignored by git.
For example, if GTK+ is not installed:
$ make gconfig
*
* Unable to find the GTK+ installation. Please make sure that
* the GTK+ 2.0 development package is correctly installed.
* You need gtk+-2.0 gmodule-2.0 libglade-2.0
*
scripts/kconfig/Makefile:208: recipe for target 'scripts/kconfig/gconf-cfg' failed
make[1]: *** [scripts/kconfig/gconf-cfg] Error 1
Makefile:567: recipe for target 'gconfig' failed
make: *** [gconfig] Error 2
$ git status
HEAD detached at v5.4
Untracked files:
(use "git add <file>..." to include in what will be committed)
scripts/kconfig/gconf-cfg.tmp
nothing added to commit but untracked files present (use "git add" to track)
This is because the check scripts are run with filechk, which misses
to clean up the temporary file on failure.
When the line
{ $(filechk_$(1)); } > $@.tmp;
... fails, it exits immediately due to the 'set -e'. Use trap to make
sure to delete the temporary file on exit.
For extra safety, I replaced $@.tmp with $(dot-target).tmp to make it
a hidden file.
