8 years ago It seems that the reason why dumpconf is throwing can't open file "arch/x86/Kconfig" is because it doesn't understand when the current working directory is not the Linux source directory:
~/dev/kconfigreader$ binary/dumpconf ../linux/Kconfig
setting archusing arch x86
../linux/Kconfig:11: can't open file "arch/x86/Kconfig"
~/dev/kconfigreader$ cd ../linux
~/dev/linux$ ../kconfigreader/binary/dumpconf Kconfig
.

...So I manually generated the out.rsf file by executing ~/dev/linux$ ../kconfigreader/binary/dumpconf Kconfig > ../kconfigreader/out.rsf. I then deleted the dumpconf step from KConfigReader so it wouldn't overwrite it with an empty file:

writing model
writing dimacsIt's at least a working workaround.
I have compiled
dumpconfusing themake.shscript against the kernel source tree I have downloaded. The version of it is:However, when I then tried to run kconfigreader, it crashed with the following error:
Which I assume is due to the content of
out.rsf:When running only
dumpconf, I'm getting the same error:So it's obvious that
dumpconfdoesn't behave correctly. Is it because the kernel version is too new? I have tried against 3.6.0 too, and it neither worked. What version are you using it against?Thanks, Daniel
