[ipxe-devel] src/util/get-pci-ids version.h, asm/linkage.h and generated/timeconst.h: No such file or directory

[Geert Stappers]

Hello,


The iPXE source tree has a script named src/util/get-pci-ids
that doesn't work for me.  I seek your advice to get it working.


I have three errors.  The first error is that my Linux source tree
has no `include/linux/version.h`

<error1text>
$ ./get-pci-ids /usr/src/linux/torvalds
Could not find /usr/src/linux/torvalds/include/linux/version.h.
/usr/src/linux/torvalds is probably no Linux kernel source tree.

I assumed that the script is outdated, hence I tried this change:

Now I'm stuck at

What do you suggest to do next to get this fixed?
