Hello at all,

Since versions 4.12 btrfs-progs is complicated to cross compile for
other systems.
The problem is, that this version includes mktables, which needs to be
compiled for the host system and executed there for the creation of
tables.c.
Are there any changes planed for the next version of btrfs-progs to make
the cross compiling as simple as in the past? A included tables.c for
example?
Including tables.c seems quite crazy for me.
Just check how many lines tables.c has.
If we screw up any number of it, RAID6 is screwed up and we will never
find the bug by reviewing the such meaningless numbers.
We could enhance the makefile to use host-cc to compile and execute mktable.
But it may make the makefile more complicated just for one file.
(Well, I just don't want to screw traditional Makefile/configure any more)
Another solution is to generate tables.c using scripts, other binary
executable.
I'll try to port mktable to bash or python, which should solve the
problem withouth further complicating makefile.
(And maybe I can update kernel too, but kernel has its host-cc and
cross-cc already distinguished well, so it may not help much)
Thanks,
Qu
Best regards
