Attempt to build aplus-fsf-​4.22 (EnumTable​)

Attempt to build aplus-fsf-​4.22 (EnumTable​)

[Tom Szczesny]

In Gentoo Linux:

aplus-fsf-4.22/src/cxsys/eponymous.c      contains           #include
<sys/ioctl.h>
sys/ioctl.h                                                  contains
         #include <bits/ioctls.h>
bits/ioctls.h                                                contains
         #include <asm/ioctls.h>
asm/ioctls.h                                               contains
       #include <asm-generic/ioctls.h>
asm-generic/ioctls.h                                  has the
difinitions that are required.

Since I can't change cygwin, my plan is to put a copy of
asm-generic/ioclts.h into the aplus source package.

You're going to be disappointed.  You can't just make an ioctl magically
work by including a header file.

Which definitions are required?

That's a bad idea. Those values are Linux-specific. Your program might
compile, but is bound to fail at run time.
If an ioctl macro is not defined on Cygwin, it's because the
functionality is not implemented. In this case, sending a random
number to the ioctl function is not going to magically make it work.

asm-generic/ioctls.h contains #include <linux/ioctl.h>
Do you think that would work?
