make failure about kabi-dw HOT 6 CLOSED

I got past this issue by -fms-extensions. GCC does not recognize the anonymous structures without this extensions.

However, the build failed at the following error after that.

I have elfutils installed.

Am I missing something ?

Hello Atish,

Thanks for looking!

In general it seems that you're using significantly older toolchain (gcc, bison) than us. So the first solution is that you'd use something more recent.
We'll look into this anyway, we might be able to remove the anonymous types to get it compilable by older tools.

Thanks!

from kabi-dw.

Sure. I will do that.
Can you please provide the recommended gcc & bison versions ?

On my system:
$ gcc --version
gcc (GCC) 6.3.1 20161221 (Red Hat 6.3.1-1)
$ bison -V
bison (GNU Bison) 3.0.4

from kabi-dw.

Thanks. Mine was pretty old.
Now it works.

Atish,
We just pushed a major redesign of the tool. Now we store most of the information in memory rather than in files. So for a full kernel run including all modules you might need up to 250MB of memory, but the benefit is that the tool runs few times faster. Our current testing is able to generate all the type information of the kernel in about 30 seconds. Please give it a try!
Because of a screwup on my side I had to also change the last 3 commits in the history, so please make sure to reset to the last common ancestor and pull again. Thank you!
