building native_client failed

[StanPlatinum]

Greetings!

Great work! Big fan!

When I tried to build it, the following lines came out...

➜ ryoan git:(master) ✗ cd native_client && make J=2
./scons MODE=opt-ryoan,nacl platform=x86_64 -j2
scons: Reading SConscript files ...

Do you have any thoughts on it? Thanks!

Hi! Thanks for trying it out. Apologies for the long silence on this.

If you still care: Looks like a rogue .gitignore line was causing part of the problem, the release was missing some files necessary to build. Totally my bad.

Thanks very much @tylershunt , for the reply!

The previous problem gone yet another came out, unfortunately...

Ah more missing files, (sorry I'm not set up to build this myself right now). I pushed some more files, try again?

[StanPlatinum]

Thanks a ton!

After I installed libatlas-dev and add /usr/lib/x86_64-linux-gnuthe LIBRARY_PATH, two dependency issuses have been solved. The building script can run for a while.

But seems some files still missing. I got the following that cut from the output of cd native_client && make J=2

Oh that's good! it got to the testing phase so it was at least built. Not sure why that input file is missing. I should have time to bring up a fresh test environment this weekend and see if I get the same thing.

[StanPlatinum]

Thanks @tylershunt

Take your time! I am always aware that rebuilding a functional environment is tedious and time-consuming. Don't worry, not trying to rush you.

Just out of curiosity, does Ryoan use some techniques to prevent side- or covert channels? I know hardware-based side channel is difficult to prevent but I am curious about what Ryoan can do on mitigating the software-based covert channels?

BTW, do you think this question should be raised on another issue since it seems irrelevant to the building issue?

[StanPlatinum]

@tylershunt Dear Tyler,

Still cannot build it...

Just bumping this thread in case you didn't see it.
