Native Client (NaCl) not working in Chromium Dev

[Christopher Mason]

Native Client isn't working in Chromium Browser dev ppa. Everything that requires Native Client will either silently fail, or display a gray box with a plug icon.

Assigning to saiarcot, but I suspect it's WontFix for a while.

[Saikrishna Arcot (saiarcot895)]

Currently, this is intentional, because building the Native Client plugin into Chromium requires the use of a separate toolchain. While the toolchain is open-source, I'm having some trouble building it locally. When I do have it built successfully, I'll include Native Client using that toolchain.

[Chad Miller (cmiller)]

@saiarcot895, I too am interested in this, so I'll share any progress I make.

[Saikrishna Arcot (saiarcot895)]

Chromium with Native Client is now working for Trusty and newer on both the Chromium Beta and Dev PPAs.

Also, there is a duplicate of this bug: bug #882942. Should that be marked as a duplicate of this, or the other way around?

Still not working for me on Trusty with ppa:saiarcot895/chromium-beta. Look like native client extension exists, but none of NaCL applications are actually working. I tested Native Client SDK and even Hello World did not worked.

[dnord (dnord)]

Also dmesg get spammed with
traps: nacl_helper[18399] general protection ip:7fd7f5992227 sp:7ffdfd86f100 error:0 in libc-2.19.so[7fd7f5958000+1bb000]

[dnord (dnord)]

Looks like this problem is specific only to trusty. I've tested wily and NaCl was working fine.

Well, on Xenial the issue persists.

[Saikrishna Arcot (saiarcot895)]

Native Client is currently not being built, due to issues with the build system.

[vans163 (vans-163)]

This is quite unfortunate.

I am looking for NaCl support as well, javascript is just not fast enough for some things nor does it give you access to the amazing pepper api.

I will use Chrome for now but directing users to use Chrome vs chromium is really unfortunate.

[Or Schiro (orschiro)]

Can Chromium on Ubuntu please ship the Native Client?

I completely agree with @vans-163.

You are driving people from an open-source product to its proprietary alternative.

[Olivier Tilloy (osomon)]

Still valid. The packages are built with enable_nacl=false.

[Chris Coulson (chrisccoulson)]

I don't really think it's worth investing any time on this given that Native Client is deprecated and due to be removed in Q1 2018.

[Olivier Tilloy (osomon)]

Oh, I had missed that announcement. It doesn't make sense to invest time in supporting a feature that will soon be removed.

[Gerv (gerv-launchpad)]

NaCL will still be usable by Chrome Apps and extensions, for example Chrome Remote Desktop, which currently doesn't work with the Ubuntu version of Chromium. So there is still value in getting this working.

[Rolf Leggewie (r0lf)]

My issue is also with missing support for an app, called Vysor. It hasn't been ported yet and after reading through the annnouncement, it is true that NaCL support is scheduled to be dropped but *explicitly* not for apps.

Reopening.
