Chromium PDF view=fit parameter resolved but not for armhf

Hi all,

I have a question about chromium browser in raspberry pi 3 (armhf).
There is a known problem about viewing PDF in chromium with parameter view=fitH, fitV, since an update to Chrome, when certain types of plugins, known as NPAPI plugins like Adobe Reader were no longer be available. This may be why some of the plugins are no longer working. Now chromium uses its own pdf viewer.

I read that with pleasure maybe there will be a solution for my problem (missing view=fitH and view=fitV part of the PDF in chromium) on site, when developers tried to implement these viewing/missing parameters into current pdf-viewer.

I was writing to the implementator, because he is the owner of that ticket. He sent me a link where the changes is already in the latest Chrome build on the Dev channel. I can get it at
This is a developer version 64.0... I tried that in Windows, it is working correctly, but I couldn't install it to raspbian/debian in raspberry pi 3:
'package architecture (amd64) does not match system (armhf)'

What do you think, do you know about a website, where I can download chromium developer versions for raspberry pi 3, for system armhf (that contains this correction), or do you have any idea to solve my problem?

As far as I know, the developers of Raspbian ship their own version of chromium. You might want to ask them.

You tried to install a 64bit x86 atrchitecture package on an ARM platform. That cannot work. You need to use a armhf deb package. But the Raspbian guys do other modifications to optimize for RPi, so best to stick with that (and not the Debian version)

Hi pylkko,

I posted my problem on raspberry forums. And I wrote some mails to RB developers.
Unfortunately, I didn't get any answares. :(

I reckon, I have to build the newest chromium from src code is the the fastest way to solve the problem.
I found instructions about building chromium for ARM, it seems a little difficult to start :).

Since you are running the Cortex-A7 (ARMv7-A) version of the RPI, you should be able to compile armhf code from debian source (or other source). But I believe they do other stuff like make the video be hardware encoded and run under omxplayer and provide flash player plugin etc. However, IIRC these are distributed as a separate package called chromium-mods (or something). So, perhaps you could install that on top of your custom built Chromium.
