Does not work on ARM Platforms

[kop316]

Hello,

I attempted to install this on my Novena laptop which has a Freescale ARM IM.x 6 CPU (Debian Stretch armhf). When installing from the website, it says it is incompatible. Upon looking at the source code, I suspect that is because the C code packaged in the XPI is compiled to x86_64. I suspect then that if anyone runs this on a Raspberry Pi or similar platform, they will get the same issue.

I attempted to follow the instructions for compiling and packing myself, but I kept getting the error of "This package is corrupt."

To compile, I ran

$cd c_src $cmake ./ $make & make install $cd ../ext $zip -9r ../u2f.xpi *

I also attempted to run the "make-xpi.sh" from the script folder, but it said it could not access the "ext" Folder. I moved it up to the root folder, and it ran, but I also got the same issue of the package being corrupt.

I am running Firefox 50.1.0, and I disable the code signing as well.

Any help on how to properly compile would be appreciated!

Yes extension only contains binaries for x86/x86_64 architectures so it won't work on arm processor. I'm not sure why calling scripts/make_xpi.sh doesn't work for you, maybe some problem with your zip? Would you be able to upload that xpi file somewhere so i could take look at it? Maybe i would be able to figure out whats wrong with it.

u2f.zip

Hello, per your request, here is the xpi file. I changed the extension to .zip so github would upload it.

Thank you for your help by the way!

So I checked, for some reason only the bin folder is going into that xpi, I manually ran the

zip -9r ../u2f.xpi *

command. I got this updated one:
u2f_updated.zip

But it still complains that is is incompatible with Firefox 50.1.0, even though the one you built worked for my x86 machine.

For fun, I also tried adding the bin folder from mine to the official one you have and tried installing that, but I got the same error again.
u2f_support_add_on-1.0.1-fx-linux.zip

I think you need to add targetPlatform inside ext/install.rdf, i am not 100% sure which one will work for your platform, arm android is using arm-eabi-gcc3, maybe it will works for you too.

Hello,

So I tried your advice and I added "Linux_armv7l-gcc3" to the targeted platforms, but i still got the incompatible error. The other thing I tried was to just make the targeted platform "linux", and while I got it to install, it would not work properly. I did a bit of googling to try and read about targeted platforms for plug ins, but I had no such luck. Is there a plce you could recommend to look at it?

Thank you for your help once again!

It probably is unable to locate your binary (you need to place it in correct directory in ext/bin), if you check extension logs after you try to perform u2f operation (go to add-ons window, and click on preferences button in u2f extension section, on add-on preference panel click on show logs) this should give you path where it expects to find it.

Sorry it took so long to get back to you, life got in the way.

You were correct, the xpi bin file was in "Linux", not "Linux_armv7l-gcc3". I renamed the folder and the extension works! Thank you for the help
