Installing NodeJS 10 or above #153

Closed olivierpichon closed 4 years ago

olivierpichon commented 4 years ago

Hello there!

We tried to compile Node 10 from source and it failed after building Torque (we got Illegal instruction).

We noticed this past commit on this repo:

https://github.com/siemens/meta-iot2000/commit/eec8f87114d371819b15cde921b9ff8c0ec75052

Is any higher version than Node 8 still not supported?

If not, we can't seem to find a package of Node 8 already built (.ipk) file? There is no other way than compiling it from source? The last ipk file we were able to find is http://iotdk.intel.com/repos/iot-cloud-dev/iotdk/3.5/i586/nodejs-dev_v4.4.3-r1.0_i586.ipk

And when trying to compile Node 8.16.2, we are getting:

import decimal
ImportError: No module named decimal

So far dealing with Node dependencies on the device has been unfortunately a great pain. :( Thanks a lot for your help!

NodeJS requires patches in order to enable support for the Quark processor (i.e. an SSE-free 586-class CPU). We have those for the 8 series as encoded in this layer, but work for 10 only started. It's not trivial - again - because a lot changed in the V8 engine between the versions used in NodeJS 8 and 10, and those changes unfortunately affect the processor support as well. I cannot provide an estimate yet when this can be finished.

Note that the Intel repo is dead for a long time now. It only provided usable packages for the very first IOT2000 image version and was then already abandoned by Intel.

Thanks @jan-kiszka !

So if this Intel repo is dead, which repo should we use to get Node8? Is there any repo we could use to pull it from? Alternatively, is there a guide we could use to install Node8 from source? On the poky-iot2000 v2.6.0 image example we installed, it does not seem to come with it and as stated before, compiling it (v8.16.2) fails.

Thanks again!

Node JS 8.16.0 comes with the example image 2.6.0, see https://github.com/siemens/meta-iot2000/tree/master/meta-iot2000-example/recipes-devtools/nodejs for the related recipe.
