node-gyp build fails about pigpio

[dkebler]

I did have the daemon running so per your instructions I stopped it and disabled it in systemd, but building again I get the same errors

[fivdi]

Can you post the exact command used to perform the install and the complete output of that command please?

[fivdi]

I would imagine that an attempt is being made to install an old version of pigpio. Please try with the latest version of pigpio which is v0.5.1.

[dkebler]

I assume you mean pigpio itself since the above is complete output from npm when running npm install pigpio

I did...

wget abyz.co.uk/rpi/pigpio/pigpio.tar
tar xf pigpio.tar
cd PIGPIO
make
sudo make install

from pigpio site. It does throw some warnings. See below

I found there was some pigpio loaded from the orginial image says 1.30-1-xenial?? so I purged that

What exact files are you using in what linux directory Is is /usr/local/???. Only the daemon has a cli that reports a version and it says version 61 so kinda hard to determine the version after install.

this is what sudo make install says

install -m 0755 -d                /opt/pigpio/cgi
install -m 0755 -d                /usr/local/include
install -m 0644 pigpio.h          /usr/local/include
install -m 0644 pigpiod_if.h      /usr/local/include
install -m 0644 pigpiod_if2.h     /usr/local/include
install -m 0755 -d                /usr/local/lib
install -m 0755 libpigpio.so      /usr/local/lib
install -m 0755 libpigpiod_if.so  /usr/local/lib
install -m 0755 libpigpiod_if2.so /usr/local/lib
install -m 0755 -d                /usr/local/bin
install -m 0755 pig2vcd           /usr/local/bin
install -m 0755 pigpiod           /usr/local/bin
install -m 0755 pigs              /usr/local/bin

make output

I the the pigpio c library has a version function, but it doesn't look like you provided a binding for that so I can see what version pigpio node thinks it's using?

[fivdi]

I don't think there's an issue with the pigpio C library. It's the pigpio JS package that's causing the issue. Is that really the complete output of npm install pigpio? As in every single character of output?

Also, does the directory where npm install pigpio is being called from contain a package.json file? If so, what are the contents of that file?

[dkebler]

You were right it was the version.

---

I am using pigipo as a dependency in a package to the code I am running. I have a headless setup so I actually code on my main box and it syncs the packages I am working on to node_modules on the main code on the rpi. So I obviously can't do an install on that machine but rather later with npm install without save on the RPI. That means I have to hand code the package into package.json. Not knowing the version I just put in ^0.0.1 assuming npm would pick up the latest....it didn't. Just my misunderstanding of how npm uses semiversions. I put in "0.5.1" and all is well....:-). I better read up on npm semiversion useage again!

BTW I have done this with epoll, and ic2-bus successfully so was kinda scratching my head.

Good to hear it's working now :)
