[Solved] Issues compiling hidapi

[technosf]

Hiya all,

I have a USB Relay 2 that I'm planning on using Darryls code (https://github.com/darrylb123/usbrelay) to use to switch on and off the power to a usb 3 hub and and hard drive from my plug.

On the way to compiling usbrelay, I need hidapi (http://www.signal11.us/oss/hidapi), and here I have met with a problem. Although I I have everything working on Suse (it has hidapi as a package), there are issues on Arch (where I need to compile hidapi from source): During linking, I'm getting this error - and being relatively new to Linux linking, would like help to address:

$this->bbcode_second_pass_code('', 'g++ -Wall -g hid-libusb.o ../hidtest/hidtest.o `pkg-config libusb-1.0 libudev --libs` -o hidtest
/usr/bin/ld: hid-libusb.o: undefined reference to symbol 'pthread_join@@GLIBC_2.4'
/usr/lib/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:25: recipe for target 'hidtest' failed
make: *** [hidtest] Error 1')

Hints/help would be greatly appreciated!

You could make you own package, a hint here
https://aur.archlinux.org/packages/hi/hidapi/PKGBUILD
Think it is essential you use the wiki to look up abs, aur, makepkg, swapfile, and pacman of course

Thanks Pepedog, that PKGBUILD worked great: I added "arm" to the architecture and it compiled up fine. The libraries got installed to /usr/local/lib, and I had to copy them to /usr/lib before I could compile the relay control software I got from github:

If you think this would be helpful to put in the ArchLinuxArm repetoire, please let me know what I can do to help make that happen.


Cheers,
