This article is for reference only. To be revised with instruction for installing on /mnt/storage partition instead of chumby's / read-only filesystem.
Here's a HOWTO on setting up Phigets C development environment on chumby.
Install GCC
- SSH into your device [view guide].
- type 'gcc' (without quote), you'll be prompt to download & install gcc package. You'll see something like this
chumby:~# gcc GCC isn't on this device by default, but it's possible to download a package and install it. If you like, we can try fetching one from http://files.chumby.com/hacks/falconwing_toolchain.sh and installing it. Install toolchain? [Y/n] Y
It'll take a couple of minutes.
Install libusb & Phidgets library
- Download source code for libusb 0.1.12 here
- Download source code for Phidgets library here
- Download libstdc++.la file and save on a USB thumdrive (This is required by older libtool)
- Copy both libraries on to USB thumbdrive
- Connect the thumbdrive to your chumby
- Copy & extracted libraries source files to /mnt/storage
cp /mnt/usb/libusb-0.1.12.tar.gz /mnt/storage cp /mnt/usb/libphidget_2.1.7.20110203.tar.gz /mnt/storage cd /mnt/storage tar xvf libusb-0.1.12.tar.gz tar xvf libphidget_2.1.7.20110203.tar.gz
- Make chumby root filesystem writable and copy libstdc++.la (it's a tiny text file) to /lib to be used by libtool while compiling
mount -o remount,re / cp -r /mnt/usb/libstdc++.la /lib mount -o remount,ro /
- Configure & compile libusb
cd /mnt/storage/libusb-0.1.12 ./configure make
- Copy header file & compiled libusb to libphidget folder
cp ./usb.h /mnt/storage/libphidget-2.1.7.20110203 cp ./.libs/libusb.a /mnt/storage/libphidget-2.1.7.20110203
- Configure & compile & install Phidgets library
cd /mnt/storage/libphidget-2.1.7.20110203 ./configure make
Compile Phidgets examples
- Download Phidgets Linux examples from here
- Get it on your chumby device with a USB thumbdrive as above
- Copy header file & compiled libphidget to examples folder
cd /mnt/storage/libphidget-2.1.7.20110203 cp ./phidget21.h /mnt/storage/phidget21-c-examples-2.1.7.20110203 cp ./.libs/phidget21.a /mnt/storage/phidget21-c-examples-2.1.7.20110203
- Configure & compile & all examples
cd /mnt/storage/phidget21-c-examples-2.1.7.20110203 ./configure make
That's it. Now you have a development environment to compile C/C++ code on your chumby. Try connecting Phidgets to chumby and run one of the examples.
Use 'gcc' directly to compile your own Phidgets application
gcc MyPhidgets.c -o MyPhidgets -lphidget21
Clean up
- Delete downloaded tarball
rm /mnt/storage/libusb-0.1.12.tar.gz rm /mnt/storage/libphidget_2.1.7.20110203.tar.gz
