Build instructions

Regular build

To be able to build the library on a Raspberry Pi itself, you need to do the following:

  • Install the packages tcl8.5-dev, libi2c-dev, and autoconf, if necessary: sudo apt-get install tcl8.5-dev libi2c-dev autoconf
  • Go to the source directory: cd piio
  • Get the standard tclconfig files: wget -qO- http://core.tcl.tk/tclconfig/tarball/tclconfig.tar.gz | tar xzv
  • Create the configure script from configure.in: autoconf
  • I prefer to build in a separate directory: mkdir build;cd build
  • Run configure: ../configure --with-tcl=/usr/lib/tcl8.5
  • Build the library: make
  • Optionally install it: sudo make install

Cross compiling

Compiling on the Raspberry Pi itself is slow. Since the code of the piio library isn't very big, it's not a big problem. But of course, it's also possible to cross compile the library on a more powerful linux system. To do that, you need a cross compile environment. One way to create that is using the build-cc script. Make sure you have installed all necessary development packages before running the script.

You'll also need a stubs library compiled for a Raspberry Pi. You can generate that by cross compiling Tcl first.

Next, run the following commands:

wget -qO- http://core.tcl.tk/tclconfig/tarball/tclconfig.tar.gz | tar xzv
autoconf
mkdir build
cd build
eval $(~/root/cross-compilers/setup-cc armv6-hardfloat-linux-gnueabi)
../configure -host=armv6-hardfloat-linux-gnueabi --with-tcl=~/rpi/tcl8.5.15/build
make

How do I download all the files for this package, don't seem find anything that lets me do it, or gives me some instructions, on what to do :/

You can download the files the same way as all chiselapp projects (if enabled). The direct link for piio trunk is: http://chiselapp.com/user/schelte/repository/piio/tarball/piio.tar.gz

If you want a specific version, click on the desired check-in on the timeline tab and then click the preferred download format (Tarball or ZIP archive).
