To build and install the AVR Helper Library, you need to have already installed the AVR GCC cross-compiler.
To install the AVR Helper Library, unpack the source tree. If you downloaded the *.tgz version, you can do this with the following command:
$ tar -xzf helper-1.3-src.tgz
Next, change directory to the head of the source tree that was just unpacked and run the make command:
$ cd helper-1.3 $ make
This should build the AVR Helper Library for all the supported AVR microcontrollers.
Once the libraries have been successfully built, you need to install the library components to a location where the AVR GCC compiler can find them.
The default installation directory prefix is /usr/local. If you wish to change this, you will have to edit the src/Makefile file in the source tree. In the Makefile, you’ll find a line that looks like this:
prefix = /usr/local
Change this line to desired directory prefix. For example, if you’re
using WinAVR , you will need to
change this this point to where WinAVR has been installed. For
example, if WinAVR has been installed in
change the prefix line to this:
prefix = c:/WinAVR
Finally, from the head of the source tree, or from the src directory, run this:
$ make install
