Simple AVR

Build

Typical installation instructions:

$ ./autogen.sh
$ ./configure --build=x86_64-unknown-linux-gnu --host=avr --prefix=$PWD/install
$ make
$ make check
$ make install

Usage

Once installed, the recommended procedure to include and link against savr is the use of pkg-config.

Each platform has its own savr library in a separate directory under ${prefix}/lib/savr (e.g. /usr/lib/savr/atmega328), while the include directory structure is common for all builds (pre-processor is used to include the proper files).

To build and link against savr, you just have to provide pkg-config with your target MCU, and it will provide you with all the proper compiler and linker flags.

$ avr-gcc -mmcu=atmega328 program.c -o program.o $(pkg-config --define-variable=mcu=atmega328 --cflags --libs savr)
$ avr-objcopy -O ihex program.o program.hex

For this to work, make sure that ${prefix}/lib/pkgconfig is in your PKG_CONFIG_PATH environment variable. That should be the case if you installed savr is a standard location.
