Download and install avr-libc (an essential C library for AVR chips)ĭownload the current release of avr-libc from : ĭecompress the downloaded file and put the decompressed folder in your home directory When its done and you've washed your plate and silverware, install gcc.
This will take a long time so go have a sandwich Once the configuration is done, compile gcc. **thanks to Seth Raphael for the -disable-libssp ti p (substituting the name of the folder you decompressed for the gcc-4.2.0) gcc-4.2.0/configure -target=avr -enable-languages=c -disable-libssp Type: cd avrgcc-4.2 (or whatever you named your folder) Type: mkdir avrgcc-4.2 (substituting your gcc version for the 4.2) Next, c reate another directory to install gcc into. Open up a new Terminal window in your home directory, type cd gcc-4.2.0 and then ls to verify its all in there. Download & install gcc (the C compiler)įirst, download the current release of gcc from: currently thats gcc 4.2.0ĭecompress the downloaded file and put the decompressed folder in your home directory.

Only administrators can install software thats why the password is necessary. You will be prompted to enter your password. This will start an even longer compilation process This will start a long process that will spit out a lot of text. Type: cd binutils-2.17 (or whatever you downloaded) theb type in ls to verify everythings thereĬonfigure binutils for AVR. Open up a Terminal window and navigate to the binutils directory. You should now have a folder called binutils-2.17 which you should drag into your Home directory Save it into your home directory, not the desktop.ĭecompress the downloaded file and double click on it to decompress it (or use Stuffit Expander, in the Applications folder). Download & install binutils (an essential utility for the C compiler)ĭownload the current release of binutils from : (you can also go straight to the download site here) For these examples, we'll be using binutils-2.17.tar.gz but you should use whatever is most recent. (also with a few minor 'improvements' and images I've reduplicated it here in case the site goes down. Leah Buchley has an excellent tutorial, and you should follow it. (Note that this doesn't seem to work on Intel Macs for unknown reasons, we're investigating.) This is the 'old style' of installing avr-gcc, its longer and more tedious but you are guaranteed to have the latest version. The following steps are essentially the same for MacOS X or Linux, BSD or any other unixy OS. This is the advanced method, for when you need bleeding-edge development and hackability. The important thing is that at the end of the line is /usr/local/bin Now type in echo $PATH (for bash) or echo $path (for t/csh) you should get something like the following:
#CODEVISION FOR LINUX WINDOWS#
If the output is /bin/csh or /bin/tcsh then type the following command:Įcho 'set path = ($path /usr/local/bin)' > ~/.cshrcĬlose any Terminal windows and open up a new one. If the output is /bin/bash then type the following command:Įcho 'PATH=$PATH:/usr/local/bin' > ~/.bash_profile In the new Terminal window, type in echo $SHELL and press return In this prep-step you'll change the profile of your Terminal to add /usr/local/bin to the path.įind the Terminal program, you'll be using this to do most of this stuff. That means that when you type avrdude into the terminal it cant figure out where to look. Unfortunately that directory is not in the default path. The following two methods both place all of the files in the /usr/local/bin directory in the hard driver.
