install_tools - .TH "install_tools" 3 "Thu Aug 12 2010" "Version 1.6.8" "avr-libc"  

NAME

install_tools - .PP This chapter shows how to build and install, from source code, a complete development environment for the AVR processors using the GNU toolset. There are two main sections, one for Linux, FreeBSD, and other Unix-like operating systems, and another section for Windows.  

Building and Installing under Linux, FreeBSD, and Others

The default behaviour for most of these tools is to install every thing under the /usr/local directory. In order to keep the AVR tools separate from the base system, it is usually better to install everything into /usr/local/avr. If the /usr/local/avr directory does not exist, you should create it before trying to install anything. You will need root access to install there. If you don't have root access to the system, you can alternatively install in your home directory, for example, in $HOME/local/avr. Where you install is a completely arbitrary decision, but should be consistent for all the tools.

You specify the installation directory by using the --prefix=dir option with the configure script. It is important to install all the AVR tools in the same directory or some of the tools will not work correctly. To ensure consistency and simplify the discussion, we will use $PREFIX to refer to whatever directory you wish to install in. You can set this as an environment variable if you wish as such (using a Bourne-like shell):


  


$ PREFIX=$HOME/local/avr
$ export PREFIX


  

Note:

Be sure that you have your PATH environment variable set to search the directory you install everything in before you start installing anything. For example, if you use --prefix=$PREFIX, you must have $PREFIX/bin in your exported PATH. As such:


$ PATH=$PATH:$PREFIX/bin
$ export PATH

Warning:

If you have CC set to anything other than avr-gcc in your environment, this will cause the configure script to fail. It is best to not have CC set at all.

Note:

It is usually the best to use the latest released version of each of the tools.

GNU Binutils for the AVR target

The binutils package provides all the low-level utilities needed in building and manipulating object files. Once installed, your environment will have an AVR assembler (avr-as), linker (avr-ld), and librarian (avr-ar and avr-ranlib). In addition, you get tools which extract data from object files (avr-objcopy), dissassemble object file information (avr-objdump), and strip information from object files (avr-strip). Before we can build the C compiler, these tools need to be in place.

Download and unpack the source files:


$ bunzip2 -c binutils-<version>.tar.bz2 | tar xf -
$ cd binutils-<version>

Note:

Replace <version> with the version of the package you downloaded.

If you obtained a gzip compressed file (.gz), use gunzip instead of bunzip2.

It is usually a good idea to configure and build binutils in a subdirectory so as not to pollute the source with the compiled files. This is recommended by the binutils developers.


$ mkdir obj-avr
$ cd obj-avr

The next step is to configure and build the tools. This is done by supplying arguments to the configure script that enable the AVR-specific options.


$ ../configure --prefix=$PREFIX --target=avr --disable-nls

If you don't specify the --prefix option, the tools will get installed in the /usr/local hierarchy (i.e. the binaries will get installed in /usr/local/bin, the info pages get installed in /usr/local/info, etc.) Since these tools are changing frequently, It is preferrable to put them in a location that is easily removed.

When configure is run, it generates a lot of messages while it determines what is available on your operating system. When it finishes, it will have created several Makefiles that are custom tailored to your platform. At this point, you can build the project.


$ make

Note:

BSD users should note that the project's Makefile uses GNU make syntax. This means FreeBSD users may need to build the tools by using gmake.

If the tools compiled cleanly, you're ready to install them. If you specified a destination that isn't owned by your account, you'll need root access to install them. To install:


$ make install

You should now have the programs from binutils installed into $PREFIX/bin. Don't forget to set your PATH environment variable before going to build avr-gcc.

Note:

The official version of binutils might lack support for recent AVR devices. A patch that adds more AVR types can be found at http://www.freebsd.org/cgi/cvsweb.cgi/ports/devel/avr-binutils/files/patch-newdevices

 

GCC for the AVR target

Warning:

You must install avr-binutils and make sure your path is set properly before installing avr-gcc.

The steps to build avr-gcc are essentially same as for binutils:


$ bunzip2 -c gcc-<version>.tar.bz2 | tar xf -
$ cd gcc-<version>
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --prefix=$PREFIX --target=avr --enable-languages=c,c++     --disable-nls --disable-libssp --with-dwarf2
$ make
$ make install

To save your self some download time, you can alternatively download only the gcc-core-<version>.tar.bz2 and gcc-c++-<version>.tar.bz2 parts of the gcc. Also, if you don't need C++ support, you only need the core part and should only enable the C language support.

Note:

Early versions of these tools did not support C++.

The stdc++ libs are not included with C++ for AVR due to the size limitations of the devices.

The official version of GCC might lack support for recent AVR devices. A patch that adds more AVR types can be found at http://www.freebsd.org/cgi/cvsweb.cgi/ports/devel/avr-gcc/files/patch-newdevices

 

AVR Libc

Warning:

You must install avr-binutils, avr-gcc and make sure your path is set properly before installing avr-libc.

Note:

If you have obtained the latest avr-libc from cvs, you will have to run the bootstrap script before using either of the build methods described below.

To build and install avr-libc:


$ gunzip -c avr-libc-<version>.tar.gz | tar xf -
$ cd avr-libc-<version>
$ ./configure --prefix=$PREFIX --build=`./config.guess` --host=avr
$ make
$ make install

 

AVRDUDE


 

Note:

It has been ported to windows (via MinGW or cygwin), Linux and Solaris. Other Unix systems should be trivial to port to.

avrdude is part of the FreeBSD ports system. To install it, simply do the following:


# cd /usr/ports/devel/avrdude
# make install

Note:

Installation into the default location usually requires root permissions. However, running the program only requires access permissions to the appropriate ppi(4) device.

Building and installing on other systems should use the configure system, as such:


$ gunzip -c avrdude-<version>.tar.gz | tar xf -
$ cd avrdude-<version>
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --prefix=$PREFIX
$ make
$ make install

 

GDB for the AVR target

GDB also uses the configure system, so to build and install:


$ bunzip2 -c gdb-<version>.tar.bz2 | tar xf -
$ cd gdb-<version>
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --prefix=$PREFIX --target=avr
$ make
$ make install

Note:

If you are planning on using avr-gdb, you will probably want to install either simulavr or avarice since avr-gdb needs one of these to run as a a remote target backend.

 

SimulAVR

SimulAVR also uses the configure system, so to build and install:


$ gunzip -c simulavr-<version>.tar.gz | tar xf -
$ cd simulavr-<version>
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --prefix=$PREFIX
$ make
$ make install

Note:

You might want to have already installed avr-binutils, avr-gcc and avr-libc if you want to have the test programs built in the simulavr source.

 

AVaRICE

Note:

These install notes are not applicable to avarice-1.5 or older. You probably don't want to use anything that old anyways since there have been many improvements and bug fixes since the 1.5 release.

AVaRICE also uses the configure system, so to build and install:


$ gunzip -c avarice-<version>.tar.gz | tar xf -
$ cd avarice-<version>
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --prefix=$PREFIX
$ make
$ make install

Note:

AVaRICE uses the BFD library for accessing various binary file formats. You may need to tell the configure script where to find the lib and headers for the link to work. This is usually done by invoking the configure script like this (Replace <hdr_path> with the path to the bfd.h file on your system. Replace <lib_path> with the path to libbfd.a on your system.):


$ CPPFLAGS=-I<hdr_path> LDFLAGS=-L<lib_path> ../configure --prefix=$PREFIX

 

Building and Installing under Windows

Building and installing the toolchain under Windows requires more effort because all of the tools required for building, and the programs themselves, are mainly designed for running under a POSIX environment such as Unix and Linux. Windows does not natively provide such an environment.

There are two projects available that provide such an environment, Cygwin and MinGW/MSYS. There are advantages and disadvantages to both. Cygwin provides a very complete POSIX environment that allows one to build many Linux based tools from source with very little or no source modifications. However, POSIX functionality is provided in the form of a DLL that is linked to the application. This DLL has to be redistributed with your application and there are issues if the Cygwin DLL already exists on the installation system and different versions of the DLL. On the other hand, MinGW/MSYS can compile code as native Win32 applications. However, this means that programs designed for Unix and Linux (i.e. that use POSIX functionality) will not compile as MinGW/MSYS does not provide that POSIX layer for you. Therefore most programs that compile on both types of host systems, usually must provide some sort of abstraction layer to allow an application to be built cross-platform.

MinGW/MSYS does provide somewhat of a POSIX environment that allows you to build Unix and Linux applications as they woud normally do, with a configure step and a make step. Cygwin also provides such an environment. This means that building the AVR toolchain is very similar to how it is built in Linux, described above. The main differences are in what the PATH environment variable gets set to, pathname differences, and the tools that are required to build the projects under Windows. We'll take a look at the tools next.  

Tools Required for Building the Toolchain for Windows

These are the tools that are currently used to build WinAVR 20070525 (or later). This list may change, either the version of the tools, or the tools themselves, as improvements are made.

MinGW/MSYS

 <http://downloads.sourceforge.net/mingw/MinGW-5.1.4.exe?use_mirror=superb-east>
Put MinGW-5.1.4.exe in it's own directory (for example: C:\MinGWSetup)
Run MinGW-5.1.4.exe
Select 'Download and install'
Select 'Current' package.
Select type of install: Full.

Install MSYS-1.0.10.exe package.

 <http://prdownloads.sf.net/mingw/MSYS-1.0.10.exe?download>
Default selections
Batch file will ask:
It will display some messages on the screen, then it will display: 'Press any key to continue . . .'. Press any key.

Edit c:\msys\1.0\msys.bat

 Change line (should be line 41): 


        if EXIST rxvt.exe goto startrxvt
    


 to: 


        rem if EXIST rxvt.exe goto startrxvt
    


 to remark out this line. Doing this will cause MSYS to always use the bash shell and not the rxvt shell.

Note:

The order of the next three is important. Install MSYS Developer toolkit before the autotools.

MSYS Developer Toolkit version 1.0.1
This is needed to build avr-libc in MinGW.
<http://downloads.sourceforge.net/mingw/msysDTK-1.0.1.exe?use_mirror=internap>
Single file installer executable. Install.

autoconf 2.59 from the 'MSYS Developer Toolkit' release
autoconf 2.59/2.60 is needed to build avr-libc in MinGW.
<http://downloads.sourceforge.net/mingw/msys-autoconf-2.59.tar.bz2?use_mirror=internap>
Extract to c:\msys\1.0

automake 1.8.2
automake 1.8/1.9 is needed to build avr-libc in MinGW.
<http://downloads.sourceforge.net/mingw/msys-automake-1.8.2.tar.bz2?use_mirror=internap>
Extract to c:\msys\1.0

Install Cygwin
Install everything, all users, UNIX line endings. This will take a *long* time. A fat internet pipe is highly recommended. It is also recommended that you download all to a directory first, and then install from that directory to your machine.

Note:

GMP is a prequisite for building MPFR. Build GMP first.

Build GMP for MinGW
Version 4.2.3
<http://gmplib.org/>
Build script:


        ./configure  2>&1 | tee gmp-configure.log
        make         2>&1 | tee gmp-make.log
        make check   2>&1 | tee gmp-make-check.log
        make install 2>&1 | tee gmp-make-install.log
        

GMP headers will be installed under /usr/local/include and library installed under /usr/local/lib.

Build MPFR for MinGW
Version 2.3.2
<http://www.mpfr.org/>
Build script:


        ./configure --with-gmp=/usr/local 2>&1 | tee mpfr-configure.log
        make         2>&1 | tee mpfr-make.log
        make check   2>&1 | tee mpfr-make-check.log
        make install 2>&1 | tee mpfr-make-install.log
        

MPFR headers will be installed under /usr/local/include and library installed under /usr/local/lib.

Install Doxygen
Version 1.5.6
<http://www.stack.nl/~dimitri/doxygen/>
Download and install.

Install NetPBM
Version 10.27.0
From the GNUWin32 project: <http://gnuwin32.sourceforge.net/packages.html>
Download and install.

Install fig2dev
Version 3.2 Patchlevel 5
From WinFig 2.2: <http://www.schmidt-web-berlin.de/winfig/>
Unzip the download file and install fig2dev.exe in a location of your choice.

Install MiKTeX
Version 2.7
<http://miktex.org/>
Download and install.

Install Ghostscript
Version 8.63
<http://www.cs.wisc.edu/~ghost/>
Download and install.
In the subdirectory of the installaion, copy gswin32c.exe to gs.exe.

Set the TEMP and TMP environment variables to c:\temp or to the short filename version. This helps to avoid NTVDM errors during building.

 

Building the Toolchain for Windows

All directories in the PATH enviornment variable should be specified using their short filename (8.3) version. This will also help to avoid NTVDM errors during building. These short filenames can be specific to each machine.
