Bef installation instructions
|
|
|
|
What you need:
|
|
1) The C32 Suite installed and access to copy them to your unix box
|
|
2) A installed/functioning C32 GCC compiler for your unix box (See
|
|
http://www.paintyourdragon.com/uc/osxpic32/index.html but read below for
|
|
important info)
|
|
|
|
3) The pic32 port of newlib
|
|
(http://svn.neostats.net/svn/pic32-newlib/Trunk/)
|
|
|
|
What my assumptions are:
|
|
1) I'm not installing to the system wide directory, but to a private home
|
|
directory (hence, the c32 install.sh script is not valid)
|
|
|
|
What you do:
|
|
1) Firstly, follow the instructions to build your GCC version that is
|
|
contained on Phillip Burgess's page above.
|
|
|
|
(I made one change to the build.sh directory - On Line 48, changed the
|
|
--prefix option to "/home/pic32/". I suggest for the moment you do the same,
|
|
as I don't know if the newlib files will mess up your System Include files
|
|
or not - If you do this, you also should add the new /home/pic32/bin
|
|
directory to your Path)
|
|
|
|
2) Ignore the install.sh script that Phillip Burgess provides, as we will be
|
|
using only a limited number of files (for now) from the C32 Suite
|
|
|
|
3) In the GCC directory, you can execute "make install" and this should
|
|
install the GCC files into directories such as /home/pic32/bin and
|
|
/home/pic32/lib etc
|
|
|
|
4) From the C32 Suite, Place the following files (preserving directory
|
|
structures etc) into the following directory:
|
|
/home/pic32/pic32mx/include
|
|
|
|
(from C32 Suite)
|
|
pic32-libs/include/cp0defs.h -> /home/pic32/pic32mx/include/cp0defs.h
|
|
pic32-libs/include/peripheral/* -> /home/pic32/pic32mx/include/peripheral/*
|
|
pic32-libs/include/p32xxxx.h -> /home/pic32/pic32mx/include/p32xxxx.h
|
|
pic32-libs/include/plib.h -> /home/pic32/pic32mx/include/plib.h
|
|
pic32-libs/include/proc/* -> /home/pic32/pic32mx/include/proc/*
|
|
pic32-libs/include/sys/attribs.h -> /home/pic32/pic32mx/include/sys/attribs.h
|
|
|
|
pic32-libs/c/startup/crt0.S -> (the directory where you are reading this
|
|
file)/newlib/libgloss/pic32mx/crt0.S
|
|
|
|
(you may need one or two other files, please let me know if thats the case)
|
|
|
|
5) Now, you can build newlib ->
|
|
cd into the newlib directory and type:
|
|
"./configure --prefix=/home/pic32/ --target=pic32mx --enable-target-optspace --disable-newlib-atexit-alloc"
|
|
(you can read about the options i used in the newlib documentation)
|
|
|
|
6) Now type "make" and go have a cup of coffee, or a beer :)
|
|
|
|
7) When finished, type "make install"
|
|
|
|
8) optional, edit the GCC Spec file to specify what default libs to include:
|
|
/home/pic32/lib/gcc/pic32mx/3.4.4/specs
|
|
Go to Line 51 and Change it so it looks like this:
|
|
--start-group -lc -lm -le -lpic32 %{!mno-peripheral-libs:-lmchp_peripheral %{mprocessor=*:-lmchp_peripheral_%*}} --end-group
|
|
(basically, remove -ldsp and replace with -lpic32)
|
|
|
|
Now, you are ready to go!
|
|
|
|
(for a Example Makefile, look in the example directory)
