Building/editing the default sketch with Eclipse
This quick solution uses the existing libmaple makefile.

1. First, you need "eclipse IDE for C/C++ developpers" :
http://www.eclipse.org/downloads/
Download it, install it.

2. Launch it and accept the workspace it proposes by default
Close the "welcome" tab.

3. Import libmaple project in Eclipse
. File -> import
. C/C++ -> Existing Code as MakeFile project
Click Next
. Existing code location : select your 'libmaple' directory + OK
. Select Linux GCC (not sure what that does but cannot hurt)
Click Finish

4. Now you should get an error :
"make: *** no rule to make target 'all'..."

The libmaple Makefile expects the make default target to be "sketch"

Let's fix that :
Select menu "Project- > properties"
A property windows shows up.
Click on "C/C++ build" in the left tree.
Then click on the "Behaviour" tab inside the window.
In the field "build :", replace 'all' by 'sketch'.
Then click 'OK'.

Everything should compile now.
Uncheck "Project->Build automatically" if you don't want automatic build.

Use CTRL-B each time you want to build.

5. Now you can create an install target :
Menu "project-> make target-> Create..".
Type "install" in the first field then 'OK'.
To install "SHIFT-F9", select the target then "Build".

6. Start modifying main.cpp

Now you can enjoy:
. refactoring possibility of Eclipse
. The smart completion - CTRL-SPACE
. the "problems" tab which will redirect you where the error is
. the F3 key, to move you to your function/variable/define/class definition.
. The powerfull overlay, when your mouse fly over the code
... and much more...

Xavier,

Cool instructions!

Note that if you have a JTAG adapter, you can use Eclipse C/C++ visual debugger on your code:

Xavier,

Cool! Thanks for the note. Seems like a great idea for a HOWTO on the wiki:

Is there standalone script to merge .pdes in one .cpp file?

anton,

There's no standalone script. That happens here:

This is now a How To on the wiki:

Its formatting is kind of rough, but there it is!

Hi Everybody,

i was trying to do this and I get the following error before "everything should compile now"

"

**** Build of configuration Default for project SFM_002 ****

make sketch
================================================================================

Build info:
BOARD: maple
MCU: STM32F103RB
MEMORY_TARGET: flash

See 'make help' for all possible targets

================================================================================
/bin/sh: arm-none-eabi-gcc: not found

[CC] ./libmaple/adc.c
make: *** [build/./libmaple/adc.o] Error 127 "

i'm a n00b on ubuntu and i'm new to all the tool chains and most of the maple stuff as well. I can how ever compile and load file with libmaple using the command line tutorials.

any help as to how to resolve this would be much appreciated.

thanks.

Hi,

You skiped some steps explained here :
http://leaflabs.com/docs/unix-toolchain.html#toolchain-udev

Especially :

2. Fetch libmaple and Compiler Toolchain
....
$ cd libmaple
$ wget http://static.leaflabs.com/pub/codesourcery/gcc-arm-none-eabi-latest-linux32.tar.gz
$ tar xvf gcc-arm-none-eabi-latest-linux32.tar.gz
$ export PATH=$PATH:~/libmaple/arm/bin # or wherever these tools ended up

erm, oops, i flubbed that tar invocation in the docs. it should be:

$ tar xvzf gcc-arm-none-eabi-latest-linux32.tar.gz

fixed in https://github.com/leaflabs/libmaple/commit/24736e54ef5971ddfa78add19cb72b1090db7b5d

Hi,
thanks for the help, but the issue persists...

I've definitely did that step, other wise i wouldn't be able to compile from the command line(i think). Regardless I tried doing it over and i tried with the new tar command still no luck. I still get the same error.

my system is a T510 with Ubuntu 11.04. and I have these installed too "$ sudo aptitude install build-essential git-core wget screen dfu-util \ openocd python python-serial"

any help would be appreciated

Hi,

if I try to compile the sample libmaple I get this error:
'**** Build of configuration Default for project leaflabs-libmaple-0c1a52c ****

cs-make sketch
Das System kann den angegebenen Pfad nicht finden.
process_begin: CreateProcess(NULL, rm -rf build, ...) failed.
"================================================================================"
""
" Build info:"
" BOARD: " maple_RET6

""
" See 'make help' for all possible targets"
""
"================================================================================"
ECHO ist ausgeschaltet (OFF).
Syntaxfehler.
cs-make: *** [build/./libmaple] Error 1'

I changed also the Build command in Eclipse to cs-make.

Any idea whats wrong? I compile on Win7x64 (Leaflabs IDE works).

ratho,
```
process_begin: CreateProcess(NULL, rm -rf build, ...) failed.
                                   ^^^^^^^^^^^^
```
That's suspicious. It looks like something is trying to run the Unix command "rm", which is not available on Windows (at least, not at my WinXP CMD prompt). Perhaps the other users who have successfully gotten Eclipse working are on a Unix platform like OS X or Linux; they may also have Cygwin installed. I'm not sure. We haven't tried officially supporting Eclipse yet, mostly because we were sure to run into issues like these.

There's got to be something wrong with your PATH. Perhaps Eclipse isn't inheriting environment variables you set in a shell startup script?

I just encountered the "make: *** [build/./libmaple/adc.o] Error 127 " as well.
For some reason Eclipse refused to see arm-none-eabi-gcc even though I had the arm/bin folder in my path, and had it included in the path variables in Eclipse.

Anyway, I solved it by including the file itself in Path Variables:
Open Project Properties.
In Resources -> Linked Resources choose Path Variables
Make a new one pointing to ~/libmaple/arm/bin/arm-none-eabi-gcc (Depending on where you've installed libmaple you might need to point it somewhere else)

This fixed that problem for me, and I can compile and install from Eclipse.
