... and the RAM function I run will show FREE RAM go up alot when converting to flash memory storage.

Code:

int freeRam(void)
{
  extern int  __bss_end;
  extern int  *__brkval;
  int free_memory;
  if((int)__brkval == 0) {
    free_memory = ((int)&free_memory) - ((int)&__bss_end);
  }
  else {
    free_memory = ((int)&free_memory) - ((int)__brkval);
  }
  return free_memory;
}
}

Had tried that a while ago. I could not figure out how to get __bss_end and __brkval defined...

You might also need the following line for uint16_t
#include <stdint.h>

uint16_t arrayname[1000];

cmaglie has done this already:
see https://github.com/arduino/Arduino/issues/1317

If you manage to run the version from github it should work,
*IF* you manage...
  (as I still don't)

may you update your repository and retry?

I did a 'git pull' and retried, but still got an error.

Tried it a second time (that's why the local repo was up-to-date) and put the log here:
http://paste.debian.net/247200

edit: 'gitb' in the paste is a local alias for 'git branch'.
        so I'm on branch ide-1.5.x

Code:

dada@i5:~/Arduino$ gitb
* ide-1.5.x

edit2: as the above link was about to expire I replaced it by a new one,
         expires 90d

you need to make the JAVA_HOME point to a JDK, currently it points to a JRE.

After tinkering a bit I have installed debian package 'default-jdk' and 'ant build' runs fine now.
But I still get the same error as from the nightly build, quoted in the second post of this thread.

Code:

/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by /home/dada/arduino-nightly/lib/librxtxSerial.so)

Does this mean that the new Arduino ide depends on a newer glibc version than I have on Debian Wheezy?

opened an issue to keep track of this:
https://github.com/arduino/Arduino/issues/1342

as always, if someone wants to try an implementation, I'll be happy to merge it.

Left a note about me using
#define digitalPinHasPWM(p)         ((p) >= 2 && (p) <= 13)

I will probably raise issues on other macros missing, like:
portModeRegister

and then I did not find out yet how to use these:
- digitalPinToPort
- digitalPinToBitMask
any pointers very welcome


Thanks a lot for your help,
very much appreciated.

Here's what works for me:

Thanks a lot, I did not know about ant.
So this is a huge step forward.

'ant build'  fails, why?

Before asking tons of questions about the IDE and the Due I want to make sure I use the newest version for my testing. I'm feeling quite dumb, as I did not find out how to start the thing yet.https://github.com/arduino/Arduino

Didn't come further with this one, still interested in hints...

I have found nightly builds on http://arduino.cc/en/Main/Software
(how could I have overlooked them before?)
and thought this would be an easy solution...
but no, not *that* easy 

On Debian/Wheezy 64bit I'm getting:

Code:

dada@i5:~$ ./arduino-nightly/arduino

Is that a library that is too old on updated Debian Wheezy?
Or what's wrong?

Before asking tons of questions about the IDE and the Due I want to make sure I use the newest version for my testing. I'm feeling quite dumb, as I did not find out how to start the thing yet.https://github.com/arduino/Arduino

* I got branch ide-1.5.x as a zip file from https://github.com/arduino/Arduino
   Is this the right branch to get?

* I cannot find an arduino executable in the extracted files, do I have to build it first?

Help appreciated.

* OutOfLine hoping for the "as-soon-as-I-hit-send-I-realized-the-answer" effect...

It would be easy to write one using the data on which pins have PWM, a function with a switch to return TRUE if it matches one, FALSE if not.

Sure,
but I think as the Arduino IDE does #define it for the other Arduinos it *would be* nice for the user to find that defined also on the Due. Or doesn't it make sense for that chip? (and if so, why?).

btw:  How can I detect the Due?
#ifdef  __SAM3X8E__ or is there something more specific?

The macro digitalPinHasPWM seams to be missing on Arduino 1.5.2

Can it be defined for the due?

I've fix same issue on my Ubuntu Studio 12.10 64bit by installing only two packets:

Code:

sudo apt-get install libc6:i386
sudo apt-get install libstdc++6:i386

I don't like to install ia32libs package since it take some major change in system [...]
Hope it helps.

oh, thanks a lot, that *did* help!

looking forward to finally being able to try some of my programs on the due

probably installing the "ia32-libs" debian package may solve the problem.
@OutOfLine, please confirm if this fix works for you.

unfortunately no, aptitude leaves me in dependency hell
might be my system

i plan to do another Debian Wheezy install on another system soon, will try there again.

thanks for you help.

@cmaglie   Please excuse the long answer time, was mostly away from computers a few days.

I forgot to ask: have you enabled verbose compile and upload [...]

Oh, I should have thought about this, sorry. Had tried shift compile, at least.
