Can't find pololu/orangutan.h

[louisstraub]

Hello everyone, this is my first day with the 3PI. It was a bumpy ride but I managed to install the hardware and software for the 3PI. I also was able to run the sample program to make the LED blink. My problem is that I want to try other sample programs but they #include pololu/orangutan.h I've tried everything but I can't seem to get that header from any of the sources listed in the documentation. I tried using OrangutanLCD.h but I get ../orangutanLCD.h:35: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'OrangutanLCD'. I'm not quite sure what the error means so I can't take any action. If some one can possibly direct me to or attach the #include pololu/orangutan.h header I would greatly appreciate the help as I would like to continue learning about the 3PI. Thanks in advance to all who respond...........

Hello,
It sounds like you have downloaded but not actually installed the Pololu AVR Library. Please confirm that you have followed the instructions here.

I have a directory WINAVR-20100110/AVR/INCLUDE/POLOLU which has the same files as the documentation shows, but there still is no pololu/orangutan.h. I'm not super technical, so please excuse what may seem to be simjple questions. If this is not the correct directory, I'm not sure where to go from here. But I did follow the instructions. Could you try to send me the header. It might be a temporary fix until I figure out where I might have made a mistake. Thanks for responding............

[paul]

When you say you have the "same files", does that include orangutan.h, which is listed in that screenshot? If not, there is something wrong with your installation. If so, please post the output from the compilation that failed for you so we can look at the actual error message.

I would like to show you what I got when I INSTASLLed the files. This is what I got when I ran INSTALL as Administrator from a DOS Window. According to the output, the installation was good. So in theory, the files exist. I'll recompile and send you the output. Thanks.....

This is the build output when I use OrangutanLCD.h for the header. I hope this helps.......

Saying "in theory, the files exist" is not helpful. Does orangutan.h exist or not? Also, OrangutanLCD.h is not what you are supposed to be including, and I thought you knew that. Please post the error you get when compiling our examples without changing them.

I apologize for my wording. I'm not trying to make extra work for you.

I'm trying to use the 6.f. Orangutan LCD Control Functions program from the Pololu AVR C/C++ Library User's Guide.
The sample program calls for #include <pololu/orangutan.h>. I'm using AVR Studio 4. These are the errors I get
when I compile/build the program. I have made no changes to the program.

rm -rf LCD.o LCD.elf dep/* LCD.hex LCD.eep LCD.lss LCD.map

Yes, I do have orangutan.h in my WINAVR-20100110/avr/include/pololu directory. The contents of the file is

#include <pololu/analog.h>
#include <pololu/buzzer.h>
#include <pololu/time.h>
#include <pololu/motors.h>
#include <pololu/lcd.h>
#include <pololu/leds.h>
#include <pololu/pushbuttons.h>
#include <pololu/qtr.h>
#include <pololu/encoders.h>
#include <pololu/resources.h>
#include <pololu/digital.h>
#include <pololu/servos.h>
#include <pololu/pulsein.h>
#include <pololu/OrangutanSerial/OrangutanSerial.h>
#include <pololu/OrangutanSPIMaster/OrangutanSPIMaster.h>
#include <pololu/OrangutanSVP/OrangutanSVP.h>

I hope this is what you need.

Okay, that was clear! It looks like you are trying to compile the .c file directly somehow instead of loading the project (.aps) file. You can note that there are actually no errors about orangutan.h, just errors in the linking step because it is not being linked against our library. If you load the .aps file, does it work?

Please ignore this post.............

I just got a successful build and programmed the 3PI. I followed the instructions in 7. Using the Pololu AVR Library for your own projects. I didn't realize that there were library and linker changes required. I just want to thank you again. There's nothing like seeing a program work!!!!

[paul]

Hello,
You should not have to make any linker changes if you start AVR studio by double-clicking on the .aps (project) file. However, if you have it working now, I guess you don't have to worry about that!

Hi,

Same experience with you louisstraub. Anyway, a very usefull post.

I think section no 7 (esp setting the library and and linker) should goes somewhere in section 6? I could feel there are other newbies like me experiencing the same problem. Don't you think Paul?

Thanks for the suggestion. We will try to make this clearer!
