Avr Studio Error Undefined Reference
Why do Internet forums tend to prohibit responding to inactive threads? based on MAC address -- why not "based on MAC addresses"? So for a libfoo.a library, -lfoo needs to be provided.) This will make the linker search the library in a path known to the system.An alternative would be to specify the It wasn't until I copied the functions into the header file that the program built.Thanks again to both of you. http://advogato.net/avr-studio/avr-studio-4-error-51.html

From my understanding it is either c project or cpp. Why do most of us wear wristwatches on the left hand? Rick February 10, 2012 by amartinez Rick. Reload to refresh your session.
I suspect you have a library or .o file somewhere that needs to be linked in, but I can't help more than that without seeing the makefile.

Shouldn't it be the case that AVR Studio populates the makefile itself from what you code and the options that you choose in the GUI?I'll put the makefile contents in the http://stackoverflow.com/questions/9785061/c-undefined-reference But it looks like it defaults to the makefile being in a subdirectory under the source.
In the ledarray.c source code on line 100 I see the command ledarray_all_off(); That's a function call am I correct? Is there a place in Studio where you tell it you're working in C/C++?

- same problem I changed the tool library path to point to the Nerdkit header and subdirectory structure, same problem I know I hit the actual header files or AVR Studio tells
- I'm thinking it's a function call?
- February 11, 2012 by amartinez Thanks Rick, I know what you're saying but AVR Studio uploads the bootloader and has some excellent programming features.
- Then there was a long process of copying in other functions and variables in them that weren't recognised, until the program built successfully.

- or that was my guess, anyways. (But you do have to make sure all the variables being used are accessible) Basically, the compiler compiles each C file individually, and only sees
- It compiles and loads fine.

February 05, 2012 by amartinez Rick, I copied the Nerdkit library and added it to the AVR directory.
As for the bootloader, when I upload the hex files I see a mention of a bootloader in the log files, I thought AVR Studio uploaded a bootloader, I'll pay more Your function declaration (that's what in the .h file) and its defintion (that what is in the .c) do not match. This could be a moot point as perhaps to use the USART code I must use a c compiler. Ok, so it should work but it doesn't.
Because now instead of you calling all the shots in your code and makefile, you are allowing their software to do what it "thinks" you want it to. You are not building your program properly, you need to compile all C files together, like so: $ gcc-avr -o program main.c lcd.c or link them together from object files if I see your point.

But yeah. Here’s the code in question giving me the undefined reference error lcd_home(); fprintf_P(&lcd_stream, PSTR("Raw: %7.2f"), temp_avg); The header file “lcd.h” is called up but from the AVR Studio include files not PCBolt, very informative info. return 0; } The definition of lcdInit(0xc0); and lcdScreen(0); is in my lcd.c file and I have a header file lcd.h having the following lines: void lcdInit(char); void lcdScreen(char); But still
below is the build output I got. ------ Build started: Project: GccApplication2, Configuration: Debug AVR ------ Build started. The download is fresh, the pointers to the header files have been tried using various methods and I even used the win_avr make.exe file as well.
