"undefined reference to memcpy" error - please help!

please post the c-code

>please post the c-code
Why? This is a linker error.

Did you include string.h or memory.h?
I am not familiar with your IDE, but memcpy() usually requires one of 
these include files.

hello

as you can see in the attachment
if I include any of standart library header files

it gives "unresolved inclusion" error

besides the original "undefined reference" error is still there
if I build again

Hey,

im using the same IDE with YAGARTO-Toolchain. I had the same problems 
few days ago.
Do you have this 4 path in your project? Otherwise the compiler wont 
find your included files.

Ahh... Sry for double pictures...

>if I include any of standart library header files

Well, simply not putting it in is probably not the right solution.

All these effects point into the direction of a incomplete or defect 
installation of the tool chain. Apparently the compiler is missing the 
system include dir paths, and the linker is missing the system lib path.

Is there a specific reason why you call target-ld by hand and don't use 
the driver target-gcc for linking?

If you call it by hand you will have to set all the options by hand that 
the driver would set for you...

I totally agree

however this IDE I downloaded from Olimex
the name of this package is OlimexODS

the package sucessfully installed
only I had to install Java seperately

and I had to adjust the PATH variable of my windows XP
to point to ...yagarto\bin

Would all of you PLEASE stop talking all your include file nonsense?

This is a linker error, include files have NOTHING to do with it. The 
linker doesn't find thee libraries. Libraries, not headers!

hello I took your advice

however this time it gives error about map file

1

c:/olimexods/yagarto/bin/../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/bin/ld.exe:./main.map: file format not recognized; treating as linker script

2

c:/olimexods/yagarto/bin/../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/bin/ld.exe:./main.map:2: syntax error

3

collect2: ld returned 1 exit status

4

make: *** [main.out] Error 1

if I comment this out in linker command line
>-Map main.map
it compiles

I have some questions ;
1) is this map file important ?
2) if I link with gcc instead of ld , will the code be stable ?
will it link with latest version of library ?

thanks

> if I link with gcc instead of ld , will the code be stable ?

Your trials with using ld directly did not produce any usable code at 
all.

The program "gcc" itself is neither a compiler nor a linker. It is the 
standard interface to all elements of the tool chain (compiler, linker, 
assembler, ...), and calls all of them, using the right paprameters.

Therefore using gcc is the most appropriate option.

hello forum,

I squeezed the error down to above message after I changed the
...ld to ...gcc

I searched the forum for past messages
some people faced the same error like me
but I didnot understand anything

what is this _sbrk?
how can I get rid of it ?

thanks

hello thanks for the answer but

I have no operating system
this is a standalone application

on an ARM Cortex M4 microcontroller

thank you, how can I proceed ?

or read the documentation of newlib. google will give you also some more 
info on that issue.
