Hi,
When i try to compile the newlib-lpc (make all) output window says next:

> "make.exe" all

and when i compile the (make lib), output windows says next:

And then i copy the libnewlib-lpc.a file to the project where the linker
searches libraries and try to use sprintf function and output windows
show next:

from where you try to build this ? natively or under cygwin ?

what is you version of make.exe ?

does this directory exist ? /usr/lib/gcc/arm-elf/4.1.1 ?

I have never rebuild it but it seem to ba a pth related problem.

So something just failed here. As Jonathan Dumaresq already mentioned
this looks like a problem with the shell (bash!=cmd) or a tool called by
make.

The libnewlib-lpc.a which the linker tries to link does not support
interwork.

First create a newlib-lpc with interwork-support and try again.
newlib-lpc provides the isatty function IRC.

> can you say what is going wrong?

You build your application with thumb/thumb-iw and try to link a library
which does not support this.

I have done an experimental makefile for newlib-lpc:
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/winarmtests/Makefile_newlib_lpc_interwork.txt

This should create a newlib-lpc with thumb/thumb-iw support in file
libnewlib-lpc_IW.a. So change your project's makefile to use this
library (add the "_IW" maybe you have to extend the
library-search-path). So far I have not tested with hardware or a
simulator. So just give it a try and write what you have found out.

please?

newlib-lpc on an AT91SAM7X? Strange idea. At least the UART-drivers and
the functions to set up MAM/VPB etc. in the newlib-lpc (-lpc not
"-sam7") will not work for SAM7s.

Provide you own isatty-function.

Provide the device_table. It's an array of device_table_entry structs.
See the newlib-lpc examples.

Thanks a lot Martin. I was very confused with the whole library. So this
is not a library to work with AT91SAM7X! I'm very new to this, so please
don't laugh! Do you know any library that I could use with this
hardware?

Thanks,
Tudor
