Give the exact error-message or even better the complete output created
during make which included the arguments to the compiler.

I do not own the EasyARM kit and just took a quick look into the
Examples-package. As far as I can see the examples for the EasyARM-Kit
are created with Realview, so they not compatible with the GNU-tools
(maybe with a GNU toolchain targeted for arm-eabi). Either by Realview
(included in Keil MDK-ARM, eval.-version available) or ask
MikroElectronika for the source-code which have been used to create the
objects, adapt it to the GNU arm-toolchain and compile yourself.

Realview linker, but this linker will not "understand" arm-elf(oabi)
objects and may not understand arm-eabi.

Object-Code (basically output of the compiler and input to the linker)

It's just a file-extension (could be .o) too. Not OS-related.

Thanks Thomas,

 I think You are right. My enviroment is not compatible with the
examples by MikroElectronika. I am using Windows XP and WinARM files to
compile.

 I´ve asked them about the sources code but until now I did not get
reply.

 I am trying to compile a Graphics example. I have the "Glcd.obj" file
to link. When I include it in my "makefile" a get the follow link
errors:

1) Using Glcd.obj directly. Without -l parameter.

< Examples/LPC2214/V100/Examples/GLCD/sh.exe"-2.04$ make

2) Now adding the -l parameter in Glcd.obj inside makefile.

3)And now without the Glcd.obj file ( *** Probably missing library ***)
