Hi Jens,
I am getting the same assembler error when using ARM GNU tools (Rev:
2.95.3-1).
arm-unknown-elf-gcc -c src\test.c -gdwarf-2 -mcpu=arm7tdmi -o Debug\Objects\test.o
Assembler messages: Error: Can't open for reading. : No such file or directory
Errors during build.
Can you tell me what I am doing wrong. Any info you can provide would be helpfull..
Thanks JPatel

is installed into the Cygwin dierectory with an InstallShield
installation
routine. So, I don't know with what options the arm-gcc was build.

comes when the program tries to open a file or directory named path>/unknown/ . Looks like there is an Environment
variable or
similar missing and when the program builds a path using that
variable the
following file access of course goes wrong. Unfortunately I have no
clue what
variable that might be. Is there a list anywhere of what environment
variables
gcc needs ?
