RE: Link error for arm-elf under Cygwin

[Amit <amit at connectone dot com>]

Grant Thanks !
That did solve my link problem.
However a new one cropped up, which may be connected.
I failed to mention that I am using newlib.
The previous link used libc.a at: D:\cygwin\home\amit\arm-elf\arm-elf\lib\
I found libgcc at: D:\cygwin\home\amit\arm-elf\lib\gcc-lib\arm-elf\2.95.3\

Now linking with:
$ arm-elf-ld -e0x8000 -o test test.o -lc -lgcc

I tried debugging with Insight 5.1 and received the following error on the
malloc() line:
 str=(char *)malloc(80)

$ arm-elf-gdb -nw test
