Hello,
While trying to compile very simple project (hello_world) the following errors occur (please see the copy of Build log below)
Can someone help me in resolving of the problem.
Or at least understand what mean these messages - in the core of error message there is "selected processor" ... but in compiler settings I didn't specify any processor ?
Hi,
What default cpu is the compiler configured with? Look for the
--with-cpu or --with-arch line in the output of 'gcc -v'. Judging from
the 'cc2538dk' in your path I'm guessing you're trying to build for a
Cortex-M3 processor? Try specifying -mthumb and -mcpu=cortex-m3 on the
command line explicitly.
Kyrill
Thanks in advance.
