The experimental Debian repositories do not include msp340-libc, because we
are still cleaning up copyright issues. So it's really not yet ready for
use, unless you don't need libc functionality, or you build the pieces
yourself.
You should not have needed to add the -L path, but you may not have provided
the right -mmcu option at the link phase: without it, the gcc driver can't
figure out what path to add. Don't use msp430x2553: use the real target MCU
identifier (msp430g2553). Especially in the value-line family, there are
differences in layout between the F and G variants and the genericized
version doesn't work.
The syntactic sugar provided by signal.h was removed in uniarch following
previous discussions over the last year.

Simplify data backup and recovery for your virtual environment with vRanger.
Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
Nope - It's vRanger. Get your free trial download today.
