I ran across this post while trying to find a solution to
the same problem. I thought I would add my 2-cents worth
for the archives. The original post was 2 months ago.
Maarten is correct. Here are the details.
Change the following line in the Makefile in device/lib from:
TARGETS += models small-mcs51-stack-auto
to:
TARGETS += models model-mcs51-stack-auto
before running make (after configure). This will build
all of the regular standard libraries as well as the
reentrant (stack-auto) versions. A "make install" will create
small, medium and large library directories as well
as small-stack-auto, medium-stack-auto, and large-stack-auto
directories under lib/.
As Maarten notes, using stack-auto is not recommended due
to the small stack on the 8051. This option is necessary
for building FreeRTOS though. (The FreeRTOS port to the
8051 works around the small stack limitation by
copying the stack to external memory on a task switch.)
