Hi,
In order to track the SDCC source code by using GDB, thus I want to
recompile the SDCC source code without optimization.
There comes the question,when I make the source with the command:make
CFLAGS='-g -gstabs',the terminal print out some uncertain errors,such as
../../../sdcc/debugger/mcs51/simi.c: In function ‘openSimulator’:
../../../sdcc/debugger/mcs51/simi.c:382: error: ‘FNONBLOCK’
undeclared (first use in this function)
../../../sdcc/debugger/mcs51/simi.c:382: error: (Each undeclared
identifier is reported only once
../../../sdcc/debugger/mcs51/simi.c:382: error: for each function
it appears in.)
In file included from
../../../sdcc/support/cpp/libcpp/include/symtab.h:25,
from
../../../sdcc/support/cpp/libcpp/include/cpplib.h:28,
from ../../../sdcc/support/cpp/sdcpp.h:162,
from ../../../sdcc/support/cpp/system.h:848,
from ../../../sdcc/support/cpp/sdcpp.c:26:
../../../sdcc/support/cpp/libiberty/obstack.h:153:40: error: attempt to use
poisoned "bcopy"
I test the command:make CFLAGS,it work fine.
I just want to track the source code.
solutions?
Thanks
