I deleted library folder paths and name because I shouldn’t publish those names. If I put syscalls.c on build path I get this:

src/syscalls.o: In function `initialise_monitor_handles’:
D:.../src/syscalls.c:72: multiple definition of `initialise_monitor_handles’
c:/ac6/systemworkbench/plugins/fr.ac6.mcu.externaltools.arm-none.win32_1.7.0.201602121829/tools/compiler/bin/../lib/gcc/arm-none-eabi/5.2.1/../../../../arm-none-eabi/lib/armv7e-m/fpu\librdimon_nano.a(rdimon-syscalls.o):syscalls.c:(.text.initialise_monitor_handles+0x0): first defined here

and then repeated for every function in syscalls.c, followed by undefined reference to `initialise_monitor_handles()’ in main.cpp
