Different behaviour if creating library instead of using all sources in generate_firmware

[carlosgalvezp]

Hi,

I have CMake 3.5.1, Arduino 1.6.10, Ubuntu 16.04.

I have observed that the generated executable has different behaviour when I compile using the following two configurations in the CMakelists:

A) Plug all the .cpp files into the generare_arduino_firmware function:

generate_arduino_firmware(${CMAKE_PROJECT_NAME}
      SRCS  loop.cpp ${MY_LIB_SRCS}
)

B) Create a library and link to it later:

generate_arduino_library(my_lib SRCS  ${MY_LIB_SRCS})
generate_arduino_firmware(${CMAKE_PROJECT_NAME}
      SRCS  loop.cpp 
      LIBS my_lib
)

Option A) produces the desired behaviours, whereas B) produces a slightly smaller executable and it does not work as expected (Arduino restarts over and over).

Why is this happening? How can it be fixed?

Thanks!
