FIXED — StellarPad Linking Error #122

When building and linking a medium sized project, I have this error message from Energia at the linking stage:

mySketch.cpp.o: In function __static_initialization_and_destruction_0': mySketch.cpp:88: undefined reference to__dso_handle' /Applications/Energia.app/Contents/Resources/Java/hardware/tools/lm4f/bin/../lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/lib/thumb/armv7e-m/fpu/fpv4-sp-d16/libc.a(lib_a-sbrkr.o): In function _sbrk_r': /Users/rwessels/yagarto/newlib-build/arm-none-eabi/thumb/armv7e-m/fpu/fpv4-sp-d16/newlib/libc/reent/../../../../../../../../../newlib-1.20.0/newlib/libc/reent/sbrkr.c:58: undefined reference to_sbrk' /Applications/Energia.app/Contents/Resources/Java/hardware/tools/lm4f/bin/../lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/bin/ld: mySketch.cpp.elf: hidden symbol `__dso_handle' isn't defined /Applications/Energia.app/Contents/Resources/Java/hardware/tools/lm4f/bin/../lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status

This is because _sbrk() hasn't been implemented yet. It is used by newlib to allocate memory on the heap. I'm looking at the best way to implement both the stack and the heap. If you use malloc or new those calls will not work until this code is implemented. It might be premature to be filing bugs on something that hasn't even been tested or released from development.

Ok. Thanks.

please check commits, this might fix your problem:

https://github.com/energia/Energia/commit/32236716e4493b9154041d9ceaed4997c8417d27

Please give it a try.

Thanks. _sbrk() seems to be fixed but I'm still having the __dso_handle error.

RickKimball commented 11 years ago

Where can I find the program source you are testing?

rei-vilo commented 11 years ago

The program is GUI_main.pde using the Serial_LCD library.

This program is used as a test protocol for Arduino-like IDEs. Presently, it works with Arduino 23 and 1.0, chipKIT MPIDE and Wiring.
