Andrew thank you for your reply. I suspected that too but after changing GFXLIB to static (GFXLIB = C:\ChibiStudio\ugfx) I take same error to the next level of using this definition: from make file: # Imported source files and paths CHIBIOS = ../../chibios GFXLIB = C:\ChibiStudio\ugfx include $(CHIBIOS)/boards/HANC3_EVAL/board.mk include $(CHIBIOS)/os/hal/platforms/STM32F1xx/platform.mk include $(CHIBIOS)/os/hal/hal.mk include $(CHIBIOS)/os/ports/GCC/ARMCMx/STM32F1xx/port.mk include $(CHIBIOS)/os/kernel/kernel.mk include C:\ChibiStudio\ugfx\gfx.mk (moved to hardcode solution also) (Errors: 14 Items) make: /src/gos/sys_make.mk: No such file or directory Olimex-STM32-LCD line 4, external location: C:\ChibiStudio\ugfx\gfx.mk C/C++ Problem C:/ChibiStudio/ugfx: Permission denied Olimex-STM32-LCD line 5, external location: C:\ChibiStudio\ugfx\gfx.mk C/C++ Problem make: /src/gdriver/sys_make.mk: No such file or directory Olimex-STM32-LCD line 5, external location: C:\ChibiStudio\ugfx\gfx.mk C/C++ Problem C:/ChibiStudio/ugfx: Permission denied Olimex-STM32-LCD line 6, external location: C:\ChibiStudio\ugfx\gfx.mk C/C++ Problem ... .... ...... ....... make: *** No rule to make target `/src/gfile/sys_make.mk'. Stop. Olimex-STM32-LCD C/C++ Problem As a result seems to need hard-coding every path uses GFXLIB. Is there any clue how to fix this? I also try to build this makefile using cmd.exe make -j4 without any luck. I'm using Windows-7 Pro and ChibiStudio without changing anything from the zip I extracted it.
