Another approach is to simply put your config in a separate C file and then just link that in. Keeps your source a little more readable. Indeed, you can even link in an asm file with nothing but the fuses. (IMO, the ASM is more readable in this case.)

I've already solved this problem. So I'll explain how to. I'm using Piklab IDE on Ubuntu 8.10 and ICD 2 Programmer - works well. The problem was on the fuses configuration. When we build a project on Piklab using Small Device C Compiler there's no fuses configuration generated - fuses are default configured. So I found a way in Piklab to do that, goes likes this: Select Tools > Config Generator... This will open a "Config Generator" window where we can select the desired device and configure its fuses. After that we can select "Copy to Clipboard" button and paste the fuses configuration in the C code file (after includes). For the exampled I've listed before, my chosen fuses for PIC18F4550 on the referred window generated the follow code: code char at __CONFIG1L CONFIG1L = _PLLDIV_NO_DIVIDE__4MHZ_INPUT__1L & _CPUDIV__OSC1_OSC2_SRC___1__96MHZ_PLL_SRC___2__1L & _USBPLL_CLOCK_SRC_FROM_OSC1_OSC2_1L; code char at __CONFIG1H CONFIG1H = _OSC_XT__USB_XT_1H & _FCMEN_OFF_1H & _IESO_ON_1H; code char at __CONFIG2L CONFIG2L = _PUT_OFF_2L & _BODEN_OFF_2L & _BODENV_2_0V_2L & _VREGEN_OFF_2L; code char at __CONFIG2H CONFIG2H = _WDT_DISABLED_CONTROLLED_2H & _WDTPS_1_32768_2H; code char at __CONFIG3H CONFIG3H = _CCP2MUX_RC1_3H & _PBADEN_PORTB_4_0__CONFIGURED_AS_ANALOG_INPUTS_ON_RESET_3H & _LPT1OSC_OFF_3H & _MCLRE_MCLR_ON_RE3_OFF_3H; code char at __CONFIG4L CONFIG4L = _STVR_OFF_4L & _LVP_OFF_4L & _ENICPORT_OFF_4L & _ENHCPU_OFF_4L & _BACKBUG_OFF_4L; code char at __CONFIG5L CONFIG5L = _CP_0_OFF_5L & _CP_1_OFF_5L & _CP_2_OFF_5L & _CP_3_OFF_5L; code char at __CONFIG5H CONFIG5H = _CPB_OFF_5H; code char at __CONFIG6L CONFIG6L = _WRT_0_OFF_6L & _WRT_1_OFF_6L & _WRT_2_OFF_6L & _WRT_3_OFF_6L; code char at __CONFIG6H CONFIG6H = _WRTC_OFF_6H & _WRTB_OFF_6H; code char at __CONFIG7L CONFIG7L = _EBTR_0_OFF_7L & _EBTR_1_OFF_7L & _EBTR_2_OFF_7L & _EBTR_3_OFF_7L; code char at __CONFIG7H CONFIG7H = _EBTRB_OFF_7H; Now the LED is blinking ;) There is a remaining fault -> it takes over 20 seconds to start blinking. Thanks for everything.
