GPUTILS is described as 'Gputils is a collection of development tools for Microchip (TM) PIC (TM) microcontrollers. It's intended to be compatible with the manufacturer's tools, MPASM, MPLINK and MPLIB' and is a Compiler in the development category. There are three alternatives to GPUTILS for Linux, Mac, Windows and Eclipse. The best GPUTILS alternative is SDCC - Small Device C Compiler, which is both free and Open Source. Other great apps like GPUTILS are CPIK and PicCBuilder.
SDCC is a retargettable, optimizing Standard C (ANSI C89, ISO C99, ISO C11) compiler suite that targets the Intel MCS51 based microprocessors (8031, 8032, 8051, 8052, etc.), Maxim (formerly Dallas) DS80C390 variants, Freescale (formerly Motorola) HC08 based (hc08, s08), Zilog...
The PicCBuilder is an Eclipse plugin for allowing the use of Eclipse CDT as the editor and builder of projects for Microchip PIC microcontrollers. It creates makefiles that involke the C30 or C32 toolchain to generate the binary files.
