You need to link against the SDCC/pic14 device libraries as SDCC does as well: sdcc -mpic14 -p16f627 main.c -V tells you that sdcc links using gplink -w -r -o main main.o libsdcc.lib pic16f627.lib -w suppresses your warning (processor mismatch), -r allows to use shared banks (suppresses errors like no memory found for section foo_bar), libsdcc.lib provides helper routines for the backend (char/int/long arithmetics, pointer dereferencing, ...) and lib16f627 provides definitions for the SFRs (PORTA in your case). BTW: You might also try sdcc -mpic14 -p16f627 main.c other.o another.o which should build and link your project correctly (use -V to verify the linker's arguments and their order).
