I don't think override CFLAGS means anything. Maybe try taking all of this out of Makefile.am and giving this information on the configure command-line: ./configure CC=sdcc LD=sdcc CFLAGS='--use-non-free -mpic16 -p18f4550' and so on. > I need to compile the code using SDCC compiler with the flags i specified > there, > but when i try `make` i got error because of additional flags being added that > SDCC doesn't recognize: Right, I reckon the configure script isn't seeing what you put in Makefile.am, finds another C compiler and is using flags appropriate for that compiler. Putting CC=sdcc on the command line will let it know. (I believe the error message you're getting is to do with the "dependency style" of the C compiler that was found.)
