Makefile -lm

[rcracer]

Short question:

Where exactly in this makefile do i have to add the -lm to link the math libary

Code: Select all

CC=ee-gcc
AS=ee-as
LD=ee-elf-ld


OBJ_DIR = obj
CFLAGS = -Wall -W -EL -G0 -O0 -mips3 -nostdlib -DPS2_EE 

C_SRC = g2.c demo1.c
S_SRC = crt0.s ps2_asm.s dma_asm.s gs_asm.s

C_OBJ = $(addprefix $(OBJ_DIR)/, $(C_SRC:.c=.o))
S_OBJ = $(addprefix $(OBJ_DIR)/, $(S_SRC:.s=.o))

demo1.elf: $(C_OBJ) $(S_OBJ)
	@echo "-------------------------------------------------"
	$(CC) $(CFLAGS) -Tlinkfile -o demo1.elf $(C_OBJ) $(S_OBJ) -Wl,-Map,demo1.map

$(OBJ_DIR)/%.o: %.c
	@echo "-------------------------------------------------"
	$&#40;CC&#41; -c $&#40;CFLAGS&#41; $< -o $@ 

$&#40;OBJ_DIR&#41;/%.o&#58; %.s
	@echo "-------------------------------------------------"
	$&#40;CC&#41; -xassembler-with-cpp -c $&#40;CFLAGS&#41; $< -o $@ 

clean&#58;
	rm -f $&#40;C_OBJ&#41; $&#40;S_OBJ&#41; *.map *.elf

thank you

my guess is that here:

Code: Select all

$(CC) $(CFLAGS) -Tlinkfile -o demo1.elf $(C_OBJ) $(S_OBJ) -Wl,-Map,demo1.map 

[rcracer]

i have tried each position and with this:

Code: Select all

$(CC) $(CFLAGS) -Tlinkfile -o demo1.elf $(C_OBJ) $(S_OBJ) -lm -Wl,-Map,demo1.map

it seems math is linked but new errors:

You should use the "sdk" makefile. An example is like the NeoCD emulator:
