make file problem

[adamS]

Hi everyone,

I creates my .h file in /opt/quantaser/include and the corresponding .c file in /opt/quantaser/lib，
then I build the .so file from .c file and .h file and modify the redpitaya makefile to include the new path,
but when I run make command,
I always get "undefined reference to..." message,


I tried replace .so with .a file but got the same result,
Does anyone know how to solve this problem?
Many thanks!

.h file:

Code: Select all

#include <stdio.h>

void test_print(int, char*);

.c file:

Code: Select all

#include "tt.h"
#include <stdio.h>

void test_print(int num, char* a)
{
	for(int i=0;i<num;i++)
	{
		printf("%s\n",a);
	}

};

make file:

Code: Select all

CFLAGS  = -g -std=gnu99 -Wall -Werror
CFLAGS += -I/opt/redpitaya/include -I/opt/quantaser/include 

LDFLAGS = -L/opt/redpitaya/lib -L/opt/quantaser/lib



LDLIBS = -lm -lpthread -lrp

SRCS=$(wildcard *.c)
OBJS=$(SRCS:.c=)

all: $(OBJS)

%.o: %.c
	$(CC) -c $(CFLAGS) $< -o $@

clean:
	$(RM) *.o
	$(RM) $(OBJS)
