Makefile compile error - c

Question

I have an makefile but doesn't work. The error in terminal is this: cc -shared -o build/liblcthw.so src/lcthw/list.o
/usr/bin/ld: src/lcthw/list.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
src/lcthw/list.o: error adding symbols: Bad value
I need help to put the gcc comand gcc -shared -o target.so -fPIC target.c, i don't how to put the target.c instead list.o
This is the makefile:
CFLAGS=-g -O2 -Wall -Wextra -Isrc -rdynamic -DNDEBUG $(OPTFLAGS)
LIBS=-ldl $(OPTLIBS)
PREFIX?=/usr/local
SOURCES=$(wildcard src/**/*.c src/*.c)
OBJECTS=$(patsubst %.c,%.o,$(SOURCES))
TEST_SRC=$(wildcard tests/*_tests.c)
TESTS=$(patsubst %.c,%,$(TEST_SRC))
TARGET=build/liblcthw.a
SO_TARGET=$(patsubst %.a,%.so,$(TARGET))
# The Target Build
all: $(TARGET) $(SO_TARGET) tests
dev: CFLAGS=-g -Wall -Isrc -Wall -Wextra $(OPTFLAGS)
dev: all
$(TARGET): CFLAGS += -fPIC
$(TARGET): build $(OBJECTS)
ar rcs $# $(OBJECTS)
ranlib $#
$(SO_TARGET): $(TARGET) $(OBJECTS)
$(CC) -shared -o $# $(OBJECTS)
build:
#mkdir -p build
#mkdir -p bin
# The Unit Tests
.PHONY: tests
tests: CFLAGS += $(TARGET)
tests: $(TESTS)
sh ./tests/runtests.sh
valgrind:
VALGRIND="valgrind --log-file=/tmp/valgrind-%p.log" $(MAKE)
# The Cleaner
clean:
rm -rf build $(OBJECTS) $(TESTS)
rm -f tests/tests.log
find . -name "*.gc*" -exec rm {} \;
rm -rf `find . -name "*.dSYM" -print`
# The Install
install: all
install -d $(DESTDIR)/$(PREFIX)/lib/
install $(TARGET) $(DESTDIR)/$(PREFIX)/lib/
# The Checker
BADFUNCS='[^_.>a-zA-Z0-9](str(n?cpy|n?cat|xfrm|n?dup|str|pbrk|tok|_)|stpn?cpy|a?sn?printf|byte_)'
check:
#echo Files with potentially dangerous functions.
#egrep $(BADFUNCS) $(SOURCES) || true

Your objects for liblcthw.a are built with -fPIC. Objects for liblcthw.so are not built with this setting.
Try changing rule:
$(SO_TARGET): $(TARGET) $(OBJECTS)
$(CC) -shared -o $# $(OBJECTS)
to:
$(SO_TARGET): $(TARGET)
$(CC) -shared -o $# $^
Since the required objects are already in liblcthw.a.
Or, alternatively:
$(SO_TARGET): CFLAGS += -fPIC
$(SO_TARGET): $(OBJECTS)
$(CC) -shared -o $# $(OBJECTS)
