私はmakefileに精通していません、これが私のmakefileです
CC = gcc
TARGET = sample_client sample_server
CFLAGS += -g -I/usr/include
LDFLAGS += -g -lprotobuf-c -L/usr/lib
all: $(TARGET)
$(TARGET): lsp.o lspmessage.pb-c.o
%.o: %.c
$(CC) -c $(CFLAGS) $< -o $@
clean:
rm -f *.o
rm -f $(TARGET)
make -f Makeを実行すると、これらのエラーが発生します。
**@**:./$ make -f Makefile
