这是我们当前的Makefile;我们试图运行的测试文件包括“phase1.h”。
TARGET = libphase1.a
CFLAGS = -Wall -g
TESTDIR = ./tests
TESTS = forkInvalidParmsTest
LIBS = -lphase1 -lusloss
$(TARGET): phase1.c
ar -r $@ phase1.c
$(TESTS): $(TARGET) $(TESTDIR)/$@
gcc $(CFLAGS) -c -I./usloss/build/include $(TARGET) $(TESTDIR)/$@.c
gcc $(LDFLAGS) -o forkInvalidParmsTest forkInvalidParmsTest.o $(LIBS) ./usloss/lib/linux/libusloss2.8.a
这是我们在尝试运行make forkInvalidParmsTest（成功生成libphase1.a之后）收到的错误。
gcc -Wall -g -c -I./usloss/build/include libphase1.a ./tests/forkInvalidParmsTest.c
./tests/forkInvalidParmsTest.c:2:20: fatal error: phase1.h: No such file or directory
#include "phase1.h"
有什么想法吗？
更新
自添加-I后错误已更改。对cflags：
make forkInvalidParmsTest 2 ↵ ✖ ✹master
gcc -Wall -g -I. -c -I./usloss/build/include libphase1.a ./tests/forkInvalidParmsTest.c
gcc: warning: libphase1.a: linker input file unused because linking not done
gcc -o forkInvalidParmsTest forkInvalidParmsTest.o -lphase1 -lusloss ./usloss/lib/linux/libusloss2.8.a
/usr/bin/ld: cannot find -lphase1
/usr/bin/ld: cannot find -lusloss
collect2: error: ld returned 1 exit status
make: *** [forkInvalidParmsTest] Error 1

我与你分享了我的示例makefile（我无法在comment部分输入所有内容，如果没有回答你的问题，请告诉我们）：
这是我的文件夹视图：

Makefile1，没有生成lib

然后，我设置了另一个文件夹结构（简单，删除一些文件），这次我生成了lib：
./

Makefile2.1，top makefile：

#
在每个模块中，我都有单独的mk文件，生成了自己的lib：
#you just need change this MODULE name
MODULE = debug
LIB = $(LIB_DIR)/lib$(MODULE).a
SRCS = $(wildcard *.c)
OBJS = $(patsubst %.c, %.o, $(SRCS))
DEPS = $(patsubst %.c, %.d, $(SRCS))
$(LIB): $(OBJS)
@mkdir -p ../libs
@$(AR) cr $@ $^
@echo " Archive $(notdir $@)"
#$(OBJS): $(SRCS)
%.o: %.c
@$(CC) $(CFLAGS) -o $@ -c $<
@echo " CC $@"
# Automatic dependency magic:
#%.d: %.c
# $(CC) -MM $(CFLAGS) $@ > $<
#-include (SRCS:%.c=%.d)
.PHONY: clean
