Question

我的Makefile一直告诉我

make: *** No rule to make target `rs232.c',

我在这里列出文件（rs232.c在最后） -

SOURCES_RAW=codeprofiler.cpp gametimer.cpp timer.cpp timeprofile.cpp vector4.cpp matrix.cpp agent.cpp agentcontroller.cpp dummy.cpp evader.cpp pursuer.cpp goal.cpp player.cpp graphdata.cpp graph.cpp cubiccoefs.cpp segment.cpp trajectory.cpp anode.cpp arrayvector4.cpp color.cpp drawcomponent.cpp drawcontroller.cpp flags.cpp global.cpp map_analyzer.cpp minheap.cpp node.cpp quadtree.cpp queue.cpp results.cpp sensor.cpp settings.cpp utility.cpp world.cpp gui.cpp main.cpp logger.cpp parameters.cpp counter.cpp polygon.cpp line.cpp robot_driver_agent.cpp position.cpp robot_driver_priorityqueue.cpp main.cpp robot_driver_tree.cpp robot_driver_grid.cpp path.cpp tcpserver.cpp tcpclient.cpp servercontrol.cpp clientcontrol.cpp Robot.cpp udpserver.cpp udpclient.cpp rs232.c

所有文件都在名为src的文件夹中。所以我做 -

SRCDIR= src
SOURCES:=$(SOURCES_RAW)
SOURCES:=$(patsubst %.c, $(SRCDIR)/%.c, $(SOURCES))
SOURCES:=$(patsubst %.cpp, $(SRCDIR)/%.cpp, $(SOURCES))

为什么不编译.c文件？

整个Makefile是 -

以前的所有文件（rs232.c之前）实际上都是C ++文件。

我猜你有一个规则来编译C ++文件，稍后在你的makefile中，但你是否也有编译纯C文件的规则？

像：

%.o: %.c
    gcc [...]

编辑 - 只是为了让您知道

您不必强制指定要编译的所有文件。

查看foreach和dir功能这样，您就可以从目录中获取与特定模式匹配的所有文件。

示例：

FILES = $(foreach dir,$(DIR_SRC),$(wildcard $(DIR_SRC)*.cpp))

使用.cpp和.c？
