Question

我的Makefile有一个非常令人困惑的问题

我正在使用它为linux和windows

构建一个带有条件编译的单元测试可执行文件

对于从src代码构建目标文件的规则，它缺少某些文件。似乎没有一个模式，例如所有丢失的文件来自特定目录 - 它似乎随机发出一些我的src文件。

我的Makefile看起来像这样：

TARGET := test_glamdring2
program_NAME := $(TARGET)

#WIN32 - need to install hg on WIN32 platform for this line to work
#HGVERSION:= $(shell hg parents --template 'hgid: {node|short}')

# Platform specific conditional compilation
UNAME := $(shell uname)

# specify dirs other then current dir to search for src files
VPATH = ../src ../../RESTRICTED/core/src ../../RESTRICTED/pulse_IO/src

# src code file locations realtive to test/ dir
# SRCS =  main.c \
#   test_utility.c \

请注意，minIni.c, ddi.c, mem.c, pulseIO.c, lib.c and bsd_offset.c未编译到其repsective对象文件

中

我已经检查过src代码文件实际存在于相关目录中，因此我必须在Makefile中做错了但是我无法发现它是什么......

更新

更改了这一行：

$(BUILD_DIR)/%.o: %.c

有：

$(program_OBJS): $(program_C_SRCS)

这会引入所有* .o文件但在每个实例中使用main.c，即输出看起来像这样：

Answer 1

如果输入文件比输出文件旧，则make将不会构建它。因此make不会在构建之间编译未经编译的C文件。这加快了编译速度。

尝试以下方法：

make clean all

在Makefile中缺少src代码文件
