.Tpo 文件是如何生成的？为什么有“没有这样的文件或目录”？

Question

make的输出：

Making all in access/
gcc  -g -O2   -o fileOpt fileOpt.o  
Making all in executor/
gcc  -g -O2   -o executor execFilter.o execJoin.o execMain.o execNode.o execProject.o execScan.o execSort.o execUtil.o  
Making all in index/
gcc  -g -O2   -o index b_plus_tree.o  
Making all in nodes/
gcc  -g -O2   -o nodes nodes.o  
Making all in optimizer/
gcc  -g -O2   -o optimizer optimizer.o path.o  
Making all in parse/
gcc  -g -O2   -o parser analyze.o check.o gram.o parser.o scan.o  
Making all in posql/
gcc -DHAVE_CONFIG_H -D_GNU_SOURCE -I. -I.. -I /Users/YOuth/Program/posql/src/backend/include     -g -O2 -MT ../util/transfrom.o -MD -MP -MF .deps/../util/transfrom.Tpo -c -o ../util/transfrom.o ../util/transfrom.c
error: error opening '.deps/../util/transfrom.Tpo': Error opening output file '.deps/../util/transfrom.Tpo': No such file or director

我在其他文件夹（访问/索引/ ...）中找到，它在.dep文件夹中也没有.Tpo文件？为什么它只是 util 找不到？

ls util/
Makefile    Makefile.am Makefile.in transfrom.c util.c

transfrom.c:

#include "util/transfrom.h"
#include "util/datatype.h"
#include "string.h"
#include "stdlib.h"

void strToDate(Date* date , char* str){
    ....
}

我的问题是Tpo 是如何生成的？是否有任何可能甚至明显的错误？提前致谢。

Answer 1

在列出的 makefile 的其他问题中，这个参数：.deps/../util/transfrom.Tpo 不太可能是正确的。

它说：在子目录.deps（注意.） 上一级目录（即 makefile 所在的位置），然后下一级到 util 目录。

然后生成文件transfrom.Tpo。

嗯。也许这只是一个错字，但我怀疑transform.Tpo 是错误的，正如所呈现的路径一样。

然而，有趣的是（通常）每个源文件都有一个依赖文件，而不仅仅是一个依赖文件。通常最好将这些依赖文件命名为与关联源文件相同的根名称，并具有唯一的扩展名，例如.d

我建议在单独的 make 文件规则中生成依赖文件，使用 -M -MF <file name>.c

不要使用-MP，因为这会导致gcc 为每个文件生成一个目标并且不提供任何依赖项。

gcc 参数详情可在以下位置找到： http://tigcc.ticalc.org/doc/comopts.html#SEC3

下面是一个make文件（实际上是一对makefile），它处理 在每个子目录和主目录中生成依赖、编译、链接。他们使用sed 而不是gcc 来生成依赖文件，但上述信息将使您能够调整该规则。

这是顶级生成文件： 注意：allDirectories 宏是子目录的列表， 这将不得不调整您的子目录列表
