Git打破了我的程序？ [英] Git breaks my program?

问题描述

我有几个程序，我在一个主分支下编写，我使用GNUmakefile编译。今天，在我创建了一个新的分支，v4.3，并切换到新的分支，然后编译之后，我得到以下错误消息：

  lucerne：lucerne $ make primes 
 g ++  -  mp-4.8 -std = gnu ++ 0x -g -O2 -W -Wall -Wextra -MD -MF .deps / primes.d -MP -一世。 -c -o primes.o primes.cpp 
在从primes.cpp：2：0包含的文件中：
 ./vector:1:1：error：stray'\317'in program 
 ???? _ TEXT 
 ^ 
 ./vector:1:1：error：stray'\372'in program 
 ./vector:1:1：error：stray' \355'in program 
 ./vector:1:1：error：stray'\376'in program 
 ./vector:1:1：error：stray'\7'in program 
 ./vector:1:6：warning：null字符被忽略[默认启用] 
 ./vector:1:1：错误：程序中的stray'\1'
 ./vector:1:1：error：stray'\3'in program 
 ./vector:1:10：warning：null字符被忽略[默认启用] 
 ./ vector：1：1：error：stray'\200'in program 
  

消息，当我切换到主分支。但是，如果我将文件重命名为其他名称，如new_primes.cpp，则 make file 不会导致任何问题。 GNUmakefile或prime.cpp都没有被修改。我也没有安装任何额外的包。它也不是编辑 - 我使用emacs和TextWrangler。是什么原因导致这个问题？

解决方案

当源文件（在这种情况下，包含文件）是二进制文件时，会生成GCC错误。这很容易通过创建具有单个包含到二进制文件/ bin / ls的源文件来重现。创建stray.c与：

  #include/ bin / ls
  / pre> 
 
 
快速完成：
  gcc -c stray。 c 
  
产生以下输出：
 在stray.c：1：0包含的文件中：
 / bin / ls：1：1：error：stray'\177'in program 
 / bin / ls：1：1：错误：程序中的stray'\2'
 / bin / ls：1：1：错误：程序中的stray'\1'
 / bin / ls：1 ：1：错误：程序中的stray'\1'
 / bin / ls：1：8：警告：忽略空字符[默认启用] 
 / bin / ls： 1：错误：程序中的stray'\2'
 / bin / ls：1：18：warning：null字符被忽略[默认启用] 
  / pre> 
 
 
看来'vector'是一个二进制文件。
 
 
 
有两种可能的原因
 
 
 C ++'vector'头文件已损坏。
 
 
矢量。
 
 
我猜它的第二个。检查并确保在编译器包含路径中没有二进制称为向量。
 
I have several programs that I have been writing under a master branch, which I compile using GNUmakefile. Today, right after I created a new branch, v4.3, and switched onto the new branch, and then compile, I get the following error message: 
lucerne:lucerne$ make primes
g++-mp-4.8 -std=gnu++0x -g -O2 -W -Wall -Wextra  -MD -MF .deps/primes.d -MP  -I. -c -o primes.o primes.cpp
In file included from primes.cpp:2:0:
./vector:1:1: error: stray '\317' in program
 ????_TEXT

./vector:1:1: error: stray '\372' in program
./vector:1:1: error: stray '\355' in program
./vector:1:1: error: stray '\376' in program
./vector:1:1: error: stray '\7' in program
./vector:1:6: warning: null character(s) ignored [enabled by default]

./vector:1:1: error: stray '\3' in program
./vector:1:10: warning: null character(s) ignored [enabled by default]
./vector:1:1: error: stray '\200' in program
I get the same error message when I switch to master branch. However, if I rename the file to something else, like "new_primes.cpp", then make file does not cause any problem. Neither GNUmakefile or prime.cpp has been modified. I also have not installed any additional packages. It is also not the editor - I am using emacs and TextWrangler. What is causing this problem?  
解决方案
The error generated by GCC occurs when the source file, or in this case, included file is a binary file.  This is easily reproduced by creating a source file with a single include to a binary file, /bin/ls for example.  Create stray.c with:
#include "/bin/ls"
A quick complie:
gcc -c stray.c
Yields the following output:
In file included from stray.c:1:0:
/bin/ls:1:1: error: stray '\177' in program
/bin/ls:1:1: error: stray '\2' in program
/bin/ls:1:1: error: stray '\1' in program
/bin/ls:1:1: error: stray '\1' in program
/bin/ls:1:8: warning: null character(s) ignored [enabled by default]
/bin/ls:1:1: error: stray '\2' in program
/bin/ls:1:18: warning: null character(s) ignored [enabled by default]
It appears that 'vector' is a binary file.

There are two possible causes that come to mind:

The C++ 'vector' header file is corrupt.
There is another 'vector' in your search path.
I'm guessing its the second.  Check and make sure you don't have a binary called vector within the compiler include path.
