问题
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 '\1' in program
./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?
回答1:
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.
