clang ++链接失败:错误:源文件无效的UTF-8? [英] clang++ link failure: error: source file is not valid UTF-8?
问题描述
我遇到一个有趣的问题.我正在用
I'm having an interesting problem. I'm compiling a toy compiler with
clang++ -g -x c++ y.tab.c lex.yy.c semantic_actions.cpp -o parser -lfl
在y.tab.c
中,我包含了semantic_actios.hpp
,而semantic_actions.hpp
中的内容是y.tab.c
中使用的一些方法声明.这样编译就可以了.
In y.tab.c
I included semantic_actios.hpp
and the contents in semantic_actions.hpp
are some method declarations that are used in y.tab.c
. That compiles fine.
但是,如果我将其更改为
However if I change it to
clang++ -c -g -x c++ semantic_actions.cpp -o semantic_actions.o
clang++ -g -x c++ y.tab.c lex.yy.c -o parser semantic_actions.o -lfl
我知道
semantic_actions.o:1:1: error: source file is not valid UTF-8
<CF><FA><ED><FE><U+0007>
^
semantic_actions.o:1:2: error: source file is not valid UTF-8
<CF><FA><ED><FE><U+0007>

semantic_actions.o:1:3: error: source file is not valid UTF-8

<CF><FA><ED><FE><U+0007>
^
semantic_actions.o:1:6: warning: null character ignored [-Wnull- character]
<CF><FA><ED><FE><U+0007>
// and the output goes on and on
我必须在这里错过一些非常基本的东西.我在Mac OS优胜美地
I must missed something very basic here. I'm on Mac OS Yosemite
$ clang++ --version
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.1.0
Thread model: posix
有人可以看看吗?谢谢!
Can someone have a look at it? Thanks!
推荐答案
clang++ -g -x c++ y.tab.c lex.yy.c -o parser semantic_actions.o -lfl
您要告诉Clang它的所有输入都是C ++源代码(-x c++
),然后才给它一个目标文件(semantic_actions.o
). Clang告诉您semantic_actions.o
不是UTF-8编码的C ++源文件.
You're telling Clang that all of its inputs are C++ sources (-x c++
), then you're giving it an object file (semantic_actions.o
). Clang's telling you that semantic_actions.o
is not a UTF-8 encoded C++ source file.
