void abort() 的声明抛出不同的异常
我正在尝试为 Festival 编写一些 C++ 代码（使用 C++ API），但在尝试编译时遇到了困难。以下是我调用 g++ 的方法：
g++ -Wall -pedantic -I../ -I../speech_tools/include/ helloFestival.C -oh -L../festival/src/ lib/libFestival.a -L../speech_tools/lib/libestools.a -L../speech_tools/lib/libestbase.a -L../speech_tools/lib/libeststrings.a |& tee Festival.runLog 我得到的错误是：
In file included from ../speech_tools/include/EST.h:48,
from ../festival/src/include/festival.h:47,
from helloFestival.C:4:
../speech_tools/include/EST_String.h:50: error: declaration of ‘void abort()’ throws different exceptions
/usr/include/stdlib.h:513: error: from previous declaration ‘void abort() throw ()’
EST_String.h 中的违规行将是：extern "C" void abort(void);
我使用的 main() 函数可以在这里找到：festvox.org/docs/manual-1.4.3/festival_28 .html#SEC133
这里给出的编译和链接指令是我使用过的。
我在网上查看过这个问题，一些解决方案表明这可能是因为向后兼容性，或者从析构函数中调用 abort() 等。我的问题是：
- 如何摆脱这个问题？
- 为什么我会看到这个错误？
I am trying to write some C++ code (using the C++ API) for Festival and am getting stuck while trying to compile. Here is how I invoke g++:
g++ -Wall -pedantic -I../ -I../speech_tools/include/ helloFestival.C -o h -L../festival/src/lib/libFestival.a -L../speech_tools/lib/libestools.a -L../speech_tools/lib/libestbase.a -L../speech_tools/lib/libeststrings.a |& tee festival.runLog
The error I get is:
In file included from ../speech_tools/include/EST.h:48,
from ../festival/src/include/festival.h:47,
from helloFestival.C:4:
../speech_tools/include/EST_String.h:50: error: declaration of ‘void abort()’ throws different exceptions
/usr/include/stdlib.h:513: error: from previous declaration ‘void abort() throw ()’
The offending line in EST_String.h would be:extern "C" void abort(void);
The main() function I have used can be found here: festvox.org/docs/manual-1.4.3/festival_28.html#SEC133
The compilation and linking instructions given here are the ones I have used.
I have looked this problem on the net and some of the solutions suggest that it maybe because of backward compatibility, or calling an abort() from within a destructor etc. My questions are:
- How do I get rid of this?
- Why do I see this error?

您会看到此错误，因为 voice_tools 中的 abort() 函数与标准规定的 abort() 函数冲突。可能没有真正好的、干净的方法来解决这个问题。如果您自己编写了 EST_String.h，请以不同的方式命名该函数。
如果不是，请勿将 stdlib.h 和 EST_String.h 包含在同一文件中。是的，这有限制而且很糟糕，但你现在的处境很糟糕。
You see this error because the abort() function in speech_tools conflicts with the standard-mandated abort() function. There's probably no really good, clean way to fix this. If you have written EST_String.h yourself, name the function differently.
If not, don't include stdlib.h and EST_String.h in the same file. Yes, that's limiting and bad, but you are in a crappy situation here.
这是一个非常基本的 C 错误。中止的两个定义是冲突的我会尝试删除 EST_String.h 中的行，并可能添加一个
#include并查看它是否在之后编译那。It is a very basic c error. The two definition for abort are conflicting I would try to remove the line in
EST_String.hand maybe add a#include <stdlib.h>and see if it compiles after that.我不认为包含 stdlib 标头是问题所在。但是，通过将
理由：以防万一
所以我真的建议......只是摆弄它。如果这两种方法都不起作用（确保没有冲突的包含或过时的预编译头），我建议删除 EST_String.h 中的违规声明
I don't suppose including the stdlib header is the problem. However, you might get better mileage from including either
<cstdlib>or<stdlib.h>as the very first header in your translation unitsRationale: just in case the definition in
<cstdlib>adds the no-throw declspec.So I really suggest to ... just fiddle with that. If it doesn't work either way (make sure you don't have conflicting includes or stale precompiled headers), I suggest just removing the offending declarion in EST_String.h
今天这仍然是一个问题。作为解决方法，我正在使用这段代码。
它很丑陋而且很老套，但可以正常工作：
This is still a problem today. As a workaround, i'm using this piece of code.
It's ugly and hacky, but gets it working:
