Xcode编译C ++预期成员名称或';'时出错声明后声明符 [英] Xcode error compiling c++ Expected member name or ';' after declaration specifiers
问题描述
我正在尝试在Xcode中进行编译的c ++库(openNN)中的检查方法存在问题.我将以其中一种方法为例,因为我怀疑它们都是由同一问题引起的.
I'm having issues with the checking methods in a c++ library (openNN) i'm trying to compile in Xcode. I'll use an example of one of the methods as i suspect they are all caused by the same issue.
出现错误的标头声明:
期望的会员名称或';'在声明说明符之后.
Header declaration where i get the error:
Expected member name or ';' after declaration specifiers.
void check(void) const;
函数定义:
void InverseSumSquaredError::check(void) const
{
std::ostringstream buffer;
// Neural network stuff
if(!neural_network_pointer)
{
buffer << "OpenNN Exception: InverseSumSquaredError class.\n"
<< "void check(void) const method.\n"
<< "Pointer to neural network is NULL.\n";
throw std::logic_error(buffer.str().c_str());
}
const MultilayerPerceptron* multilayer_perceptron_pointer = neural_network_pointer->get_multilayer_perceptron_pointer();
if(!multilayer_perceptron_pointer)
{
buffer << "OpenNN Exception: InverseSumSquaredError class.\n"
<< "void check(void) const method.\n"
<< "Pointer to multilayer perceptron is NULL.\n";
throw std::logic_error(buffer.str().c_str());
}
const unsigned int inputs_number = multilayer_perceptron_pointer->count_inputs_number();
const unsigned int outputs_number = multilayer_perceptron_pointer->count_outputs_number();
if(inputs_number == 0)
{
buffer << "OpenNN Exception: InverseSumSquaredError class.\n"
<< "void check(void) const method.\n"
<< "Number of inputs in multilayer perceptron object is zero.\n";
throw std::logic_error(buffer.str().c_str());
}
if(outputs_number == 0)
{
buffer << "OpenNN Exception: InverseSumSquaredError class.\n"
<< "void check(void) const method.\n"
<< "Number of outputs in multilayer perceptron object is zero.\n";
throw std::logic_error(buffer.str().c_str());
}
// Mathematical model stuff
if(!mathematical_model_pointer)
{
buffer << "OpenNN Exception: InverseSumSquaredError class.\n"
<< "void check(void) const method.\n"
<< "Pointer to mathematical model is NULL.\n";
throw std::logic_error(buffer.str().c_str());
}
// Data set stuff
if(!data_set_pointer)
{
buffer << "OpenNN Exception: InverseSumSquaredError class.\n"
<< "void check(void) const method.\n"
<< "Pointer to data set is NULL.\n";
throw std::logic_error(buffer.str().c_str());
}
// Final solutions error stuff
}
如果我将标题中的定义更改为
void InverseSumSquaredError::check(void) const;
我最终遇到错误:
成员检查"的额外资格
我当前正在使用方言C ++ 98和库libc ++.
Xcode设置为将源代码编译为Objective-C ++,可解决大多数其他错误.
If i change the definition in the header to
void InverseSumSquaredError::check(void) const;
I end up with the error:
Extra qualification on member 'check'
I'm currently using the dialect C++98 and Library libc++.
Xcode is set to compile sources as Objective-C++ which takes care of most of the other errors.
我想不出与此问题相关的任何其他信息,因为它困扰了我好几个小时,所以非常感谢您提供任何类型的帮助.
I can't think of anything else relevant to this issue, it's had me stumped for hours, so any type of help is much appreciated.
推荐答案
不知道您的确切设置,但是有AssertMacros.h并且还具有check
方法的某些定义时,="nofollow noreferrer">报告.在我的测试代码中:
Don't know your exact setup, but there have been historical reports when source code references AssertMacros.h
and also has some definition of a check
method. In my test code:
#include <stdio.h>
#include <AssertMacros.h>
class InverseSumSquaredError {
public:
void check(void) const;
}
我观察到相同的错误.包括以下行:
I observed the same error. Including the line:
#define __ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES 0
在包含AssertMacros.h
之前可以解决此问题.
prior to including AssertMacros.h
fixes the issue.
