我在c ++库(openNN)中遇到检查方法的问题我试图在Xcode中编译。我将使用其中一种方法的示例,因为我怀疑它们都是由同一问题引起的。
标题声明,我收到错误:
预期会员姓名或';'在声明说明符之后。

功能定义:
void check(void) const;
如果我将标题中的定义更改为
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
}
我最终得到了错误:
会员的额外资格&#39;检查&#39;
我目前正在使用方言C ++ 98和Library libc ++。
Xcode被设置为将源代码编译为Objective-C ++,它可以处理大多数其他错误。
我无法想到与此问题相关的任何其他内容,它让我难以忍受数小时,因此非常感谢任何类型的帮助。
答案 0 :(得分:6)
不知道您的确切设置,但是当源代码引用AssertMacros.h
并且还有check
方法的某些定义时,已经historical reports。在我的测试代码中:
#include <stdio.h>
#include <AssertMacros.h>
class InverseSumSquaredError {
public:
void check(void) const;
}
我发现了同样的错误。包括这一行:
#define __ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES 0
在包含AssertMacros.h
之前解决问题。
