我无法编译我的C ++程序。如您所见，我正在编写Node.js插件。这是代码（Eamorr_addon.cpp）：
#include <iostream>
#include <v8.h>
#include <node.h>
#include <gmp.h>
#include "Definitions.h"
#include "Rk.h"
#include "tbb/concurrent_hash_map.h"
//#include <tbb/concurrent_vector.h>
using namespace std;
using namespace v8;
static Handle<Value> Echo(const Arguments& args) {
HandleScope scope;
if (args.Length() < 1) {
return ThrowException(Exception::TypeError(String::New("Bad argument")));
}
return scope.Close(args[0]);
}
extern "C" void init (Handle<Object> target)
{
HandleScope scope;
target->Set(String::New("hello"), String::New("world"));
NODE_SET_METHOD(target, "echo", Echo);
}
当我删除行#include "tbb/concurrent_hash_map.h"时，一切正常。
这是我的gyp make文件：
{
'targets': [
{
'target_name':'Eamorr_addon',
'sources':['src/Eamorr_addon.cpp'],
'include_dirs': ['/usr/include','/usr/local/include/'],
'cflags': ['-Wall','-fopenmp'],
'ldflags': ['-ltbb','-lgmp']
}
]
}
当我执行node-gyp build时，我收到以下错误信息，而这些错误无法解决问题：
node-gyp build
info it worked if it ends with ok
spawn make [ 'BUILDTYPE=Release', '-f', 'Makefile.gyp' ]

有人可以提出任何建议吗？
编辑：
这是＆＃34; Rk.h＆＃34;：
#ifndef RK_H_
#define RK_H_
#include <gmp.h>
#include "Definitions.h"
unsigned long int init_rkHash(char* str);
unsigned long int get_rkHash(unsigned long int prevHash,int prevAscii,int topAscii);
/*unsigned long int getFirstPrevHash(char* &buffer);*/
#endif /* RK_H_ */
这里是＆＃34; Definitions.h＆＃34;：
#ifndef DEFINITIONS_H_
#define DEFINITIONS_H_
#define PORT 10002
#define CHUNKSIZE 512
#define PRIME 9223372036854775783
#define D 2
#endif /* DEFINITIONS_H_ */
答案 0 :(得分：9)
#define宏很容易使用错误。给他们一些像D这样的名字会引发问题。
您将D定义为
#define D 2
现在，如果我们查看atomic.h，我们会发现例如。
...
template<typename I, typename D, typename StepType>
struct atomic_impl_with_arithmetic: atomic_impl<I> {
...
value_type fetch_and_add( D addend ) {
...
template<memory_semantics M>
value_type fetch_and_decrement() {
return fetch_and_add<M>(__TBB_MINUS_ONE(D));
}
...
查看相关性？
你得到的是：
...
template<typename I, typename 2, typename StepType>
struct atomic_impl_with_arithmetic: atomic_impl<I> {
...
value_type fetch_and_add( 2 addend ) {
...
template<memory_semantics M>
value_type fetch_and_decrement() {
return fetch_and_add<M>(__TBB_MINUS_ONE(2));
}
...
这不是有效的C ++。
解决方案：不要给宏提供可能会发生冲突的名称。经验法则：每个整洁的名称在一生中至少会发生一次冲突并产生微妙而虚幻的错误信息，这些信息可能会感染一个可怜的维护者（你呢？）夜间梦想与难以形容的恶魔的幻想。因此，如果绝对必须，只使用宏。
如果D应该是一个整数（但除了你之外，谁知道该名称？），你可以做以下其中一项：
enum { D = 2 };
或
extern const int D; // in a header
const int D = 2; // in exactly one source file
或者您可以重新考虑您的决定D是否需要保持不变，而是将其作为参数传递给您的函数和类。
答案 1 :(得分：1)
以下是tbb / atomic.h
的摘录
template<typename I, typename D, typename StepType>
struct atomic_impl_with_arithmetic: atomic_impl<I> {
public:
typedef I value_type;
template<memory_semantics M>
value_type fetch_and_add( D addend ) {
return value_type(internal::atomic_traits<sizeof(value_type),M>::fetch_and_add( &this->rep.value, addend*sizeof(StepType) ));
}
...
现在，如果您从Definitions.h替换D的定义，您将看到问题所在。一般来说，使用这样的名称制作宏定义是个坏主意。如果您有太多依赖于D的代码，您可以通过取消定义包括tbb标头来解决问题，如下所示：
#include "Definitions.h"
#include "Rk.h"
#pragma push_macro("D")
#undef D
#include "tbb/concurrent_hash_map.h"
#include <tbb/concurrent_vector.h>
#pragma pop_macro("D")
