stl_vector.h 的 GCC 4.1.2 编译错误

Question

我在 GCC 4.1.2 上收到以下 STL 文件错误。并且相同的代码在 GCC 3.4.6 上正常工作，没有任何编译错误。
我在我的代码中包含了一些内置头文件，这些头文件又包含这些 STL 文件。因此，我无法修改头文件。

我使用以下代码编译它：

gcc  -I/grid/0/gs/java/jdk64/current/include -I/grid/0/gs/java/jdk64/current/include/linux -I/grid/0/tmp/direct/include/ydmg/ ydmg.cpp -I/grid/0/tmp/direct/include/ -o libydmg.so

编译时是否需要包含一些其他参数？

编译器版本可能是导致此问题的原因吗？

错误如下：

任何帮助将不胜感激。

这是 C++ 代码。 我正在使用 JNI 从 ydmg 和 yut 库中调用方法。 此代码在 gcc 3.4.6 上运行良好。它在 gcc 4.1.2 上给出错误。

#include <stdio.h>
#include "ydmg/bd.h"
#include <jni.h>
#include "yut/string.h"
extern "C" int getAge();

JNIEXPORT jint JNICALL Java_ydmgBd_getAge(JNIEnv *, jobject)
{

        ydmgBd bdObject;
        yutString s = bdObject.getKeys();
        printf("\ngetKeys() returns the key as : %s",s.c_str());

        yutHash user;
        yutString value = "abc";
        yutString key ="login";
        user.set(key,value);

        ydmgBd bd1(user);
        bool val = bd1.save(user);

        if(val){
                printf("\ntrue");
        }else {
                printf("\nfalse");
        }

        int age = bd1.getAge();

        printf("\nAge : %d ",age);
        printf("\nhi");

        return 1;
}

int main(){
        return 0;
}

Answer 1

如果你用gcc而不是g++编译cpp代码，你必须用-lstdc++链接，所以这个选项肯定是缺失的。

但是，问题已经出现在解析步骤，所以我的建议是检查命名空间......例如看看错误输出：

...
    ytl::std::operator!=
...

std 不应位于您的个人 ytl 命名空间中。你的包含有问题。

Answer 2

您的一个头文件几乎肯定包括：

#include <vector>

在该行之前，添加：

#undef max

而且我相信您的编译将开始工作。这发生在 b/c 你也在使用 C std 库，它对于某些函数使用宏，在这种情况下，会导致预处理器崩溃。我在 Linux 上也看到过同样的错误，我只需要取消定义该符号即可再次编译。
