c++ - STL_vector.h 的 GCC 4.1.2 编译错误

Question

对于 GCC 4.1.2 上的 STL 文件，我收到以下错误。同样的代码在 GCC 3.4.6 上可以正常运行，没有任何编译错误。
我在我的代码中包含一些内置 header ，这些 header 又包含这些 STL 文件。因此，我无法修改头文件。

我使用以下方式编译它:

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:

这是 C++ 代码。我正在使用 JNI 从 ydmg 和 yut 库调用方法。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;
}

如果你用 gcc 而不是用 g++ 编译 cpp 代码，你必须用 -lstdc++ 链接，所以这个选项肯定会丢失。

但是，问题已经出现在解析步骤，所以我的建议是检查 namespace ...例如查看错误输出:

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

std 不应在您的个人 ytl 命名空间中。你的包含有问题。
