C++ JNI在執行任何IO /流時崩潰/掛起

2016-09-26 41 views

當我嘗試編譯C++代碼以在JAVA端使用時，似乎遇到了很大的問題。當我嘗試執行任何與IO /流/操作相關的任何操作時，JVM似乎崩潰了。C++ JNI在執行任何IO /流時崩潰/掛起

有時，當我運行應用程序時，每10次運行一次，JNI與所有IO東西一起工作100％。然後剩下的時間JVM崩潰或掛起。

我使用：的Windows 10 64，JAVA jdk1.8.0_102上，NetBeans 8.1，G ++，附加選項：-D__int64 =的int64_t

當我做這些，JNI的正常工作：

JNIEXPORT jstring JNICALL Java_Main_nativePrint 
    (JNIEnv *env, jobject) 
{ 
    return env->NewStringUTF("HELLO"); 
} 

JNIEXPORT jstring JNICALL Java_Main_nativePrint 
    (JNIEnv *env, jobject) 
{ 
    double var = std::sqrt(100); 
    return env->NewStringUTF("HELLO"); 
}

當我試圖合併的內容，如printf，std::stringstream，sprintf，cout，或puts，JVM的崩潰。甚至實例化std::stringstream似乎讓我崩潰。我認爲其他種類的操作功能也崩潰了我：

Java_Main_nativePrint(JNIEnv *env, jobject instance) 
{ 
    int variable = 100; 
    char str[15]; 

    //CRASHES ON HERE 
    sprintf(str, "%d", variable); 
    //CRASHES ON HERE IF ABOVE COMMENTED OUT OR USING ANOTHER CHAR ARRAY. 
    puts(str); //CRASHES ON HERE 

    return env->NewStringUTF(str); 
} 

JNIEXPORT jstring JNICALL Java_Main_nativePrint 
    (JNIEnv *env, jobject) 
{ 
    double res = std::sqrt(100); 

    //CRASHES HERE ON INSTANTATION OF stringstream 
    std::stringstream ss; 
    //ss << std::sqrt(100); 
    //const char* str = ss.str().c_str(); 

    return env->NewStringUTF("HELLO"); 
}

我似乎有類似的問題，以這個人：

JNI with c++ keeps crashing on cout, printf and method calls

這裏是我的轉儲：

你是如何構建你的JNI庫的？ MSVC？轉儲信息在哪裏？ – rustyx

@RustyX當我運行應用程序時，它現在似乎掛起來了，但我發佈了一些在它崩潰前輸出的轉儲文件。它應該包含所有的信息。 –

使用靜態或動態鏈接的C++庫，使用g ++編譯您的本地庫嗎？如果是後者，你是從Java代碼中加載它的嗎？ –

@RustyX很可能是正確的。即使在單個進程中混合使用多個C++運行時庫，如果可能的話也不太可能奏效。

JVM似乎依賴於Microsoft C++運行時。添加GNU C++運行時不太可行。這從MinGW的網頁地址的一些問題：

Interoperability of Libraries Created by Different Compiler Brands

...

即使GNU G ++現在可以鏈接MSVC C++庫，並能產生 MSVC++兼容庫/ DLL文件，這並不意味着它們將會是 由於C++的動態特性而能夠在運行時工作。一些 可能的原因是：

  • 簡單的名稱修復問題，它可以用一個明確的.def文件繞過。
  • 需要正確編譯器選項的不同結構對齊問題（-mms-bitfields，...）。
  • 底層異常和內存模型的基本衝突：
    • 新的/刪除或的malloc /免費的MSVC DLL不會與合作，Cygwin的newlib新/刪除或的malloc /免費。不能釋放空間 ，這個空間在使用不同的new/malloc的函數中被分配。
    • 由MSVC DLL引發的異常不會被Cygwin可執行文件捕獲，反之亦然。
    • 緩慢的GNU SJLJ異常模型（在GCC-3中使用）。x和更早的版本）與MSVC++模型兼容，但新的DWARF2模型（其中 將被GCC-4.x使用）將不兼容。

解決存儲器管理兼容性問題和不同new/delete和malloc/free實現之間的衝突將是困難的，如果不是不可能的。

從Cygwin切換到MiniGW已經解決了我所有的問題！ –
