Question

使用Cocos2d-x开发Android应用程序时出现崩溃。所以我使用的是ndk-stack，我收到了这个错误：

当我回到我的代码时。

bool CLuaScriptReader::RunScriptFile(const char *filename,char* ret_string,char *name){
    if( m_plua == NULL || ret_string == NULL || filename == NULL ) return false;
#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32
    char filebuff[MAX_LUA_FILE_LEN] = "";
    char line[1024] = "";
    FILE* fpFile = fopen(filename,"r");
    if( fpFile == NULL ) {
        printf("can not find file %s\n",filename);
        return false;
    }
    while( fgets(line, 1024, fpFile) != NULL) {
        strcat(filebuff,line);
    }
    fclose(fpFile);
    RunScriptBuffer(filebuff,ret_string,name);
#endif
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
    unsigned long int size = 0;
    unsigned char* filebuff = CCFileUtils::sharedFileUtils()->getFileData(filename,"r",&size);
    CCString* ccStr = CCString::createWithData(filebuff,size);
    RunScriptBuffer(ccStr->getCString(),ret_string,name);
#endif
    return true;
}

此行发生错误：

unsigned char* filebuff = CCFileUtils::sharedFileUtils()->getFileData(filename,"r",&size);

但是，我总是使用此代码在Android下读取文件。可以找到here

如何编译文件？

脚本似乎有问题。这些行：

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr ff7a8390
Stack frame #00  pc 0001055e  /system/lib/libc.so (dlmalloc+1729): Unable to ope
n symbol file e:\graduation_project\cocos2d-x-2.1.5\projects\Test_py\proj.androi
d\obj\local\armeabi\/libc.so. Error (9): Bad file descriptor

信号11-＆gt;内存失败，路径无处可去。 /适用于UNIX系统中的路径，以及适用于WINDOWS系统的路径，因此查找libc.so有错误

错误的文件描述符是linux，如果在尝试访问文件时收到此错误消息，则最突出的原因是文件系统损坏或磁盘块损坏。在这种情况下，您也会出现写入错误。
