一、编译dalvik_system_Zygote.c报错

1、错误内容：

dalvik/vm/native/dalvik_system_Zygote.c: In function ‘setrlimitsFromArray’:
dalvik/vm/native/dalvik_system_Zygote.c:191: error: storage size of ‘rlim’ isn’t known
dalvik/vm/native/dalvik_system_Zygote.c:214: warning: implicit declaration of function ‘setrlimit’
dalvik/vm/native/dalvik_system_Zygote.c:191: warning: unused variable ‘rlim’
make: *** [out/host/linux-x86/obj/SHARED_LIBRARIES/libdvm_intermediates/native/dalvik_system_Zygote.o] 错误 1

2、背景：Ubuntu 13.04 编译android 2.3.1 源代码
3、源代码部分：

static int setrlimitsFromArray(ArrayObject* rlimits)
{
    u4 i;
    struct rlimit rlim; //此处是第191行

    if (rlimits == NULL) {
        return 0;
    }

    memset (&rlim, 0, sizeof(rlim));

    ArrayObject** tuples = (ArrayObject **)(rlimits->contents);

    for (i = 0; i < rlimits->length; i++) {
        ArrayObject * rlimit_tuple = tuples[i];
        s4* contents = (s4 *)rlimit_tuple->contents;
        int err;

        if (rlimit_tuple->length != 3) {
            LOGE("rlimits array must have a second dimension of size 3");
            return -1;
        }

        rlim.rlim_cur = contents[1];
        rlim.rlim_max = contents[2];  //214

        err = setrlimit(contents[0], &rlim);

        if (err < 0) {
            return -1;
        }
    }

    return 0;
}

4、解决方法：

需要在源码前面添加头部文件#include <sys/resource.h>
