iphone - valgrind和iphone

Question

我想使用valgrind来检测iPhoneSimulator上的泄漏。我得到了valgrind的源代码，进行了编译和安装。在我的代码中添加了以下内容

int main(int argc, char *argv[]) {

#ifdef VALGRIND_REXEC
    if (argc = 2 && strcmp(argv[1], "-valgrind") != 0)) {
        execl(VALGRIND, VALGRIND, "--leak-check=full", "--dsymutil=yes", argv[0], "-valgrind", NULL);
    }
#endif

定义了VALGRIND_REXEC，当我尝试调试或运行应用程序时，在控制台中出现以下错误

[Session started at 2011-03-14 16:21:27 +0000.]
Detected an attempt to call a symbol in system libraries that is not present on the iPhone:
open$UNIX2003 called from function main in image valgrind.
If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first.

Mac 10.6.5
Xcode 3.2.5
iOS 4.2

我需要以任何特殊方式编译valgrind，我做错了什么吗？

出于好奇，出于某种原因，Xcode中的“泄漏”工具不会执行您需要的操作吗？
