我观察到,detect不会检测到非递归c++11 std::mutex上的递归锁。但是,在使用pthread_mutex_lock时会检测到问题。
两个简单的测试案例来演示这个问题:
// Test code: C++11 std::mutex
// helgrind does not detect recursive locking
void test_cpp11()
{
std::mutex m;
m.lock();
m.lock();
}
// pthread-based test code
// helgrind does detect recursive l
我有一个c++应用程序,我想作为deb包发布。我遇到的问题是不同计算机上的OpenCV版本不同。当在与编译不同的机器上运行程序时,它给出了error while loading shared libraries: libopencv_highgui.so.405: cannot open shared object file: No such file or directory。
然后我运行ldd,它回来了。
linux-vdso.so.1 (0x00007ffc1a7a3000)
libopencv_highgui.so.405 => not found
libopencv_video
在尝试使用Ubuntu14.04系统交叉编译ARM的Node.js v0.10.30 (Raspberry )时,我遇到了一个错误消息:

我试图在我的Ubuntu14.04服务器上使用,但我似乎无法安装gevent。我首先激活virtualenv,然后使用pip安装gevent:
