针对“undefined reference to pthread_mutex_trylock'”的错误,这通常意味着在编译过程中链接器未能找到pthread_mutex_trylock`函数的定义。这个函数是POSIX线程(pthread)库的一部分,用于尝试锁定一个互斥锁,如果锁当前不可用,函数会立即返回而不是阻塞。以下是一些可能的解决步骤: 确认pthread_mutex_trylock函数的使用环...

2017-06-17 21:43 −我们来考察下pthread中锁的实现。 首先看下初始化宏:PTHREAD_MUTEX_INITIALIZER。 # define PTHREAD_MUTEX_INITIALIZER \ { { 0, 0, 0, 0, 0, __PTHREAD_SPINS, { 0, 0 } } } /* D... pslydhh 0 11504 undefined reference to `android::Mutex::lock()' ...
when I use 'make -j 9',the error is found ,"undefined references to `pthread_mutex_trylock'" follow ,I use pcl-1.10.
解决办法:undefined reference to symbol 'pthread_mutexattr_settype@@GLIBC_2.2.5',当时吾就傻眼了,赶紧上网一查链接加上:-L../boost/stage/lib-pthread好怪异!是的,可是已经编译通过啦.
