sem_init函数被弃用(deprecated)的原因主要是出于安全性和可移植性的考虑。在某些平台或环境中,使用sem_init创建的未命名信号量可能不会正确地与进程的其他部分或子进程共享,这可能导致竞态条件和其他并发问题。此外,随着操作系统和C标准库的发展,新的同步机制可能提供了更安全、更高效或更易于使用的替代方案。 2. ...

Function ereg() is deprecated及解决办法 因为是在Drupal中遇到的问题,所以就在Drupal中解决。原因很简单,就是Drupal 6.x不支持PHP 5.3,Drupal 7没有这个问题,解决办法也很多。最简单的莫过于降级到PHP 5.2.x,如果由于一些特别的原因必须使用PHP 5.3+的话,可以尝试下列办法。
例如,在C ++中,当使用属性alloc_align , assume_aligned , assume_aligned , format , format_arg , malloc或assume_aligned声明的主模板的显式特化未声明时,会发出警告。 deprecated属性, error和warning抑制警告。 (请参阅功能属性 )。 -Wmissing-attributes由-Wall启用。

This is unfortunate but C++11 deprecated std::auto_ptr. CharLS codebase should be updated in favor of std:unique_ptr. It may be non-trivial to have a portable solution, see: http://programmers.stackexchange.com/questions/291141/how-to-ha...
