求助：apr 是什么？

azhoulinux

checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
configure failed for srclib/apr
－－－－－－－－－－－－－－－－－－
编译apache 时的错误，apt-get install libapr0  libapr0-dev 后可以编译apache,

不过，我一直想知道apr是什么？lib应该是链接库文件
与apache有什么关系？

The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform-specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
