我正在尝试在redhat上安装apc，所以我做了：
pecl install apc 我说对了：
Use apxs to set compile flags (if using APC with Apache)? [yes]:
我得到这个：
checking for re2c... no configure: WARNING: You will need re2c 0.9.11 or later if you want to \ regenerate PHP parsers.
和
checking whether apc needs to get compiler flags from apxs... Sorry, I was not able to successfully run APXS. Possible reasons: 1. Perl is not installed; 2. Apache was not compiled with DSO support (--enable-module=so); 3. 'apxs' is not in your path. Try to use --with-apxs=/path/to/apxs The output of apxs follows /tmp/tmpJQuZdD/APC-3.0.16/configure: line 3846: apxs: command not found configure: error: Aborting ERROR: `/tmp/tmpJQuZdD/APC-3.0.16/configure --with-apxs' failed
可能是什么问题呢？ 谢谢
你忘了这个包：
sudo yum install httpd-devel.i386
要么
sudo yum install httpd-devel
您也可能需要：
apt-get install apache2-threaded-dev
一旦完成，再试一次，最后重启apache：
sudo apachectl -k graceful
