好鬼啊，明明有pcre，可是死活報找不到，原來是缺少mysql_devel，浪費了好幾個小時~
I was trying to compile ArcEMU on Fedora and I kept geting the following error:
configure: error: Couldn’t find pcre library. Make sure your pcre path is correct.
Turns out if you don’t have the mysql-devel packages installed you get this error. That makes a lot of sense. After an hour of searching the web and building pcre over from scratch a dozen times, I finally found a post that mentioned a problem with using mysql-devel 64bit packages. I checked and didn’t have mysql-devel installed, so I installed it and it compiles just fine now.
