如何給gd庫添加png 前面ＰＮＧ安裝成功 我修改了gd_png.c中include(png.h)為include(/usr/local/png/include/png.h) 然後make通過． /usr/local/png/為我安裝ＰＮＧ庫的目錄 如何給gd庫添加png 哦，你沒有指定 png 的 include 目錄 如何給gd庫添加png 我想應該是安裝ＰＮＧ的時候我選擇了目錄，如果是默認安裝的話，可能在便宜ＧＤ的時候就不需要修改此文件了吧． 如何給gd庫添加png 本人寫了個在在redhat 9.0中如何使PHP支持GD庫筆記，想使php支持ＧＤ庫遇到困難的朋友可以到http://www.518good.com/view.php?page=1&tid=155上看看． 如何給gd庫添加png 用 apt 或者 yum 的話，一句話就搞定了 ^_^ 如何給gd庫添加png rpm [ 關閉窗口 ]
