我已经花了10个小时试图找出这个。我尝试了一堆不同的库，试图让ogg或mp3文件与allegro 4一起玩。我下载了DUMB库，并将include和lib文件复制到mingw各个地方（我使用的是代码块）。 将库安装到编译器的正确方法是什么？ 这是我目前的代码..

答案 0 :(得分：0)
DUMB要求您链接两个库，核心libdumb，然后是aldumb“glue”。看起来你只是与后者联系。订单也很重要。
请注意，DUMB用于播放MOD文件（以及各种变体）。如果您需要ogg支持，如果您安装了官方ogg库，它将在Allegro 4.4中内置。
此外，如果您刚开始使用，那么您应该真正使用Allegro 5.版本4不再受支持，在现代操作系统上也无法正常工作。
