Compiler errors SOX:安装libmad make[1]：***[all recursive]错误1&；make:**[全部]错误2

我希望你能帮助我。我想在我的系统上安装libmad和madplay，以便SOX能够解码mp3文件

我的系统：

cat /proc/version
Linux version 3.4.76-65.111.amzn1.i686 (mockbuild@gobi-build-31003) 
(gcc version 4.6.3 20120306 (Red Hat 4.6.3-2) (GCC) )

我所做的：

下载：

拆包

[user@ip ~]$ gunzip libmad-0.15.1b.tar.gz
[user@ip ~]$ tar xfv libmad-0.15.1b.tar

./configure（我知道这很重要，也不知道是否相关，但我会针对我遇到的错误给出一次）

如果我想用“make”编译它，我会得到以下错误：

看起来代码很旧。

-fforce mem

选项在GCC中已多年不受支持。例如，请参见

如果您只是想让它正常工作，我建议您查看

Makefile

文件中对

-fforce mem

的引用，然后删除该标志。请注意，每次重新运行

configure

时，您都必须再次执行此操作，因为

Makefile

文件将被重新创建

如果你想“真正”修复它，你必须在autoconf和automake文件中找到使用它的地方，然后从那里删除它

---

我还发现非常奇怪的是，代码迫使体系结构成为

i486

，这真的很旧，而且速度会慢得多。除非你真的有一个

i486

，我觉得这在2014年是不太可能的。

真的很感谢我删除了

optimize=“$optimize-fforce mem

文件

configure

和

configure.ac

中的一行，它解决了我的问题。
