compiler-errors - SOX : installing libmad make[1]: *** [all-recursive] Error 1 & make: *** [all] Error 2

Question

我希望你能帮助我。我想在系统上安装libmad和madplay，以便SOX可以解码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) )
#1 SMP Tue Jan 14 21:06:12 UTC 2014

我所做的:

Answer 1

看起来该代码是旧的。多年来，GCC一直不支持-fforce-mem选项。参见例如gcc's -fforce-mem option。

如果您只是想使它正常工作，建议您浏览Makefile文件以获取对-fforce-mem的引用，然后简单地删除该标志。请注意，由于您将重新创建configure文件，因此每次您重新运行Makefile时，都必须再次进行操作。

如果要“真正”修复它，则必须去查找使用它的autoconf和automake文件中的位置，然后从中删除它。

我也感到很奇怪，该代码迫使该体系结构为i486，它确实很旧，而且会慢很多。除非您确实有i486，否则在2014年我不太可能找到。
