firefox 3 (xulrunner) 需要apng支持的libpng，怎么解决？

younker

emerge mozilla firefox 3.0 或者xulrunner的时候， 在configure的时候要检查libpng对apng的支持， 但是系统的png是不支持apng的，总是失败在configure上面，不知道大家是怎么解决的？

你的libpng什么版本的？

younker

libpng-1.2.27 from portage.

我刚才试了一下，我用libpng-1.2.27 from portage也是可以的，你试试sync一下portage，然后再重新emerge 一下libpng和xulrunner看看。

younker

试验了n次了，都出现这个问题。我用的glibc-2.8-20080602版本的。gcc4.3.1不知道有没有影响

lingyunxs

可能是gcc4.3.1的问题吧，不过你可以安装firefox-bin版试试，也很好用的

younker

这个东西和编译器也有关系？
不太可能吧？

zhllg

看config.log

有时侯把/usr/portage/distfiles/下面的源码包解压出来，重新手动configure+make会有意想不到的收获

再不知道什么出问题的情况下，不推荐楼上的方法。Portage 也是这样，只不过是用了个小黑盒了，原则上会得到一样的结果。楼主可以按 zhllg 版主的要求把 config.log 帖出来分析分析。
