运行./configure for vlc时找不到libavcodec

Question

我想在ubuntu 10.04上为vlc运行'./configure'.但由于某种原因,它无法找到libavcode库.我检查/ usr/lib,它有库,为什么./configure找不到它？

这是'./configure'的错误:

checking for AVCODEC... no
configure: error: Could not find libavcodec or libavutil. Use --disable-avcodec to ignore this error.

但我已经安装了libavcodec-dev,但它仍然失败:

$ sudo apt-get install libavcodec-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libavcodec-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 201 not upgraded.

我检查了'/ usr/lib',我看到了libavcodec.so:

-rw-r--r-- 1 root root 7339558 2010-03-04 04:42 libavcodec.a
lrwxrwxrwx 1 root root      21 2010-06-26 00:38 libavcodec.so -> libavcodec.so.52.20.1

感谢您的任何帮助.

Answer 1

apt-get build-dep vlc

...应该清除大多数(如果不是全部)vlc ./configure错误并且缺少依赖项

Answer 2

检查configure.log 也许它会提示您缺少什么。它可以是头文件而不是库。
