我现在在QNX6.3下编译mplayer
版本是：MPlayer-1.0pre4
在编译的时候出现错误：
-lpthread -ldl -rdynamic -lm
libvo/libvo.a(font_load_ft.o)(.text+0x1fd9): In function

collect2: ld returned 1 exit status
make: *** [mplayer] Error 1

请问有什么解决方法

编译、安装libiconv

谢谢xtang

我现在在qnx下执行

mplayer 208.MPG
但是不出现画面

安装网上的写法
mplayer -vo sdl:driver=photon 208.MPG

会出现下面的错误,想问问应该如何解决.

你安装了SDL了吗？

先编译、安装SDL，然后在MPlayer的configure里告诉它用SDL以及SDL的PATH，这样生成的MPlayer有SDL支持，就可以用 -vo 来指定了.

5

谢谢xtang

我安装了SDL的qpr包
那我应该如何指定SDL的位置

./configure后

Checking for SDL … no

6

重新装了SDL
直接运行系统死掉

7

./configure --help 一下看看，我记得有个指定SDL路径的选项。

还有一个可以试的，是去下载SDL的源码，自己编一个吧。SDL应该可以直接在QNX6上编译。

8

我安装了sdl-1.2.7.tar.gz
但是我在运行的时候

mplayer -vo sdl /root/208.MPG的时候
我系统的photon死掉了,播放的画面花屏,系统的服务进程都死了,想知道如何查看系统死掉的原因
