[2/2]禁用 Overlays 同版本软件|gcc 生成二进制文件格式

亞利艾爾

1.问题表述：Gentoo 规定：相同软件如果在 Overlay 中和 Portage 中最新的可用版本如果一样，将只用 Overlay 中的。我用 gentoo-china 的 realplayer-10.0.9 出了问题，问一下如何禁用 Overlay 的，使用 Portage 的？
　　顺便加上我的 RealPlayer 出错信息，有兴趣的朋友可以看看：

39. The program 'realplay.bin' received an X Window System error.
40. This probably reflects a bug in the program.
41. The error was 'BadMatch (invalid parameter attributes)'.
42.   (Details: serial 32 error_code 8 request_code 140 minor_code 13)
43.   (Note to programmers: normally, X errors are reported asynchronously;
44.    that is, you will receive the error a while after causing it.
45.    To debug your program, run it with the --sync command line
46.    option to change this behavior. You can then get a meaningful
47.    backtrace from your debugger if you break on the gdk_x_error() function.)

原问题不再提问，问题解决。Realplayer 播放指定文件需要 faac 库。
2. 问题表述：用 gcc 1.c 编译出来的二进制程序文件名默认是a.out，这是惯例还是说格式是 a.out 格式而不是 ELF 格式？
回答：费话，肯定是 ELF 啦～

谢谢大家。

file a.out
其实是ELF格式
文件名和格式怎么会有关呢

是没有必然关系。但人的认识总是从表面开始的，看到这个有点吓人。网上都是说 97 年几乎没有 a.out 文件了，但没说这个，不太肯定……
