我正在尝试在 ubuntu 中安装 pymedia 以使用 python 2.7 运行脚本。因此，我追踪了依赖项并安装了它们：
sudo apt-get install python-dev libogg-dev libvorbis-dev liblame-dev libfaad2-dev libasound2-dev python-pygame libmp3lame-dev libevent-dev
因此，当我完成上述安装后，在下一步构建 pymedia 时，我得到了以下内容：

从打印结果可以看出，这些软件包（尽管安装正确）被标记为“未找到”。错误行的底部对我来说看起来像是 gcc 错误。如果有人能指出这里可能出现的问题，那将非常有帮助。
答案1
很多人都遇到过这个问题 - 这很可能是由于脚本混乱造成的。
显然，64 位共享库必须使用该标志进行编译-fPIC，而在这种情况下，sound.cpp 则不需要。
其中setup.py有一个名为disable_fPIC()- 的函数，您可以通过用语句替换属于它的所有代码来禁用该函数pass。所以：
def disable_fPIC():
pass
