Question

我知道为什么我无法使用或无法在Lua中构建ProTeaAudio？

1）存在

[root@example ~]# yum install lua-devel
Loaded plugins: presto, refresh-packagekit
Setting up Install Process
Package lua-devel-5.1.4-4.fc12.i686 already installed and latest version
Nothing to do

2）无法构建RtAudio

[sun@example proteaAudio_src_090204]$ make
g++ -O2 -Wall  -DHAVE_GETTIMEOFDAY -D__LINUX_ALSA__  -Irtaudio -Irtaudio/include -I../lua/src -I../archive/baseCode/include -c rtaudio/RtAudio.cpp -o rtaudio/RtAudio.o

Lua试图告诉你它无法找到它试图在各种地方找到的模块"proAudioRt"的实现。第一个地方块是在Lua中加载实现的各种尝试，然后对可能包含该模块的各种共享对象文件进行了一些尝试。由于没有一个地方有效，require失败了。

没有用，因为你实际上没有构建包含模块的.so。

您需要清除所有编译和链接错误，以便构建proAudioRt.so。请注意，为了实际包含Lua模块，它必须具有名为luaopen_proAudioRt()的C可调用入口点，并带有签名

LUALIB_API int luaopen_proAudioRt(lua_State *L);

该函数应该构造模块的表，为其提供包含模块功能的成员。函数luaL_register()对此非常方便。

Lua用户wiki有binding to Lua部分也应该有用。

BUG - 带Lua的ProteaAudio不起作用
