Plugins 编译Ethos框架时出错

我正在Mac OS Lion上制作Ethos框架。 git://git.dronelabs.com/ethos

这里是./configure的结果：

Ethos 0.2.3 
  Prefix...................:  /usr/local
  Debug level..............:  minimum
  Maintainer Compiler flags:  no
  Build API reference......:  no
  Enable test suite........:  yes
Bindings
  GObject Introspection....:  no
  Vala Bindings............:  no
  Python Bindings..........:  no
  Javascript Bindings......:  no
Now type `make' to compile ethos

然后我执行sudo make，编译时出现错误：

Making all in c-plugins
CC    libsample.so
Undefined symbols for architecture x86_64:
"_ethos_plugin_get_type", referenced from:
   _my_plugin_get_type in cc3gPLKS.o
   _my_plugin_class_init in cc3gPLKS.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[3]: *** [libsample.so] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

如何修复它？

经过以下修改后，我发现Ethos可以安装在Mac OS X 10.7上：

1） 编辑文件：etos_dir/etos/etos_manager.c（：194）：

致：

2） 禁用制作：ethos目录/测试， Makefile.am中的更改

致：

这是必要的，因为在制作过程中，它找不到libetos

    if (loader != NULL)
