我修改了FreeImage 3.16.0隨附的Makefile.osx文件，使用Clang進行編譯並使用最新的10.8 Mac OS X SDK，它已經擺脫了大部分的問題，但是我完全停留在一些我無法找到任何信息的鏈接器錯誤上。在Mac OS X上使用make和Clang連接FreeImage 3.16.0的問題10.8
我改性過的計算器上這個其他職位的建議生成文件：How to compile FreeImage on Mac OS X 10.8?
而這正是它目前的樣子：

# This file can be generated by ./gensrclist.sh
include Makefile.srcs

我得到的鏈接錯誤是什麼在LibJXR據我可以告訴：

我真的不知道該怎麼來嘗試解決這個問題，特別是因爲它只是發生對於i386配置，x86_64配置似乎很好。
