GMP-chudnovsky.c和Xcode的4.5

Question

當我嘗試編譯和運行GMP-chudnovsky.c文件中找到here與Xcode中出現以下錯誤：

Undefined symbols for architecture x86_64: 
    "_fac_clear", referenced from: 
     _main in main.o 
    "_fac_compact", referenced from: 
     _fac_remove_gcd in main.o 
    "_fac_init", referenced from: 
     _main in main.o 
    "_fac_mul", referenced from: 
     _bs in main.o 
    "_fac_mul_bp", referenced from: 
     _bs in main.o 
    "_fac_resize", referenced from: 
     _fac_remove_gcd in main.o 
    "_fac_set_bp", referenced from: 
     _bs in main.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

我知道gmp library是否正確安裝，因爲我有另一個xcode項目鏈接到它正在編譯正確。任何想法爲什麼發生這種情況？

忘了說我已經加入路徑頭文件和庫GMP以及在其它鏈接器標記

解決添加-lgmp標誌：看this answer。

我認爲xcode首先在Debug配置中運行，其中沒有執行優化，也沒有執行內聯操作。這意味着任何inline功能也必須製作成static。
