無法獲得GMP LIB與Emscripten

編譯

我和Emscripten的最新版本，試圖在這裏說明：https://github.com/kripken/gmp.js/blob/master/README.markdown 無法獲得GMP LIB與Emscripten

的某文件似乎是正確創建。然後我嘗試編譯針對庫（在調試模式），並且似乎工作：

然而，當我嘗試運行生成的JavaScript，我得到這個錯誤：

[email protected]:~/sources/gmp-5.0.2$ node complete.js 

/home/marcosscriven/sources/gmp-5.0.2/complete.js:2452

    at Function.Module._load (module.js:312:12)

阿龍（Emscripten的創造者），比上Emscripten谷歌集團說，這意味着該功能是不存在的，並與LLVM-VM，它確實出現了檢查：

[email protected]:~/sources/gmp-5.0.2$ !llvm-nm 
llvm-nm .libs/libgmp.a | grep gmpz_init 
00000000 T __gmpz_init

     U __gmpz_init

00000000 T __gmpz_init_set_d 
00000000 T __gmpz_init_set_si 
00000000 T __gmpz_init_set_str

     U __gmpz_init 
     U __gmpz_init_set_ui 
     U __gmpz_init2 
     U __gmpz_init_set_ui 
     U __gmpz_init 
     U __gmpz_init_set_str 
     U __gmpz_init 
     U __gmpz_init2 
     U __gmpz_init_set 
     U __gmpz_init 
     U __gmpz_init_set

所以我完全不知所措！

可能值得注意的是，在使用常規編譯器編譯時，編譯對庫的測試工作正常。

編輯：進一步與此。在這個lib的5.1.1版本中，他們引入了一個新的配置選項'--dissable-assembly'，它進行了一個通用的C編譯。

現在的問題是，測試運行時，它永遠不會停止。

有人建議我「禁用」在gmp.h可能，不太可能選擇：

https://github.com/kripken/gmp.js/blob/master/gmp-h.in

，但我看不出如何「禁用」它們的方式。通常有0或1個選項，但我在這裏沒有看到。我甚至不明白這個特定的選擇。

感謝

前導'_'的數量是否匹配？ – 2013-02-23 08:29:51

根據Alon（製作Emscripten的人），預計會出現額外的下劃線。 – 2013-02-23 12:49:34

我到底該工作。（事實上也適用於MPFR）。

最大的問題是確保使用32位選項和標題。
