構建和使用包含覆蓋功能的pnacl-compiler-rt

我目前在使用pnacl-compiler-rt時遇到了一些嚴重問題，因爲我沒有成功找到任何有關構建它的信息（在Mac上，這可能與NaCl的情況相關或不相關）與儀器的東西（如包括GCDAProfiling）。我最近嘗試是修改make/options.mk：構建和使用包含覆蓋功能的pnacl-compiler-rt

#Added this 
FUNCTIONS := GCDAProfiling

我查庫，看看它是否在那裏使用ar -t libcompiler_rt.a：

我已經複製這個庫到pepper_49/lib/clang-newlib_x86_64/[Debug|Release]文件夾。

我還更新了pepper_49 earth例子的Makefile，以試圖得到一些代碼覆蓋率數據，只改變以下行：

VALID_TOOLCHAINS := clang-newlib 
... 
LIBS = ppapi_simple_cpp nacl_io sdk_util ppapi_cpp ppapi pthread compiler_rt 
... 
CFLAGS = --coverage -Wall

當我試圖打造，我得到以下（請請注意，我也嘗試進行64位鏈接，但附加了錯誤的輸出，沒有電流的裝置與正確的輸出來取代它...）：

我做的東西（可能是幾個）令人難以置信的基本這裏錯了，但沒有任何文檔我在一個頭緒來：

構建pnacl編譯-RT正確
讓它如此鏈接，我可以儀器我.nexe文件，並得到一些覆蓋數據。

任何幫助，非常感謝。

要建立正確的，你需要建立一個能與NaCl的工具鏈編譯
要鏈接，一旦與氯化鈉的工具鏈鏈接構建的應罰款（假設你只有跟你主持編譯器即蘋果內置）。儘管在你的例子中註釋了你已經把庫放在64位文件夾中，並且你正在嘗試構建一個32位的例子。

謝謝。我將仔細檢查使用的編譯器，我可能是錯誤的，因爲我沒有觸及大部分make文件。重點2：這不是一個問題，我也試圖64位鏈接（使NACL_ARCH = x86_64），但附加了錯誤的輸出： - /我會改正它，但不會在一個星期附近的PC。 – splrs
