使用jemalloc和rbenv編譯Ruby 2.2的正確方法？

Question

下載並使用他們推薦的步驟（從根目錄）安裝jemalloc 4.0.0：

./autogen.sh 
make dist 
make 
make install 

驗證安裝在我的道路：

$ls /usr/local/bin | grep je 
    jemalloc-config 
    jemalloc.sh 
    jeprof 

使用rbenv 0.4.0，試圖建立紅寶石2.2.3並通過標誌紅寶石建立如指定here使用--with-jemalloc選項。構建失敗:(如果我只是通過編譯器，它成功。任何想法如何獲取rbenv /紅寶石打造找到我jemalloc安裝？

$CC="/usr/local/Cellar/gcc5/5.2.0/bin/gcc-5" CONFIGURE_OPTS="--with-jemalloc" rbenv install 2.2.3

想通了。整理了我的第一次嘗試，然後在OS X優山美地，下載jemalloc-4.0.0.tar.bz2來代替。打開包裝，並基於在https://bugs.ruby-lang.org/issues/9113#note-39 Nobu餐廳的音符根目錄下​​運行./configure --with-jemalloc-prefix=""。然後，只需make和make install。

一旦我覈實jemalloc已正確安裝，我能夠在選項傳遞給rbenv與CONFIGURE_OPTS="--with-jemalloc" rbenv install 2.2.3。

獎勵：另一個有助於確定中斷點的方法是直接下載並解壓縮ruby源tarball，然後在根目錄內運行./configure --with-jemalloc。它會吐出所有構建檢查的輸出，其中一個用於jemalloc。
