Question

使用建议的步骤（从根目录）下载并安装jemalloc 4.0.0：

./autogen.sh
make dist
make
make install

已验证安装在我的路径中：

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

使用rbenv 0.4.0，尝试构建ruby 2.2.3并将标志传递给指定here的ruby构建以使用--with-jemalloc选项。构建失败:(如果我只是通过编译器，它会成功。任何想法如何获得rbenv / ruby-build来找到我的jemalloc安装？

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

想出来。在OS X Yosemite上清理了我的第一次尝试，然后下载了jemalloc-4.0.0.tar.bz2。解压缩并根据https://bugs.ruby-lang.org/issues/9113#note-39中的Nobu注释从根目录运行./configure --with-jemalloc-prefix=""。然后只需make和make install。

一旦我验证了jemalloc安装正确，我就可以通过CONFIGURE_OPTS="--with-jemalloc" rbenv install 2.2.3将选项传递给rbenv。

奖励：另一个有助于确定断点的方法是直接下载并解压缩ruby源代码tarball，然后在根目录中运行./configure --with-jemalloc。它将吐出所有构建检查的输出，包括一个用于jemalloc。

使用jemalloc和rbenv编译Ruby 2.2的正确方法是什么？
