ruby - 用jemalloc和rbenv编译Ruby 2.2的正确方法？

使用建议的步骤(从根目录)下载并安装了jemalloc 4.0.0:

./autogen.sh
make dist
make
make install

经过验证的安装在我的道路上:

    $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并将标志按指定的here传递给ruby构建以使用--with-jemalloc选项。构建失败:(如果我只是通过编译器，它将成功。关于如何获取rbenv/ruby-build来找到我的jemalloc安装的任何想法？

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

最佳答案

弄清楚了。整理完我的第一个尝试，然后在OS X Yosemite上进行了整理，改为下载jemalloc-4.0.0.tar.bz2。根据Nobu在https://bugs.ruby-lang.org/issues/9113#note-39中的注释，将其解压缩并从根目录中运行./configure --with-jemalloc-prefix=""。然后只是make和make install。

确认正确安装了jemalloc后，便可以使用CONFIGURE_OPTS="--with-jemalloc" rbenv install 2.2.3将选项传递给rbenv。

奖励:有助于确定断点的另一件事是直接下载并解压缩ruby源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的检查。
