ruby-on-rails - 无法在 OS X Yosemite 上构建 puma gem

Question

(修订)问题:

在我的 OS X Yosemite (10.10.1) 系统上安装 puma gem 需要什么？我已经用尽了很多方法(我有 XCode 工具，我有 OpenSSL)，但是在尝试构建 native 扩展时它仍然失败。

问题

在我的 OS X 系统上，当我这样做时:

$ gem install puma

我得到:

Building native extensions.  This could take a while...
ERROR:  Error installing puma:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

        --with-ssllib
        --without-ssllib
        --with-ssleay32lib
        --without-ssleay32lib

extconf failed, exit code 1

Gem files will remain installed in /Users/home/sandbox/usr/lib/ruby/gems/2.1.0/gems/puma-2.10.2 for inspection.
Results logged to /Users/home/sandbox/usr/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-14/2.1.0/puma-2.10.2/gem_make.out

环境

我怀疑 gem install无法找到 SSL header 和/或库。这是我的系统上的内容(注意 ~/sandbox/usr 是我的“沙箱”目录，包含我的 Ruby on Rails 开发的所有可执行文件、库、头文件等)。请注意，“ssl.h”确实定义了 SSL_CTX_new():

$ which openssl
~/sandbox/usr/bin/openssl
$ openssl version
OpenSSL 1.0.1j 15 Oct 2014
$ openssl version -d
OPENSSLDIR: "/Users/home/sandbox/usr/ssl"
$ find ~/sandbox/usr -name "*libssl*" -print
~/sandbox/usr/lib/libssl.a
$ find ~/sandbox/usr -name "*.h" -exec grep SSL_CTX_new {} /dev/null \;
~/sandbox/usr/include/openssl/ssl.h:SSL_CTX *SSL_CTX_new(const SSL_METHOD *meth);

此外，这里是 ruby​​ 的编译方式。 $INSTALL_DIR 是 ~/home/sandbox:

./configure --prefix=$(INSTALL_DIR) --enable-shared --disable-install-doc --with-opt-dir=$(INSTALL_DIR) --with-openssl-dir=$(INSTALL_DIR)/bin; where INSTALL_DIR is ~/sandbox/usr. 

问题

我是否只是缺少构建过程的一些配置标志？我或多或少地随机尝试了一堆标志:

$ gem install puma -- --with-openssl-dir=/Users/home/sandbox/usr/ssl
$ gem install puma -- --with-ssllib=/Users/home/sandbox/usr/lib/libssl.a 
$ gem install puma -- --with-ssl=/Users/home/sandbox/usr/bin/openssl
$ gem install puma -- --with-ssl=/Users/home/sandbox/usr/bin
$ gem install puma -- --with-opt-dir=/Users/home/sandbox/usr

但在每种情况下都出现相同的错误。有人能告诉我我错过了什么吗？

带有错误的 mkmf.log 文件如下所示(为了可读性添加了换行符):

conftest.c:13:57: error: use of undeclared identifier 'SSL_CTX_new'

int t(void) { void ((*volatile p)()); p = (void ((*)()))SSL_CTX_new; return 0; }

当我浏览沙箱目录树时，唯一定义 SSL_CTX_new 的头文件是 ~/sandbox/include/openssl/ssl.h .似乎没有包含该文件，我目前不知道为什么。

对于在使用 puma 和 openssl 时遇到问题的人，尤其是在 Mac OS 10.11 (El Capitan) 中，添加一些标志将为您节省数小时和数小时的心痛:

gem install puma -- --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib
