ossl_pkey_ec.c: In function ‘ossl_ec_group_initialize’:
ossl_pkey_ec.c:761: warning: implicit declaration of function ‘EC_GF2m_simple_method’
ossl_pkey_ec.c:761: warning: assignment makes pointer from integer without a cast
ossl_pkey_ec.c:816: error: ‘EC_GROUP_new_curve_GF2m’ undeclared (first use in this function)
ossl_pkey_ec.c:816: error: (Each undeclared identifier is reported only once
ossl_pkey_ec.c:816: error: for each function it appears in.)
make[2]: *** [ossl_pkey_ec.o] Error 1
make[2]: Leaving directory `/root/ruby-1.9.3-p194/ext/openssl'
make[1]: *** [ext/openssl/all] Error 2
make[1]: Leaving directory `/root/ruby-1.9.3-p194'
make: *** [build-ext] Error 2
[root@mysql ruby-1.9.3-p194]#

问题原因：

由于redhat新版本默认openssl的配置变更取消了对EC_xx的支持，所以出现该错误。

解决方法：

该问题在ruby网站上已经提交并有了补丁。
参见链接：https://bugs.ruby-lang.org/issues/8384

即修改ext/openssl/ossl_pkey_ec.c代码如下：





gem install安装慢的解决方法：
移除gem 自带的源，默认是

http://rubygems.org/

[root@mysql ~]# gem sources --remove http://rubygems.org/ http://rubygems.org/ removed from sources

2.加入taobao的源
参考网站：https://ruby.taobao.org/

[root@mysql ~]# gem sources --add https://ruby.taobao.org/ https://ruby.taobao.org/ added to sources
[root@mysql ~]# gem source -l
*** CURRENT SOURCES ***
 https://ruby.taobao.org/[/code] 
3.gem安装rail，看速度是否上升
[root@mysql ~]# gem install rail

HEADS UP! Haml 4.0 has many improvements, but also has changes that may break
your application:

* Support for Ruby 1.8.6 dropped
* Support for Rails 2 dropped
* Sass filter now always outputs <style> tags
* Data attributes are now hyphenated, not underscored
* html2haml utility moved to the html2haml gem
* Textile and Maruku filters moved to the haml-contrib gem

修改Gemfile才能顺利安装bundle install --without development test rmagickpostgresql sqli

[root@mysql redmine-2.5.3]# ls

gem install 时报错，no such file to load -- zlib

通过gem 安装mysql库时，报告
#gem install mysql
ERROR:  Loading command: install (LoadError)
no such file to load -- zlib
ERROR:  While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand

解决办法是：
进入ruby源码文件夹
安装ruby自身提供的zlib包
#cd ext/zlib
#ruby ./extconf.rb
#make
#make install
