#47 楼 @luikore 搞定啦。。。自己手动改了 makefile，然后将 mri 目录下文件的 errno 代码全部删除掉，上传到我的 github，gem install bcrypt-ruby, github:xxxx'就可以了。。 现在就是用annotate`的时候报这个错误

You don't have bcrypt-ruby installed in your application. Please add it to your Gemfile and run bundle install
Unable to annotate user.rb: can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.0. Make sure all dependencies are added to Gemfile.
Nothing annotated.

这个错误怎么解决

#44 楼 @luikore = = 网上买个装系统的 u 盘还几天才到，我又仔细看了下，最根本的问题就肯定就是一句/usr/bin/ld: errno: TLS definition in /lib/x86_64-linux-gnu/libc.so.6 section .tbss mismatches non-TLS reference in wrapper.o 要解决的话应该就是makefile，我errno.h应该没什么问题了. 你再确定一下$CFLAGS = "-I/usr/include #{$CFLAGS}" # 加这行就可以了这句话对不对。。 网上说编译的时候加 -include /usr/include/errno.h即可，我不太懂这句话是什么意思

#44 楼 @luikore = = 好纠结的问题，重装系统。。。好吧。。

#42 楼 @luikore 确实，我在 errno.h 里面找到了extern int errno，然后去掉这一行自己定义错误变量，现在报错信息变了

wrapper.c: 在函数‘crypt_gensalt_rn’中:
wrapper.c:208:3: 错误： ‘errno’未声明(在此函数内第一次使用)
wrapper.c:208:3: 附注： 每个未声明的标识符在其出现的函数内只报告一次

但是代码这一个部分又不知道该怎么处理了

__set_errno(EINVAL);

#39 楼 @luikore 还是报刚才这个错误，官方 3.10 版本也是改动了这一部分去掉警告信息，加上你刚才改的，就变成了

require "mkmf"
  have_header('ruby/util.h')
  $CFLAGS = "-I/usr/include #{$CFLAGS}"
  dir_config("bcrypt_ext")
  create_makefile("bcrypt_ext")

然后 gem build bcrypt-ruby.gemspec

Successfully built RubyGem
Name: bcrypt-ruby
Version: 3.1.0
File: bcrypt-ruby-3.1.0.gem

然后 gem install -l bcrypt-ruby-3.1.0.gem 报错：

linking shared-object bcrypt_ext.so
/usr/bin/ld: errno: TLS definition in /lib/x86_64-linux-gnu/libc.so.6 section .tbss mismatches non-TLS reference in wrapper.o
/lib/x86_64-linux-gnu/libc.so.6: 无法读取符号: 错误的值
collect2: 错误： ld 返回 1
make: *** [bcrypt_ext.so] 错误 1

#37 楼 @luikore 在.rvm 下面搜索也是这样。。。网上说是要在 makefile 里面加上 - include /usr/include/errno.h , 但是每次 gem install，gem 里面的包就会重置。。改 makefile 也没用啊

#35 楼 @luikore 用搜索搜的文件系统。。。

#33 楼 @luikore bcrypt_ext.so找不到。。。 改C_INCLUDE_PATH是担心我的 C 环境变量不对，可能 gem 中的#include<errno.h>指向的不是我修改的，然后我就将环境变量重新指向/usr/include，果然前面的定义问题就没了

#31 楼 @luikore 昨天安装的bcrypt-ruby还是用不了，我修改了下C_INCLUDE_PATH，报错信息改变了，现在是另外一个。。这个不知道怎么解决了。

/usr/bin/ld: errno: TLS definition in /lib/x86_64-linux-gnu/libc.so.6 section .tbss mismatches non-TLS reference in wrapper.o
/lib/x86_64-linux-gnu/libc.so.6: 无法读取符号: 错误的值

#28 楼 @luikore 我晕。。又这么长一串。。学习了

#26 楼 @luikore 哈哈，你这是不求甚解的精神啊，留个邮箱或者 qq 吧，以后还有问题要请教您呢

#24 楼 @luikore 哈哈，安装成功了就不管了，现在没钱换电脑，用的还是linuxmint，有钱换 mac 了环境应该会稳定很多。。。你也是 mac 下虚拟机装的 ubuntu 吗？

#22 楼 @luikore 项目里面 bundle install 也 ok 了，我晕。。这个真心不解是什么意思。。

#19 楼 @luikore 我靠。。受不了了。我直接在github上下了个bcrypt-ruby

• 解压，直接gem build bcrypt-ruby.gemspec
• 然后直接 gem install --local bcrypt-ruby.gem

就直接安装成功了

#17 楼 @luikore ERROR: Gemspec file not found: bcrypt-ruby.gemspec 现在 make install 成功了，在哪个目录 gem build ?

#14 楼 @luikore 我手动改掉所有的 EINVAL 和 ERANGE 可以在源代码目录下 make，然后 make install，然后我不就不知道该怎么办了，gem list 里面还没有 bcrypt-ruby

#10 楼 @luikore 这个什么都没有显示啊。。

#8 楼 @luikore zh_CN.UTF-8

#5 楼 @luikore 好诡异，那个 EINVAL 我自己在 errno.h 定义为 22 就可以了，然后报另外一个错

compiling crypt_blowfish.c
crypt_blowfish.c: 在函数‘BF_crypt’中:
crypt_blowfish.c:585:3: 错误： ‘ERANGE’未声明(在此函数内第一次使用)

这个我再在errno.h中定义 ERANGE 为 32 就死活不出来，那个 c 还 include 了 string.h，我就到 string.h 里面定义 ERANGE 也没用。。。

#1 楼 @luikore 3.0.1 源码里面有 errno.h，但是我系统的 errno.h 好像跟 kernel2.6 不一样，我是 kernel3.8，能否发一份 errno.h 到 [email protected] , thanks !

同这个问题。。

歪个楼。。纠正下是workaround不是workround ...

#12 楼 @southwolf 楼上不对。

page.should have_title("your_title")   #it's true

下面怎么讨论讨论就歪楼了。。 这个问题是在spec_helper.rb中加入一段代码：

config.include Capybara::DSL

要翻墙，少年。。

#9 楼 @outman 看下这个吧，http://weloveiconfonts.com，挺好折腾的

ok 啦.. 还需要gem install xxx 安装一些相关依赖就好了
