为了在 mac 上构建 ruby 1.9,我必须安装 gcc 4.6。 Rails 和一堆其他的 gem 构建得很好。安装 mysql 或 mysql2 让我心痛不已。
rubygems> env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include --with-mysql-config=/usr/local/mysql/bin/mysql_config Building native extensions. This could take a while... ERROR: Error installing mysql2: ERROR: Failed to build gem native extension.

mysql.h is missing. please check your installation of mysql and try again.

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.
Provided configuration options:
--with-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib

Gem files will remain installed in /Users/ff/.rvm/gems/ruby-1.9.3-p0/gems/mysql2-0.3.11 for inspection.
Results logged to /Users/ff/.rvm/gems/ruby-1.9.3-p0/gems/mysql2-0.3.11/ext/mysql2/gem_make.out
当我查看 mkmf.log 文件时,我看到:

gcc-mp-4.6: error: i386: No such file or directory
gcc-mp-4.6: error: unrecognized option '-arch'
checked program was:
/* begin */
1: #include "ruby.h"
2:
3: #include <mysql.h>
/* end */
所以基本上似乎不支持 -arch 标志。任何人都知道这些编译选项在哪里提供,以便我可以删除此标志?或任何其他解决方案....谢谢
最佳答案
我尝试了这里发布的所有解决方案,但并不走运。我通过自制软件重新安装了 mysql 几次,但仍然没有运气。然后我看到了一篇包含解决方案的博文。
我编辑了 /usr/local/Cellar/mysql/5.6.12/bin
中的 mysql_config
文件并删除了 W-编译器选项 -Wno-
和 cflags
和 cxxflags
的 null-conversion-Wno-unused-private-field
。
这解决了 gem install mysql2
的问题。
