Question

我在Arch Linux上遇到此错误，尽管系统中存在mysql.h。有谁知道如何解决这个问题？这里有一些命运：

$ find /usr -name mysql.h
/usr/include/mysql/mysql.h
$ echo $PATH
/home/chris/.rvm/gems/ruby-1.8.7-p302@bogen/bin:/home/chris/.rvm/gems/ruby-1.8.7-p302@global/bin:/home/chris/.rvm/rubies/ruby-1.8.7-p302/bin:/home/chris/.rvm/bin:/bin:/usr/bin:/usr/lib:/sbin:/usr/sbin:/home/chris/bin:/home/chris/lib:/usr/share/eclipse:/opt/kde/bin:/usr/bin/perlbin/site:/usr/bin/perlbin/vendor:/usr/bin/perlbin/core:/opt/qt/bin:/usr/include:/usr/local/include:/opt/ruby1.8/bin:/usr/local/bin:/usr/local/sbin:/usr/bin/vendor_perl:/usr/bin/core_perl

以下是gem install mysql

的确切输出

$ which ruby

$ gem install mysql

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
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib

    --without-make-prog

    --curdir
    --ruby=/home/chris/.rvm/rubies/ruby-1.8.7-p302/bin/ruby
    --with-mysql-config
    --without-mysql-config


Gem files will remain installed in /home/chris/.rvm/gems/ruby-1.8.7-p302@bogen/gems/mysql-2.8.1 for inspection.

由于这是Arch linux，因此没有像Ubuntu或CentOS那样的开发包。我尝试过的上述命令的变化包括：

gem install mysql -- --with-mysql-include=/usr/include/mysql --with-mysql-config
gem install mysql -- --with-mysql-include=/usr/include/mysql
gem install mysql -- --with-mysql-include=/usr/include

一切都无济于事。不幸的是，我能够找到的这个错误的其他报告要么与Mac OS有关，要么在其他Linux发行版上没有devel包。由于头文件在我的情况下并且似乎在标准位置，我不知道接下来要尝试什么。任何提示都会非常感激。

Answer 1

这也可能是由于未安装GCC造成的，因为这是检查的完成方式。

Answer 2

这个对我有用。

yum install libodb-mysql-devel.i686 mysql-devel.i686 soci-mysql-devel.i686

gem安装mysql检查mysql.h ...没有
