Compile Ruby From Source

下载需要的软件包

假设需要安装的ruby目录为/path/to/ruby_dir

export RUBY_DEST=/path/to/ruby_dir

编译openssl

./config --prefix=$RUBY_DEST  shared
make 
make install

编译libyaml

./configure --prefix=$RUBY_DEST
make
make install

编译pkg-config(如果版本过低需要安装，否则编译ruby会报错Unknown keyword 'URL' in '.$RUBY_DEST.tmp.pc')

./configure --prefix=$RUBY_DEST         \
            --with-internal-glib  \
            --disable-host-tool

如果报错：

gthread-posix.c: In function `g_system_thread_set_name':
gthread-posix.c:1175: error: `PR_SET_NAME' undeclared (first use in this function)
gthread-posix.c:1175: error: (Each undeclared identifier is reported only once
gthread-posix.c:1175: error: for each function it appears in.)

就需要在pkg源码目录下glib/glib/gthread.c添加：

#define PR_SET_NAME    15               /* Set process name */
#define PR_GET_NAME    16               /* Get process name */

然后再继续编译

make && make install

编译ruby

先导入环境变量,否则ruby找不到ssl的链接目录

export LD_LIBRARY_PATH=$RUBY_DEST/lib
export C_INCLUDE_PATH=$RUBY_DEST/include

开始编译ruby

./configure --prefix=$RUBY_DEST --with-opt-dir=$RUBY_DEST
make
make install

编译sqlite3(可选)

测试

$RUBY_DEST/bin/ruby -v #打印版本号，说明安装成功
export PATH=$PATH:$RUBY_DEST/bin
ruby
