yum install zlib-devel

2 集成zlib库到Ruby环境

进入到相关目录

# cd ruby-2.3.8/ext/zlib
# ruby extconf.rb
checking for deflateReset() in -lz... yes
checking for zlib.h... yes
checking for crc32_combine() in zlib.h... yes
checking for adler32_combine() in zlib.h... yes
checking for z_crc_t in zlib.h... yes
creating Makefile
# make
linking shared-object zlib.so
# make install
/bin/install -c -m 0755 zlib.so /usr/local/ruby/lib/ruby/site_ruby/2.3.0/x86_64-linux
