Linux下zlib的安装

安装zlib
our configuration
  • install to : /usr/local
  • module types : dynamically and staticly loaded modules, *.so and *.a  
zlib标准安装指导：

zlib library files are placed into /usr/local/lib and zlib header files are placed into /usr/local/include, by default.

  • build static libraries
    • .../zlib-1.2.1]# ./configure
    • .../zlib-1.2.1]# make test
    • .../zlib-1.2.1]# make install
  • build shared libraries
    • .../zlib-1.2.1]# make clean
    • .../zlib-1.2.1]# ./configure --shared  
    • .../zlib-1.2.1]# make test
    • .../zlib-1.2.1]# make install
  • .../zlib-1.2.1]# cp zutil.h /usr/local/include
  • .../zlib-1.2.1]# cp zutil.c /usr/local/include
  • /usr/local/lib should now contain...
    libz.a
    libz.so -> libz.so.1.2.1
    libz.so.1 -> libz.so.1.2.1
    libz.so.1.2.1
  • /usr/local/include should now contain...
    zconf.h
    zlib.h
    zutil.h
  • 可选择的zlib非标准安装指导：
    • create the directory that will contain zlib
      • .../zlib-1.2.1]# mkdir /usr/local/zlib
    • follow the given procedure above, except
      • .../zlib-1.2.1]# ./configure --prefix=/usr/local/zlib
更新软连接：update the run-time linker

/etc/ld.so.cache will need to be updated with the new zlib shared lib: libz.so.1.2.1

  • for standard zlib installation...
    • add /usr/local/lib to /etc/ld.so.conf.d/*conf if specifie path is not present
    • /etc]# ldconfig
    • 如果还是不行的话，则在/lib下建立一个libz.so.1.2.1的软链接名字为libz.so
  • if zlib was installed with a prefix...
    • add /usr/local/zlib/lib to /etc/ld.so.conf
    • /etc]# ldconfig
