解决zlib.h:no such file or directory

今天在linux装Qt库时，出现了
error： zlib.h:no such file or directory
去看了下出错的文件，里面这么一句#include
没这头文件？那就给它呗。
然后去搜索了下zlib.h，发现是属于zlib的。
去下个zlib。
zlib地址：http://www.zlib.net/

然后

zlib标准安装指导：

zlib library files are placed into /usr/local/lib and zlibheader 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]# makeinstall
• 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]# makeinstall
• .../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 willcontain zlib
    • .../zlib-1.2.1]#mkdir /usr/local/zlib
  • follow the given procedureabove, 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 zlibshared lib: libz.so.1.2.1

• for standard zlib installation...
  • add /usr/local/lib to/etc/ld.so.conf, if specified path is not present
  • /etc]# ldconfig
• if zlib was installed with a prefix...
  • add /usr/local/zlib/lib to/etc/ld.so.conf
  • /etc]# ldconfig

再装，ok了。
