Error message configure: error: ZLib not installed when installing libpng in Centos 6.2

Centos 6.2 installation libpng error message configure: error: ZLib not installed

When compiling libpng-1.5.8.tar.gz, an error is reported. configure: error: ZLib not installed. I used the following package for compilation.

Zlib-1.2.6.tar.gz libpng-1.5.8.tar.gz

Solution:

1. Enter the source file directory of the zlib-1.2.6, execute the command make clean, clear zlib;

2. reconfigure./configure. Do not use the -- prefix parameter later;

3. Compile make & install make install;

4. Go to the libpng-1.5.8 directory and run the command./configure -- prefix =/usr/local/libpng;

5. Compile make & install make install;

6. The installation is successful;
