General methods for installing software in Linux

Installation example: how to install ImageMagick

 

The installation methods of ImageMagick include rpm and source. The latest version is ImageMagick-6.5.5. Download: http://www.imagemagick.org from this URL

 

Installation steps:

 

1. SSH connection to Linux Server

 

2. Place the downloaded installation file in the appropriate folder. For example, CD/usr/local/src. Or download it directly on the server.

 

3. decompress the download command:

Tar-zxvf ImageMagick-6.5.5-7.tar.gz

 

5. Enter the decompressed folder command:

CD ImageMagick-6.3.5-7

 

6. Configure configuration command:

./Configure

 

Note:

Run./configure -- help to check the configuration parameters. Set the parameters as needed.

 

Generally, image processing must support several common image formats: JPEG, PNG, and GIF.

 

Check the configuration result. If yes, no means not.

 

JPEG V1 -- With-JPEG = Yes

PNG -- With-PNG = Yes

Zlib -- With-zlib = Yes

 

In case of no, run the following command to check whether the corresponding library is installed.

 

Rpm-Qa | grep JPEG // zlib for zlib and PNG for libpng

 

Execution result: libjpeg-6b-33

 

The execution result is indeed a jpeg library installed, but why is it not recognized?

Finally, I checked it online for half a day and found that the libjpeg-devel library must be installed.

Some systems may have been installed by default, so they may not be concerned.

Download the libjpeg-devel library RPM Installation File and install it online.

 

After the installation is complete, configure ImageMagick again. The configuration result is "yes.

 

7. Compile the command:

Make

 

8. Installation command:

Install

 

The ImageMagick installation is complete.
