installation procedure openJpeg

[Resnow]

Hi,

I have lot of difficulties for installing OpenJpeg on my Centos 7 machine.
I am trying to follow this procedure : https://wiki.orfeo-toolbox.org/index.php/JPEG2000_with_GDAL_OpenJpeg_plugin  in order to use a python script which needs Gdal and OpenJpeg.

I downloaded OpenJpeg from this link : https://github.com/uclouvain/openjpeg/releases/tag/v2.3.0

on the wiki.orfeo-toolbox page, It is written "

Once you have finished the configure step of CMake, run :

make 
make install



here are the commands i used for the configuration

tar xvf /path/to/openjpeg-v2.3.0-linux-x86_64.tar.gz
cd openjpeg-v2.3.0-linux-x86_64
sudo ./configure

but the outpout of the last command is :
sudo: ./configure: command not found


I also tried the steps described here : https://github.com/uclouvain/openjpeg/blob/master/INSTALL.md
but I don't really understand where i have to create the "build" folder and there is no reference to the OpenJpeg package dowloaded ...

Please Help me, I missed something ? 

thanks a lot for your help.

Resnow,

first you must have installed the CMAKE program. Try 'cmake --version' to test whether it exists

on your system.

If not, you must download it from

 http://www.cmake.org

Calling 'configure' is useless, because CMAKE does not know 'configure'.

You can use the following shell script 'cmake-openjpeg.sh' for a test installation:

```

#!/bin/sh
cmake -DBUILD_DOC:bool=off -DBUILD_PKGCONFIG_FILES:bool=on -DCMAKE_BUILD_TYPE:string="Release"  -DBUILD_JAVA:bool=off

-DBUILD_SHARED_LIBS:bool=on -DCMAKE_INSTALL_PREFIX=/usr/local/opj2 ..

If you have a '/usr/lib64' directory you should add '-DOPENJPEG_INSTALL_LIB_DIR=lib64'

```

1. tar xvf openjpeg-xyz.tar.gz

2. cd openjpeg-xyz

3. mkdir BUILD

4. cp FROM_ANYWHERE/cmake-openjpeg.sh .

5. cd BUILD

6. cp ../cmake-openjpeg.sh .

7. ./cmake-openjpeg.sh

8. In case there is no error:

    make

9. In case there is no error:

    make install 1> installed.to

Then you can inspect '/usr/local/opj2' to see what has been installed.

Usually you can find in the LIB/LIB64 directory a 'pkgconfig' directory.

CMAKE does NOT know the command 'make uninstall'. Therefore you

you should either use a separate directory e.g. '/usr/local/opj2' ; or inspect

the file 'installed.to'.

I have a slackware64 system. So I use the directory '/usr/local/opj2' and have

added the line '/usr/local/opj2/lib64' in the file '/etc/ld.so.conf'.

Resnow,

I have missed something.

The archive 'openjpeg-v2.3.0-linux-x86_64.tar.gz' is NOT a source archive. It is compiled archive:

```

szukw000: tar xvf openjpeg-v2.3.0-linux-x86_64.tar.gz

openjpeg-v2.3.0-linux-x86_64/lib/libopenjp2.so
openjpeg-v2.3.0-linux-x86_64/lib/pkgconfig/libopenjp2.pc
openjpeg-v2.3.0-linux-x86_64/lib/libopenjp2.a
openjpeg-v2.3.0-linux-x86_64/lib/openjpeg-2.3/OpenJPEGConfig.cmake
openjpeg-v2.3.0-linux-x86_64/lib/openjpeg-2.3/OpenJPEGTargets.cmake
openjpeg-v2.3.0-linux-x86_64/lib/openjpeg-2.3/OpenJPEGTargets-release.cmake
openjpeg-v2.3.0-linux-x86_64/lib/libopenjp2.so.2.3.0
openjpeg-v2.3.0-linux-x86_64/lib/libopenjp2.so.7
openjpeg-v2.3.0-linux-x86_64/bin/opj_dump
openjpeg-v2.3.0-linux-x86_64/bin/opj_compress
openjpeg-v2.3.0-linux-x86_64/bin/opj_decompress
openjpeg-v2.3.0-linux-x86_64/include/openjpeg-2.3/opj_stdint.h
openjpeg-v2.3.0-linux-x86_64/include/openjpeg-2.3/opj_config.h
openjpeg-v2.3.0-linux-x86_64/include/openjpeg-2.3/openjpeg.h
 ```

If you want to use a source archive you must download 'openjpeg-v2.3.0.tar.gz'.

Then and only then you should follow the above mentioned advices.
