libwebp not installed or running

SAJM · 03-08-2022, 09:57 AM

I'm installing a chart and navigation package Opencpn using Slackbuild

I have installed all the dependencies bar 1: webkitgtk

webkitgtk has a dependency: libwebp which I installed

When I install webkitgtk I get the following:

Quote:

checking for jpeglib... yes
checking for libpng... yes
checking webp/decode.h usability... no
checking webp/decode.h presence... no
checking for webp/decode.h... no
configure: error: WebP library (libwebp) not found

Clearly libwebp is not actually installed.

How do I determine the status of the dependency libwebp?

Thanks

You are going to be building that app correct?
If so then you need the dev package for libwebp so it has the header files and includes.

I can't find a dev version on the Webp site

It is recommended that you make these lines your new installation script.

Would you like to make this stuff the install script for this package
and remove the symbolic links ([y]es, [n]o)? y

Removing symbolic links:
removed './usr/lib64/libwebpdemux.so.2'
removed './usr/lib64/libwebp.so'
removed './usr/lib64/libwebpdecoder.so'
removed './usr/lib64/libwebp.so.7'
removed './usr/lib64/libwebpmux.so'
removed './usr/lib64/libwebpdecoder.so.3'
removed './usr/lib64/libwebpmux.so.3'
removed './usr/lib64/libwebpdemux.so'

Creating your new ./install/doinst.sh...

This next step is optional - you can set the directories in your package
to some sane permissions. If any of the directories in your package have
special permissions, then DO NOT reset them here!

Would you like to reset all directory permissions to 755 (drwxr-xr-x) and
directory ownerships to root.root ([y]es, [n]o)? n
