thumbnail+gallery not working on fresh install

[sksbir]

Hi.
Has I'm sure the only one to have this problem, I think it's a configuration problem. apache and PHP are installed on defaults path too (coming with fedora23 distribution ) but not configured nor enabled.
My first aim is to get more info about the problem. httpd.conf in debug mode didn't gave me any clue.

Steps to reproduce

1. Fresh manual installation of owncloud 8.2.4, has described here : https://doc.owncloud.org/server/8.2/admin_manual/installation/source_installation.html ( tried again with owncloud 9.0.2 : same )
2. Lauch installation wizard, and successfully access to my admin home page
3. take a look in newly installed "Photos" folder ( the one with 3 jpg inside : Paris, San Francisco, Squirrel )

Expected behaviour

images should be shown has thumbnail in the file list and also be shown in the gallery view.

Actual behaviour

thumbnail isn't shown (just the mimetype image icon) in the file list and the gallery view simply states error creating preview, removing it from preview
NO "thumbnail" folder created in Photo folder, even after browsing from explorer.

Server configuration

• Fedora 23 X64
• Apache 2.4.20 , compiled on custom path ( /envperso/Apache_run )
• MariaDB : manual installation ( from mariadb-10.1.13-linux-glibc_214-x86_64.tar.gz ) on custom path ( /envperso/Mariadb/mysql )
• PHP 7.0.6, compiled on custom path ( /envperso/Php_run )
• owncloud : Tested with 8.2.4 and 9.0.2 , fresh install on /envperso/OC_docroot, /envperso/OC_data specified has data path in installation wizard.
• Activated app : the ones from fresh install.

Sounds like a problem with missing libraries. Check the result of phpinfo() under GD. It should list JPEG as a supported format.

@oparoz : You point it out ! Problem is now solved for thumbnails :

• added '--with-jpeg-dir=/usr/lib64' \ to my config.nice from php installation folder
• compiled php again ( with mandatory "make clean")
• restarted apache

Usefull link : http://stackoverflow.com/questions/7167860/compiling-php-with-gd-and-libjpeg-support

A little suggestion : has png thumbnail works without libjpeg (tested before recompiling), what about insert a png file in "Photo" folder ( I mean .. in default owncloud distribution and installation ) ? People would have a more obvious clue when problem like mine occurs...

Out of that, gallery ( I mean the full page slideshow, not the photo collection ) still not works, it still shows simply states error creating preview, removing it from preview.
No log in owncloud.log, even in "full" mode....

Should I create an other issue ? ( has we can state now that source of the problem is not the same... )

[sksbir]

Everything is working well now. Slideshow was just blocked by uBlock Origin on my browser.
The first thumbnail error let me though there was also a server error here.
Thanks again for your reply.

Ah, good news :)
