note 125421 added to image.installation

If you are using and old Ubuntu version (15.04) and want to compile PHP 7.4 from source with GD and JPEG support, you will probably get an error like this : --------- checking for libjpeg... no configure: error: Package requirements (libjpeg) were not met: No package 'libjpeg' found --------- No longer able to "apt-get" the libjpeg package to a more recent version, the only solution was to: ----- $> wget http://www.ijg.org/files/jpegsrc.v9c.tar.gz $> tar xzf jpegsrc.v9c.tar.gz $> cd jpeg-9c $> ./configure | make | make install ----- After this, I was able to run the configure script without errors and compile and install PHP 7.4 Hope this helps. ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.172 (proxied: 94.62.246.65) ---- Manual Page -- http://php.net/manual/en/image.installation.php Edit -- https://master.php.net/note/edit/125421 Del: integrated -- https://master.php.net/note/delete/125421/integrated Del: useless -- https://master.php.net/note/delete/125421/useless Del: bad code -- https://master.php.net/note/delete/125421/bad+code Del: spam -- https://master.php.net/note/delete/125421/spam Del: non-english -- https://master.php.net/note/delete/125421/non-english Del: in docs -- https://master.php.net/note/delete/125421/in+docs Del: other reasons-- https://master.php.net/note/delete/125421 Reject -- https://master.php.net/note/reject/125421 Search -- https://master.php.net/manage/user-notes.php
