# webp missing

 * [11 years, 4 months ago](https://wordpress.org/support/topic/webp-missing-1/)
 * To followup, I installed the webp-tools right now (using yum install webp-tools)
   which include cwebp and which also install all missing libraries (meanwhile libjpeg
   and libpng has been installed with first testing of CW Image Optimizer with littleutils,
   libtiff and libgif and their dependencies where missing also.
 * However, yum quit with success and placed cwebp at /usr/bin. I then copied it
   to the eww folder with the other binaries using -custom to prevent overwriting.
   I also changed owner to apache to take sure, everything will work well.
 * However, I still get webp missing.

 * And you’re on a CentOS 7 VPS with DO, right?

 * Looks like CentOS 7 might be shipping with newer versions of libjpeg and libpng
   than what I compile with on CentOS 5. I’ll see what I can figure out.

 * well, that, and EWWW doesn’t support anything older than webp .4+, whereas most
   distros are going to ship with old versions. You can compile it using these commands
   though:
 *     ```
       yum install libpng-devel libjpeg-turbo-devel gcc gcc-c++ make openssl-devel
       wget http://downloads.webmproject.org/releases/webp/libwebp-0.4.2.tar.gz
       tar xvzf libwebp-0.4.2.tar.gz
       cd libwebp-0.4.2
       ./configure
       make && make install
       ```
   
 * After you run ./configure, make sure it says both jpeg and png are supported 
   before you run the last command. Of course, those all need to be run as root,
   or prefixed with sudo.

 * I’m on a CentOS 7 VM, dunno what DO means.
 * Many thanks for your solution, JFYI I found an easier (updateable) similar way
   after unsuccessful checking (somehow all) third party repositories to let yum
   keep webp up to date:
 * yum install libtiff giflib
    wget [http://downloads.webmproject.org/releases/webp/libwebp-0.4.2-linux-x86-64.tar.gz](http://downloads.webmproject.org/releases/webp/libwebp-0.4.2-linux-x86-64.tar.gz)
   tar xvfz libwebp-0.4.2-linux-x86-64.tar.gz
 * Maybe version requirement (webp >=.4.0.0) should be stated in the warning message.

 * DO = Digital Ocean, I thought that’s what you had said on the other thread, but
   I guess that was someone else. Sounds like the stock binaries from google work
   just fine for you, I should have thought of that first. Good luck!
