Azure linux web app service enable webP image support (PHP Version 7.4.28)?

Question

Azure linux web app service enable webP image support (PHP Version 7.4.28)?

Douglas Fabiano de Oliveira 6

Hi everyone!

I'm facing a problem when trying to convert a JPG image to WEBP using the imagewebp function in PHP. The error response is "Call to undefined function imagewebp()".

After a lot of research, I see that it's necessary to enable the WebP Support in my linux web app. This image shows all the GD extension that I have enabled. Do you know how can I enable the WebP Support to make the function imagewebp() work?

I execute the command below in SSH/kudu that I found in google, but without success :/

Command:
apt-get update && apt-get install -y libwebp-dev && docker-php-ext-configure gd --with-freetype-dir=/usr --with-png-dir=/usr --with-jpeg-dir=/usr --with-webp-dir=/usr --with-vpx-dir=/usr && docker-php-ext-install gd

Error:
/usr/src/php/ext/gd/libtool: line 1283: libgd/gd.loT: No such file or directory
mkdir libgd/.libs
mkdir: cannot create directory 'libgd/.libs': No such file or directory
make: *** [Makefile:197: libgd/gd.lo] Error 1

Thank you very much for any directions ;)

Thanks for reaching here! If I understand right you want to enable the PHP extensions WebP and GD library on the App Service linux,
Could you try to use the below startup script.

apt-get update apt-get install -y libwebp-dev libjpeg62-turbo-dev libpng-dev libxpm-dev libfreetype6-dev docker-php-ext-configure gd --with-gd --with-webp --with-jpeg-dir --with-png-dir --with-zlib-dir --with-xpm-dir --with-freetype-dir --enable-gd-native-ttf docker-php-ext-install gd apache2ctl -D FOREGROUND

Hi @SnehaAgrawal-MSFT

Thank you very much for trying to help with this problem. I execute this commands in SSH and the WebP extension continue not enabled.

When I execute the line "docker-php-ext-configure gd --with-gd --with-webp --with-jpeg-dir --with-png-dir --with-zlib-dir --with-xpm-dir --with-freetype-dir --enable-gd-native-ttf", I received this warning:

WARNING: unrecognized options: --with-jpeg-dir --with-png-dir --with-zlib-dir --with-xpm-dir --with-freetype-dir --enable-gd-native-ttf

I changed this line to below because I think my PHP version changed something:

docker-php-ext-configure gd --enable-gd --with-webp --with-jpeg --with-xpm --with-freetype

But, when I run "docker-php-ext-install gd", I still receiving this error at the end of the execution:

/usr/src/php/ext/gd/libtool: line 1283: libgd/gd.loT: No such file or directory
mkdir libgd/.libs
mkdir: cannot create directory 'libgd/.libs': No such file or directory
make: [Makefile:197: libgd/gd.lo] Error 1

Just to complete the instructions, I run the command "apache2ctl -D FOREGROUND" and after that I call the phpinfo and webP still not enabled.

After this, I came across at this post:

https://livtutor.com/enable-webp-support-php-7/

I execute this instructions and achieve my goals to use the imagewebp function. If you know what is the problem that happens with the commands and have any suggestion how to run the imagewebp native, please let me know.

Thank you for the time!

@Douglas Fabiano de Oliveira

You can install/enable webP (with gd) support through startup command/script.

Using below command was able to get it running:

apt update apt install libfreetype6-dev libjpeg62-turbo-dev libwebp-dev libpng-dev docker-php-ext-configure gd --with-webp --with-jpeg --with-freetype docker-php-ext-install gd

As you can see from php -r "var_dump(gd_info());" output, webP support is enabled once you follow above steps:

array(14) {
["GD Version"]=>
string(26) "bundled (2.1.0 compatible)"
["FreeType Support"]=>
bool(true)
["FreeType Linkage"]=>
string(13) "with freetype"
["GIF Read Support"]=>
bool(true)
["GIF Create Support"]=>
bool(true)
["JPEG Support"]=>
bool(true)
["PNG Support"]=>
bool(true)
["WBMP Support"]=>
bool(true)
["XPM Support"]=>
bool(false)
["XBM Support"]=>
bool(true)
["WebP Support"]=>
bool(true)
["BMP Support"]=>
bool(true)
["TGA Read Support"]=>
bool(true)
["JIS-mapped Japanese Font Support"]=>
bool(false)
}

Hello @SnehaAgrawal-MSFT !

Thanks, but I'm still getting the error cannot create directory 'libgd/.libs': No such file or directory when I execute the last command docker-php-ext-install gd and the webP support still in ["WebP Support"]=>bool(false) when I run the command php -r "var_d ump(gd_info());".

If you want to reproduce this error, please follow this steps:

1 - In azure portal, create a new app service plan with Name=Appsvcplan-webp, Region=Central US, Operational System=Linux, Princing Tier=Basic B1;

2 - Create a app service with Name=webappwebp, Publish=Code, Runtime stack=PHP 7.4, Operational System=Linux, Region=Central US, Linux Plan=Appsvcplan-webp;

3 - Open the url https://webappwebp.scm.azurewebsites.net/, open SSH and type the commands:

a. apt update
b. apt install libfreetype6-dev libjpeg62-turbo-dev libwebp-dev libpng-dev
c. docker-php-ext-configure gd --with-webp --with-jpeg --with-freetype
d. docker-php-ext-install gd

You will see the error cannot create directory 'libgd/.libs': No such file or directory - make: * [Makefile:197: libgd/gd.lo] Error 1** when executing the last command and the webp support is not enabled when I type the command php -r "var_d ump(gd_info());".

Do you know if I missing something?

*Sorry for the command "var_d ump", if I write all together my comment is not posted :/

Best regards.

You have mistake in your steps u need next

open for edit startup.sh (can do it on console) (this file)

and add to this file next (for php8.1)

apt-get update && apt-get install -y libfreetype6-dev \
                libjpeg62-turbo-dev \
                libpng-dev \
                libwebp-dev \
        && docker-php-ext-configure gd --with-freetype --with-webp  --with-jpeg
docker-php-ext-install gd

restart u azure web app

User's image

and after restart, go to console and run command php --ri gd and u can look this User's image

after this u must be happy )
