Admin/Components Compression Library

[Nap]

[MacOS Catalina 10.15.3]

When I enter Admin -> Components, I get a warning message: Admin action failed: without a PHP compression library extension it is impossible to retrieve a package from the update server. Please enable before downloading zip (.zip file) extension.

Since I'm not sure exactly what's missing, I installed brew install zlib and then built the wrapper from the php-7.3.11 source using:

    cd ./ext/zip
    /usr/local/bin/phpize
    export CC=/usr/local/bin/gcc-10
    export CXX=/usr/local/bin/g++-10
    ./configure --with-php-config=/usr/local/bin/php-config --with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/
    make
    cd modules
    sudo cp zip.so /usr/local/php/

I then added extension=/usr/local/php/zip.so, the ZLIB extension, to the php.ini and restarted the Apache server.

However, the warning/error didn't go away when I returned to the page. Did I install the correct library (homebrew zlib 1.2.11)? Or what else is missing?

(Sorry for the barrage of questions today.)

Zip and Zlib are different libs:

• https://www.php.net/manual/fr/book.zip.php
• https://www.php.net/manual/fr/book.zlib.php

Zlib is not supported.

Thanks Stephane!

Ok, so what I needed to do was to build the zlib php extension for this, not zip.

cd ./ext/zlib
/usr/local/bin/phpize
export CC=/usr/local/bin/gcc-10
export CXX=/usr/local/bin/g++-10
./configure --with-php-config=/usr/local/bin/php-config --with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/
make
cd modules
sudo cp zlib.so /usr/local/php/

In order to build this, brew isntall zlib is still required (not libzip).

No, you need zip extension, not zlib extension.
