SOLVED Adding mcrypt extension

[Shai]

I need to add the mcrypt extension to a Lamp 7.4 app.

mcrypt was no longer included with PHP since PHP 7.2

I'm presuming I would have to create a custom app to add it to a Lamp 7.4 install. Please confirm or tell me otherwise.

Thanks.

Have you tried installing it on your own? Please see Lamp App - Installing custom PHP extensions

@subven thanks.

I followed the instructions Lamp App - Installing custom PHP extensions. I was not able to get mcrypt installed that way.

Mcrypt is a pecl extension. Pecl is installed. In the app terminal I ran
pecl and it returned Failed loading /app/data/mcrypt/mcrypt.c: /app/data/mcrypt/mcrypt.c: invalid ELF header.

If I run pecl install mcrypt
I get

Failed loading /app/data/mcrypt/mcrypt.c:  /app/data/mcrypt/mcrypt.c: invalid ELF header
WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update

root@4b54a6f7-bd10-4898-a1a8-6c13ffb94a11:/app/data# 

Any ideas?

Thanks.

@Shai the lamp package is currently not setup to deal with pecl extension installation, various required paths are read-only in the app, so this will currently not work.

Not sure if this is something we should support from an app package perspective or as mentioned the better way is to create a custom app. Main concern for me is, how there things get updated/recompiled when we push an lamp update as such.

@nebulon Thanks. I guess this is my chance to create my first custom app.

@nebulon I think it would be helpful to mention in the "Installing custom PHP extensions" portion of the docs that pecl extensions are not supported. It would have saved me some time and frustration.

@nebulon you just run the update command(s)
