I have a PHP|7.4 Linux App Service that needs good-old mcrypt from pecl.
I have pear and pecl provided by the existing installation.
When I do
pecl install mcrypt
I get a long run of 'configure' that ends in
checking for mcrypt support... yes, shared
configure: error: mcrypt.h not found. Please reinstall libmcrypt.
Other times, I've gotten 'config.h' not found.
Does anybody know how to install mcrypt (1.0.4) I know that it's deprecated, and we shouldn't use it, but we have legacy needs.
Thanks
