Hello. I am developing an Apache module that, upon receiving an HTTP request, reads a file in a custom language where a series of request handlers are declared. Once the file has been parsed and a handler has been found, the
source code it contains is obtained, which is in PHP; and it tries to load the PHP Embed header, but I'm getting this error message: > apache2: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/rst.load: Cannot load /usr/lib/apache2/modules/mod_rst.so into server:

php-embed and
libphp-embed packages, maintained by the Debian PHP and PHP PEAR Maintenance teams, and as it still didn't work, I've downloaded and compiled the PHP 8.4.1 source code with
the --enabled-embed flag, but I still get the same error. I must add that, both with the php-embed and
libphp-embed packages, and with the source code compiled by myself, I have compiled a basic program with the PHP Embed library and I have had no problems, the output is correct,
the basic example comes from this repository: https://github.com/KapitanOczywisty/PHP_embed_docs/blob/main/embed.md. I have searched a lot, although I probably have not found the correct search terms, since the words “Apache, module and PHP” together flood the results, surely hiding this specific case. I could conclude that the PHP
Embed API works correctly, except when I try to use it in an Apache module. I understand that you could tell me to go to the PHP channels, you are not wrong, but I thought it appropriate to expose my problem here in case someone has had this experience. Thank you very much for reading, greetings. |
