php-i2c-extension's Issues

Installation

Hello, I am able to get the extension installed and use it to communicate with a DAC module, however, it only works when using the VS Code built-in web server (Debian 10). When I try to use it with Apache, the device fails to load: "Uncaught Error: Call to undefined function i2c_open()..." I noticed that the debugging process is runnint as root whereas the Apache server is running as www-data. I tried changing the owner of /dev/i2c_1 to www-data:www-/*data, but still no joy.

Also, I am not able to install the PHP library with composer. It fails with: "Failed opening required 'tasoft/php-i2c-extension' (include_path='.:/usr/share/php')

I'm not sure how /usr/share/php is involved with this...

i2c_open("/dev/i2c-0") returns false

I installed this software normally and set php.ini. In addition, I have given permissions on /dev/i2c-0.
However, i2c_open("/dev/i2c-0") returns false. Please tell me what you can think of.
If you change i2c.c as follows, it will succeed.

// int fd = open(devPath, O_RDWR);
int fd = open("/dev/i2c-0", O_RDWR);

php 8.1

Hi
When I run make I get a lot of errors and it will not build.
Should this work on php 8.1?
And yes I did install php8.1-dev

Installation

Hello,

Pi 3B+, new install of PHP.
Following the install, when I try to run phpize, it get:
bash: phpize: command not found

And ./configure isn't a file listed.

Any suggestions?

Installation problem, unrecognized option --enable-i2c-php

Thanks for your great Library!

Unfortunately I run into some trouble while trying to install the library,

when I enter the command "./configure --enable-i2c-php" a long list of checks and stuff appears but it also writes

configure: WARNING: unrecognized options: --enable-i2c-php

What causes this problem, what could I do?

Using PHP 7.1 and Raspbian 10 (also tried with PHP7.3)

Edit: it works on PHP 7.3 even with that warning
