Issues after installation and tests looking good

[ma-wagner]

Hi,
i have install this extension on a Raspberry Pi and the "make test" looking good.

Is there an issue with this line?

Warning: PHP Startup: Unable to load dynamic library 'spi.so' (tried: /home/pi/ext-spi/modules/spi.so (/home/pi/ext-spi/modules/spi.so: undefined symbol: zend_class_unserialize_deny), /home/pi/ext-spi/modules/spi.so.so (/home/pi/ext-spi/modules/spi.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Now i have insert the extension in the php.ini with "extension=/home/pi/ext-spi/modules/spi.so" but the extension isn't loaded. I have look at "php -m".
Is there a sample of code how to use and insert the class into an php-script.

Sorry for that beginner-questions but i'm stucking for days on that point.

result of my "make test":

Build complete.
Don't forget to run 'make test'.

Hi @ma-wagner ! What PHP version are you using? Nevermind, just saw it from your test output.

I'll reproduce it here and get back to you ASAP!

Thanks for your help.

[flavioheleno]

I got to reproduce it and found out that you are probably facing the same issue as myself, RPi OS is installing both PHP 8.0 and 8.1, side by side.

-rwxr-xr-x 1 root root 4.9K Jan 29 04:39 /usr/bin/phpize8.0

The build was executed by PHP 8.0:

The test is being executed by PHP 8.1:

Let me figure out how to fix this :)

[flavioheleno]

Ok, so I figured out that I was missing php8.1-dev and thus update-alternatives --query phpize would point to phpize8.0, which would force the build to use php8.0 instead of php8.1.

Can you ensure that you have php8.1-dev and that update-alternatives --query phpize outputs something like this:

Name: phpize
Link: /usr/bin/phpize
Slaves:
 phpize.1.gz /usr/share/man/man1/phpize.1.gz
Status: auto
Best: /usr/bin/phpize8.1
Value: /usr/bin/phpize8.1

Alternative: /usr/bin/phpize8.0
Priority: 80
Slaves:
 phpize.1.gz /usr/share/man/man1/phpize8.0.1.gz

Alternative: /usr/bin/phpize8.1
Priority: 81
Slaves:
 phpize.1.gz /usr/share/man/man1/phpize8.1.1.gz

[ma-wagner]

Hi @flavioheleno,
so, first you are right php8.1-dev was missing. Now my output look exact like yours. But on make test i get the same and the extension still won't load:

Build complete.
Don't forget to run 'make test'.

Hey @ma-wagner , note that you are still building with PHP 8.0.15 and testing with PHP 8.1.2 (look at the first two blocks of your make test output.

It should look like this:

PHP         : /usr/bin/php8.1 
PHP_SAPI    : cli
PHP_VERSION : 8.1.2
ZEND_VERSION: 4.1.2
PHP_OS      : Linux - Linux valhalla 5.10.63-v7l+ #1488 SMP Thu Nov 18 16:15:28 GMT 2021 armv7l

More .INIs  : 

Note both PHP_VERSION pointing to 8.1.2.

Send the output of the commands below so I can take a look:
update-alternatives --query phpize
update-alternatives --query php-config
update-alternatives --query php

It should output something like this:

pi@valhalla:~/ext-spi $ update-alternatives --query phpize

Note that Best and Value for each query point to the 8.1 versions.

Why there is still 8.0 on work?

Thanks

[flavioheleno]

Did you rebuild?

Run:

make clean
phpize
./configure
make
make test

[ma-wagner]

Did you rebuild?

Oh no. This was my fault. So the test runs without errors. Sorry for that. Now is it necessary to manually insert the extension to the php.ini? Right? I insert it and php -m says that phpspi is loaded. Thats great. Do you have an php-script to test that everything is fine and how i can send some test-data.

Thank you very much for your help and sorry for my beginner-errors.

best regards

[flavioheleno]

You can connect MOSI to MISO using a jumper wire and run this test: https://github.com/embedded-php/ext-spi/blob/main/tests/transfer.phpt
