PHP 8.4.5 error output

/usr/lib64/php8/extensions/opcache.so doesn't appear to be a valid Zend extension

All the other PHP modules load fine.
The ldd command shows this for opcache.so...

        linux-vdso.so.1 (0x00007fff0a3f1000)
        librt.so.1 => /lib64/librt.so.1 (0x00007f91752f6000)

        /lib64/ld-linux-x86-64.so.2 (0x00007f917567b000)

it appears to be a valid so file, but PHP refuses to load it for some reason it is not disclosing....

This seems to be where the error is being generated, I still don't know why...

        if (!extension_version_info || !new_extension) {
                fprintf(stderr, "%s doesn't appear to be a valid Zend extension\
n", path);

How did you build PHP (you can get the ./configure invocation from phpinfo())? What's the output of nm /usr/lib64/php8/extensions/opcache.so | grep -E "(zend_extension_entry|extension_version_info)"?

[abcbarryn]

The command:
nm /usr/lib64/php8/extensions/opcache.so | grep -E "(zend_extension_entry|extension_version_info)"
outputs nothing. It looks like somehow the symbols are getting discarded. Here is the configure info.

It's interesting that opcache is the only module with this issue.

[iluuu1994]

Are you sure you're actually rebuilding opcache? You're passing --disable-all, but not passing --enable-opcache.

[abcbarryn]

Well, opcache.so is being created... So...
