Why is there no compiled pdo_snowflake.so available?

[tvpmb]

The build process isn't simple to understand and lacks some context, why is there no pre-compiled version (like many other PHP extensions)?

[sfc-gh-kwagner]

We know that the build process is a bit complex and we're working to make the build process easier for people to use while also providing prebuilt libraries for Windows, Linux and OS X. Are you having trouble building pdo_snowflake.so?

[tvpmb]

Yeah - its just not clear what I need to do.... I ended up running build_pdo_snowflake.sh, but it failed, wouldn't it be easier to publish a "dist" folder to the repo that contains that file? I could be up and running in 2 minutes if I had that.

Ah I see you're building it on OS X and PHP 5.X (I'm guessing the PHP version based on the PHP API version). Right now it is only available for Linux and only for PHP 7.X. We are working on getting OS X and Windows builds working and then the current plan is to have a dist folder for the repo with prebuilt libraries for each platform/supported PHP version.

We don't have any plans of supporting PHP 5.X since the PDO interface between PHP 5.X and 7.X is quite different.

Ok - I think I realized this as well, trying on an Ubuntu machine now.

[sfc-gh-kwagner]

Let me know how building on Ubuntu works out. I'll keep this ticket open and comment here when OS X support is ready and I have a prebuilt library for you to use.
