Are you compiling the module with the same version?

[rjelierse]

Yes, I have compiled HHVM from source, then tried to compile this module using the HHVM tools I'd just compiled.

[d3berger]

I have the same error. Even why I tried this extension-example from hhvm: https://github.com/hhvm/extension-example/issues/7

I was told to try this in #hhvm irc channel

[12:50] denis_: you need to enable the zend compat layer [12:51] ini style: hhvm.eval.enable_zend_compat = true [12:51] hdf: [12:51] Eval { [12:51] EnableZendCompat = true [12:51] } [12:51] or -vEval.EnableZendCompat=true

But it did not help
