Unrecognized data type 'sometype' errors

[cglzaguilar]

Problem:

At some random time, on some CI, either Travis or AppVeyor. Most of the tests will start failing and the following error will appear:

LOG: '(Line 1 Error "Unrecognized data type 'sometype'.")'

See this log for a detailed example:
https://travis-ci.org/siddhukrs/VireoSDK/builds/366252739?utm_source=github_status&utm_medium=notification

See attachment at the end, to look at a partial log that shows the error.

The issue is that your Vireo module is being loaded before the required type has been defined. The order in which modules are loaded is not defined since they are based on static constructors.

The workaround: Add a dependency to the required Vireo module. By using a DEFINE_VIREO_REQUIRE macro in your module definition, for example:

DEFINE_VIREO_BEGIN(HttpClient)
DEFINE_VIREO_REQUIRE(Synchronization)

This issue is open so we can figure out a better way to manage module loading. The idea behind modules in Vireo is that they are easy to swap out and there is not a strict dependency on them.
