I downloaded Spring4D "sglienke-spring4d-ca8037a2fdec.zip" from this link https://bitbucket.org/sglienke/spring4d/downloads/.
And I downloaded DSharp "sglienke-dsharp-2eae62962442.zip" from this link https://bitbucket.org/sglienke/dsharp/downloads/
I tried to build DSharp using Tokyo 10.2.3, and having the following errors - seems DSharp is not compatible with the latest Spring4D commit?

Don't use develop branch of Spring4D if you need compatibility with DSharp but the latest released version.
Currently compatible are Spring4D 1.2.1 and the DSharp spring-1.2.1 branch.
