We just built a CubeSQL client library for Mac, the cubesql.dylib. You can download it in our download area in Libs folder.
As you may know you can use SQL functions in both MBS Xojo SQL Plugin and MBS FileMaker Plugin to connect to a CubeSQL server and perform queries. Since SQLabs does not yet provide prebuilt libraries for Mac & Linux, we just made one for Mac 32 and 64 bit with OpenSSL embedded.
For Xojo, you can of course use InternalCubeSQLLibraryMBS module which has library embedded for all platforms right into our MBS Xojo SQL Plugin.
For FileMaker, please use library files. For example in your script set the library path as a connection option.
MBS( "SQL.SetConnectionOption"; $Connection; "CUBESQL.LIBS"; "c:\CubeSQL\cubesql.dll" )
MBS( "SQL.SetConnectionOption"; $Connection; "CUBESQL.LIBS"; "/Users/cs/Desktop/cubesql.dylib" )
Of course you need different paths depending on your installation. e.g. you can put the CubeSQL library in the same folder as the plugins.
