Do you include the unit UIBDATASET in the uses clause?
yes
Do you actually use something from the unit ?
yes, a dropped component from uib component palette, nothing else

if not, try to do so.
It looks like the compiler decided that the UIBDATASET unit uses
threadvars, and includes them in the global list of threadvars, but
then sees that you
don't actually use the unit, so does not include the unit in the link
script.
sounds reasonnable
I have restarted a new project doing this:
1. create a new application
drop a close button and add into the event onclick: Close; Compile & run ok
2. add uiblaz package to project
compile & run: OK 8-)
3. drop TUibDatabse, TUibTransaction, TUibQuery
compile & run: OK
4. implement whatever the test program needs (query execute for read and update data including firebird arrays for which I changed the unit uiblib) compile & run: OK
So far so good.
5. add the unit uibdataset to the interfacse uses clause and guess what: Hint: Start of reading config file

In project options, generate debug data is checked, debugger is set to automatic
heaptrc is NOT checked,
valgrind output is NOT checked
changing to dwarf debugger does not change anything
