thanks. seemed to go ok. on initial launch, b4a prompted for license. it wasn't where i thought i had put it, and even my notes to myself were wrong (there was a license change on version 6, i think, last year. i didn't update my notes.)
also, when i first started using b4a some years ago, i misread what to do with the additional libraries i downloaded: in my haste i would simply drag each new .jar and .xml into the main anywhere software libraries folder. that error quickly became clear when installing b4a on a different computer; i had to find all the additional libraries one by one and set up a nice, new "extra libraries" folder for them on the new device.
"cc -L -I ...", sad how quickly habits from a former life are forgotten.
