And make sure your application and the library are either both 32-bit or both 64-bit.
Ah-Haaa! Bingo, thanks, now it compiles and runs the BassTest from the Delphi BASS .zip.
I missed seeing the "x64" folder in the Linux BASS .zip, just assumed it would run with that unpacked .zip as it was. I never thought the default unpacking would be for x86, seems a little weird, maybe a cruel joke by un4seen?
All good so far, the test complies but will not play a .wav yet. I will dig into it and see what I can do,
Thanks again.
