Please see the setup instructions of the SQL library: www.basic4ppc.com/Downloads.html
I followed the instructions partially again as I have the same problem. I don't have b4ppc installed on my ppc.
I have the following files from SQL1.2.zip in a directory stored on my sd-card:
sqlsample.exe (compiled dev version of SQL.sbp)
When I start sqlsample.exe, the device responds with "Error loading program. IOException"
On my PC I had a same sort of error (System.Io.File ....) but solved that one by putting the system.data.sqlite.dll in the directory the compiled exe is stored.
.NET is installed. Other compiled b4ppc program runs without problem (but they are not using one of the above mentioned dll's)
What did I overlooked?
