here's a good one. C++ program compiles just fine using the ewl_c++ library, as long as the 'int' option for printf and scanf are selected. If I select 'int_FP' then I get the errors:

mingw32-make: *** [ioti-k20.elf] Error 1
I have the 'enable automatic library configurations' checked.
It looks like it's missing some include files along the chain or a library...
Any solutions?
Hi Jenny,
I guess you don't have Erich Steyger's 'mcuoneclipse' PE library installed. Anyhow it's not important, you can just delete any of the PE components that aren't working, they aren't used for this test anyhow.
Thanks,
Marc
