C++ bug? ewl_c++ with int_FP printf/scanf options

[bowerymarc]

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?

[ZhangJennie]

can you please send us the demo code that can showcase the problem?

[bowerymarc]

Hi Jennie, sorry for the delay.  Finally stripped the app code and made a test app showing the problem.  Still occurs with CW5.  Attached.

If you change the properties/settings/library options to int for printf and scanf, it compiles, change to int_FP and you get errors.

Thanks,

Marc

[ZhangJennie]

just open your project with CW10.5.

it appears some compoents ( DSC_LED ) in your project doesn't support  with CW for kinetis.

see attached. can you please check the same

[bowerymarc]

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
