GFILE_ALLOW_FLOATS and uGFX source file building error

[Dvor_nik]

Hi! I need same help.

When I try to set

#define GFILE_ALLOW_FLOATS                           TRUE

I have a building error:

I try it on widgets demo. Just try to add this options.

What the best way to output float values through LABEL?

Thanks for finding the bug. Code gets changed and we don't always get to test every code option.

I will fix it in the master repository in the morning (too late for me now).

Using sprintg is probably the best way to get a float value into a label. Given that you have found this problem it looks like you were heading that direction anyway.

inmarket Thank you for fast reply! I will wait.

Please, test this option too:

#define GFILE_NEED_STDIO                             TRUE

I got another compile error with it:

Both these compile bugs should now be fixed.

Thank you very much, inmarket! I going to intensively test it now.
