ugui with arduino/teensy

[epikao]

Hello, I try to implemente ugui with arduino/teensy 3.2, but unfortunately if I implement in the sketch #include "ugui.c" I get follow error:

invalid conversion from 'void*' to 'void ()(UG_COLOR) {aka void ()(long unsigned int)}' [-fpermissive]

?? whats wrong?

Hi,
i have a similar issue when trying to compile for teensy 3.2, i get the following message:

`uGUI_Test: In function 'void loop()':
uGUI_Test:64: warning: ISO C++ forbids converting a string constant to 'char*'
UG_PutString (0,0, "Beginning System Initialization");

                                                   ^

                                                  ^

can you show me your sketch code?

I've moved on to another display which means I don't need the ugui, thank you though!

What you have noticed are actually bugs in uGui. They are known - but the author never merged fixes from other people.

Basically - several functions miss 'const' attributes from their arguments. This causes sever issues for architectures which access 'const' variables ( mostly texts) differently then variables.

what do you think, is it difficult to fix that problem? Or just need to change some variable, functions type??

Because is really only one error:
invalid conversion from 'void*' to 'void ()(UG_COLOR) {aka void ()(long unsigned int)}' [-fpermissive]

it cannot be so complicated to solve that??
