4 years ago Hi! Thanks for reporting this.
I was not able to reproduce it using platformio or arduino IDE, and some boards MKRZERO and Feather among others.
This parameter should alway be accepted const as panels are never changed by the menu system however the parameter is defined on the library to be const on AVR's and non const on other platforms (as flash), should not be this way, however before changing it I would like first to reproduce it.
To quick solve your problem you should have a constMEM panel panels[] MEMMODE = ... above that line, please remove the constMem from that, does it solve?
if you can share more details, ie: what IDE are you using or any other pertinent info I will appreciate.
It seems that sketch and library are being build with different defines, are you defining any of USE_PGM, MENU_USERAM, MEMMODE, USING_PGM, USING_RAM in your sketch?

Hi, Firstly, many thanks for your great work developing and maintaining this useful library. I used this library in a project to control a device by sending command using LoRa. The first prototype used Feather 32u4 and worked fine, now I designed a pcb and instead Mega32u4 I have used a SAMD21G18 to increase the memory available for the application. When I compiled the application using Feather M0 board I got this warning during compilation
I tried again using Feather 32u4 and it compile fine. I also tried to compile your example SSD1306Ascii-Button_Navigation, in which I based my application, with Feather M0 and MKRZERO boards and I got the same warning, this is the full output when compiling:
Button_Navigation:152:`` error: invalid conversion from 'const Menu::panel' to 'Menu::panel' [-fpermissive] panelsList pList(panels, nodes, 1); //a list of panels and nodes In file included from D:\GPS_Logger_new\Arduino\libraries\ArduinoMenu_library\src/menuIo.h:178:0, from D:\GPS_Logger_new\Arduino\libraries\ArduinoMenu_library\src/menuDefs.h:62, from D:\GPS_Logger_new\Arduino\libraries\ArduinoMenu_library\src/menu.h:15, from D:\GPS_Logger_new\Arduino\libraries\ArduinoMenu_library\examples\SSD1306Ascii\Button_Navigation\Button_Navigation.ino:25: D:\GPS_Logger_new\Arduino\libraries\ArduinoMenu_library\src/nav.h:22:16: note: initializing argument 1 of 'Menu::panelsList::panelsList(Menu::panel*, Menu::navNode*, Menu::idx_t)' inline panelsList(constMEM panel p[],navNode nodes[],idx_t sz):panels(p),nodes(nodes),sz(sz) { exit status 1 invalid conversion from 'const Menu::panel' to 'Menu::panel' [-fpermissive]
Any help to fix this error will be very welcome. Thanks in advance!
