Hi, this is my first post so I'm going to introduce myself and my project a little. First its '8HandsCoder' because we'll be 4 behind this nickname as it might make it easier for us. Our project is to create a homebrew of SpiraClock
a new kind of agenda : our development is at the stage at which we have SpiraClock running on the PSP except that, recently, as we tried to add meeting exchange via irda, an error suddently appeared. An error, I don't understand and which I can't find any reason for in the modifications we made.
    PSPiral.o(.bss+0x0) : multiple definition of '__packed__'
    main.o(.bss+0x0) : first defined here
    DisplayManager.o(.bss+0x0) : multiple definition of '__packed__'
    main.o(.bss+0x0) : first defined here
    MainMenu.o(.bss+0x0) : multiple definition of '__packed__'
    main.o(.bss+0x0) : first defined here
    TransferMenu.o(.bss+0x0) : multiple definition of '__packed__'
    main.o(.bss+0x0) : first defined here

Below are the headers of the classes concerned and the makefile.. tell me if you need some more info to solve what is for me a total mystery. ;)

After a long search it seems to be that this kind of problem usually occurs :
-with DevCpp and that an update solves the problem
-with badly built libraries
so, I kinda concluded that there's a conflict between __packed__ defined in both SDL_gfx and pspsircs libraries... but I couldn't find any solution to that.
If anyone as another lead to give me on diagnosticing the problem or finding a solution to it I would be very grateful.
