Subject: undefined reference to `memcmp'
From: Fabian Merki (fabian_at_merkisoft.ch)

[i'm not sure if the mail reached you - sorry, if you got it twice!]

hi everyone

first of all i really love the archos recorder and that you already did so lot of work for open source solution!

here my question (my environment: w2k, cygwin):
after i created the makefile (with the configure-tool) and run make i get the following error:

    sh-elf-gcc -Os -nostdlib -o ./archos.elf ./credits.o ./main.o ./main_menu.o ./menu.o ./play.o ./pla
    ylist.o ./showtext.o ./sound_menu.o ./tree.o ./recorder/bmp.o ./recorder/bounce.o ./recorder/boxes.o
     ./recorder/icons.o ./recorder/sokoban.o ./recorder/tetris.o -L. -lrockbox -lgcc -L../firmware -T../
    firmware/app.lds -Wl,-Map,./archos.map
    ../firmware\librockbox.a(id3.o): In function `setid3v2title':
    id3.o(.text+0x2ac): undefined reference to `memcmp'
    id3.o(.text+0x340): undefined reference to `memcmp'
......

where should this memcmp be - in the lib of cygwin there is such a file which contains that function - but i think this should not be taken because of the -nostdlib... right?

i'm a complete beginner in c (well i'm not new to programming (i know java, vb and other languages quite well)).
so please give me a hint - i think it must be very easy for you!

btw: why is there no one who creates a jvm (java virtual maschine) for the recorder? than it would be much easier to create own applications - i believe.

cheers
fabian
