"LD rockboxui" makes "bad magic number (not a Mach-O file)"

[totoetlititi]

Hi,

I have lot of problems with compiling Rockbox...
I'm using a mac (Os 10.4.7).
I can cross compile Rockbox for my ipod mini 2g, I have no problem, but when I want compile for UIsimulator, I have :

Code: [Select]

LD rockboxui
/usr/bin/ld:~/rockbox-devel/buil-dir/apps/lang.o bad magic number (not a Mach-O file)
/usr/bin/ld: ~/rockbox-devel/buil-dir/apps/language.o bad magic number (not a Mach-O file)
/usr/bin/ld: archive: ~/rockbox-devel/buil-dir/libbitmapsnative.a has no table of contents, add one with ranlib(1) (can't load from it)
/usr/bin/ld: warning multiple definitions of symbol _memset


Why ?
What does it mean ?
(I'm using powerpc-apple-darwin8-gcc-4.0.1)

Thanks !

It means your ld is very odd, or possibly that you have some sort of mixed build. Have you tried doing a 'make clean' first0

[totoetlititi]

Thanks, that's right. A "make clean" solves this problem.

But now I have this :

Code: [Select]

powerpc-apple-darwin8-gcc-4.0.1: unrecognized option '-shared'
/usr/bin/ld: warning multiple definitions of symbol _memset
~/rockbox-devel/buil-dir/libcodec.a(codeclib.o) definition of _memset in section (__TEXT,__text)
/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/../../../libSystem.dylib(memset.So) definition of _memset

damned...

[Bagder]

I find it odd that others have managed to do this in the past...

Cut out the -shared option from the Makefile (we need to make configure detect darwin and do this automatically) and remove the definition of memset in the codeclib and retry.

There's a patch here. It will allow you to build the ui simulator on a mac.

[totoetlititi]

It's very strange...
I have applied the patch, and all Makefile which use the flag "-shared" is modified by:

Code: [Select]

ifeq ($(UNAME), Darwin)
SHARED_FLAG=-dynamiclib -Wl,-single_module
else
SHARED_FLAG=-shared
endif

and... I have always this error :

Code: [Select]

powerpc-apple-darwin8-gcc-4.0.1: unrecognized option '-shared'
 

The error "multiple definitions of symbol" is for:
_memset
_memcpy
_memmove
_strcmp
_strlen
_memchr
_strcat
_strcpy
_memcmp
in libcodec.a...

I tried to remove all this function in codeclib.c, and now I have :

Code: [Select]

/usr/bin/ld: Undefined symbols:
_main

re-damned...

[totoetlititi]

Ok, I finally find the mistake...
Barry, your patch fails to patching the Hunk#3 of apps/codec/Makefile:

Code: [Select]


patching file apps/codecs/Makefile
Hunk #1 succeeded at 12 with fuzz 1.
Hunk #2 succeeded at 85 (offset 1 line).
Hunk #3 FAILED at 101.

I manually modified the line 101, and it works like a charm !

But perhaps you can add in your patch this patch:

This solves the crashs when exiting uisimulator.

Thanks for all !
