I know AMD64 is not officially supported yet, but I'm reporting this crash regardless:

Code:

Repro steps:
- Ubuntu 8.04 AMD64, XBMC branches/linuxport r13213
- Start XBMC and navigate to Music
- Select a directory with MP3 files
- crash

It seems that libid3tag-i486-linux.so is built 32-bit:

Code:

$ objdump -f BUILD/system/libid3tag-i486-linux.so

BUILD/system/libid3tag-i486-linux.so:     file format elf32-i386
architecture: i386, flags 0x00000150:
HAS_SYMS, DYNAMIC, D_PAGED
start address 0x00005970

$ objdump -f /usr/lib/libid3tag.so.0

/usr/lib/libid3tag.so.0:     file format elf64-x86-64
architecture: i386:x86-64, flags 0x00000150:
HAS_SYMS, DYNAMIC, D_PAGED
start address 0x0000000000006c60

Are there instructions anywhere on configuring the build to build 64-bit versions of libraries?

Thanks.

I just checked out branches/linuxport/sources and built libid3tag, then copied the libid3tag.0.3.0.so to XBMC/BUILD/system/libid3tag-x86_64-linux.so, then changed DllLibid3tag.h to load that instead, and that crash is no longer present.

However, when I try to play an MP3, I get a similar crash:

I tried building MADCodec, but it doesn't want to build:

Code:

g++ -o MADCodec/MadMp3Decoder.o -c MADCodec/MadMp3Decoder.cpp -Ilibmad-0.15.1b -D_LINUX
gcc -shared -o MADCodec-i486-linux.so  MADCodec/MadMp3Decoder.o libmad-0.15.1b/.libs/libmad.a `cat ../../../XBMC/xbmc/cores/DllLoader/exports/wrapper.def` ../../../XBMC/xbmc/cores/DllLoader/exports/wrapper.o
/usr/bin/ld: libmad-0.15.1b/.libs/libmad.a(timer.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
libmad-0.15.1b/.libs/libmad.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [MADCodec-i486-linux.so] Error 1

[jlongstreet]

I got MADCodec to build by adding -fPIC to CFLAGS in libmad-0.15's Makefile.

I'd be interested in doing these changes up right and submitting patches if someone could fill me in on the 64-bit status and procedures for building libraries in 64-bit.

Thanks.

I'll look into this.

If you could submit a patch for your fix for libid3tags that would be great. Otherwise I'm going to have to repeat your work.

[jlongstreet]

Here's a patch for both libid3tag and MADCodec, along with the .so's. I tried uploading it to the Sourceforge tracker three times and it kept dropping the connection.

Internet Explorer or Firefox, ...in either care know that SourceForge.net have troubles sometimes and in those cases you just have to wait to try again later.

Ok, I got it to work after a few more tries:

The changes I have to make AACCodec and libfaad under dvdplayer work are a little more complicated, though. I'll try to put together a tarball that extracts into /branches/linuxport/sources for the new files and diffs for the modified source, although with directories being added/removed/renamed the SVN merging might be a little problematic.

[malloc]

Just added to svn in revision 13267. Could you confirm that this is now working?

[malloc]

I'm pretty sure it's not working. Can you give me the exact commands you issued to build libid3tag-x86_64-linux.so?

[malloc]

Okay, working now.
