I will be in the office tommorrow again and will try if I also get errors on my MAC with the R10 sdk and the fbx lib linked. I´ll let you know.

Howdy,

OK, it seems I've made some progress.

There seems to be an issue with libiconv library between 64/32 bit. I'm able to compile in R10 but only for intel 32 bit (i386), and only on my 32bit core duo machine running Leopard.
if I open the terminal on that machine and type in:

file /opt/local/lib/libiconv.dylib

... it displays this:

/opt/local/lib/libiconv.dylib: Mach-O dynamically linked shared library i386

On my core 2 quad machine running Snow Leopard, the libiconv library is 64 bit only.
On this machine typing in the above line in the terminal displays this:

/opt/local/lib/libiconv.dylib: Mach-O 64-bit dynamically linked shared library x86_64

When I use that same terminal command with the path to the FBX SDK library file, it displays this:

/Xcode2.5/FBXSDK20102/lib/libfbxsdk_gcc4_ub.a: Mach-O universal binary with 4 architectures   
/Xcode2.5/FBXSDK20102/lib/libfbxsdk_gcc4_ub.a (for architecture ppc) : current ar archive   
/Xcode2.5/FBXSDK20102/lib/libfbxsdk_gcc4_ub.a (for architecture i386) : current ar archive   
/Xcode2.5/FBXSDK20102/lib/libfbxsdk_gcc4_ub.a (for architecture ppc64) : current ar archive   
/Xcode2.5/FBXSDK20102/lib/libfbxsdk_gcc4_ub.a (for architecture x86_64) : current ar archive

So the conclusion may be that the FBX SDK supports all architectures but the libiconv library only supports specific machines.

I'm not sure if there is a universal binary version of libiconv available.

Adios,

FYI I can confirm the issue and have contacted the developers.

I can build plugins linked against the FBX library for Cinema R10 without problems.

With Cinema R11 64bit I got some undefined symbols.

cheers,
Matthias

The readme.txt of the PC version of the FBX SDK explicitly states, that they don't support ppc64. If memory serves me right we once tried to get around those problems (by faking some lib entry points) after discovering, that the SDK contained ppc64 bit code - but finally failed due to a missing method (inside of the FBX SDK).

Howdy,

Thanks Matthias.

Something else I discovered:
When installing the libiconv port using MacPorts, if I add "+universal" to the command like this:

sudo port install libiconv +universal

... then it installs a universal binary version of libiconv

But, on my core 2 quad machine running Snow Leopard, it only installs it for i386 & x86_64.:

/opt/local/lib/libiconv.2.dylib: Mach-O universal binary with 2 architectures   
/opt/local/lib/libiconv.2.dylib (for architecture i386) : Mach-O dynamically linked shared library i386   
/opt/local/lib/libiconv.2.dylib (for architecture x86_64) : Mach-O 64-bit dynamically linked shared library x86_64

... and on my core duo machine running Leopard it only installs it for ppc & i386:

/opt/local/lib/libiconv.2.dylib: Mach-O universal binary with 2 architectures   
/opt/local/lib/libiconv.2.dylib (for architecture ppc7400) : Mach-O dynamically linked shared library ppc   
/opt/local/lib/libiconv.2.dylib (for architecture i386) : Mach-O dynamically linked shared library i386

What I really need is an install for ppc, i386, ppc64 & x86_64, but I haven't found a way to get that yet.

The reason I've installed it from MacPorts (even though the libiconv.2.dylib is in the MacOS sdks) is that to get my plugin to compile in R10 and above, I used the "libiconv.a" static library from the MacPorts installation, since I couldn't figure out the right framework to include or build setting in the project to get it to compile without the link errors.

Adios,

I remember we had a simlar issue with this lib a while ago in a completely unrelated project.

At that time the problem was that the libiconv from /usr/local/lib was used, which only contains just the current architecture. There was another one in a different folder which contained all architectures. I'm just traing to find the exact information on this, but maybe this hint could help you already.

Thanks for that bit of info, Wilfried.

Maybe that will be fixed in fbx 2011?

Haven't looked into that version, but I wouldn't be suprised if they finally dropped PPC support completely.

You're probably right.
