Cross compile alembic for arm achitecture #325

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello ,

I know that is it not officially supported but we are trying to cross compile 
Alembic 1.5.1 for Android and IOS arm architectures. It seems the only obstacle 
is partially the Ilmbase toFloat and HDF5. I can compile everything without any 
problems but they both run a helper applications on the target architecture 
during building. We need Alembic only as static library and just to read files 
with Ogawa. Is there anyway to set HDF5 to optional while building Alembic also 
we couldn't find any read examples that don't require HDF5 for reading alembic 
files. I have attached a full log with the errors for i386 IphoneSimulator . I 
also attached the compiled static libs for x86_64 OSX 10.9 , armv7 IOS 7.0 , 
armv7s IOS 7.0, i386 iphone simulator IOS 7.0.

I made a test with the Example1_MeshIn() provided in the wiki. For x86_64 OSX 
10.9 I can read a simple abc file. For the Iphone simulator IOS 7.0 I get a few 
linking warnings. And then it crashes.

There isn't a way yet to turn off HDF5 support via the build system.
It shouldn't be too hard to leave off AbcCoreHDF5 from compiling, but 
AbcCoreFactory would need some light modification so it doesn't try to use 
AbcCoreHDF5.

Are all the architectures you are testing on all little-endian?
Ogawa is explicitly little-endian, and support for reading and writing from 
big-endian archictectures have yet to be implemented. (an exception will be 
thrown)

Hello thank you for your reply. I tested only on the IOS 7.0 simulators at the 
moment which are i386 and x86_64. And Ogawa is working fine I can read a simple 
abc file. 
We need only reading with Ogawa. We haven't yet tested on a device and I guess 
arm64 will be the trickiest architecture to pursue. I will test on a arm7 in 
the next few days. Will it be hard to get Ogawa reading from little-endian 
architecture ?

Arm is biendian and usually defaults to little-endian so you should be ok.

I am still waiting for the developer license. But so far everything works good 
on the simulator. I will post my results when I get it.

I can confirm it works on armv7 without a single problem, I have tested and run 
it on Iphone 4. I don't have access to arm64 but I think it should work.
