Incubator-mxnet: Build using android.arm64 android.armv7 dockers fails, while arm64 and arm7 dockers work

[OferRosenberg]

I'm trying to build MxNet using the multiarch dockers.
While the arm64 and armv7 dockers end succesfully, the Android arm64 and Armv7 docker fails due to compilation errors related to shm_open and shm_unlock - see snapshot below

In file included from src/storage/storage.cc:30:
src/storage/./cpu_shared_storage_manager.h:124:13: error: use of undeclared identifier 'shm_open'
fid = shm_open(filename.c_str(), O_EXCL|O_CREAT|O_RDWR, 0666);
^
src/storage/./cpu_shared_storage_manager.h:129:11: error: use of undeclared identifier 'shm_open'
fid = shm_open(filename.c_str(), O_RDWR, 0666);
^
src/storage/./cpu_shared_storage_manager.h:164:14: error: use of undeclared identifier 'shm_unlink'
CHECK_EQ(shm_unlink(filename.c_str()), 0)
^
3 errors generated.
make: * [build/src/storage/storage.o] Error 1

Is there some configuration I need to do in order to make the android dockers to work ?

Thanks,
Ofer.

It's a bug introduce by a recent commit that add cpu_shared_storage_manager
If you go back to this version https://github.com/apache/incubator-mxnet/commit/c8f7dce0eb49ab1a62ddc2c7e37b93e9b92c2ae4 you will be able to compile android version.

Thanks. So right now, building for Android is jammed, either if trying to build the full MxNet or the Amalgamation build... OK. I'll go back to Nov 16 version for now.

The build should be stable now.
