Build fails on linux-32

[gsakkis]

I got the following error when trying to build on a linux-32 host:

/tmp/TileDB/external/src/blosc/shuffle.cc:280:4: error: #warning Hardware-acceleration detection not implemented for the target architecture. Only the generic shuffle/unshuffle routines will be available. [-Werror=cpp]
   #warning Hardware-acceleration detection not implemented for the target architecture. Only the generic shuffle/unshuffle routines will be available.

@gsakkis you can disable warnings as error to avoid this as a workaround. Please try adding -DTILEDB_WERROR to your cmake command or --disable-werror if you use the bootstrap script.

We will look at fixing the warning so you will not need to disable the werror for the future.

As a general note, we have not verbosely tested 32bit architectures, please let us know if you run into any further problems.

@Shelnutt2 thanks for the prompt response. I managed to built tiledb and tiledb-py with -DTILEDB_WERROR=ON (had to also pass -DTILEDB_S3=OFF).

Btw I got quite a few more warnings for tiledb-py and many tests fail with tiledb.libtiledb.TileDBError: [TileDB::Buffer] Error: Read failed; Trying to read beyond buffer size.

@gsakkis thanks for reporting this. @joe-maley was able to track down the error and it should be fixed by #1739 . We will include this in the next 2.0.7 release.

Great, thanks a lot!

Try setting these before building:

export CFLAGS="-mfpmath=sse -msse2"
export CXXFLAGS="-mfpmath=sse -msse2"
