Great, thanks Pearu the instructions are a great start, I'll put up a gist, and maybe you or
Wes could take a look when you get a chance?

Thanks again.

Hi Andy,

`make format` is just a convenience step when making development changes to the arrow C++
files that fixes any source formatting issues that I might have introduced when modifying
the source files. You don't have to run it.

I cannot explain why `make format` is failing for you without seeing the failure messages.

Note that the instructions were created just for myself, I just thought that these might be
useful for answering your questions.

Best regards,

I just tried building py-arrow with cuda, using the cheat-sheet that you sent,  Thanks very
much, all modules seem to be building, but I think there is a step that is missing,  I had
a question that I was hoping you could answer; After setting up the environment, configuring
and building, there is a comment in the `make format` line:

make format # after changing cpp/ files

could you explain what this means ( "After changing cpp/ files") I seem to be failing here.

I can post a gist as wes mentioned if need be, but I believe that it has something to  do
with this comment.

Thanks very much, again for the instructions.

Here's mine cheat-sheet for building pyarrow with CUDA support (using conda dependencies):

On Wed, Feb 13, 2019 at 12:11 AM Andrew Palumbo <<>>
I've been trying to build py-arrow with CUDA support, unsuccessfully for some time.
I've tried the directions here:

with -DARROW_CUDA=ON in thr cmake build, with no luck.  I'm running Python3.6 on linux.

I've gone through the cpp dir and the python dir and configured cmake with ccmake; No luck.
 I have built py-arrow several times without CUDA support, but am very interested in the numba

Is there anything Obvious that I am missing?
