Unable to build owl on ARM v8 architecture

[abhi18av]

Hi OWL Team

I'm trying to setup a scaleway ARM-64 server for OCaml and OWL experimentation and almost everything installs correctly - apart from the eigen folder.

I've installed the dev package in ubuntu-18.04 via the following command

root@cub:~# apt install libeigen3-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libeigen3-dev is already the newest version (3.3.4-4).
0 upgraded, 0 newly installed, 0 to remove and 145 not upgraded.

Here's the build log

Could you please help me figure out what's the problem?

Hi @abhi18av, the eigen library indeed has installation issue on across platforms. Here the error is caused by that SSE instructions are not available on ARM. There is plan to remove the eigen library from dependencies in the future. For now, to install and run Owl on ARM, I would suggest installing Owl from source code. The dockerfile could be of help. I would be glad to help if you have any further problem on installation.

[abhi18av]

Thanks for the update @jzstark 👍

While doing my own troubleshooting I came across a similar issue people face while building tensorflow on R-Pi.

Here's link to that https://gist.github.com/EKami/9869ae6347f68c592c5b5cd181a3b205

You can search for the eigen word and it'll lead you to this bitbucket URL https://bitbucket.org/eigen/eigen/get/5a0156e40feb.tar.gz

I don't exactly know what this means, but I thought it might be informative for people who have the right knowledge :)

[abhi18av]

Following the manual installation instruction leads me to the following status

root@cub:~/projects/code/scratch/owl# jbuilder external-lib-deps --missing @install
Error: The following libraries are missing in the default context:
- eigen
Hint: try: opam install eigen

Am I doing something wrong?

[jzstark]

The manual instruction assumes prerequisites such as BLAS library and Eigen are already properly installed. I would generally follow the steps listed in the Dockerfile : install required libraries and opam packages, then install eigen, and then install Owl -- like Tensorflow, installation on RPi is not quite straightforward sometimes :)

Hi @jzstark , I tried following the instructions in the Dockerfile but at the very end, it's not really able to find the libraries still.

Thanks for the information. That means the eigen is successfully installed, but you might need to copy the generated eigen library to a searchable path. For example, run this command to copy libeigen.a file to /usr/local/lib/, which is normally a searchable path.

@jzstark , I followed through with your suggestions and it seems that the problem is about some symbol LAPACKE_dlagsy and other such symbols from dynamically loaded libraries

I'll paste here what the terminal throws out

This error is caused at linking with OpenBLAS library. I assume the libopenblas-dev liblapacke-dev libraries are both properly installed with apt-get and can be found by the system; and that the eigen library is also installed and can already be used in utop. This should be the one last issue before successful installation of Owl. Later tonight I'll try to find a RPi and reproduce this issue. I'll come back to you tomorrow. Sorry for the inconvenience.

Also, note that installing things in root and using sudo might change the system variables like PATH and LD_LIBRARY_PATH. Besides, sometimes run make cleanall and then make install again might be helpful.

[abhi18av]

I understand @jzstark and I'd also like to thank you for your pro-activeness here :)

I"m trying out the make cleanall approach and hoping for the best🤞

[abhi18av]

As for the other libraries, I've already installed them using the package manager

root@cub:~# apt install libopenblas-dev

libopenblas-dev is already the newest version (0.2.20+ds-4).

For the sake of documentation, I'm reproducing everything I did at this stage.

Warning, the logs are really verbose :)

Here's the gist

[jzstark]

Thanks for the detailed information! It looks like that there is still issue installing eigen. The only possible solution I can now think of is to remove the flto flag when compiling eigen. Please see the updated Dockerfile. Of course, make cleanall before installation should do no harm.

Also, please note that in this Dockerfile, line 58 is specifically for RaspberryPi, so probably you don't need it.

Another possible source of issue is the -llapack flag in configuration. Please see #344 for detail. However, since you install those libraries with apt-get rather than from the OpenBLAS source code, I don't think it's a very likely cause.

Anyway, by following this Dockerfile, I build a ARM docker image, without being able reproduce this issue. So if the aforementioned solution still doesn't work, could you please kindly help to provide some software / hardware platform information so that I can further investigate it. Meanwhile, you can try the ARM docker image on you machine.

[abhi18av]

I followed through with your suggestions and I'm reproducing here the commands I entered and the response I recieved,

Also, I'm using the Scaleway - ARM64-v8 server for trying things out

[mseri]

@abhi18av eigen master branch and the current master branch of owl allow to override all the C and CPP flags by setting the right env variables (refer to owl and eigen's readmes for the names and the default values). Does this solve your issue?

[ryanrhymes]

The issue seems solved to me, closing it now. But feel free to reopen in case the issue is still there.

[abhi18av]

Hello @ryanrhymes and @mseri , I'll give it a go today.

[abhi18av]

Could you tell me which flags to override? I'm a bit lost at the moment, however my ARM server is all set to go.

[mseri]

Manually compile and install openblas if you are using ubuntu, it should go in /opt/OpenBlas by default I think.look where it imstalls the pkgconfig configuration, usually in “prefix/lib/pkgconfig” but you need to double check.

From the beginning of the discussion above i see that one issue was gcc: error: unrecognized command line option ‘-mfpmath=sse’, so I would say look on eigen and owl readmes the default flags and remove that option from them (and incrementally any other failing one).

Then run

opam remove eigen owl-base # add owl if it is also installed
opam update

PKG_CONFIG_PATH=/path/to/nnee/openblas/lib/pkgconfig \
EIGENCPP_OPTFLAGS=“your set of flags” \
EIGEN_FLAGS=“Your set of flags” \
OWL_CFLAGS=“your set of flags” \
opam install eigen owl owl-base

[ryanrhymes]

We probably need to dedicate one chapter in ocaml.xyz online doc to explain and demo the new installation demo process, this page is quite outdated now: http://ocaml.xyz/chapter/install.html

[mseri]

@abhi18av Can you check if what we do in https://github.com/owlbarn/owl/blob/master/docker/Dockerfile.ubuntu.arm is enough for the build to work?

If not we may also need to recompile openblas as done in https://github.com/owlbarn/owl/blob/master/docker/Dockerfile.ubuntu

[abhi18av]

Hi Marcello, please give me time till tomorrow and I shall check. This week turned out to be a busy one due to a family function.

Apologies for the delay.
