Cannot build on FreeBSD 14 x86_64

[leonardorame]

Hi, trying to test this on LiveBook running on FreeBSD 14 x86_64, but I get this error:

Generated xla app
** (CaseClauseError) no case clause matching: ["x86_64", "unknown", "freebsd14.0"]

Can you help me with this?

We are not considering this system architecture string, I improved it on main. You can workaround the error by setting XLA_TARGET_PLATFORM explicitly. That said, as far as I understand FreeBSD has it's own libc implementation, so we don't have a precompiled binary for that. So to use XLA on that platform you need to build it locally with XLA_BUILD=true (assuming that XLA supports FreeBSD, but since it's UNIX, I should probably be fine).

Hi @jonatanklosko, thanks for your answer. Could you explain what should I set in XLA_TARGET_PLATFORM?.

[leonardorame]

Hi again @jonatanklosko, I've set this env var:

XLA_TARGET_PLATFORM=X86_64-FreeBSD XLA_BUILD=true

Then cloned the repository and mix deps.get, then mix compile, but I got this error:

** (Mix) Could not compile with "gmake" (exit status: 2).
You need to have gcc and make installed. If you are using
Ubuntu or any other Debian-based system, install the packages
"build-essential". Also install "erlang-dev" package if not
included in your Erlang/OTP version. If you're on Fedora, run
"dnf group install 'Development Tools'".

[jonatanklosko]

Do you have gmake installed?

[leonardorame]

Yes I have gmake, make, gcc.

[jonatanklosko]

You can try running with MAKE=make, MAKE=gmake, I'm not sure what else it can be. If neither works, you can try invoking make explicitly like ROOT_DIR="$(pwd)" BUILD_ARCHIVE="$(pwd)/tmp/build/xla_extension.tar.gz" make to see if there are any meaningful errors.

[leonardorame]

Running this on the cloned repo:

ROOT_DIR="$(pwd)" BUILD_ARCHIVE="$(pwd)/tmp/build/xla_extension.tar.gz" make

First asked for bazel program, so pkg install bazel, then tried again.

Then it needed numpy, so I installed py39-pip, then pip-3.9 install numpy, and tried again.

Then it looks like the source needs g++ 14 minimum, now trying to install it.

[jonatanklosko]

That error looks still related to the compiler version. On CI we actually build with gcc 9, so worth trying that.

Hi @jonatanklosko yes, just pasted that here to document my progress on buiding it. Also asked some FreeBSD folks on the #freebsd channel at irc.libera.chat to help with thiis.

Hi @jonatanklosko as you can see here: https://forums.freebsd.org/threads/trying-to-build-a-linux-c-program-on-freebsd-14-with-gcc9.92731/ I'm asking for help in the FreeBSD forums.

One conclusion I came up is that the Bazel is using /usr/bin/clang, do you think it can be the culpit of my problem. Do you know how to change it to, for example, /usr/local/bin/gcc9?.

[leonardorame]

Just figured out the issue was in OpenXLA, now asking there: https://github.com/openxla/xla/issues/10630

[leonardorame]

I think I made it work in a Linux Jail!

Now I need a small example to test.
