llvmlite 0.16.0 crashes when creating target machine (Ubuntu 14.04, Python 3.5.1)

[scizzorz]

I'm unable to execute the following code on CircleCI's test runners with llvmlite 0.16.0.

import llvmlite.binding as llvm

llvm.initialize()
llvm.initialize_native_target()
llvm.initialize_native_asmprinter()

target = llvm.Target.from_default_triple()
target_machine = target.create_target_machine()
# crashes here and never prints
print('done')

I installed llvm-3.9 like this:

sudo echo "deb http://apt.llvm.org/trusty/ llvm-toolchain-trusty-3.9 main" >> /etc/apt/sources.list
sudo echo "deb-src http://apt.llvm.org/trusty/ llvm-toolchain-trusty-3.9 main" >> /etc/apt/sources.list
wget -O - http://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install llvm-3.9 clang-3.9
sudo rm /usr/bin/llvm-config
sudo ln -s /usr/bin/llvm-config-3.9 /usr/bin/llvm-config

can you check the output of llvm-config --version --prefix --components --targets-built --host-target?

Check the value of llvm.get_process_triple() and llvm.get_default_triple(). If they are too different, you may need to do llvm.Target.from_triple(llvm.get_process_triple()) and/or llvm.initialize_all_targets()

[scizzorz]

llvm.get_process_triple() and llvm.get_default_triple() are both 'x86_x64-unknown-linux-gnu', so I don't think that's the problem.

[scizzorz]

Everything still works correctly with llvmlite 0.15 and LLVM 3.8.

[sklam]

Is this happening only on CircleCI test env? Were you able to replicate this on other setup?

And, just to be sure, what is which llvm-config just before you build llvmlite

[scizzorz]

I tried it on an Arch Linux machine where it worked perfectly with 0.16 / 3.9. I haven't been able to try it on a different Ubuntu machine yet - I'll have access to one in a few hours to check it out.

Can you use miniconda to get prebuilt llvmlite? Or, perhaps the wheel package. I am testing a 0.16.0 wheel. See https://github.com/numba/llvmlite/pull/222#issuecomment-279548150

[scizzorz]

It works on a brand new Ubuntu 16.04 installation after installing LLVM-3.9 in the same way as on the CircleCI test runner. I'll poke around with the test runner later and give that wheel / miniconda a shot.

This actually seems to be the same bug as #93, which has been closed for quite some time.
