installation

Hi,

I'm attempting to install ANN-SoLo in a new conda environment. When I run pip install, I get the following error

Building wheels for collected packages: ann-solo
  Building wheel for ann-solo (setup.py) ... error
  error: subprocess-exited-with-error

Any help appreciated, Colin

Hi Colin, apologies for such a long delay before getting back to you.

Which operating system are you using (I assume Linux from the log, but just to make sure)? What is your gcc version (output of gcc --version)?

Please make sure to follow the installation instructions as detailed in the wiki. We're working on making this a one-step and multi-OS installation procedure, but for now, it still involves a few different steps.

Hi @sarahbeenie - it looks like you're on MacOS. Is that right? If so, you'll need to make sure that the Xcode Command LIne Tools are installed. From your terminal, run:

xcode-select --install

After it installs, try installing ANN-SoLo again in a fresh session. Thanks!

[sarahbeenie]

Hi Will, thanks for your quick response!

Yes, I'm on MacOS. I tried your suggestion but it looks like I already had Xcode Command Line Tools installed. In a fresh session, I got the same error as above.

Any more help would be really appreciated.

Thanks, Sarah

[bittremieux]

IIRC macOS uses Clang instead of GCC as a compiler, right? Can you check which one you have and which version it is?

[sarahbeenie]

Thanks for the help!

I have this one here - Apple clang version 15.0.0 (clang-1500.1.0.2.5)

Hello everyone!

I encountered the same issue and I could only resolve it by installing python 3.7. Python 3.8 and 3.9 was giving me the same error as mentioned byt the OP.

Hope this helps!

Kamil

[bittremieux]

Thanks for the top Kamil. We'll have to do some additional tests on those later Python versions and improve the installation so that it works for all versions and platforms.
