Hi João
The wheel installation seems to work - "import pyKVFinder" and "help(pyKVFinder)" both give sensible replies at the python3 prompt.
Many thanks for this!
from pykvfinder.
I think I've found the answer to this - pip install for this package seems to only work with OSX 10.14+ - getting lots of errors with "pip install -vv pyKVFinder" that have lines like these -
Skipping link: none of the wheel's tags (cp37-cp37m-macosx_10_14_x86_64) are compatible (run pi
Skipping link: none of the wheel's tags (cp310-cp310-macosx_10_15_x86_64) are compatible (run p
but lines like these indicate that if I had a Linux dating back 8 years or more pip install might work
Skipping link: none of the wheel's tags (cp39-cp39-manylinux2014_x86_64, cp39-cp39-manylinux_2_
so I guess I'll have to try to build it locally.

Hi @hrp1000,
Thank you for reporting your issue.
There is no pyKVFinder distribution compatible with your OS (macOS High Sierra - 10.13) in PYPI. The oldest OS supported is macOS Catalina (10.15). I will carefully consider including macOS High Sierra in pyKVFinder deployment.
For now, please install the developmental version by building it locally.
To do this:
- Clone this repository
git clone https://github.com/LBC-LNBio/pyKVFinder
- Build pyKVFinder locally
pip install -e pyKVFinder/
Hope it helps you!
If you have more questions, feel free to ask me.

Thanks for the rapid repsonse.
Unfortunately, building pyKVFinder locally barfs -
running build_ext
building '_pyKVFinder' extension

removing the "-fopenmp" from compiler =flags gives other warnings and error.
I'm unfamiliar with swig - how do I change the default compiler from clang to gcc?
My clang looks like -
[MacPro:~/pykvfinder/pyKVFinder] harry% clang --version
Apple LLVM version 10.0.0 (clang-1000.11.45.5)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Hi again @hrp1000,
Compiling pyKVFinder uses gcc as the C compiler.
You must change the default compiler from clang to gcc, as you said above.
However, I managed to create a wheel for macOS High Sierra (10.13).
Wheel installation
I am sharing pyKVFinder wheels for different python versions here: wheels.zip
To install using the wheels, follow these steps:
- Unzip the wheels.zip.
unzip wheels.zip
- Install the pyKVFinder wheel using pip.
Based on you first comment, you are using python 3.9, so you should run:
pip3 install pyKVFinder-0.4.5-cp39-cp39-macosx_10_13_x86_64.whl
Please let me know if the wheel installation worked.
Build from source
On the other hand, if you still want to build pyKVFinder from source.
First, you need to install:
To install the available default version of GCC on your Homebrew
package manager, type:
brew install gcc
Note: check the GCC version, using brew info gcc
, to make sure you
have installed a version later than 10. Also, Homebrew installation
will not override Clang LLVM compiler link.
If the default version GCC is not later than 10, you can install it directly by typing:
# GCC version 10
$ brew install gcc@10
Then, to set GCC as the default C compiler to build pyKVFinder from source, you would type:
- Create a symbolic link to your custom GCC
$ sudo ln -s $(brew --prefix)/bin/gcc-X /usr/local/bin/gcc
Note: X is the version of GCC you have installed.
If you have more questions, feel free to ask me.

Thanks for reporting this issue, @hrp1000.
If you have any questions, you can open a new issue or reopen this one.

Following up on this issue, pyKVFinder builds in PYPI are now compatible with older versions of macOS.
