This article is a bit old and the content may be outdated, so please refer to it with caution and remember to check the latest official materials (such as documentation, etc.)

It's known to all that compiling is hard. Just record it.

Disclaimer: There may be many errors and unneccesary parts in this post. But the command works, at least on my machine.

Background #

Somewhat old system. No sudo. Want awesome Vim8 +Python3.8

Quick Answer # 

LDFLAGS=-rdynamic ./configure \
    --with-features=huge \
    --enable-fail-if-missing \
    --enable-largefile \
    --enable-multibyte \
    --enable-python3interp \
    --with-python3-command=python3.8 \
    --with-python3-config-dir=$HOME/.pyenv/versions/3.8.5/lib/python3.8/config-3.8-x86_64-linux-gnu \
    --prefix=$HOME

make
make install
bash

Break Down #

Clean before try again #

It is not a good news that the second run is very fast.

make clean distclean
bash

Options v.s. Env vars #

Both are important. For example, do not pass vi_cv_path_python as an option, although it's in lower case 😄

User install # 

--prefix=$HOME
bash

What is python3-config-dir #

A directory containing config.c

-rdynamic?

It just solves undefined symbol: PyTuple_Type: https://github.com/vim/vim/issues/5509#issuecomment-650468467

Also, just go dynamic (with +python3/dyn) is fine:

./configure \
    --enable-python3interp=dynamic \
    --with-python3-command=python3.8 \
    --with-python3-config-dir=$HOME/.pyenv/versions/3.8.5/lib/python3.8/config-3.8-x86_64-linux-gnu \
    --prefix=$HOME
bash

Thank YOU!

You save me. Compiling Vim on RHEL 7 with python support has been killing me for weeks. LDFLAGS=-rdynamic is my saver!

If someone else will be searching for this: --enable-python3interp=dynamic did not work for me but --enable-python3interp works.
