I ran into an issue with PyMC3 where it was expecting a certain symbol that Python wasn't compiled with.
Exception: Compilation failed (return status=1): /usr/bin/ld: /home/rozek/.pyenv/versions/3.8.2/lib/libpython3.8.a(floatobject.o): relocation R_X86_64_PC32 against symbol `PyFloat_Type' can not be used when making a shared object; recompile with -fPIC. /usr/bin/ld: final link failed: bad value. collect2: error: ld returned 1 exit status.
Since I use pyenv for Python version management, it turned out that I only needed to modify the CFLAGS variable to get this working
CFLAGS="-fPIC" pyenv install 3.8.2
Turns out you can configure other flags during Python installation as well such as CPPFLAGS and LDFLAGS.
