I am currently trying to compile the latest stable release of Python (3.7.3 at the time of writing) on a small ARM device (a DNS-323A1 NAS), running Alt-F (a custom linux-based firmware) using GCC 4.3.3. Unfortunately, I've hit a major snag that I just can't seem to get past.

In short, the compilation goes well until the [sharedmods] stage, where it encounters an error related to readline and the module not having been compiled with -fPIC. I've included a truncated log (taken from a second make invocation after the first failed) that displays the issue.

This is the ./configure invocation I've used:
'--prefix=/usr' '--enable-shared' '--with-system-expat' '--with-system-ffi' '--with-ensurepip=yes' '--enable-optimizations' '--enable-ipv6' 'CFLAGS=-fPIC' 'CXXFLAGS=-fPIC'

Any assistance would be much appreciated.

I presume you are trying to compile CPython. Perhaps you might do better with MicroPython, designed for micro devices. Steve, do you know anything about CPython on Arm with linux?

[JarlGullberg]

That's correct, CPython. I'm not sure if MicroPython would fit the bill for
me, since this system is a full-blown Linux system.

After some more testing, I can add that the same issue crops up when attempting to compile Python 2.7.16 as well.

[terryjreedy]

Jarl, I don't know if we support compiling on such devices, even though the OS is linux. I suggest that you ask on python-list, where someone might have the experience to help you.

[vstinner]

Use GCC option -fPIC for shared objects, please

Did you try that? I guess that the configure.ac block about CCSHARED="-fPIC" doesn't handle your operating system.

Try to modify manually Makefile to use "CCSHARED=-fPIC", make clean, and try make again.

I suggest starting without --enable-optimizations until you solve the build errors.

3.7 is no longer maintained. Please create a new issue if you are having this problem with a current version (>= 3.9).
