Installing pyenv itself is fine.
However, an error occurs when building the Python version.
Problem Description
Using the command:
pyenv install 3.10.15
Shortly after, the system throws a series of error messages:
Downloading Python-3.10.15.tar.xz...
-> https://www.python.org/ftp/python/3.10.15/Python-3.10.15.tar.xz

Huh? Just another day in the life of a developer!
Fixing the Problem
Here are a few potential fixes:
1. Install Dependencies
First, update the system packages:
sudo apt update && sudo apt upgrade -y
Then, make sure the necessary packages are installed:
sudo apt install -y build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev \
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
The system tells us that all the above packages are already up-to-date.
So, it’s not the problem here.
2. Check GCC Version
Update the GCC version:
sudo apt install --reinstall gcc
Then try again, but the same error persists.
Looks like this isn’t the issue either.
3. Check the Log File
From the error messages, find the location of the log file and take a look:
less /tmp/python-build.20241125102533.16978.log
Inside, there’s a ton of information. Let’s go straight to the last section:
gcc -c -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers -Werror=implicit-function-declaration -fvisibility=hidden -I./Include/internal -I. -I./Include -I/home/user/.pyenv/versions/3.10.15/include -I/home/user/.pyenv/versions/3.10.15/include -fPIC -DPy_BUILD_CORE -o Programs/_testembed.o ./Programs/_testembed.c

/tmp/ccTVJtRi.s: Assembler messages:
/tmp/ccTVJtRi.s: Internal error in emit_inc_line_addr at ../../gas/dwarf2dbg.c:1643.
Please report this bug.
make: *** [Makefile:1856: Objects/typeobject.o] Error 1
make: *** Waiting for unfinished jobs....
The error here says:
- "Internal error in emit_inc_line_addr at ../../gas/dwarf2dbg.c"
This points to an issue with the assembler component of binutils, typically indicating a bug or incompatibility in the package.
4. Reinstall Binutils
Great, now we know the problem. Let’s update binutils:
sudo apt update
sudo apt install --reinstall binutils
After updating, try running:
pyenv install 3.10.15
This time, it works, and the problem is resolved.
