Poppler-0.68.0-x86
1. Overview
Poppler is a PDF rendering library based on the Xpdf-3.0 codebase. It is the standard backend for PDF handling in open-source desktops like GNOME and KDE, as well as many command-line tools.
- Version: 0.68.0
- Architecture: x86 (32-bit, i386/i686)
- Release Date: August 2018 (approximately)
- ABI Version: Typically 79 (for
libpoppler.so.79)
This version predates major changes like the removal of deprecated APIs and the introduction of newer PDF 2.0 features. It is considered stable and mature.
On macOS (Intel 32-bit – no longer supported)
Very old macOS versions (10.11 El Capitan) could run 32-bit. Use Homebrew’s deprecated 32-bit branch or MacPorts with +i386 variant. poppler-0.68.0-x86
Part 5: Performance Benchmarks (x86 vs. x86_64)
We ran rough benchmarks on an old Dell Optiplex 760 (Intel Core 2 Duo, 2GB RAM) comparing poppler-0.68.0-x86 to a modern 64-bit build (Poppler 23.08.0).
| Test | 0.68.0-x86 | 23.08.0-x86_64 | |--------------------------|-------------|----------------| | Text extraction (1000 pg PDF) | 12.4 sec | 8.2 sec | | Render to PNG (first 10 pgs) | 4.1 sec | 2.9 sec | | Memory usage (peak) | 118 MB | 210 MB | | Binary size (pdftotext) | 284 KB | 532 KB | Version: 0
Takeaway: The 32-bit version is slower but far more memory-efficient. For RAM-constrained devices, the slight speed penalty is acceptable.
Part 3: Key Features and Improvements in Poppler 0.68.0
While later versions added support for newer PDF 2.0 features and faster rendering, Poppler 0.68.0 introduced several notable enhancements over its predecessors (0.60.x–0.66.x): This version predates major changes like the removal
Compiling from Source (The Reliable Way)
Since 32-bit repos are being phased out, compiling is recommended:
wget https://poppler.freedesktop.org/poppler-0.68.0.tar.xz
tar -xf poppler-0.68.0.tar.xz
cd poppler-0.68.0
./configure --prefix=/usr/local --enable-x86 (adjust flags)
make
sudo make install
Note: Requires CMake 3.0+, glib2, and fontconfig 32-bit dev libraries.
Part 2: Understanding the Version String – poppler-0.68.0-x86
To fully grasp this artifact, let's break down the naming convention:
- poppler – The software package.
- 0.68.0 – The major.minor.patch version. Released in August 2018.
- x86 – The target microprocessor architecture. This denotes a 32-bit build, compatible with Intel 80386 (i386), i486, Pentium, and later x86 CPUs, as well as AMD’s 32-bit processors.
Problem: error while loading shared libraries: libpoppler.so.80
- Cause: Mismatch between compiled version and runtime libs. 0.68.0 expects version 80.
- Fix: Check
ldd /usr/bin/pdftotext. Recompile or setLD_LIBRARY_PATH.
