Build Scripts

1. build-docker-image.sh (270 lines)

   • Downloads 47 RPMs from CentOS 3.9 vault
   • Creates minimal rootfs with rpm2cpio
   • Cleans source directories (make distclean, rm *.o .so *.a .libs)
   • Generates build scripts for each library
   • Builds Docker image

2. build-libraries.sh

   • Starts Docker container in background
   • Executes builds inside container
   • Copies compiled libraries to ./output/
   • Automatically cleans up container

3. verify-rpms.sh

   • Validates all 47 RPM package names
   • 100% verified against CentOS vault

Usage

Rebuild Docker Image

./build-docker-image.sh

Build All Libraries

./build-libraries.sh

Verify RPM Package Names

./verify-rpms.sh

Helper Commands

./pfextlib-docker.sh
# Commands: start, stop, shell, build, build-cppunit, build-fftw, build-hdf5,
#           clean, logs, help

Notes

• Install errors: cppunit shows "files are the same" errors during install phase - this is expected because headers exist in source directory. The compiled libraries are successfully created.
• libstdc++.so.6: Not found in CentOS 3.9 packages. GCC 3.2.3 compiled binaries need libstdc++.so.5 which is present.
• 32-bit libraries: All libraries are 32-bit Intel i386 format, suitable for legacy systems.

Timestamps

• Build Date: November 3, 2024
• Build Time: ~3 minutes for all libraries
• Image Size: ~320 MB (minimal CentOS 3.9 + build tools)

Files Created

• build-docker-image.sh - Main Docker image builder
• build-libraries.sh - Library compilation and extraction script
• verify-rpms.sh - RPM verification tool

Success Criteria

✅ All three libraries compile without errors ✅ Shared objects (.so) created successfully ✅ Static libraries (.a) created successfully ✅ Libraries are 32-bit i386 format ✅ Dependencies are satisfied (libstdc++.so.5, libm, libc, libgcc_s) ✅ Headers and binaries extracted ✅ Build process is reproducible
