Minimal GDB in buildroot

Summary

Create gdb-minimal package (without XML support, Python support, Syntax Highlight and such) and switch to it in buildroot.

Owner

Current status

  • Targeted release: Fedora 31
  • Last updated: 2019-04-26
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Create subpackage in gdb source package called gdb-minimal that will contain 2 files:

  • /usr/libexec/gdb-minimal — GDB executable built without optional unneeded features
  • /usr/bin/gdb-add-index — Executable script shared with gdb-headless package (modified to fallback to gdb-minimal if exists)

debuginfo code in RPM needs just gdb-add-index and that one doesn't need any syntax highlight or python plugins to work.

As of Apr 26, following packages would disappear from buildroot: 

boost-regex-1.69.0-6.fc30.x86_64
ctags-5.8-25.fc30.x86_64
gdbm-libs-1:1.18-4.fc30.x86_64
libbabeltrace-1.5.6-2.fc30.x86_64
libicu-63.1-2.fc30.x86_64
libipt-2.0-2.fc30.x86_64
python-pip-wheel-19.0.3-1.fc31.noarch
python-setuptools-wheel-40.8.0-1.fc30.noarch
python3-3.7.3-2.fc31.x86_64
python3-libs-3.7.3-2.fc31.x86_64
python3-pip-19.0.3-1.fc31.noarch
python3-setuptools-40.8.0-1.fc30.noarch
source-highlight-3.1.8-24.fc31.x86_64
sqlite-libs-3.27.2-3.fc31.x86_64

Benefit to Fedora

  • RPM download size for buildroot preparation will go down from 101M to 85M
  • installed buildroot size will go down from 439M to 350M
