NOTICE

NOTE: This project only built a new version emacs-nox package for CentOS 7 x86_64 server.

emacs GUI version disabled a lot of features for removing no need dependencies and saving rpmbuild time :

%configure --without-cairo --without-sound --without-selinux \
  --without-jpeg --without-tiff --without-gif --without-png --without-rsvg \
  --without-imagemagick --without-xft --without-libotf --without-m17n-flt \
  --without-xaw3d --without-toolkit-scroll-bars --without-gpm --without-dbus \
  --without-gconf --without-gsettings

and removed some no need files in emacs-common package :

# slim 'emacs-common' rpm packge
echo "__CLEAN:"
rm -frv %{buildroot}%{_datadir}/emacs/%{version}/etc/{refcards,images,tutorials} \
        %{buildroot}%{_datadir}/emacs/%{version}/etc/[ACEFGHJLNMOPRTW]* \
        %{buildroot}%{_datadir}/emacs/%{version}/etc/D[EI]* \
        %{buildroot}%{_datadir}/emacs/%{version}/etc/{*.ps,*.txt,*gz}

rm -fv  %{buildroot}%{_datadir}/emacs/%{version}/lisp/leim/quail/[!P]* \
        %{buildroot}%{_datadir}/emacs/%{version}/lisp/leim/quail/*b5* \
        %{buildroot}%{_datadir}/emacs/%{version}/lisp/leim/quail/Pu* \
        %{buildroot}%{_datadir}/emacs/%{version}/lisp/leim/ja-dic/* \
        %{buildroot}%{_datadir}/emacs/%{version}/lisp/play/*

find %{buildroot}%{_datadir}/emacs/%{version}/lisp/language/ -type f -not -regex '.*/\(eng\|chin\).*' -delete
find %{buildroot} -name "*.pdf" -delete

You can download the src.rpm and edit the SPEC file to rebuild emacs rpm for your own need.

src.rpm

create src.rpm file on CentOS 8:

# yum install -y rpm-build rpmdevtools
