racine RPM

D'abord nous avons besoin de créer un répertoire de travail pour générer nos RPM.

Ci-dessous nous allons voir l'arborescence exacte de ce répertoire et où le définir.

Définir le répertoire parent dans notre fichier de macros rpm

ludo@idefix:~ % echo "%_topdir /home/ludo/rpm" > ~/.rpmmacros

Créer les différents répertoires nécessaires

ludo@idefix:~ % for dir in rpm rpm/BUILD rpm/SPECS rpm/SRPMS rpm/SOURCES rpm/RPMS rpm/RPMS/i386
for> do
for>  mkdir $dir
for> done
ludo@idefix:~ %

%description
Monitoring and administration tools for DataDirect Networks s2a appliances.
This tools supports:
  - s2a6000
  - s2a3000
  - s2a8500
  - s2a9500
You will find  the main binary named s2a, with  this binary you could
get a remote access on the storage system and make all cli monitoring
and administration tasks from your unix command line.

Makefile.am

régles permettant de construire notre rpm dans mon Makefile.am

# Build source and binary rpms. For rpm-3.0 and above, the ~/.rpmmacros
# must contain the following line:
# %_topdir /home/ludo/rpm
# cd /home/ludo/rpm ; mkdir -p SOURCES BUILD RPMS/i386 SPECS SRPMS

rpm:
    $(MAKE) distdir ; \
    mv $(PACKAGE)-$(VERSION) $(PACKAGE)-0.0.1 ; \
    tar cvzf $(PACKAGE)-0.0.1.tar.gz $(PACKAGE)-0.0.1 ; \
    $(RM) -rf $(PACKAGE)-0.0.1 ; \
    RPM_TOPDIR=`rpm --showrc | perl -n -e 'print if(s/.*_topdir\s+(.*)/$$1/)'` ; \
    cp $(srcdir)/packages/rpm/s2a.spec $$RPM_TOPDIR/SPECS ; \
    cp $(PACKAGE)-0.0.1.tar.gz $$RPM_TOPDIR/SOURCES/ ; \
    rpmbuild -ba --clean --rmsource $$RPM_TOPDIR/SPECS/$(PACKAGE).spec ; \
    mv $$RPM_TOPDIR/RPMS/i386/$(PACKAGE)-*.rpm packages/rpm ; \
    mv $$RPM_TOPDIR/SRPMS/$(PACKAGE)-*.src.rpm packages/rpm

finalement la commande à lancer pour générer le rpm

Erreurs

check-files

Vérifies si les fichiers indiqués dans le fichier spec correspondent bien à ceux réellement créés.

Checking for unpackaged file(s): /usr/lib/rpm/check-files /var/tmp/s2a-buildroot
error: Installed (but unpackaged) file(s) found:
   /usr/bin/s2a

if you have some files you don't want in the BuildRoot add in your spec file at the files section the define below:

Si cette erreur est normale, ajouter la définition ci-dessous

%files
%defattr(-,root,root)
%define _unpackaged_files_terminate_build 0

Dans tous les cas, ne pas oublier de nettoyer son buildroot dans le fichier spec:

%install
rm -rf $RPM_BUILD_ROOT
