Notes conversion paquet DEB en RPM avec Alien - exemple avec jodconverter-java

Portage de jodconverter-2.2.2 de Debian sur RedHat7

Sur Debian 

apt-get download jodconverter libjodconverter-java
fakeroot alien -r *.deb

On envoi les paquets RPM sur la Redhat

Sur RedHat7 

yum --enablerepo=extras install epel-release
yum install rpmbuild
rpmrebuild -e -p jodconverter-2.2.2-9.noarch.rpm

Ici il faut ôter les lignes correspondant à des répertoires 

%dir %attr(0755, root, root) "/"
%dir %attr(0755, root, root) "/usr"
%dir %attr(0755, root, root) "/usr/bin"

ou 

alien -r -g -v plop_all.deb
cd plop
 
sed -i 's#%dir "/"##' *.spec
sed -i 's#%dir "/opt/"##' *.spec
sed -i 's#%dir "/usr/bin/"##' *.spec
 
#rpmbuild --target=noarch --buildroot "$PWD" -bb *.spec
rpmbuild --buildroot "$PWD" -bb *.spec

FIXME plus bas nous ferons un ln -s /usr/share/java/jodconverter-cli-2.2.2.jar /usr/share/java/jodconverter-cli.jar Il doit avoir une manière plus propre de faire cela.

Ici nous effacerons simplement la ligne ci-dessous 

%attr(0777, root, root) "/usr/share/java/jodconverter-cli.jar"

Sinon nous aurions cette erreur 

attention : Explicit %attr() mode not applicaple to symlink: /root/.tmp/rpmrebuild.4635/work/root/usr/share/java/jodconverter-cli.jar

Construisons de nouveau notre RPM 

cd rpmbuild
rpmbuild --target=noarch -bb

Même chose avec l'autre paquet libjodconverter-java-2.2.2-8.noarch.rpm 

rpmrebuild -e -p libjodconverter-java-2.2.2-8.noarch.rpm
cd rpmbuild
rpmbuild --target=noarch -bb

Correction chemin et dépendance : FIXME: Note il aurait été préférable de modifier le script bash /usr/bin/jodconverter que de faire des liens symbolique dans tous les sens 

yum install libreoffice-core libreoffice-ure libreoffice-writer
yum install apache-commons-io slf4j maven xstream
 
ln -s /usr/share/java/jodconverter-2.2.2.jar /usr/share/java/jodconverter.jar
ln -s /usr/share/java/jodconverter-cli-2.2.2.jar /usr/share/java/jodconverter-cli.jar
ln -s /usr/lib64/libreoffice /usr/lib/
ln -s /usr/lib64/libreoffice/ure/share/java/ridl.jar /usr/share/java/
ln -s /usr/share/java/slf4j/slf4j-api.jar /usr/share/java/slf4j-api

En cas de pb 

bash -x $(which jodconverter)

Notes compression

pigz/unpigz remplace gzip

7z 7zip PeaZip

lzop, lz4 pour la rapidité (similaire à gzip)

xz / pxz pour la compression

pbzip2

rsync ⇒ voir gzip --rsyncable

ppack_lz.sh 

#!/bin/sh
