 Posted: Wed Jul 13, 2005 9:19 pm Post subject: [TIP] compilare pacchetti mozilla-* con *FLAGS a piacere |
 |
|
per chi come me ha sempre desiderato compilare firefox con -Os o altre flags più spinte di quelle permesse dall'ebuild, ecco a voi un piccolo tip. (sperando che non sia già stato fatto da altri)
per fare ciò è sufficiente mettere nell'overlay l'eclass mozconfig opportunamente modificata e il tip funzionerà (almeno dovrebbe) con tutti gli ebuild che la utilizzano già presenti nel portage tree, senza che sia necessario fare un'overlay anche di essi. (quindi d'ora in poi tutte le compilazioni di thunderbird, firefox, ecc useranno le {C,CXX}FLAGS del vostro /etc/make.conf)
per annullare l'effetto è necessario eliminare (o rinominare) il file.
copiare il seguente file in ${PORTDIR_OVERLAY}/eclass/mozconfig.eclass

spero sia utile a qualcun altro oltre che a me.
Ciao!
EDIT: era banale ma mi è venuto in mente dopo
per circoscrivere l'effetto di questo tip basta dare un nome all'eclass diverso (es: mozconfig-nofilter.eclass)
e copiare gli ebuild che si vogliono compilare nell'overlay modificando la riga
| Code: | | inherit ... mozconfig ... |
in
| Code: | | inherit ... mozconfig-nofilter ... |
