Premesso il casino che ho combinato in https://forums.gentoo.org/viewtopic-t-422313.html e premesso che comunque devo ricompilare tutto quanto e premesso che sono un folle amante del rischio, ho avuto la bella pensata di emergere GCC 4.0 e usarlo system-wide. Mi dicono che si possa fare, c'è gente che l'ha fatto con soddisfazione.

Ora io mi chiedo: è sufficiente emergerlo e cambiare il profilo con gcc-config?

Oddio, non saprei, però ad esempio potresti chiederlo a flameeyes, lui attualmente ha tutto il sistem compilato con il gcc 4.x

Ciauz :D

Se non erro nel forum ci sono dei lunghi post che riguardano questo argomento, magari puoi cominciare da li e preparati ad avere problemi! :D

Eh, ma non ho trovato mica questi lunghi post...

Comunque cominciamo subito coi problemi:
Code:
/bin/sh: line 1: 31787 Segmentation fault      LD_LIBRARY_PATH=/var/tmp/portage/python-2.4.2/work/Python-2.4.2: CC='i686-pc-linux-gnu-gcc -pthread' LDSHARED='i686-pc-linux-gnu-gcc -pthread -shared' OPT='-DNDEBUG -O3 -pipe -march=athlon-xp -fomit-frame-pointer' ./python -E ./setup.py build
make: *** [sharedmods] Error 139

/bin/sh: line 1:  8419 Segmentation fault      LD_LIBRARY_PATH=/var/tmp/portage/python-2.4.2/work/Python-2.4.2: CC='i686-pc-linux-gnu-gcc -pthread' LDSHARED='i686-pc-linux-gnu-gcc -pthread -shared' OPT='-DNDEBUG -O3 -pipe -march=athlon-xp -fomit-frame-pointer' ./python -E ./setup.py build
make: *** [sharedmods] Error 139


I due errori, relativi a due successive compilazioni dello stesso pacchetto, sembrano identici (a occhio quel che cambia e' il pid del progesso seggato, no?) e si verificano con GCC 4.0.2. Vi risultano? Non riesco a trovare niente di simile in giro a bugzilla o_O.

Poi c'è anche questo che riguarda il 4.1
