Ajuda emerge (falha emerge media-libs/mesa)

to tentando instalar o chromium pelo emerge (versão 26.0.1410.19), mas o pacote media-libs/mesa-9.1 está com problemas:


vinicius@vinicuis ~ $ sudo emerge chromium -vp

up

parece defeito no ebuild do mesa.

Eu tentaria compilar o chromium novo sem deps, direto em pt-br, após usar o mesa normal pre-compilado, do entropy:

# equo up
# equo i mesa
# LINGUAS="pt_BR" emerge -av --nodeps www-client/chromium

ainda acho que precisa, para o chromium, usar a categoria www-client antes, pq acho que tem outras coisas no portage chamadas chromium.





a proposito, no seu outro post, se quiser usar o eix para achar os pacotes que existam em todos os overlays, invés da home-page que citei, faça isto:

# eix update && eix remote-update

aí ele passara a incluir os Overlays, mas vão aparecer muitos mais pacotes.

alḿe disso, vc pode sincronizar o portage e também os Overlays que usa, e o proprio eix, tudo ao mesmo tempo, ao invés de fazer

# emerge --sync
#emerge portage
# eix-update
# layman -S

faça simplesmente:

# eix-sync && emerge portage

vc estava procurando portato, ele não existe mais. Mas o Emerge ainda tem uma GUI que existe, é o pacote chamado porthole.

eu acho que é coisa no meu pc mesmo, pq ja tinha dado um problema parecido qndo fui instalar um outro pct:
(instalação do samsung-unified driver)

os erros não são os mesmos, esses são erros de emake, e no outro pacote não era, era de econf.

sua memoria RAM e quantos processadores tem? saida do comando

$ gcc-config -l




se nada compila, experimente comentar no seu make.conf, a linha de fomit pointer, desativando-a

CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer"

vai ficar:

CFLAGS="-march=native -O2 -pipe
# -fomit-frame-pointer"

seu make.conf parece com o meu. falou que tirou os #s, não deixe as linhas de rsync adicionais descomentadas no GENTOO MIRRORS, só pode usar um rsync ativo por vez.

depois tente compilar uma coisa pequena, como um pacote "mlocate" com estas opções:

# emerge -av --oneshot --newuse mlocate

o mlocate deu certo, após mudar o make.conf

To rodando o emerge gcc, e depois vou tentar instalar o chromium.

qualquer coisa aviso..

ps.: nuhh, mas como demora, kkk. Nem imagino quanto tempo ia demorar uma instalação do gentoo no meu pc.

após colocar esse make.conf:

instalei o mlocate, normal
fiz um sudo emerge -av autoconf automake make gcc gcc-config eix esearch layman mirrorselect gentoolkit eselect etc-proposals tbem sem nenhum erro.

tentei baixar um ebuild, no gpo.zugaina.org, adicionei a linha em make.conf (PORTDIR_OVERLAY="/usr/local/portage") e, em /usr/local/portage, criei app-portage/mesa (copiei o ebuild pra essa pasta),

rodei um emerge app-portage/mesa , mas também deu erro.

ps.: o ebuild que eu baixei foi do mesa-9.1
