Gentoo GCC 出问题解决方法
Gentoo GCC 被删除后解决方法
1.在其他机器上 #quickpkg gcc
* Building package for sys-devel/gcc-4.7.3-r1 ...
* Packages now in '/usr/portage/packages':
* sys-devel/gcc-4.7.3-r1: 28.5M
Gentoo sys-devel # pwd
/usr/portage/packages/sys-devel
Gentoo sys-devel # ls
gcc-4.7.3-r1.tbz2
2.scp gcc-4.7.3-r1.tbz2 到缺少GCC
3.把gcc-4.7.3-r1.tbz2 放到sys-devel 目录下
mkdir -p /usr/portage/packages/sys-devel
4.(chroot) Gentoo-20121221 ~/test # emerge -1avqK gcc #本地安装GCC
emerge: there are no ebuilds to satisfy ">=dev-libs/mpfr-2.4.2".
(dependency required by "sys-devel/gcc-4.6.3" [binary])
(dependency required by "gcc" [argument])
5.需要有gcc 放到 sys-devel
/usr/portage/packages/sys-devel
gcc-4.6.3.tbz2
6. 还有 mpfr，mpc-1.0.1放到 dev-libs.quickpkg mpfr 放到哪个目录，就放到哪个目录。
'/usr/portage/packages': dev-libs/mpfr-3.1.1: 491K
(chroot) Gentoo-20121221 /usr/portage/packages/dev-libs # emerge -1avqK gcc
[binary N ] sys-devel/gcc-4.6.3 USE="cxx fortran mudflap (multilib) nls nptl openmp (-altivec) -doc (-fixed-point) -gcj -graphite -gtk (-hardened) (-libssp) -lto -multislot -nopie -nossp -objc -objc++ -objc-gc -regression-test -vanilla"
Would you like to merge these packages? [Yes/No]
7.还有gcc-config 要安装一下
(chroot) Gentoo-20121221 /usr/portage/packages/sys-devel # emerge -1avqK gcc-config
[binary N ] sys-devel/gcc-config-1.7.3
Would you like to merge these packages? [Yes/No]
