Archlinux将gcc的评级从5.2降至4.8

Question

我想在目前的ArchLinux上降低gcc的评级。

    Makefile:545: recipe for target 'libstdc++.la' failed
    make[6]: *** [libstdc++.la] Error 139
    make[6]: Leaving directory '/tmp/yaourt-tmp-jester/aur-gcc48/src/gcc-        build/x86_64-unknown-linux-gnu/libstdc++-v3/src'
    Makefile:575: recipe for target 'all-recursive' failed
    make[5]: *** [all-recursive] Error 1
    make[5]: Leaving directory '/tmp/yaourt-tmp-jester/aur-gcc48/src/gcc-        build/x86_64-unknown-linux-gnu/libstdc++-v3/src'
    Makefile:480: recipe for target 'all-recursive' failed
    make[4]: *** [all-recursive] Error 1
    make[4]: Leaving directory '/tmp/yaourt-tmp-jester/aur-gcc48/src/gcc-        build/x86_64-unknown-linux-gnu/libstdc++-v3'
    Makefile:386: recipe for target 'all' failed
    make[3]: *** [all] Error 2
    make[3]: Leaving directory '/tmp/yaourt-tmp-jester/aur-gcc48/src/gcc-        build/x86_64-unknown-linux-gnu/libstdc++-v3'
    Makefile:12181: recipe for target 'all-stage1-target-libstdc++-v3' failed
    make[2]: *** [all-stage1-target-libstdc++-v3] Error 2
    make[2]: Leaving directory '/tmp/yaourt-tmp-jester/aur-gcc48/src/gcc-build'
    Makefile:19114: recipe for target 'stage1-bubble' failed

    make[1]: Leaving directory '/tmp/yaourt-tmp-jester/aur-gcc48/src/gcc-build'
    Makefile:885: recipe for target 'all' failed
    make: *** [all] Error 2
    ==> ERROR: A failure occurred in build().
        Aborting...
    ==> ERROR: Makepkg was unable to build gcc48.
    ==> Restart building gcc48 ? [y/N]
    ==> ------------------------------
    ==> 

当我试图通过yaourt - to确认需要的gcc48安装gcc时

有人知道它为什么不起作用吗。这些错误对我没有任何帮助。

Answer 1

在arch linux上，可以使用shell命令：

gcc降级

Answer 2

cd /var/cache/pacman/pkg/
pacman -U <file_name_of_the_package>

当然，你必须在那里有你想要的版本。

-> alexmina
"downgrade gcc"

您确定使用的是Archlinux吗？

Answer 3

您应该同时指定gcc和gcc-libs。例如，如果您想将7.1.1降级为6.3.1

方法1)

pacman -U /var/cache/pacman/pkg/gcc-6.3.1-2-x86_64.pkg.tar.xz /var/cache/pacman/pkg/gcc-libs-6.3.1-2-x86_64.pkg.tar.xz  

方法2)

downgrade gcc gcc-libs

并选择通缉版本。
