Description

This library is needed to unpack installers in the .7z format.

Resolution

On CrossOver 17 and greater, the simplest solution to fix this issue is to run:

/path/to/cxoffice/bin/cxfix missinglibstdc missinglibstdc.amd64

Or add --show-all to see how CrossOver would fix it on your platform and others.

Alternatively you may try one of the commands below.

• For 32-bit Windows applications
  32-bit Arch Linux : pacman -Syu gcc-libs
  64-bit Arch Linux : pacman -Syu lib32-gcc-libs
  Debian : apt-get install libstdc++6:i386
  32-bit Fedora : yum install libstdc++
  64-bit Fedora : yum install libstdc++.i686 libstdc++.x86_64
  32-bit openSUSE >= 11.2 : zypper install libstdc++44
  64-bit openSUSE >= 11.2 : zypper install libstdc++44-32bit
  32-bit openSUSE >= 11.3 : zypper install libstdc++45
  64-bit openSUSE >= 11.3 : zypper install libstdc++45-32bit
  32-bit openSUSE >= 12.1 : zypper install libstdc++47
  64-bit openSUSE >= 12.1 : zypper install libstdc++47-32bit
  32-bit openSUSE >= 12.3 : zypper install libstdc++6
  64-bit openSUSE >= 12.3 : zypper install libstdc++6-32bit
• For 64-bit Windows applications
  Arch Linux : pacman -Syu gcc-libs
  Debian : apt-get install libstdc++6:amd64
  Fedora : yum install libstdc++.x86_64
  openSUSE >= 11.2 : zypper install libstdc++44
  openSUSE >= 11.3 : zypper install libstdc++45
  openSUSE >= 12.1 : zypper install libstdc++47
  openSUSE >= 12.3 : zypper install libstdc++6

Notes:

• cxfix --show-all may have more up-to-date fixes.
• The commands usually also apply to newer versions of the distributions above as well as derived distributions. So for instance a fix for Debian 7 may still be valid for the latest Debian Testing and is typically also applicable to Ubuntu, Linux Mint, Deepin and Pop! OS. Similarly a fix for Fedora likely also works on Red Hat Enterprise Linux, CentOS, etc.
