在 Debian Squeeze 64x 上安裝 gcc 4.7.2
我想在我的 Debian Squeeze 64x 上使用 gcc 4.7.2
我按照這個執行緒中的說明進行操作：Get latest gcc for debian? ，但出現錯誤，我嘗試了幾個 apt-get install 命令
只要我可以使用新的 c++ 11 功能，我就會選擇 4.7.1。
以下是我更新的來源列表和首選項文件。更新這些文件後，我從根終端使用 apt-get update。
/etc/apt/sources.list

Package: * Pin: release n=squeeze Pin-Priority: 900 Package: * Pin: release n=wheezy Pin-Priority: 200似乎這有所幫助，但現在 apt-get 抱怨未滿足的依賴關係

gcc-4.7.2 於 3 天前的 9 月 20 日發布。
它還沒有進入 debian repos（請參閱 update2，感謝 derobert）。根據發行說明，這是一個修復錯誤的版本，因此可能會使用與之前的 4.7.1 版本相同的庫版本。因此，由於 4.7.1 在 repos 中，安裝它以對所有依賴項進行排序，然後如果您真的需要最新版本，請下載原始碼並按照gcc 網站的說明進行編譯。
更新：
您的 source.lst 似乎有問題。作為一種解決方法，請嘗試在此處下載軟體包並使用
dkpg -i gcc_4.7.1-1_amd64.deb.更新 2：
正如@derobert 在下面指出的那樣，4.7.2 確實在實驗性儲存庫中。因此，請調整您連結到的文章中的說明：
你
/etc/apt/sources.list應該看起來像這樣：deb *local.debian.mirror*擠壓主要 deb *local.debian.mirror*不穩定主雖然你
/etc/apt/preferences應該看起來像這樣：包裹： * 引腳：釋放 n=擠壓 引腳優先級：900 包裹： * 引腳：釋放 n=unstable 引腳優先級：200然後使用
apt-get install gcc-4.7/unstable.正如 jordanm 和您提到的原始教程一樣，這不是一個好主意。完成後，請確保將您的資源指向穩定。
