从Linux上的来源构建Haskell GHC

似乎有一个循环依赖性建立GHC时：

$ wget https://downloads.haskell.org/~ghc/9.2.2/ghc-9.2.2-src.tar.xz
$ tar -xf ghc-9.2.2-src.tar.xz
$ cd ghc-9.2.2/
$ sed -n "11,12p" INSTALL.md 
N.B. in particular you need GHC installed in order to build GHC,
because the compiler is itself written in Haskell.  For instructions
$ sudo apt install ghc # <----- somehow get an older version to build from source the new one
$ ./configure 
checking for gfind... no
checking for find... /usr/bin/find
checking for sort... /usr/bin/sort
checking for GHC Git commit id... given fbaee70d380973f71fa6e9e15be746532e5a4fc5
checking for ghc... /usr/bin/ghc
checking version of ghc... 8.6.5
configure: error: GHC version 8.10 or later is required to compile GHC. # ???!!!

为了构建新的GHC，需要一些 旧版本的GHC版本，但是不太旧。 apt-get版本太旧了。有什么想法吗？

It seems there is a circular dependency when building ghc:

$ wget https://downloads.haskell.org/~ghc/9.2.2/ghc-9.2.2-src.tar.xz
$ tar -xf ghc-9.2.2-src.tar.xz
$ cd ghc-9.2.2/
$ sed -n "11,12p" INSTALL.md 
N.B. in particular you need GHC installed in order to build GHC,
because the compiler is itself written in Haskell.  For instructions
$ sudo apt install ghc # <----- somehow get an older version to build from source the new one
$ ./configure 
checking for gfind... no
checking for find... /usr/bin/find
checking for sort... /usr/bin/sort
checking for GHC Git commit id... given fbaee70d380973f71fa6e9e15be746532e5a4fc5
checking for ghc... /usr/bin/ghc
checking version of ghc... 8.6.5
configure: error: GHC version 8.10 or later is required to compile GHC. # ???!!!

So to build a new ghc, some older version of ghc is needed, but not too old.
The apt-get version is too old. Any ideas?

根据@Daniel Wagner的评论发布自我完整性：

$ wget https://downloads.haskell.org/~ghc/9.2.2/ghc-9.2.2-x86_64-ubuntu20.04-linux.tar.xz
$ tar -xf ghc-9.2.2-x86_64-ubuntu20.04-linux.tar.xz
$ cd ghc-9.2.2/
$ ./configure # <----- you still have to do configre + make
$ make
$ sudo make install
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 9.2.2

Posting for self completeness according to the comment of @Daniel Wagner:

$ wget https://downloads.haskell.org/~ghc/9.2.2/ghc-9.2.2-x86_64-ubuntu20.04-linux.tar.xz
$ tar -xf ghc-9.2.2-x86_64-ubuntu20.04-linux.tar.xz
$ cd ghc-9.2.2/
$ ./configure # <----- you still have to do configre + make
$ make
$ sudo make install
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 9.2.2
