git-core 原始碼安裝

今天想弄一個git裝，發現公司無法訪問官網。

回家也發現官網一直無法登陸，後來搞到要上梯子……

最後發現竟然就是公司裡可以訪問的google code

git安裝依賴
(INSTALL)檔案說

zlib ,ssh, openssl perl 基本必須的，應該也都有，其它都可以忽略。

- "zlib", the compression library. Git won't build without it.

- "ssh" is used to push and pull over the net.

- A POSIX-compliant shell is required to run many scripts needed
for everyday use (e.g. "bisect", "pull").

- "Perl" version 5.8 or later is needed to use some of the
features (e.g. preparing a partial commit using "git add -i/-p",
interacting with svn repositories with "git svn"). If you can
live without these, use NO_PERL.

- "openssl" library is used by git-imap-send to use IMAP over SSL.
If you don't need it, use NO_OPENSSL.

By default, git uses OpenSSL for SHA1 but it will use it's own
library (inspired by Mozilla's) with either NO_OPENSSL or
BLK_SHA1. Also included is a version optimized for PowerPC
(PPC_SHA1).

- "libcurl" library is used by git-http-fetch and git-fetch. You
might also want the "curl" executable for debugging purposes.
If you do not use http:// or https:// repositories, you do not
have to have them (use NO_CURL).

- "expat" library; git-http-push uses it for remote lock
management over DAV. Similar to "curl" above, this is optional
(with NO_EXPAT).

- "wish", the Tcl/Tk windowing shell is used in gitk to show the
history graphically, and in git-gui. If you don't want gitk or
git-gui, you can use NO_TCLTK.
