1.下載源碼
首先，從github上下載protobuf的源碼，地址：https://github.com/google/protobuf,我選擇下載2.5.0版本。
2.編譯protobuf
將下載的壓縮包解壓縮
unzip protobuf-2.5.0.zip
根目錄下沒有configure文件，卻有一個autogen.sh，原來是因為protobuf的編譯方式做了修改，要執行autogen.sh才會生成configure腳本。
但在執行autogen.sh時出錯了，因為google.com被牆了，虛擬機里無法下載gtest，於是手動下載googletest-release-1.5.0.zip,解壓縮后，改名為gtest放在protobuf-2.5.0目錄下
autgen.sh代碼片段
1 # Check that gtest is present. Usually it is already there since the 2 # directory is set up as an SVN external. 3 # 判斷是否存在gtest目錄 4 if test ! -e gtest; then 5 echo "Google Test not present. Fetching gtest-1.5.0 from the web..." 6 #如果目錄不存在則嘗試從google.com下載並解壓縮，如果google被牆則下載失敗 7 curl http://googletest.googlecode.com/files/gtest-1.5.0.tar.bz2 | tar jx 8 #將解壓縮后的目錄改名為gtest 9 mv gtest-1.5.0 gtest 10 fi
googletest1.5.0下載地址:https://github.com/google/googletest
解壓縮
1 unzip gtest-1.5.0.zip 2 mv gtest-1.5.0 gtest
執行protobuf編譯
#執行autogen.sh生成configure
又是一堆的錯誤！！！ 運行./autogen.sh時（用於產生configure,） 出現錯誤：
1 linux-lewph:/home/lewph/Projects/System/build_tslib/tslib # ./autogen.sh 2 ./autogen.sh: line 4: autoreconf: command not found
缺少autoconf這個工具安裝：
1 yum install -y autoconf
再次運行./autogen.sh問題又來了：
1 linux-lewph:/home/lewph/Projects/System/build_tslib/tslib # ./autogen.sh 2 Can't exec "aclocal": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 326. 3 autoreconf: failed to run aclocal: No such file or directory
1 linux-lewph:/home/lewph/Projects/System/build_tslib/tslib # ./autogen.sh 2 Can't exec "aclocal": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 326. 3 autoreconf: failed to run aclocal: No such file or directory 有這個文件，推測，問題出現在exec "aclocal"這里，
用cnf查一下，linux-lewph:/home/lewph/Projects/System/build_tslib/tslib # cnf aclocal
The program 'aclocal' can be found in following packages: * automake [ path: /usr/bin/aclocal, repository: zypp (repo-oss) ] * automake [ path: /usr/bin/aclocal, repository: zypp (openSUSE 11.2-0) ]
安裝依賴
1 yum install automake
原來是要用到automake這個工具！安裝之！完成以后，再運行./autogen.sh . 問題還有！！！:
1 linux-lewph:/home/lewph/Projects/System/build_tslib/tslib # ./autogen.sh 2 configure.ac:25: error: possibly undefined macro: AC_DISABLE_STATIC 3 If this token and others are legitimate, please use m4_pattern_allow. 4 See the Autoconf documentation. 5 configure.ac:26: error: possibly undefined macro: AC_ENABLE_SHARED 6 configure.ac:27: error: possibly undefined macro: AC_LIBTOOL_DLOPEN 7 configure.ac:28: error: possibly undefined macro: AC_PROG_LIBTOOL 8 autoreconf: /usr/bin/autoconf failed with exit status: 1
這是缺少安裝包libtool-1.5.22.tar.gz 安裝
yum install -y libtool
3.安裝protobuf
1 ./autogen.sh 2 ./configure
1 make 2 make check
1 sudo make install
4.成功
