GCC

GCC 的意思也只是 GNU C Compiler 而已。經(jīng)過了這么多年的發(fā)展，GCC 已經(jīng)不僅僅能支持 C 語言；它現(xiàn)在還支持 Ada 語言、C++ 語言、Java 語言、Objective C 語言、Pascal 語言、COBOL語言，以及支持函數(shù)式編程和邏輯編程的 Mercury 語言，等等。而 GCC 也不再單只是 GNU C 語言編譯器的意思了，而是變成了 GNU Compiler Collection 也即是 GNU 編譯器家族的意思了。另一方面，說到 GCC 對于操作系統(tǒng)平臺及硬件平臺支持，概括起來就是一句話：無所不在

make

無論是在Linux還是在UNIX環(huán)境中，make都是一個非常重要的編譯工具。無論是自己進行項目開發(fā)還是安裝應(yīng)用軟件，都需要使用make工具。利用make工具，可以將大型的開發(fā)項目分解成為多個更易于管理的模塊，對于一個包括幾百個源文件的應(yīng)用程序而言，使用make工具和makefile文件就可以清晰地理順各個源文件之間的關(guān)系。而且如此多的源文件，如果每次都要輸入gcc命令進行編譯的話，對程序員來說是很難忍受的。make工具可以自動完成編譯工作，并且只對程序員在上次編譯后修改過的部分進行編譯。因此，有效地利用make工具可以大大提高項目開發(fā)的效率

程序包編譯

上圖就是編譯的過程
程序包編譯安裝：
Application-VERSION-release.src.rpm --> 安裝后
使用用rpmbuild 命令制作成二進制格式的rpm 包，而后再安裝
源代碼--> 預(yù)處理--> 編譯--> 匯編--> 鏈接--> 執(zhí)行
源代碼組織格式：
多文件：文件中的代碼之間，很可能存在跨文件依賴關(guān)系
C 、C++ ：make 項目管理器
configure --> Makefile.in --> makefile
java: mave
下面開始安裝包組里面集成了make和GCC

安裝包組

編譯C 源代碼：
- 準備：提供開發(fā)工具及開發(fā)環(huán)境
- 開發(fā)工具：make, gcc等等
- 開發(fā)環(huán)境：開發(fā)庫，頭文件
- glibc ：標準庫
- 實現(xiàn)：通過“包組”提供開發(fā)組件
- Development Tools
- Server Platform Development

Development Tools
- Development Tools里面有幾十個，大家主要使用其中的gcc, make等編譯工具

首先我們要測試是否配好了yum 源，可以用yum list|grep 來測試

[root@localhost ~]# yum list|grep httpd
httpd.x86_64                               2.4.6-45.el7.centos         bash     
httpd-devel.x86_64                         2.4.6-45.el7.centos         bash     
httpd-manual.noarch                        2.4.6-45.el7.centos         bash     
httpd-tools.x86_64                         2.4.6-45.el7.centos         bash     
libmicrohttpd.i686                         0.9.33-2.el7                bash     
libmicrohttpd.x86_64                       0.9.33-2.el7                bash     
libmicrohttpd-devel.i686                   0.9.33-2.el7                bash     
libmicrohttpd-devel.x86_64                 0.9.33-2.el7                bash     
libmicrohttpd-doc.noarch                   0.9.33-2.el7                bash

yum源配好了以后我們來查找包組可以用yum grouplist來查詢包組

[root@localhost ~]# yum grouplist

   Console Internet Tools

   Legacy UNIX Compatibility
   Scientific Support
   Security Tools

那我們來開始安裝Development Tools包組，可以用命令yum install Development Tools來安裝包組

[root@localhost yum.repos.d]# yum clean all                    
Loaded plugins: fastestmirror, langpacks
Cleaning repos: bash epel
Cleaning up everything
Cleaning up list of fastest mirrors

(6/6): bash/group_gz

安裝包組以后開始找到源碼包可以上傳也可以去包里面下載我這里用httpd-2.4.25.tar.bz2源碼包做演示
首先解壓httpd-2.4.25.tar.bz2包，可以用tar -xf命令來解壓

[root@localhost /]# tar -vxf  httpd-2.4.25.tar.bz2 
httpd-2.4.25/support/suexec.h
httpd-2.4.25/support/win32/
httpd-2.4.25/support/win32/apache_header.bmp
httpd-2.4.25/support/win32/ApacheMonitor.c
httpd-2.4.25/support/win32/ApacheMonitor.dep
httpd-2.4.25/support/win32/ApacheMonitor.dsp
httpd-2.4.25/support/win32/ApacheMonitor.h
httpd-2.4.25/support/win32/ApacheMonitor.ico
httpd-2.4.25/support/win32/ApacheMonitor.mak
httpd-2.4.25/support/win32/ApacheMonitor.manifest
httpd-2.4.25/support/win32/ApacheMonitor.rc
httpd-2.4.25/support/win32/aprun.ico

下面httpd-2.4.25就是我們解壓的文件目錄用cd切換到httpd-2.4.25目錄里面

[root@localhost /]# ls
bin   dev  home          httpd-2.4.25.tar.bz2  lib64  mnt  proc  run   srv  tmp  var
boot  etc  httpd-2.4.25  lib                   media  opt  root  sbin  sys  usr

我們來看下httpd-2.4.25目錄里面有什么，想就是httpd-2.4.25所有文件

[root@localhost httpd-2.4.25]# ls
ABOUT_APACHE     build           config.layout  httpd.dsp       LAYOUT        Makefile.win   README.cmake      test

Apache-apr2.dsw  BuildBin.dsp    configure.in   httpd.spec      libhttpd.dsp  NOTICE         ROADMAP
Apache.dsw       buildconf       docs           include         libhttpd.mak  NWGNUmakefile  server
apache_probes.d  CHANGES         emacs-style    INSTALL         LICENSE       os             srclib
ap.d             CMakeLists.txt  httpd.dep      InstallBin.dsp  Makefile.in   README         support

下面我們就開始編譯測試安裝了可以用configure來測試用--prefix=/PATH: 指定默認安裝位置, 默認為/usr/local/

[root@localhost httpd-2.4.25]# ./configure  --prefix=/app

編譯開始，編譯過程中可能會遇到很多問題下面請看

[root@localhost httpd-2.4.25]# ./configure  --prefix=/app

configure: 
checking for APR... no
configure: error: APR not found.  Please read the documentation.

遇到一個錯誤說要APR包，我們可以用yum search apr來查包

[root@localhost httpd-2.4.25]# yum  search apr
apr-devel.i686 : APR library development kit   《《《《《《《這個就是我們的APR包
apr-devel.x86_64 : APR library development kit

apr-util-pgsql.x86_64 : APR utility library PostgreSQL DBD driver
apr-util-sqlite.x86_64 : APR utility library SQLite DBD driver

我們只需要安裝包即可用命令yum install apr-devel來安裝
安裝完畢以后又來編譯測試看他還報錯不 ./configure --prefix=/app
又出現(xiàn)了錯誤error: APR-util not found. Please read the documentation.

[root@localhost httpd-2.4.25]# ./configure  --prefix=/app

configure:

configure: error: APR-util not found.  Please read the documentation.

我們繼續(xù)找APR-util包一樣的命令yum search APR-util

[root@localhost httpd-2.4.25]# yum  search APR-util
apr-util.i686 : Apache Portable Runtime Utility library
apr-util.x86_64 : Apache Portable Runtime Utility library
apr-util-devel.i686 : APR utility library development kit

apr-util-pgsql.x86_64 : APR utility library PostgreSQL DBD driver
apr-util-sqlite.x86_64 : APR utility library SQLite DBD driver

安裝完畢以后在用yum search apr來查包
出現(xiàn)pcre-config 錯誤

configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

-在來找pcre-config包,辦法一樣

[root@localhost httpd-2.4.25]# yum  search pcre
pcre-devel.i686 : Development files for pcre  《《這個包
pcre-devel.x86_64 : Development files for pcre
pcre-static.i686 : Static library for pcre
pcre-static.x86_64 : Static library for pcre
pcre-tools.x86_64 : Auxiliary utilities for pcre
pcre.i686 : Perl-compatible regular expression library
pcre.x86_64 : Perl-compatible regular expression library

安裝完畢以后在查包，不過我這里已經(jīng)測試編譯完畢出現(xiàn)下面畫面

Server Version: 2.4.25
Install prefix: /app
C compiler:     gcc -std=gnu99
CFLAGS:           -pthread
LDFLAGS:         
LIBS:           
CPPFLAGS:        -DLINUX -D_REENTRANT -D_GNU_SOURCE
C preprocessor: gcc -E

那我們開始編譯，上面只是測試編譯，現(xiàn)在開始正式編譯
用到的工具是make編譯必須在解壓的路徑才有效果切記切記
開始編譯：出現(xiàn)下面畫面就表示

[root@localhost httpd-2.4.25]# make

出現(xiàn)下面畫面表示編譯完成

 -avoid-version  mod_rewrite.lo 
make[4]: Leaving directory `/httpd-2.4.25/modules/mappers'
make[3]: Leaving directory `/httpd-2.4.25/modules/mappers'
make[2]: Leaving directory `/httpd-2.4.25/modules'
make[2]: Entering directory `/httpd-2.4.25/support'
make[2]: Leaving directory `/httpd-2.4.25/support'

make[1]: Leaving directory `/httpd-2.4.25'

那我們開始安裝可以用命令make install來安裝

[root@localhost httpd-2.4.25]# make install

出現(xiàn)下面畫面就表示安裝完成

Installing configuration files
mkdir /app/conf
mkdir /app/conf/extra
mkdir /app/conf/original
mkdir /app/conf/original/extra
Installing HTML documents
mkdir /app/htdocs
Installing error documents
mkdir /app/error

mkdir /app/icons
mkdir /app/logs
Installing CGIs
mkdir /app/cgi-bin
Installing header files

Installing man pages and online manual
mkdir /app/man
mkdir /app/man/man1
mkdir /app/man/man8
mkdir /app/manual
make[1]: Leaving directory `/httpd-2.4.25'

就表示我們軟件已經(jīng)編譯安裝完成需要開啟服務(wù)，就可以用了
