#include <stdio.h>

        printf("Hello, world!\n");

这里，源码中的 Makefile 支持 GNU 编码标准 和 FHS（文件系统层级规范）。特别地：

Makefile. 

 $ cat debhello-0.0/Makefile
prefix = /usr/local

all: src/hello

src/hello: src/hello.c
        @echo "CFLAGS=$(CFLAGS)" | \
                fold -s -w 70 | \
                sed -e 's/^/# /'
        $(CC) $(CPPFLAGS) $(CFLAGS) $(LDCFLAGS) -o $@ $^

install: src/hello
        install -D src/hello \
                $(DESTDIR)$(prefix)/bin/hello

clean:
        -rm -f src/hello

distclean: clean

uninstall:
        -rm -f $(DESTDIR)$(prefix)/bin/hello

.PHONY: all install clean distclean uninstall

	Note
	对 $(CFLAGS) 的 echo 命令用于在接下来的例子中验证所设置的构建参数。

	Tip
	如果 debmake 命令调用时使用了 -T 选项，程序将为模板文件产生更加详细的注释内容。

debmake 命令的输出十分详细，如下所示，它可以展示程序的具体操作内容。

debmake 命令基于命令行选项产生所有这些模板文件。如果没有指定具体选项，debmake 命令将为您自动选择合理的默认值：

• 源码包名称：debhello
• 上游版本：0.0
• 二进制软件包名称：debhello
• Debian 修订版本：1
• 软件包类型： bin（ELF 二进制可执行程序软件包）
• -x 选项：-x1（是单个二进制软件包的默认值）

我们来检查一下自动产生的模板文件。

这里的 debian/rules 文件是应当由软件包维护者提供的构建脚本。此时该文件是由 debmake 命令产生的模板文件。

debian/rules（模板文件）：. 

 $ cat debhello-0.0/debian/rules
#!/usr/bin/make -f
# You must remove unused comment lines for the released package.
#export DH_VERBOSE = 1
#export DEB_BUILD_MAINT_OPTIONS = hardening=+all
#export DEB_CFLAGS_MAINT_APPEND  = -Wall -pedantic
#export DEB_LDFLAGS_MAINT_APPEND = -Wl,--as-needed

%:
        dh $@

#override_dh_auto_install:
#       dh_auto_install -- prefix=/usr

#override_dh_install:
#       dh_install --list-missing -X.pyc -X.pyo

这便是使用 dh 命令时标准的 debian/rules 文件。（某些内容已被注释，可供后续修改使用。）

这里的 debian/control 文件提供了 Debian 软件包的主要元信息。此时该文件是由 debmake 命令产生的模板文件。

debian/control（模板文件）：. 

 $ cat debhello-0.0/debian/control
Source: debhello
Section: unknown
Priority: optional
Maintainer: "Firstname Lastname" <email.address@example.org>
Build-Depends: debhelper-compat (= 13)
Standards-Version: 4.5.1
Homepage: <insert the upstream URL, if relevant>
Rules-Requires-Root: no

Package: debhello
Architecture: any
Multi-Arch: foreign
Depends: ${misc:Depends}, ${shlibs:Depends}
Description: auto-generated package by debmake
 This Debian binary package was auto-generated by the
 debmake(1) command provided by the debmake package.

	Warning
	如果您对 debian/control 模板文件中的“Section: unknown”部分不做修改的话，后续的 lintian 错误可能导致构建失败。

因为这是个 ELF 二进制可执行文件软件包，debmake 命令设置了“Architecture: any”和“Multi-Arch: foreign”两项。同时，它将所需的 substvar 参数设置为“Depends: ${shlibs:Depends}, ${misc:Depends}”。这些内容将在 Chapter 5, 基本内容 部分进行解释。

	Note
	请注意这个 debian/control 按照“Debian政策手册”中 5.2 Source package control files — debian/control 的内容使用 RFC-822 风格进行编写。文件对空行和行首空格的使用有特别的要求。

这里的 debian/copyright 提供了 Debian 软件包版权数据的总结。此时该文件是由 debmake 命令产生的模板文件。

debian/copyright（模板文件）：. 

 $ cat debhello-0.0/debian/copyright

export DEB_LDFLAGS_MAINT_APPEND = -Wl,--as-needed

%:
        dh $@

override_dh_auto_install:
        dh_auto_install -- prefix=/usr

如上导出 DEB_BUILD_MAINT_OPTION 变量可以如 dpkg-buildflags(1) 手册页中“FEATURE AREAS/ENVIRONMENT”部分所说，对加固选项进行设置。^[9]

如上导出 DEB_CFLAGS_MAINT_APPEND 可以强制 C 编译器给出所有类型的警告内容。

如上导出 DEB_LDFLAGS_MAINT_APPEND 可以强制链接器只对真正需要的库进行链接。^[10]

对基于 Makefile 的构建系统来说，dh_auto_install 命令所做的基本上就是“$(MAKE) install DESTDIR=debian/debhello”。这里创建的 override_dh_auto_install 目标将其行为修改为“$(MAKE) install DESTDIR=debian/debhello prefix=/usr”。

在 debian/ 目录下还有一些其它的模板文件。它们也需要进行更新。

	Tip
	对于来自 debhelper 软件包的各个 dh_* 命令来说，它们在读取所使用的配置文件时通常把以 # 开头的行视为注释行。

您可以使用 debuild 或者等效的命令工具（参见 Section 4.4, “什么是 debuild？”）在这个源码树内构建一个非原生 Debian 软件包。命令的输出通常十分详细，如下所示，它会对构建中执行的操作进行解释。

 $ cd debhello-0.0
 $ debuild
 dpkg-buildpackage -us -uc -ui -i -i
 ...
 debian/rules clean
dh clean
 ...
 debian/rules binary

   dh_update_autotools_config
   dh_autoreconf
   dh_auto_configure
        install -d /path/to/debhello-0.0/debian/.debhelper/generated/_source/...
   dh_auto_build
        make -j12 "INSTALL=install --strip-program=true"
make[1]: Entering directory '/path/to/debhello-0.0'
# CFLAGS=-g -O2
# -ffile-prefix-map=/home/osamu/src/public/debmake-doc/debmake-doc/examp
 ...
Now running lintian -i -I --show-overrides debhello_0.0-1_amd64.changes ...
 ...
N:   Renamed from: binary-without-manpage
N:
W: debhello: readme-debian-contains-debmake-template
N:
 ...

这里验证了 CFLAGS 已经得到了更新，添加了 -Wall 和 -pendatic 参数；这是我们先前在 DEB_CFLAGS_MAINT_APPEND 变量中所指定的。

根据 lintian 的报告，您应该如同后文中的例子那样（请见 Chapter 8, 更多示例）为软件包添加 man 手册页。我们这里暂且跳过这部分内容。

现在我们来看看成果如何。

debhello 0.0 版使用 debuild 命令产生的文件：.

生成的所有二进制软件包的依赖列表（v=0.0）：. 

 $ dpkg -f debhello-dbgsym_0.0-1_amd64.deb pre-depends \
            depends recommends conflicts breaks
Depends: debhello (= 0.0-1)
 $ dpkg -f debhello_0.0-1_amd64.deb pre-depends \
            depends recommends conflicts breaks
Depends: libc6 (>= 2.2.5)

	Caution
	在将软件包上传至 Debian 仓库之前，仍然有很多细节需要进行处理。

	Note
	如果跳过了对 debmake 命令自动生成的配置文件的手工调整步骤，所生成的二进制软件包可能缺少有用的软件包描述信息，某些政策的要求也无法满足。这个不正式的软件包对于 dpkg 命令来说可以正常处理，也许这样对您本地的部署来说已经足够好了。

打包操作基本上和上面的分步示例相同，除了在 Section 4.7, “第三步：编辑模板文件” 中的两点：

这个使用一系列补丁文件进行 Debian 打包的备选方案对于应对上游未来的改变可能不够健壮，但是在应对更为复杂的上游源代码时可以更灵活。（参见 Section 7.13, “3.0 源代码格式”。）

	Note
	对当前这个特定的打包场景，前文的 Section 4.7, “第三步：编辑模板文件” 中使用 debian/rules 文件的方式更好一些。但为了演示起见，此时我们先使用本节的方式继续操作。

	Tip
	对更复杂的打包场景，可能需要同时应用 Section 4.7, “第三步：编辑模板文件” 和 Section 4.9, “第三步（备选）：修改上游源代码” 中的方式。

4.9.2. 使用 dquilt 处理补丁

这里的例子使用 dquilt 命令（一个 quilt 程序的简单封装）创建 000-prefix-usr.patch。dquilt 命令的语法和功能与 quilt(1) 命令相同，唯一的区别在于补丁存储在 debian/patches/ 目录中。

 $ cd debhello-0.0

这里，上游源码树中的 Makefile 文件没有恢复到原始状态的必要。在 Section 4.8, “第四步：使用 debuild 构建软件包” 描述的 Debian 打包过程中调用的 dpkg-source 命令能够理解由 dquilt 程序在 .pc/ 目录中记录的补丁应用情况。只要所有这些修改都是由 dquilt 命令完成的，那么 Debian 源码包就可以从经过修改的源码树中进行构建。

	Note
	如果 .pc/ 目录不存在，dpkg-source 命令就会假定没有应用任何补丁。这就是更为原始的补丁生成方法，例如 Section 4.9.1, “使用 diff -u 处理补丁” 中未生成 .pc/ 目录的情况下要求将上游源码树进行恢复的原因。
