Delphi命令行编译指南

1、 HYPERLINK /tarmee/archive/2007/08/02/1722299.aspx Delphi命令行编译指南Borland出品的Delphi，有着闪电般的编译速度，但是在界面控件使用较多、工程项目较大的时候，编译一个工程仍需要一段时间，打开庞大的Delphi IDE，也需要时间。其实，在一个工程开发结束，调试完成之后的Release编译，完全可以用命令行来执行，因为Delphi的编译器参数不像C+编译器那样复杂。笔者把Delphi联机手册中关于命令行编译(command-line compiler)的几篇主题作了翻译，希望对Delphi开发人员有帮助。目录 HYPERLIN

8、译器Delphis command-line compiler (dcc32.EXE) lets you invoke all the functions of the IDE compiler (DELPHI32.EXE) from the DOS command line (see IDE command-line options. Run the command-line compiler from the DOS prompt using the syntax:Delphis命令行编译器(dcc32.exe)允许你从DOS命令行方式(参照：IDE命令行选项)实现IDE编译器(delph

9、i32.exe)的所有功能。用DOS命令运行命令行编译器语法如下：dcc32 options filename optionsdcc32 选项 文件名 选项where options are zero or more parameters that provide information to the compiler and filename is the name of the source file to compile. If you type dcc32 alone, it displays a help screen of command-line options and synt

10、ax.零或多个参数给编译器提供信息，文件名指定需要编译的源文件名。如果你单独输入dcc32，它会显示一个关于命令行编译的选项和语法的屏幕。If filename does not have an extension, the command-line compiler assumes .dpr, then .pas, if no .dpr is found. If the file youre compiling to doesnt have an extension, you must append a period (.) to the end of the filename.如果文件名没

11、有扩展名，命令行编译器会查找扩展名为.dpr的同名文件，如果找不到，则查找扩展名为.pas的同名文件。如果你的源文件确实没有扩展名，你需要在文件名的末尾添加(.)。If the source text contained in filename is a program, the compiler creates an executable file named filename.EXE. If filename contains a library, the compiler creates a file named filename.DLL. If filename contains a

12、package, the compiler creates a file named filename.BPL. If filename contains a unit, the compiler creates a unit file named filename.dcu.如果指定的源文件是一个工程文件，编译器会创建一个扩展名为.EXE的同名可执行文件。如果指定的源文件是一个库文件，编译器创建一个扩展名为.DLL的同名动态链接库文件。如果指定的源文件是一个包文件，编译器会创建一个扩展名为.BPL的同名包。如果指定的源文件是一个单元文件，编译器会创建一个扩展名为.dcu的目标代码文件。You

13、can specify a number of options for the command-line compiler. An option consists of a slash (/) orimmediately followed by an option letter. In some cases, the option letter is followed by additional information, such as a number, a symbol, or a directory name. Options can be given in any order and

14、can come before or after the file name.你可以为命令行编译器指定多个参数。一个参数包含一个破折号“-”(或“/”)和紧跟着的一个选项字符构成。通常情况下，选项字符后面会跟一些附加的信息，如一个数字、一个符号、一个目录等。选项可以是任意顺序并且可以在源文件名前面或后面。2 Command-line compiler options命令行编译选项The IDE lets you set various options through the menus; the command-line compiler gives you access to these o

15、ptions using the slash (/) delimiter. You can also precede options with a hyphen (-) instead of a slash (/), but those options that start with a hyphen must be separated by blanks. For example, the following two command lines are equivalent and legal:IDE允许你使用菜单来设置各种编译选项，而命令行编译器允许你使用字符“/”作为分隔符来设定这些编译

16、选项。你也可以使用连字符“-”来代替“/”，但是用“-”引出的参数之间必须用空格隔开。例如，下面两个命令都是等同的也是合法的：DCC -IC:DELPHI -DDEBUG SORTNAME -$R- -$U+DCC /IC:DELPHI/DDEBUG SORTNAME /$R-/$U+The first command line uses hyphens with at least one blank separating options. The second uses slashes and no separation is needed.第一个编译命令用“-”引出参数，且参数之间有多个空

17、格分隔。第二个编译命令用“/”引出参数，参数之间不必要分隔。The following table lists the command-line options. In addition to the listed options, all single-letter compiler directives can be specified on the command line, as described in Compiler directive options.下列表中列出所有的命令行参数。在附加的选项列表中，所有的单字符编译器指令都可以在命令行编译中使用，详情请参照：编译器指令。Opt

20、rsion 显示产品名称和版本3 Compiler directive options编译器指令选项Delphi supports the compiler directives described in Compiler directives. The $ and D command-line options allow you to change the default states of most compiler directives. Using $ and D on the command line is equivalent to inserting the correspond

21、ing compiler directive at the beginning of each source file compiled.Delphi支持用编译器指令关键字描述的编译器指令。使用“$”和“D”命令行选项可以改变所有的默认编译器状态。用“$”和“D”命令行选项等同于在源文件的前面添加编译器指令。Switch directive option编译器指令选项开关The $ option lets you change the default state of all of the switch directives. The syntax of a switch directive

22、option is $ followed by the directive letter, followed by a plus (+) or a minus (-). For example:“$”允许你改变每一种编译器指令默认状态。编译器指令的语法是“$”后紧跟一个指令字符，再跟一个“-”或“+”。例如：dcc32 MYSTUFF -$R-compiles MYSTUFF.pas with range-checking turned off, while:不使用边界检查编译MYSTUFF.pas单元：dcc32 MYSTUFF -$R+compiles it with range chec

23、king turned on. Note that if a $R+ or $R- compiler directive appears in the source text, it overrides the -$R command-line option.使用界面检查编译MYSTUFF.pas单元。如果将编译器指令$R+或$R-添加到源文件的开始，它将覆盖从命令行传入的参数。You can repeat the -$ option in order to specify multiple compiler directives:你可以用多个“$”来指定多个编译器指令，如：dcc32 MYS

24、TUFF -$R-$I-$V-$U+Alternately, the command-line compiler lets you write a list of directives (except for $M), separated by commas:命令行编译器允许作用逗号分隔的编译器指定列表，如：dcc32 MYSTUFF -$R-,I-,V-,U+只需要用一个“$”符号。Only one dollar sign ($) is needed.注意，因为$M的格式不一样，你不能在逗号分隔的指令列表中使用$MNote that, because of its format, you c

25、annot use the $M directive in a list of directives separated by commas.Conditional defines option条件编译选项The -D option lets you define conditional symbols, corresponding to the $DEFINE symbol compiler directive. The -D option must be followed by one or more conditional symbols separated by semicolons

26、(;). For example, the following command line:“-D”选项允许你定义一个编译条件，符合你用$DEFINE symbol定义的编译器指令。“-D”选项后必须跟随一或多个用分号分隔的编译条件符号，如下命令：dcc32 MYSTUFF -DIOCHECK;DEBUG;LISTdefines three conditional symbols, iocheck, debug, and list, for the compilation of MYSTUFF.pas. This is equivalent to inserting:定义了三个编译条件符号：IO

27、CHECK,DEBUG,LIST,用于MYSTUFF.pas单元中。这等同于在源文件中插入以下语句：$DEFINE IOCHECK$DEFINE DEBUG$DEFINE LISTat the beginning of MYSTUFF.pas. If you specify multiple -D directives, you can concatenate the symbol lists. Therefore:如果你指定了多个“-D”选项，你可以联接它们，如下：dcc32 MYSTUFF -DIOCHECK-DDEBUG-DLISTis equivalent to the first e

28、xample.等同于第一个例子。4 Compiler mode options编译模式选项A few options affect how the compiler itself functions. As with the other options, you can use these with either the hyphen or the slash format. Remember to separate the options with at least one blank.有几个选项能影响编译器自身的功能。像其它选项一个，你可以使用“/”或“-”的格式。别忘了用至少一个空格分隔

29、这些选项。Make (-M) option选项(-M)The command-line compiler has built-in MAKE logic to aid in project maintenance. The -M option instructs command-line compiler to check all units upon which the file being compiled depends. Using this option results in a much quicker compile time.命令行编译器使用构造逻辑的方式来维护工程。“-M”选

30、项指示编译器检查所有与编译文件相关联的文件。用这个参数会导致编译时间增大。 A unit is recompiled under the following conditions:一个源文件在下列情况下会重新编译：The source file for that unit has been modified since the unit file was created.源文件被创建以来被修改过；用“$I”指令包含的任何文件，用“$L”包含的任何.Obj文件，或用“$R”关联的任何资源文件.Res,比源文件中的要新；Any file included with the $I directive

31、, any .OBJ file linked in by the $L directive, or any .res file referenced by the $R directive, is newer than the unit file.The interface section of a unit referenced in a uses statement has changed.单元接口部分interface的uses段有改动。Units compiled with the -Z option are excluded from the make logic.在单元编译时指令“

32、-Z”在构造逻辑期不被接受。If you were applying this option to the previous example, the command would be:如果你在上一个例子中使用这个指令，编译命令就应该是：dcc32 MYSTUFF -MBuild all (-B) option编译所有 选项(-B)Instead of relying on the -M option to determine what needs to be updated, you can tell command-line compiler to update all units upo

33、n which your program depends using the -B option. You cant use -M and -B at the same time. The -B option is slower than the -M option and is usually unnecessary.用于取代要知道哪些单元需要更新-M的选项，你可以使用-B选项来更新所有你的程序中关联的单元。你不能在程序中同时使用-M和-B。选项-B比-M速度更慢，而且它并不是必需的。If you were using this option in the previous example,

34、 the command would be如果你在前一个例子中使用这个参数，编译命令就应该是：dcc32 MYSTUFF -BFind error (-F) option查找错误 选项(-F)When a program terminates due to a runtime error, it displays an error code and the address at which the error occurred. By specifying that address in a -Faddress option, you can locate the statement in t

35、he source text that caused the error, provided your program and units were compiled with debug information enabled (via the $D compiler directive).当一个程序由于运行期间错误而终止时，它会显示一个错误号和错误地址在错误发生时。用-Faddress选项来指定错误地址，你在源文件中能找到引发错误的位置，如果你的程序和单元编译时附加了调试信息(使用$D编译器指令)。In order for the command-line compiler to find

36、 the runtime error with -F, you must compile the program with all the same command-line parameters you used the first time you compiled it.为了命令行编译器能用-F选项查找运行期间错误，你必须传递与第一次编译时相同的指令列表。As mentioned previously, you must compile your program and units with debug information enabled for the command-line c

37、ompiler to be able to find runtime errors. By default, all programs and units are compiled with debug information enabled, but if you turn it off, using a $D- compiler directive or a -$D- option, the command-line compiler will not be able to locate runtime errors.先前提到过，你的程序和单元必须启用调试信息，命令行编译器才能查找运行期间

38、错误。默认情况下，所有的程序和单都是启用调试信息的，除非你用-D或-$D-指令关闭它，这样，命令行编译器就不能查找运行期间错误了。Use packages (-LU) option使用包(-LU)选项Use the -LU option to list additional runtime packages that you want to use in the application being compiled. Runtime packages already listed in the Project Options dialog box need not be repeated on

39、 the command line.使用-LU选项来在编译时添加你应用程序中要用到的运行期间包。运行期间包已经在“工程选项”对话框中列举的，不必再在命令行中添加。Disable implicit compilation (-Z) option(此选项在delphi6.0/7.0中有不同描述，在此不作翻译)The -Z option prevents packages and units from being implicitly recompiled later. With packages, it is equivalent to placing $ IMPLICITBUILD OFF in

40、 the .dpk file. Use -Z when compiling packages that provide low-level functionality, that change infrequently between builds, or whose source code will not be distributed.Target file extension (-TX) option目标文件扩展名(-TX)选项The -TX option lets you override the default extension for the output file. For e

41、xample,选项-TX允许你改写默认的输出文件扩展名。例如：dcc32 MYSTUFF -TXSYS generates compiled output in a file called MYSTUFF.SYS.生成的将是一个叫做MYSTUFF.SYS的文件。Quiet (-Q) option安静模式(-Q)选项The quiet mode option suppresses the printing of file names and line numbers during compilation. When the command-line compiler is invoked wit

42、h the quiet mode option安静模式选项禁止在编译时显示文件名及代码行数，如果命令行编译器调用这个选项的话。dcc32 MYSTUFF -Qits output is limited to the startup copyright message and the usual statistics at the end of compilation. If any errors occur, they will be reported.它的输出仅限于起始时行版权信息以及结尾的统计信息。当然，如果发生错误，它也会输出。5 DCC32.CFG fileDCC32.CFG配置文件Y

43、ou can set up a list of options in a configuration file called DCC32.CFG, which will then be used in addition to the options entered on the command line. Each line in configuration file corresponds to an extra command-line argument inserted before the actual command-line arguments. Thus, by creating

44、 a configuration file, you can change the default setting of any command-line option.你可以设置一个编译选项列表到一个叫做DCC32.CFG的配置文件中，它将用于编译时附加到命令行参数后。配置文件的每一行都相当于一个额外的命令行参数插入到实际的命令行参数前(注意，是实际参数前)。因而，你可以使用这个配置文件改变一些命令行参数的默认设置。The command-line compiler lets you enter the same command-line option several times, igno

45、ring all but the last occurrence. This way, even though youve changed some settings with a configuration file, you can still override them on the command line.命令行编译器允许你输入相同的命令行参数，它将忽略所有除最后一个之外。这个的话，尽管通过配置文件你可以改变一些设置，你仍然可以覆盖它使用命令行参数。When dcc32 starts, it looks for DCC32.CFG in the current directory.

46、If the file isnt found there, dcc32 looks in the directory where DCC32.EXE resides.当dcc32启动时，它查找DCC32.CFG文件在当前目录。如果文件没有找到，dcc32会查找它所在的目录。Heres an example DCC32.CFG file, defining some default directories for include, object, and unit files, and changing the default states of the $O and $R compiler d

47、irectives:以下是一个DCC32.CFG配置文件的例子，定义了关于文件包含、OBJ文件包含、单元文件搜索路径信息，并改变了编译器指令$O和$R的默认值。-IC:DELPHIINC;C:DELPHISRC-OC:DELPHIASM-UC:DELPHIUNITS-$R+-$O-Now, if you type:现在，如果你输入：dcc32 MYSTUFF the compiler performs as if you had typed the following:编译器把它当作你输入如下命令：dcc32 -IC:DELPHIINC;C:DELPHISRC -OC:DELPHIASM -U

48、C:DELPHIUNITS -$R+ -$O- MYSTUFF6 Debug options调试选项The compiler has two sets of command-line options that enable you to generate external debugging information: the map file options and the debug info options.编译器有两个命令行参数可以生成外部调试信息:MAP文件选项和调试信息选项。Map file (-G) optionsMap文件(-G)选项The -G option instructs

49、 the command-line compiler to generate a .map file that shows the layout of the executable file. Unlike the binary format of executable and .dcu files, a .map file is a legible text file that can be output on a printer or loaded into the editor. The -G option must be followed by the letter S, P, or

50、D to indicate the desired level of information in the .map file. A .MAP file is divided into three sections:选项-G指示命令行编译器生成一个.map文件来查看一个可执行文件的布局。不同于可二进制的可执行文件和.dcu文件，.map文件是一个可读的文本文件，可以被打印或是其它文本编辑器编辑。选项-G后必须跟字符S、P或D，去决定你想要在.map文件列出的信息。一个.MAP文件被分成三个节：SegmentPublicsLine Numbers-GS outputs only the Segm

51、ent section, -GP outputs the Segment and Publics section, and -GD outputs all three sections. -GD also generates a .DRC file that contains tables of all string constants declared using the resourcestring keyword.-GS选项只输出Segment Section,-GS选项输出Segment和Publics,-GD输出所有的三个Sections.-GD选项也生成一个扩展名为.DRC的文件包

52、含所有的用resourcestring关键字声明的字符串常量。For modules (program and units) compiled in the $D+,L+ state (the default), the Publics section shows all global variables, procedures, and functions, and the Line Numbers section shows line numbers for all procedures and functions in the module. In the $D+,L- state, o

53、nly symbols defined in a units interface part are listed in the Publics section. For modules compiled in the $D- state, there are no entries in the Line Numbers section.用默认的编译选项$D+,L+编译模块(程序或单元)，Publics Section列举所有的全局变量、过程和函数，Line Numbers Section列举模块中所有的过程和函数的行号。如果用$D+,L-编译选项编译模块，Publics Section中仅列举

54、在单元的interface部分定义的符号。如果用$D-选项编译模块，在Line Numbers Section没有任何入口。Debug info (-V) options调度选项(-V)The -V options (-V, -VN. and -VR), which cause the compiler to generate debug information, can be combined on the command line.选项-V、-VN、-VR会指示编译器生成调试信息，它们能在命令行中组合使用。Generate Turbo Debugger debug info (-V) op

55、tion生成Turbo Debugger使用的调试信息的选项(-V)When you specify the -V option on the command line, the compiler appends Turbo Debugger 5.0-compatible external debug information at the end of the executable file. Turbo Debugger includes both source- and machine-level debugging and powerful breakpoints.当你在命令行中使用-V

56、选项时，编译器会在可执行文件的末尾附加与Turbo Debugger5.0一致的外部调试信息。Turbo Debugger包含代码和硬件级别的强大的断点。 Even though the debug information generated by -V makes the resulting executable file larger, it does not affect the actual code in the executable, and does not require additional memory to run the program.虽然附加调试信息到查执行文件中会

57、使可执行文件增大，但是它并不影响实际可执行文件中的可执行代码，也不需要额外的内存来启动程序。The extent of debug information appended to the executable file depends on the setting of the $D and $L compiler directives in each of the modules (program and units) that make up the application. For modules compiled in the $D+,L+ state, which is the de

58、fault, all constant, variable, type, procedure, and function symbols are known to the debugger. In the $D+,L- state, only symbols defined in a units interface section are known to the debugger. In the $D- state, no line-number records are generated, so the debugger cannot display source lines when y

59、ou debug the application.附加到可执行文件上的调试信息的大小取决于编译这个应用程序要用到的第一个单元中的$D和$L编译器指令。使用编译器默认的选项$D+，$L+来编译模块，所有的常量、变量、类型、过程和函数的符号都会传递给调试器。使用选项$D+，L-编译，仅有在单元interface部分列出的符号才会传递给调试器。使用选项$D-编译，调试信息中没有生成行号信息，所以，调试程序时调试器不能显示源代码中的行。The IDE internal debugger does not use Turbo Debugger debug information. Because gen

60、erating Turbo Debugger debug information almost doubles compile/link time, you should turn off Turbo Debugger debug information generation except when youre debugging the application in Turbo Debugger.IDE内置的调试器不使用Turbo Debugger调试信息。因为生成Turbo Debugger调试信息几乎会成倍的增加编译或链接的时间，你可以关闭生成Turbo Debugger调试信息，除非你
