Csc Task

Description

Compiles C# source into executables or modules. csc.exe on Windows or mcs on any other platform must be on the execute path, unless another executable or the full path to that executable is specified in the executable parameter

All parameters are optional: <csc/> should suffice to produce a debug build of all *.cs files. However, naming an destFile stops the csc compiler from choosing an output name from random, and allows the dependency checker to determine if the file is out of date.

The task is a directory based task, so attributes like includes="*.cs" and excludes="broken.cs" can be used to control the files pulled in. By default, all *.cs files from the project folder down are included in the command. When this happens the output file -if not specified- is taken as the first file in the list, which may be somewhat hard to control. Specifying the output file with destFile seems prudent.

For more complex source trees, nested src elements can be supplied. When such an element is present, the implicit fileset is ignored. This makes sense, when you think about it :)

For historical reasons the pattern **/*.cs is preset as includes list and you can not override it with an explicit includes attribute. Use nested <src> elements instead of the basedir attribute if you need more control.

References to external files can be made through the references attribute, or via nested <reference> filesets. With the latter, the timestamps of the references are also used in the dependency checking algorithm.

Parameters

Attribute Description Type Required
additionalmodules Semicolon separated list of modules to refer to. String Optional
debug set the debug flag on or off. boolean
definitions Semicolon separated list of defined constants. String
destdir Set the destination directory of files to be compiled. File
destfile Set the name of exe/library to create. File
docfile file for generated XML documentation File
executable set the name of the program, overriding the defaults. Can be used to set the full path to a program, or to switch to an alternate implementation of the command, such as the Mono or Rotor versions -provided they use the same command line arguments as the .NET framework edition String
extraoptions Any extra options which are not explicitly supported by this task. String
failonerror If true, fail on compilation errors. boolean
filealign Set the file alignment. Valid values are 0,512, 1024, 2048, 4096, 8192, and 16384, 0 means 'leave to the compiler' int
fullpaths If true, print the full path of files on errors. boolean
includedefaultreferences If true, automatically includes the common assemblies in dotnet, and tells the compiler to link in mscore.dll. set the automatic reference inclusion flag on or off this flag controls the /nostdlib option in CSC boolean
incremental set the incremental compilation flag on or off. If set to true this will result in adding /incremental+ to the csc command line which is not supported anymore in .NET 3.5. boolean
mainclass Sets the name of main class for executables. String
noconfig A flag that tells the compiler not to read in the compiler settings files 'csc.rsp' in its bin directory and then the local directory boolean
optimize If true, enables optimization flag. boolean
outputfile The output file. This is identical to the destFile attribute. File
referencefiles Path of references to include. Wildcards should work. Path
references Semicolon separated list of DLLs to refer to. String
srcdir Set the source directory of the files to be compiled. File
targettype set the target type to one of exe|library|module|winexe "exe", "library", "module", "winexe"
unsafe If true, enables the unsafe keyword. boolean
utf8output If true, require all compiler output to be in UTF8 format. boolean
warnlevel Level of warning currently between 1 and 4 with 4 being the strictest. int
win32icon Set the filename of icon to include. File
win32res Sets the filename of a win32 resource (.RES) file to include. This is not a .NET resource, but what Windows is used to. File
useresponsefile Sets whether a response file instead of a command line only invocation should be used. Defaults to false but Ant will still use a response file if more than 64 command line arguments would be used. boolean

Parameters as nested elements

define (org.apache.ant.dotnet.compile.DotnetDefine)

add a define to the list of definitions

reference (org.apache.tools.ant.types.FileSet)

add a new reference fileset to the compilation

resource (org.apache.ant.dotnet.compile.DotnetResource)

link or embed a resource

src (org.apache.tools.ant.types.FileSet)

add a new source directory to the compile
