On Windows you need +to let DEFINES contain "QT_DLL" if you are building a Qt program +which should link with the Qt DLL. + + +<h4><a name="DEF_FILE"></a>DEF_FILE</h4> +Win32/app.t only: Specifies a .def file. + + +<h4><a name="DESTDIR"></a>DESTDIR</h4> +Specifies where to put the target file. +Example:<pre> + DESTDIR = ../../lib +</pre> +You must create this directory before running make. + + +<h4><a name="DISTFILES"></a>DISTFILES</h4> +Adds other files to the distribution archive ("dist target"). +The source files and project file are always included in the +distribution archive. +Example:<pre> + DISTFILES = CHANGES README +</pre> + + +<h4><a name="HEADERS"></a>HEADERS</h4> +Defines the header files of the project. + + +<h4><a name="INCPATH"></a>INCPATH</h4> +This variable is generated from <code>INCLUDEPATH</code>. The ';' or ':' +separators have been replaced by ' ' (single space). This makes it +easier to split. qtapp.t and other templates expand +<code>INCPATH</code> to set -I options for the C++ compiler. + + +<h4><a name="INCLUDEPATH"></a>INCLUDEPATH</h4> +This variable specifies the #include directories. It can be set in the +project file, or by the <a href="#AddIncludePath">AddIncludePath()</a> +function.<p> +Example:<pre> + INCLUDEPATH = c:\msdev\include d:\stl\include +</pre> +Use ';' or space as the directory separator. + + +<h4><a name="LIBS"></a>LIBS</h4> +Defines additional libraries to be linked in when creating an application +or a shared library.

You can either specify a +.rc file or one or more .res files. + + +<h4><a name="SOURCES"></a>SOURCES</h4> +Defines the source files of the project. + + +<h4><a name="SRCMOC"></a>SRCMOC</h4> +This variable is generated by the <a href="#StdInit">StdInit()</a> function if +<code>CONFIG</code> contains "qt". <code>SRCMOC</code> contains the name of +all intermediate moc files.<p> +Example:<pre> + HEADERS = demo.h + SOURCES = demo.cpp main.cpp +</pre> +If <tt>demo.h</tt> and <tt>main.cpp</tt> define classes that use signals +and slots (i.e. the <code>Q_OBJECT</code> "keyword" is found in these two +files), <code>SRCMOC</code> becomes:<pre> + SRCMOC = moc_demo.cpp main.moc +</pre> +See also: <a href="#OBJMOC">OBJMOC</a>. + + +<h4><a name="TARGET"></a>TARGET</h4> +Sets the makefile target, i.e. what program to build. + + +<h4><a name="TEMPLATE"></a>TEMPLATE</h4> +Sets the default template. This can be overridden by the tmake -t +<a href="tmake.html#usage">option</a>. + + +<h4><a name="TMAKE_CC"></a>TMAKE_CC</h4> +Contains the name of the compiler. + + +<h4><a name="TMAKE_CFLAGS"></a>TMAKE_CFLAGS</h4> +Contains the default compiler flags. + + +<h4><a name="TMAKE_FILEVARS"></a>TMAKE_FILEVARS</h4> +Tells tmake which variables contain file names. This is because tmake +on Windows replace the directory separator / with \. + + +<hr> +<h2>Function Reference</h2> +This section contains a brief description of some important +tmake functions used by the templates. + + +<h3><a name="AddIncludePath"></a>AddIncludePath(path)</h3> +Adds <em>path</em> to the include path variable, +<a href="#INCLUDEPATH">INCLUDEPATH</a>. The include path is used +for two purposes:<ol> +<li>Searching files when generating include dependencies. +<li>Setting -I options for the C/C++ compiler. +</ol> +<p> +Example:<pre> + #$ AddIncludePath('$QTDIR/include;/local/include'); +</pre> + + +<h3>BuildMocObj(objects,sources)</h3> +Creates build rules for moc source files. Generates +include dependencies.<p> +Example:<pre> + #$ BuildMocObj($project{"OBJMOC"},$project{"SRCMOC"}); +</pre>Output:<pre> + moc_hello.o: moc_hello.cpp \ + hello.h \ + ... +</pre> + +<h3>BuildMocSrc(files)</h3> +Creates moc source files from C++ files containing classes that +define signals and slots. For a header file <tt>x.h</tt>, the +generated moc file is called <tt>moc_x.h</tt>. For a source file +<tt>y.cpp</tt>, the generates moc file is called <tt>y.moc</tt> and +should be #include'd by <tt>y.cpp</tt>.<p> +Example:<pre> + #$ BuildMocSrc($project{"HEADERS"}); + #$ BuildMocSrc($project{"SOURCES"}); +</pre>Output:<pre> + moc_hello.cpp: hello.h + $(MOC) hello.h -o moc_hello.cpp +</pre> + + +<h3>BuildObj(objects,sources)</h3> +Creates build rules for source files. Generates +include dependencies.<p> +Example:<pre> + #$ BuildObj($project{"OBJECTS"},$project{"SOURCES"}); +</pre>Output:<pre> + hello.o: hello.cpp \ + hello.h \ + ... + + main.o: main.cpp \ + hello.h \ + ... +</pre> + + +<h3>Config(string)</h3> +Returns true if the <code>CONFIG</code> variable contains the given string. +<p>Example:<pre> + #$ if ( Config("release") { } +</pre> + + +<h3>DisableOutput()</h3> +Call this function to force tmake to generate no output until +EnableOutput() is called. +<p>Example:<pre> + #$ Config("debug") && DisableOutput(); + Anything here is skipped if CONFIG contains "debug". + #$ Config("debug") && EnableOutput(); +</pre> + + +<h3>EnableOutput()</h3> +Enables tmake output after DisableOutput() was called. + + +<h3>Expand(var)</h3> +Expands a project variable. Equivalent to <code>$text = $project{$var}</code>. +<p>Example:<pre> + VERSION = #$ Expand("VERSION"); +</pre>Output:<pre> + VERSION = 1.1 +</pre> + +<h3>ExpandGlue(var,prepend,glue,append)</h3> +Expands a $project{} variable, splits on whitespace +and joins with $glue. $prepend is put at the start +of the string and $append is put at the end of the +string. The resulting string ($text) becomes "" if +the project variable is empty or not defined.<p> +Example:<pre> + clear: + #$ ExpandGlue("OBJECTS","-del","\n\t-del ",""); +</pre>Output (Windows NT):<pre> + clear: + -del hello.obj + -del main.obj +</pre> + + +<h3>ExpandList(var)</h3> +This function is suitable for expanding lists of files. +Equivalent with <code>ExpandGlue($var,""," \\\n\t\t","")</code>.<p> +Example:<pre> + OBJECTS = #$ ExpandList("OBJECTS"); +</pre>Output:<pre> + OBJECTS = hello.o \ + main.o +</pre> + + +<h3>ExpandPath(var,prepend,glue,append)</h3> +Similar to ExpandGlue, except that it splits the items on a semicolon +instead of space (if the variable contains at least one semicolon). + + +<h3>IncludeTemplate(file)</h3> +Includes a template file. The ".t" extension is optional.<p> +Example:<pre> + #$ IncludeTemplate("mytemplate"); +</pre> + + +<h3>Now()</h3> +Sets $text to the current date and time.<p> +Example:<pre> + # Generated at #$ Now() +</pre>Output:<pre> + # Generated at 12:58, 1996/11/19 +</pre> + + +<h3>Project(strings)</h3> +This is a powerful function for setting and reading project +variables. Returns the resulting project variables (joined with space +between). +<p>Examples:<pre> +# Get a project variable: + $s = Project("TEMPLATE"); -> $s = "TEMPLATE" + +# Set a project variable: + Project("TEMPLATE = lib"); -> TEMPLATE = lib + Project("CONFIG =";) -> CONFIG empty + +# Append to a project variable: + Project("CONFIG = qt"); -> CONFIG = qt + Project("CONFIG += debug"); -> CONFIG = qt debug + +# Append to a project variable if it does not contain the value already: + Project("CONFIG = qt release"); -> CONFIG = qt release + Project("CONFIG *= qt"); -> CONFIG = qt release + Project("CONFIG *= opengl"); -> CONFIG = qt release opengl + +# Subtract from a project variable: + Project("THINGS = abc xyz"); -> THINGS = abc xyz + Project("THINGS -= abc"); -> THINGS = xyz + +# Search/replace on a project variable: + Project("CONFIG = tq opengl"); -> CONFIG = tq opengl + Project("CONFIG /= s/tq/qt/"); -> CONFIG = qt opengl + +# The operations can be performed on several project variables at a time. + + Project("TEMPLATE = app", "CONFIG *= opengl", "THINGS += klm"); +</pre> + + +<h3><a name="ScanProject"></a>ScanProject(file)</h3> +Scans a project file and stores the project variables and values in the +global associative <code>%project</code> array. + + +<h3><a name="StdInit"></a>StdInit()</h3> +Standard initialization of tmake. StdInit() should be +called from one of the first lines in the template.<p> + +This function creates some new project variables:<ul> +<li><code><a href="#OBJECTS">OBJECTS</a></code> + - Object files corresponding to + <code><a href="#SOURCES">SOURCES</a></code>. +<li><code><a href="#SRCMOC">SRCMOC</a></code> - moc source files. +<li><code><a href="#OBJMOC">OBJMOC</a></code> - moc object files. +</ul> + +The moc-related variables are created only if <code>CONFIG</code> contains "qt" + + +<h3>Substitute(string)</h3> +This function takes a string and substitutes any occurrence of $$var +with the actual content of the variable. Returns the substituted string. +Also sets $text. +<p> +Important: Use single quotes around the string, otherwise perl will expand +any $vars it finds. +<p>Example:<pre> + Substitute('Project name: $$PROJECT, uses template $$TEMPLATE'); +</pre> |
