// script generated by the C++ icmake script version 2.16a
6
Configurable defines for the build script:
8
CLASSES: string of directory-names under which sources of classes
9
are found. E.g., CLASSES = "class1 class2"
11
All class-names must be stored in one string.
12
If classes are removed from the CLASSES definition or if the
13
names in the CLASSES definition are reordered, the compilation
14
should start again from scratch.
22
// ADD ADDITIONAL DIRECTORIES CONTAINING SOURCES OF CLASSES HERE
23
// Use the construction `CLASSES += "classname1 classname2";' etc.
29
Default values for the following variables
30
are found in $IM/default/defines.im
32
BUILD_LIBRARY: define this if you want to create a library for the object
33
modules. Undefined by default: so NO LIBRARY IS
34
BUILT. This links ALL object files to a program, which is
35
a faster process than linking to a library. But it can
36
bloat the executable: all o-modules, rather than those
37
that are really used, become part of the program's code.
39
BUILD_PROGRAM: define if a program is to be built. If not defined,
40
library maintenance is assumed (default: defined).
42
COMPILER: The compiler to use.
43
COPT: C-options used by COMPILER
45
ECHO_REQUEST: ON (default) if command echoing is wanted, otherwise: set
47
GDB: define if gdb-symbolic debug information is wanted
48
(not defined by default)
50
LIBS: Extra libraries used for linking
51
LIBPATH: Extra library-searchpaths used for linking
53
QT: Define this (default: to "qt") if the unthreaded QT
54
library is used. Define as "qt-mt" if the threaded QT
56
If set, header files are grepped for the occurrence of
57
the string '^[[:space:]]*Q_OBJECT[[:space:]]*$'. If found,
58
moc -o moc<CLASSNAME>.cc <CLASSNAME>.h is called if
59
the moc-file doesn't exist or is older than the .h file.
60
Also, if defined the proper QT library is linked, assuming
61
that the library is found in the ld-search path
62
(E.g., see the environment variable $LIBRARY_PATH).
64
Note that namespaces are NOT part of the build-script: they are only
65
listed below for convenience. When they must be altered, the defaults must
66
be changed in $IM/default/defines.im
68
RELINK: Defined by default, causing a program to be
69
relinked every time the script is called. Do not
70
define it if relinking should only occur if a
71
source is compiled. No effect for library maintenance.
