icmbuild - A generic, easy configurable, program maintenance script
The icmbuild script is a generic script that can be used to do program
maintenance using icmake(1).
The script expects two files to be available in the directory where
program maintenance is required, and the icmbuild script should be
available in your path or it should be started as, e.g., ./icmbuild
Icmbuild assumes that your sources exist in and below a directory in
which the files icmconf and CLASSES live. The file CLASSES contains the
names of all subdirectories in which class-specific sources are kept.
The file icmconf in icmake(1)’s distribution offers an example of the
configuration parameters that are used for program maintenance. In this
latter file it is assumed that C++ sources are maintained, but the
icmbuild script is not restricted to do maintenance for C++ programs.
Icmbuild compiles all sources in each of the subdirectories named in
the file CLASSES, and then compiles all sources in the current working
directory (except for the source containing main()).
The compiled sources result in object modules which are then kept in a
library, against which the main-object module is linked. It is also
possible to specify additional libraries against which the program must
Once a library is constructed it is kept up to date by the script.
Changing a source will result in replacing its former module by its new
module in the library.
Normally, icmbuild is installed and used as follows:
o Install icmbuild in your path;
o copy icmconf and CLASSES to your project’s base directory (i.e.,
the directory in which and where below the project’s sources are
o Modify the #defines in the file icmconf to taste;
o List the subdirectories containing sources in the file CLASSES
Note that the order of the classes mentioned in classes is
relevant here. It’s no problem to add new class (subdirectory)
names, but reordering should be prevented. If reordering is
required, recompile the library, as the final object files
contain class order-numbers. These class-order numbers prevent
file-name collisions and thus prevent replacing file x.o from
class A by file x.o from class B;
o Now simply run
from the project’s base directory and let the help-info tell you
what your options are. See the next section for the modes of
Icmbuild may be called with the following operational modes:
clean up remnants of previous activities
provide help and exit (default when called without arguments)
build the library (static and optionally the dynamic library)
build the binary program
o program strip
build the stripped binary program
o install <base> install the software in the locations defined in
the icmconf file, optionally below the directory <base> The
icmconf file may be given a line defining DEFCOM containing the
default operational mode to use when none is specified. E.g.,
#define DEFCOM "program"
constructs the program when the command `icmbuild’ is entered.
DEFCOM may also contain combined options, like
#define DEFCOM "program strip"
Note that DEFCOM is ignored when an explicit operational mode is
provided to the icmbuild script.
The mentioned paths are sugestive only and may be installation

o /usr/share/icmake/CLASSES Example of a icmbuild CLASSES file.
Here is an example of the configuration file icmconf for a concrete
program, using the library libbobcat1 as an additional library:
// Inspect the following #defines. Change them to taste. If you don’t
// need a particular option, change its value into an empty string
// For more information about this file: ’man 7 icmconf’
// The final program and source containing main():
// define the name of the source containing main():
#define MAIN "main.cc"
// define the name of the program to create (don’t use a path here, but
// define the installation path at `BIN_INSTALL’ below) and use
// `icmbuild install’ to install the binary.
#define BINARY "binary"
// Uncomment to relink the binary, even when no sources were
// changed (this is useful if, e.g., a library was rebuilt)
// Uncomment to install the binary in the provided path using
// `icmbuild install’
//#define BIN_INSTALL "/usr/local/bin"
// Defines related to the local libraries to create:
// Uncomment to create a local library rather (when a binary program is
// built it will be linked against the library rather than the individual
// object modules). Change the lib’s name at you own digression (don’t use
// lib or an extension like .a)
//#define LIBRARY "modules"
// Uncomment to construct a shared library
// When creating a shared library:
// Specify the names of any libraries and library paths that are required
// by the shared library. E.g., if a library is found in /usr/lib/special
// use "-L/usr/lib/special -lspecial" if the name of the library is
// The /lib and /usr/lib paths are usually predefined and need not be
#define SHAREDREQ ""
// Uncomment to install the libraries in the provided path using
// `icmbuild install’
//#define LIB_INSTALL "/usr/local/lib"
// #defines used for compilation and linking:
// Uncomment to clear the screen just before starting the compilation
// Uncomment to use the ALL facility and a class dependency setup in the
// CLASSES file. When a directory contains a file ALL (optionally rename
// this filename by providing an alternative name) then all class sources
// and sources of all classes depending on it are also compiled. Class
// dependencies in CLASSES consist of the class name (as the first word on
// a line) optionally followed by additional class names, which are the
// classes directly depending on the line’s first class name.
//#define USE_ALL "a"
// define the compiler to use. Options specified here will always be used
// and cannot be overruled by COMPILER_OPTIONS or COPT settings
#define COMPILER "g++ --std=c++0x -Wall"
// define the compiler options to use.
// To enable GNU extensions in addition to C++0x extensions, add the
// --std=gnu++0x flag
#define COMPILER_OPTIONS "-g -O2"
// define the pattern to locate sources in a directory:
#define SOURCES "*.cc"
// define the options used for linking:
#define LINKER_OPTIONS ""
// By providing the following two #defines the contents of environment
// variables named as specified will overrule, resp. COMPILER_OPTIONS
// and LINKER_OPTIONS. If the #defines are provided and the environment
// variables haven’t been specified then COMPILER_OPTIONS and
// LINKER_OPTIONS will be used as-is
//#define COPT "CXXFLAGS"
//#define LOPT "LDFLAGS"
// define any additional libraries BINARY may need:
#define ADD_LIBRARIES ""
// define any additional paths (other than the standard paths) the
// additional libraries are located in:

// Some advanced #defines, used to create parsers and lexical scanners
// Lexical Scanner section
// Should a lexical scanner be constructed? If so, define the subdirectory
// containing the scanner’s specification file.
#define SCANNER_DIR ""
// What is the program generating the lexical scanner?
