POCO C++ Libraries GNU Make Build System
|
|
AAAIntroduction
|
|
|
|
!!!Introduction
|
|
|
|
The POCO C++ Libraries use a built system based on
|
|
[[http://www.gnu.org/software/make/ GNU Make]] on every platform
|
|
capable of running it. This includes Linux, Mac OS X, virtually
|
|
every other Unix platform, as well as Cygwin and MinGW on Windows.
|
|
|
|
Why GNU Make? Well, GNU Make is available virtually everywhere
|
|
and it's usually readily available, such as on Linux and Mac OS X.
|
|
Sure, there are more advanced build systems out there, but the
|
|
philisophy for POCO is download -- compile -- go. Requiring the user
|
|
to download and install another build tool just for getting
|
|
POCO to work is unacceptable.
|
|
|
|
The build system consists of a number of make files, as well as a few
|
|
supporting shell scripts. All core files are located within the <*build*>
|
|
directory in the POCO distribution. For every library and executable,
|
|
there is a small make file describing the kind of project,
|
|
its input files, and the output.
|
|
|
|
The POCO build system automatically determines the dependencies
|
|
between source and header files. This is done when a source file is
|
|
compiled for the first time, or after a source file has been changed.
|
|
This relieves the developer from the tedious task of maintining file
|
|
dependencies manually - one of the biggest drawbacks of GNU Make.
|
|
|
|
|
|
!!Build System Features
|
|
|
|
The POCO build system supports the following features:
|
|
|
|
* building libraries, applications and plugins
|
|
* debug and release builds
|
|
* dynamic and static linking
|
|
* 32-bit and 64-bit builds
|
|
* automatic dependency detection
|
|
* easy to use
|
|
* support for cross-compiling for embedded platforms
|
|
such as Embedded Linux or iOS
|
|
|
|
|
|
!!Build System Overview
|
|
|
|
The core of the build system consists of three different kinds of files --
|
|
platform configuration files, make rules and shell scripts. All are located
|
|
in the <*build*> directory within the POCO C++ Libraries root directory.
|
|
|
|

|
|

|

|
|

|
|

|
|
shlibln
|
|
...
|
|
----
|
|
|
|
|
|
!Configuration Files
|
|
|
|
Configuration files contain all the knowledge how the toolchain (compiler and linker)
|
|
must be invoked for a given platform. Configuration files for the most common
|
|
Unix platforms and their toolchains, as well as for Cygwin and MinGW are already
|
|
part of POCO.
|
|
Support for an additional platform (or a variation of a platform) can be added
|
|
by creating a new (or copying and modifying) an existing build configuration file.
|
|
|
|
Configuration files are located in the <*build/config*> directory.
|
|
|
|
|
|
!Rule Files
|
|
|
|
Rule files contain platform independent make rules for compiling and
|
|
linking executables or (static and shared) libraries from source files,
|
|
using the tools defined in a configuration file. Rule files are located
|
|
in the <*build/rules*> directory.
|
|
|
|
|
|
!Script Files
|
|
|
|
Script files are called by the build system's make files to do things that
|
|
cannot be expressed in make files. For example, there are scripts for
|
|
invoking a particular C++ compiler in such a way that it produces a list of
|
|
dependencies for later inclusion by the build system. Script files are
|
|
located in the <*build/script*> directory.
|
|
|
|
|
|
|
|
!!Filesystem Layout
|
|
|
|
!Sources
|
|
|
|
The build system expects a project's files (header files, source files, Makefiles)
|
|
to be in a certain directory layout.
|
|
First, all project directories must be located in or under the same directory where the
|
|
<*build*> directory is located, or in a directory below.
|
|
All header files must be in the <*include*> directory (or a subdirectory of it).
|
|
All source files must be in the <*src*> directory.
|
|
Finally, there must be a Makefile (named <*Makefile*>) located in the project directory.
|
|
|
|
Below is a sample for a POCO source directory hierarchy:
|
|
|
|
poco/
|
|
build/
|
|
Foundation/
|
|
Net/
|
|
Util/
|
|
XML/
|
|
...
|
|
|
|
MyLib/
|
|
include/
|
|
MyLib.h
|
|
MyClass.h
|
|
|
|
src/
|
|
MyClass.cpp
|
|
|
|
Makefile
|
|
----
|
|
|
|
|
|
!Build Products
|
|
|
|
The POCO build system puts final build products (executables and libraries)
|
|
and intermediate products (object files, dependency files) into certain directories.
|
|
Unless specified otherwise (by setting the environment variable
|
|
POCO_BUILD accordingly -- see below), these directories are located within
|
|
the source directory tree. All libraries are put into a
|
|
directory with the path <*lib/<OSNAME>/<OSARCH>*>, within the POCO base directory.
|
|
Executables are put into a directory with the path <*bin/<OSNAME>/<OSARCH>*>,
|
|
within the project directory. Object files are put into a directory with the
|
|
path <*obj/<OSNAME>/<OSARCH>*>, within the project directory.
|
|
Dependency files are put into <*.dep/<OSNAME>/<OSARCH>*>,
|
|
also within the project directory.
|
|
|
|
Unless specified otherwise (by setting the Makefile variables
|
|
<[$(POCO_TARGET_OSNAME)]> and <[$(POCO_TARGET_OSARCH)]>, <*<OSNAME>*> is the
|
|
name of the host's operating system, as obtained by a call to
|
|
<*uname*> (or something equivalent), and <*<OSARCH>*> is the name of the
|
|
host's hardware architecture, as obtained by a call to <*uname -m*>
|
|
(or something equivalent).
|
|
|
|
Taking into account the build products, a typical project hierarchy looks like this:
|
|
|
|
|
|
poco/
|
|
build/
|
|

|
|

Makefile
|
|
----
|
|
|
|
|
|
!!Project Makefiles
|
|
|
|
Depending on the kind of project, a project Makefile comes in one of three variants.
|
|
|
|
|
|
!Library Makefiles
|
|
|
|
The Makefile for a library always looks like this:
|
|
|
|
#
|
|
# Makefile for a library
|
|
#
|
|
|
|
include $(POCO_BASE)/build/rules/global
|
|
|
|
objects = MyClass ...
|
|
|
|
target = MyLib
|
|
target_version = 1
|
|
target_libs = PocoFoundation ...
|
|
|
|
include $(POCO_BASE)/build/rules/lib
|
|
----
|
|
|
|
|
|
Every Makefile always has to include <*$(POCO_BASE)/build/rules/global*> first.
|
|
In the <*objects*> section, the source files (located in the <*src*> directory)
|
|
must be specified. The file extension must not be included; the build system
|
|
will find files ending in .cpp (C++ sources) and .c (C sources).
|
|
<*target*> specifies the name of the library, <*target_version*> specifies the
|
|
version number for the shared library. <*target_libs*> specifies the
|
|
libraries required for linking the library.
|
|
|
|
Last in the Makefile is the inclusion of <*$(POCO_BASE)/build/rules/lib*>,
|
|
which includes the rules for building a shared or static library.
|
|
|
|
|
|
!Executable Makefiles
|
|
|
|
Makefiles for executables look similar to the ones for libraries.
|
|
|
|
|
|
#
|
|
# Makefile for a library
|
|
#
|
|
|
|
include $(POCO_BASE)/build/rules/global
|
|
|
|
objects = MyClass ...
|
|
|
|
target = MyLib
|
|
target_libs = PocoFoundation ...
|
|
|
|
include $(POCO_BASE)/build/rules/exec
|
|
----
|
|
|
|
|
|
|
|
The only differences are the missing <*target_version*> entry, and the
|
|
<*$(POCO_BASE)/build/rules/exec*> file, which is included instead of
|
|
<*$(POCO_BASE)/build/rules/lib*> at the end of the Makefile.
|
|
|
|
|
|
|
|
!Plugin Makefiles
|
|
|
|
|
|
|
|
Makefiles for plugins - shared libraries that are loadable dynamically at runtime - again look almost the same as Makefiles for ordinary libraries or executables.
|
|
|
|
#
|
|
# Makefile for a library
|
|
#
|
|
|
|
include $(POCO_BASE)/build/rules/global
|
|
|
|
objects = MyClass ...
|
|
|
|
target = MyPlugin
|
|
target_libs = PocoFoundation ...
|
|
|
|
include $(POCO_BASE)/build/rules/dylib
|
|
----
|
|
|
|
|
|
The difference is the file that is included at the end of the Makefile:
|
|
<*$(POCO_BASE)/build/rules/dylib*>.
|
|
|
|
|
|
!!!Build System Reference
|
|
|
|
|
|
!!Target Variables
|
|
|
|
!target
|
|
|
|
The <*target*> variable specifies the name of the resulting library or executable,
|
|
excluding the suffix.
|
|
|
|
|
|
!target_version
|
|
|
|
The <*target_version*> variable specifies the shared library version of the resulting
|
|
shared library.
|
|
|
|
|
|
!target_libs
|
|
|
|
The <*target_libs*> variable specifies all libraries that must be linked to the
|
|
target. These libraries must have been built with this build system and they
|
|
must follow the build system conventions, specifically, the names for debug
|
|
and release builds.
|
|
|
|
|
|
!target_extlibs
|
|
|
|
The <*target_extlibs*> variables specifies additional libraries that must be
|
|
linked to the target. No assumptions are made regarding debug or release builds.
|
|
The names given here are simply passed to the linker by prepending the <[-l]> flag.
|
|
|
|
|
|
!target_includes
|
|
|
|
The <*target_includes*> variable specifies a list of directories used for searching
|
|
header files.
|
|
|
|
|
|
!!Postbuild Command
|
|
|
|
A Makefile can contain a so-called postbuild command -- a shell command
|
|
that will be executed when the target has been built successfully.
|
|
To specify a postbuild command, define the variable <*postbuild*>
|
|
in your Makefile, e.g.
|
|
|
|
#
|
|
# Makefile for a library
|
|
#
|
|
|
|
include $(POCO_BASE)/build/rules/global
|
|
|
|
objects = MyClass ...
|
|
|
|
target = MyLib
|
|
target_libs = PocoFoundation ...
|
|
|
|
postbuild = echo "The build is done."
|
|
|
|
include $(POCO_BASE)/build/rules/exec
|
|
----
|
|
|
|
|
|
!!Make Targets
|
|
|
|
Independently of which kind of product (library, executable, plugin) is
|
|
being built, there are always five make targets available:
|
|
Note that these targets are only available in project-level Makefiles, not
|
|
the global Makefile.
|
|
|
|
!clean
|
|
|
|
The <*clean*> target will remove all executable and intermediate object files,
|
|
forcing a full rebuild with the next make.
|
|
|
|
|
|
!all
|
|
|
|
<*all*> is the default target, used if no other target is specified.
|
|
Depending on the current configuration, it will either build a statically linked or
|
|
dynamically linked library/executable, or both.
|
|
|
|
|
|
!static_debug
|
|
|
|
The <*static_debug*> target will build a statically linked debug version of
|
|
the library or executable. Statically linked executables will be linked
|
|
in the <*static*> subdirectory within the <*bin/<OSNAME>/<OSARCH>*> directory.
|
|
Debug libraries and executables have a 'd' appended to their basename
|
|
(e.g., MyLibd.so).
|
|
|
|
|
|
!static_release
|
|
|
|
The <*static_release*> target will build a statically linked release
|
|
version of the library or executable.
|
|
|
|
|
|
!shared_debug
|
|
|
|
The <*shared_debug*> target will build a dynamically linked debug version
|
|
of the library or executable. The library or executable will
|
|
have the suffix <*d*> appended to its name (e.g., if target is MyExec,
|
|
the actual name of the executable will be MyExecd).
|
|
|
|
|
|
!shared_release
|
|
|
|
The <*shared_release*> target will build a dynamically linked release
|
|
version of the library or executable.
|
|
|
|
|
|
!!Environment Variables
|
|
|
|
The POCO build system requires or uses certain environment variables to work properly.
|
|
|
|
!POCO_BASE
|
|
|
|
<*POCO_BASE*> is required and specifies the directory where the POCO
|
|
source tree is located.
|
|
|
|
|
|
!POCO_BUILD
|
|
|
|
<*POCO_BUILD*> specifies the directory where the build system puts all
|
|
intermediate build files (object files, dependency files) and build
|
|
products (libraries and executables). Normally, these files are located
|
|
within the POCO source tree. Setting POCO_BUILD allows to keep the POCO
|
|
source tree clean and free of binaries.
|
|
|
|
|
|
!POCO_CONFIG
|
|
|
|
<*POCO_CONFIG*> specifies the build configuration file (located in build/config)
|
|
to use. Defaults to the output of <*uname*> if not specified.
|
|
|
|
|
|
!POCO_TARGET_OSNAME and POCO_TARGET_OSARCH
|
|
|
|
<*POCO_TARGET_OSNAME*> and >*POCO_TARGET_OSARCH*> are used in
|
|
cross builds, to specify the operating system name and hardware
|
|
architecture of the target. These names is used to find the directory
|
|
where intermediate object files and final build products are put.
|
|
Intermediate files are always put into <*obj/<OSNAME>/<OSARCH>*>
|
|
and final build products are put into <*lib/<OSNAME>/<OSARCH>*>, or
|
|
<*bin/<OSNAME>/<OSARCH>*>, respectively.
|
|
If <*POCO_TARGET_OSNAME*> is specified, its value becomes the
|
|
value for <*<OSNAME>*>. If <*POCO_TARGET_OSARCH*> is specified, its value
|
|
likewise becomes the value for <*<OSARCH>*>
|
|
|
|
The default value for <*<OSNAME>*> is the output of <*uname*> or a
|
|
similar command.
|
|
The default value for <*<OSARCH>*> is the output of <*uname -m*> or a
|
|
similar command.
|
|
|
|
|
|
!OSARCH_64BITS
|
|
|
|
If defined to 1, will force a 64 bit build on platforms that support 64 bit builds.
|
|
|
|
|
|
!PROJECT_BASE
|
|
|
|
|
|
Setting this environment variable allows you to use the build system to
|
|
build POCO-based libraries and executables outside the POCO_BASE directory
|
|
hierarchy. Given a directory <*/projects*> containing a project directory
|
|
<*MyProject*> (that is, <*/projects/MyProject*>), <*PROJECT_BASE*>
|
|
must be set to <*/projects*>. Assuming <*/projects/MyProject/Makefile*>
|
|
is available, you can change to the <*/projects/MyProject*> directory and
|
|
invoke <*gmake*> to build your project. <*POCO_BASE*> must still be set
|
|
and point to the POCO source tree, as usual.
|
|
|
|
|
|
!!Special Files
|
|
|
|
!components
|
|
|
|
The build system requires a file named <*components*> being located in
|
|
<*$(POCO_BASE)*>. This file contains a list of project names, one per line.
|
|
The contents of this file are used by the build system to automatically
|
|
build include search paths. For example, if <*components*> has the following content:
|
|
|
|
Foundation
|
|
XML
|
|
Util
|
|
Net
|
|
----
|
|
|
|
the following include search path options will be used for compiling:
|
|
|
|
-I$(POCO_BASE)/Foundation/include -I$(POCO_BASE)/XML/include -I$(POCO_BASE)/Util/include -I$(POCO_BASE)/Net/include
|
|
----
|
|
|
|
|
|
If a new library is being added to POCO, a corresponding entry should be made in the <*components*> file, so that the compiler can find its header files.
|
|
|
|
|
|
!libversion
|
|
|
|
The content of the file <*libversion*>, located in <*$(POCO_BASE)*>,
|
|
will be stored in the variable <*$(LIBVERSION)*>. This variable can be used
|
|
in a Makefile as the value for the <*target_version*> variable.
|
|
|
|
|
|
!Configuring the Build Process
|
|
|
|
The build process is configured by build configuration files,
|
|
located in the <*build/config*> directory.
|
|
Unless specified otherwise, by setting the <*POCO_CONFIG*>
|
|
environment variable accordingly, the build system selects the
|
|
build configuration file with the same name as the host's
|
|
operating system (output of <*uname*>). If you need support for a
|
|
new operating system, or just need to customize an existing configuration,
|
|
you'll usually create a new build configuration file (by copying an existing one).
|
|
|
|
A typical build configuration file looks like this:

For cross builds, <*TOOL*> specifies the prefix for the toolchain executables, e.g.
|
|
|
|
TOOL = arm-unknown-linux-gnu
|
|
----
|
|
|
|
<*TOOL*> can later be used in the tool section, as in:
|
|
|
|
CC = $(TOOL)-gcc
|
|
CXX = $(TOOL)-g++
|
|
...
|
|
----
|
|
|
|
|
|
!POCO_TARGET_OSNAME and POCO_TARGET_OSARCH
|
|
|
|
The general settings section is also the right place to define
|
|
<*POCO_TARGET_OSNAME*> and <*POCO_TARGET_OSARCH*> for cross builds.
