See +the manual for more information on the libraries. -2) The other way creates a project within the source code -directories of wxWindows: In this case I propose to put -all contributed programs in the directory "/user", with a -directory of its own. +2) The other way creates a project within the source code +directories of wxWidgets. For this endeavour, you'll need +GNU autoconf version 2.14 and add an entry to your Makefile.in +to the bottom of the configure.in script and run autoconf +and configure before you can type make. -This directory then should include the following files: - -Makefile (You can copy this one from any application in samples - probably you will not need to edit this one. There is - only one case where you might be interested in changing - this file, but about that see later.) -Makefile.in (This is the base application-Makefile template, from - which the actual Makefile for each system is created. - More about this later) - -put ALL your source code along with all the other stuff you need for -your application in this directory (subdirectories are welcome). - - -** Something about Makefiles ------------------------------- - -On general principle it should only contain ONE line, which is as follows: - - include ../../setup/general/makeapp - -this will include all the necessary definitions for creating the applications - -the only case where you might want to add another line is the following: -this version of configure also supports creation of source archives of the -application for easy distribution and updates to newer version of wxWindows. - For this purpose all files in the application-directory will be put into -a gziped tar-file in the full notation user//* -if you want to include some other files that you want "more visible", like -a README. or a shell script for easy -compilation/installation/distribution, then you have to add a variable - - DISTRIBUTE_ADDITIONAL= - -to the Makefile. -So it would look like this: - - DISTRIBUTE_ADDITIONAL=README.TheApp - include ../../setup/general/makeapp - -As we have already talked about distribution the command to create a -distribution is: - - make distrib - -NOTE: If you are in the base directory of wxWindows it will create -distribution packages for wxWindows as well as for all packages in the -user directory. - So if you want to create only packages for the files in user, -then go to the directory other and type: - - make distrib - -or if you only want one application to be created then -enter the specific directory and type there: -make distrib - -All the distribution files will be put in the directory -distrib at the base of the wxWindows-tree (where also configure -and template.mak can be found). - -** Something about Makefile.in --------------------------------- - -As you have already seen with Makefile, configure makes a lot of use -if the include statement in make to keep the Makefiles as simple as -possible. - -So basically there are only variables to define and then a include command. -Exception to this rule is if you have special rules for some stuff... -These rules should go AFTER the include statement!!! - -so the general header looks like this: - - # wxWindows base directory - WXBASEDIR=@WXBASEDIR@ - # set the OS type for compilation - OS=@OS@ - # compile a library only - RULE=bin - -and the general footer will look like this: - - # include the definitions now - include ../../../template.mak - -the key variable is RULE, which defines what make should create -in this directory. - -here are some examples: - - RULE description - =========================================================================== - bin creates a local binary (for a global binary prefix bin with g) - additional variables needed: - BIN_TARGET this gives the name of your application - BIN_OBJ this gives the object files needed to - link the application - optional variables are: - BIN_SRC this gives the list of c/c++ files for - which dependencies will be checked. - (This can be achieved with: make depend) - BIN_LINK this gives commands for additional - libraries needed to link the application - --------------------------------------------------------------------------- - bin2 creates two local binaries (for global binaries prefix bin2 with g) - in addition to the variables specified above you MUST also - provide the same variables with BIN2_ instead of BIN_ - --------------------------------------------------------------------------- - lib creates a local library (for a global binary prefix bin with g) - additional variables needed: - LIB_TARGET this gives the name of your library - LIB_OBJ this gives the object files needed for - the library to be build. - optional variables are: - LIB_SRC this gives the list of c/c++ files for - which dependencies will be checked. - libbin and libgbin are also possible and will need in addition - the variables from bin - --------------------------------------------------------------------------- - gslib is similar to lib, but it creates a shared library if the system - supports it. - additional variables needed: - LIB_MAJOR major number of the shared library - LIB_MINOR minor number of the shared library - --------------------------------------------------------------------------- - other additional variables: - - ADD_COMPILE define additional includes/defines that - are needed to compile the object files - (if you need to reference some directory - utils - like wxGrid -, then please - reference them with the variables defined - in template.mak - e.g.: $(SRCDIR),$(UTILS), - $(SAMPLES),$(OTHERS)) - - NEEDED_DEFINES lists all the defines that HAVE to be set in - /include/wx/setup.h to compile correctly. - - SRC_DIR lists all directories that are needed to - compile.
