This is version 4.0.0 of the JX distribution.

Changes from previous versions are described in the *LibVersion.h files in the include file directories.

Changes to the build system

4.2.0

  • Shortened J_COMPILER_DEPEND_FLAGS to J_DEPEND_FLAGS

4.0.0

  • Moved all system logic into ./configure so the system name does not have to be passed to make.
  • Removed source for all embedded libraries. Switched to (now reliably available) pre-compiled libraries, installed by the native package manager. The new ./configure script handles this for known systems.
  • Removed J_COMPILE_DEBUG flag. To build without debugging, create the file 0-RELEASE with content: 1
  • Removed support for shared libraries. RAM is plentiful. This eliminates the following make variables: J_BUILD_SHARED_LIB, J_SHARED_LIB_SUFFIX, J_SHARED_LIB_LINK_OPTION, J_NEED_SEPARATE_O_FILES, J_BEGIN_LINK_STATIC, J_END_LINK_STATIC, RPM_LIB_PATH. Removed J_SYS_LIBS. J_STD_LIBS no longer includes libjcore and libjx, since these should be in LIB_DEPS.
  • Removed obsolete J_MAN_SECTION_VIA_DASH_S.
  • Completely restructured the build system to support Homebrew releases.
  • Renamed _J_OSX to _J_MACOS

2.6.0

  • Removed obsolete build targets and build config.
  • Cleaned up application builds by adding targets in include/make/jx_targets.
  • Changed J_HAS_GD to J_HAS_JPEG. xmp, gif, png are now widely available.
  • Removed crypto, regex, xpm from misc directory.
  • Modified definition of J_STRING_FILES to allow application to override library strings.

2.5.0

  • Added cygwin32 build target.
  • Added Visual C++ workspace and project files for libjcore.
  • Merged libjtree and libjtoolbar into libjcore and libjx.
  • Fixed build system so finished binaries are copied instead of moved. This saves time if build is run multiple times, e.g., during debugging.
  • Collapsed J_HAS_GIF and J_HAS_PNG into single J_HAS_GD build flag.

2.1.0

  • In order to be compatible with the binaries for Code Crusader, Code Medic, etc., LD_LIBRARY_PATH must not include JX-2.1.0/lib. The -R link option is now used instead.
  • ACE_ROOT no longer needs to be defined.

2.0.0

  • All Make.headers should stop defining TOUCHHEADERS. All programs should define touch as a double colon target to run maketouch for the libraries on which they depend.
  • Defined J_STD_LIBS to include libjtoolbar, libjtree, libjx, libjcore, and ${J_SYS_LIBS}. These are the libraries that all programs need.
  • All Make.headers should remove ${ACE_ROOT}, ${J_X11_INCLUDE_DIR}, and ${JX_ROOT}/include/menu_image from SEARCHDIRS because jx_config automatically appends them. As a result of this change, SEARCHDIRS can now be defined with :=.
  • Renamed include/menu_image to include/image and libjx/menu_image to libjx/image.
  • Each file include/make/*_constants must use += to add the library's string data files to J_STRING_FILES so applications can compile all the required strings into one database file.
  • jxlayout now uses a more convenient method of specifying sizing options. Use the convert_gravity script to convert your existing .fd files.
  • jxlayout generates a database of all the strings used by each layout and generates code that uses JStringManager.
  • If a target ends with .so, makemake automatically includes the link option required to produce a shared library. ${J_SHARED_LIB_LINK_OPTION} should no longer be included in LDFLAGS in library Make.header files.
  • Renamed libjparser to libjexpr.

1.5.1

  • All programs must check the value of J_WANT_INSTALL. If it is not zero, they should install themselves into J_INSTALL_ROOT. The reason for the double negative is that this allows the default action to be to install the programs.
  • All programs and libraries must define SEARCHDIRS with = not := so that J_X11_INCLUDE_DIR will work.
  • Fixed ACE build system to never build with threads because some functions (e.g. tmpnam()) don't work the normal way on some systems (e.g. HP-UX 11) when threads are used.

1.5.0

  • Long overdue change in minor version number.
  • Moved jxuninstall target into include/make/default_lib_target so Make.header for libraries no longer needs to define it.
  • Added J_STRIP_DEBUG because Solaris strip uses -x instead of -g.

1.1.23

  • Added J_SHARED_LIB_LINK_OPTION because Solaris ld 3.0 uses -G instead of the defacto -shared. All library Make.header files must switch to using this variable in LDFLAGS.
  • Added J_X11_INCLUDE_DIR because some people are cursed with non-standard X installations. All Make.header files must include ${J_X11_INCLUDE_DIR} (not -I${J_X11_INCLUDE_DIR}) at the end of SEARCHDIRS.
  • Added Make.files_template and Make.header_template in doc directory. These show the minimal requirements for writing a JX program.

1.1.21

  • Works with egcs! Factory methods are used to call the offending code after the constructor has finished. The constructor is protected to force you to call the factory methods instead.
  • If J_BUILD_SHARED_LIB is defined, programs should depend on .so versions of libraries instead of .a versions.
  • Created include/make/default_lib_target to hide J_BUILD_SHARED_LIB and J_NEED_SEPARATE_O_FILES.

1.1.20.1

  • Added J_NEED_SEPARATE_O_FILES. If this and J_BUILD_SHARED_LIB are both defined, libraries should only build the .so version.

1.1.20

  • Fixed configuration so the standard ACE distribution works again.
  • If make is run as root, libraries and binaries are automatically installed in system directories. (3rd party libraries need to add code to their default build target and also add a new target jxuninstall.)

1.1.19

  • For each *_VERSION constant, created new *_LIB_VERSION constant. This defines the library version used in file names.
  • Merged libjxparser into libjparser.
  • Merged libjx3d into libj3d.
