Improve recognition of Wayland and X11 specific build options and
remove duplicates from required dependencies (FLTK_LDLIBS) used in
fltk-config.
This should also fix the GitLab CI build process.
To do: the logic to find the dependencies of Wayland and X11 is
currently suboptimal. This will be improved in a later commit.
This is a big commit and there are too many changes to list them all.
The main changes are:
- rename all CMake build options to 'FLTK_*'
- export library targets with namespace (prefix) 'fltk::'
- standardize shared library target names with suffix '-shared'
- set public build properties on libraries for consumers
- document library names and aliases in README.CMake.txt
- document changes in "Migrating Code from FLTK 1.3 to 1.4"
- partial backwards compatibility for old user projects
Included but not directly related changes:
- fix Windows (Visual Studio) DLL build
- add CMake function fl_debug_target() to show target properties
- don't build test programs if FLTK is a subproject
- internal: reformat CMake code: remove space before '('
Thanks to Matthias and Manolo for their help, testing, and feeback.
... with cmake_minimum_required(VERSION 3.4) or higher. This version
sets CMP0065 to 'NEW' which by default inhibits exporting global
symbols from executable programs.
For details see CMake policy CMP0065 and README.Wayland.txt.
This library is no longer needed in FLTK itself. There is only one
demo program (test/forms.cxx) that uses it if it is built. The demo
program displays a message if fltk_forms is not available.
The default is 'enabled' for backwards compatibility but this may
be changed to 'disabled' in a future version.
1. 'exec_program()' should be replaced with 'execute_process()'. Done.
2. 'cmake -E remove' is broken and deprecated since 3.17, hence we use
'cmake -E rm' (!) for CMake since 3.17 and
'cmake -E remove' only for older CMake versions.
This commit makes the default FLTK build setting use libdecor
as packaged in Linux when the build system contains packages
libdecor-0-dev and libdecor-0-plugin-1-gtk in version ≥ 0.2.0.
Otherwise, FLTK uses the bundled version of libdecor.
This includes situations where package libdecor-0-dev is
present in an earlier version.
This modifies the debug environment so demo programs linked to FLTK
DLL's can be debugged w/o copying FLTK DLL's to the build folders
of the demo programs.
This is work in progress and may be improved in a future commit but
it works as it is now for all demo programs.
- add CMake option 'OPTION_USE_STD'
- add configure option '--enable-use_std'
- move FL/Fl_String.H to src/Fl_String.H
- move FL/Fl_Int_Vector.H to src/Fl_Int_Vector.H
- remove Fl_String from demo program examples/callbacks.cxx
- remove Fl_Int_Vector from public header FL/Fl_Table.H
- some methods of Fl_Table are no longer inline
- add CMake option OPTION_USE_STD to allow std::string in some
selected functions and methods
Experimental, may be removed before release:
- use either Fl_Int_Vector or std::vector in Fl_Table depending
on CMake OPTION_USE_STD or configure --enable-use_std
Move all fl_filename* functions that use Fl_String to fluid
Main changes in fluid:
- add fluid_filename.h and .cxx
- include "fluid_filename.h" rather than <FL/filename.H>
Update fl_input(), fl_password() and test/ask
- add maxchar parameter to fl_input() and fl_password()
- fl_input_str() and fl_password_str() are optional and return
std::string if enabled (FLTK_USE_STD)
... so they are not inherited by consumers of the library.
Remove 'add_definitions(-DFL_LIBRARY)' from src/CMakeLists.txt
This is not necessary, see CMake/fl_add_library.cmake
Don't set obsolete property 'CLEAN_DIRECT_OUTPUT' which was removed
in CMake 2.8.0.
- remove separate libfltk_cairo to avoid cyclic dependencies, but
- keep a dummy libfltk_cairo in 1.4.0 for backwards compatibility
- move cairo/Fl_Cairo.cxx to src/Fl_Cairo.cxx
- add preliminary Cairo support for Visual Studio (MSVC)
Static linking is not affected by this change, but users building
with hand-made Makefiles will have to remove libfltk_cairo starting
with FLTK 1.4.0. The dummy library can be linked for backwards
compatibility but it will be removed later (in 1.4.x or 1.5.0).
The shared FLTK library libfltk.{so|dylib|dll|..} depends on libcairo
if and only if FLTK is built with one of the Cairo options. This has
always been the case for OPTION_CAIROEXT but is now also true if only
OPTION_CAIRO is selected, i.e. FLTK programs linked with a Cairo
enabled shared FLTK library will also be linked with libcairo. The same
is true for configure options --enable-cairo and --enable-cairoext,
respectively.
Preliminary Cairo support for MSVC now detects a Cairo installation
using the CMake variable FLTK_CAIRO_DIR which must be set by the user.
Note that this feature is temporary and may be changed in the future
for a better and more comfortable version.
CMake only: replace wrong variable names with correct ones. Affected
were all image libraries (jpeg, png) and zlib.
These variables had been renamed in an earlier commit when lots of
CMake code had been rewritten.
If available, it is used on Linux regardless of the current desktop because
it offers free XDG portal integration, which means it picks the correct file
chooser on all desktops, and allows for meaningful file selection in sandbox
environments like Flatpak.
This removes the cause of this developer's message
# FIXME: This needs to be redesigned! Forcing GTK_FOUND to 0 (NO) is a bad
# FIXME: idea because there could be unwanted side effects. AlbrechtS
These option combinations work:
-DOPTION_APPLE_X11
-DOPTION_APPLE_X11 -DOPTION_USE_CAIRO
But
-DOPTION_APPLE_X11 -DOPTION_USE_PANGO
is not possible because homebrew doesn't provide the pangoxft package.
This is only one minor step to remove issues of some CMake options
that can cause conflicting include directories ("-I..." switches).
See implementation note in CMake/options.cmake.
This variable has never been used in the code. Configure and CMake
look for a *working* libpng (HAVE_PNG) and set variable HAVE_PNG_H
if the header <png.h> can be included.
The alternative to include <libpng/png.h> is always used in the #else
clause and doesn't need its own config variable. Configure and CMake
log what they find, hence this extra variable is not necessary.
On Windows fluid.exe is a "GUI" program and does not allow console
output which can be a problem in automated builds. In Visual Studio
the fluid GUI program would pop up console windows when generating
.cxx and .h files from .fl files.
The new (additional) fluid-cmd.exe is built as console application
for users that need it and it is used in the FLTK build process on
Windows to convert the .fl files.
I decided not to install the man pages for consistency because we
don't install the executable programs. The instructions are commented
out only so they can be activated easily if this will be changed,
i.e. if we decide to install the test/game programs in the future.
Closes#23
The intended effect (building a Windows "GUI" application), is
correctly achieved using the "WIN32" option of add_executable()
selectively where appropriate rather than setting this platform
specific option for *all* (Windows) executables when using GNU
compilers (MinGW, MSYS2, Cygwin, ...).
According to PR #415 this switch was added in Visual Studio 2015
Update 3. However, version "1900" does not distinguish updates,
hence Visual Studio 2015 up to Update 2 may fail to compile with
this addition. Installing the updates would obviously fix this.
The source files are all encoded by UTF-8 without BOM. This will raise
warnings and errors when compiling by the MSVC with some active code
pages (ACP). The file `test/ask.cxx` contains such characters with UTF-8
encoding. Adding `/utf-8` here is equivalent to specifying
`/source-charset:utf-8 /execution-charset:utf-8`, and all warnings and
errors are removed.
Although CMake uses previously undefined variables like empty strings
it could happen that variables set in the calling context by other
projects initialized some variables with unexpected values.
Example: FLTK_LIBRARIES could have been initialized by previous
execution of 'find_package(FLTK ...)' in a project using FLTK
- set executable permissions on MinGW and more platforms
- add missing link libraries
- improve code formatting (indent)
- mark some variables as advanced
- simplify search for glib-2.0
The Visual Studio generator does often not find GL/glu.h and locale.h
although these headers are in the Visual Studio SDK. The warning has
been changed to "info" and the unnecessary and sometimes confusing
recommendation to rerun CMake has been removed.
fl_debug_pkg(...) can be used to display CMake variables set by
executing pkg_check_modules(). This is for CMake debugging only.
The CMake configuration summary displays configuration options
of Wayland, Pango, Xft, and Cairo configuration.
If a user project is built using a FLTK library generated by CMake
with Cairo support then the CMake variable FLTK_INCLUDE_DIRECTORIES
now includes the required Cairo include directories.
... as discussed in fltk.coredev in thread "RFC: introduce public
config header <FL/fl_config.h>", see:
https://groups.google.com/g/fltkcoredev/c/xLCs1AIXMVo/m/MHZpQggzAQAJ
- Rename abi-version.h to fl_config.h, rename input files,
update dependencies, .gitignore, CMake, configure and Makefiles.
- Include Cairo options in FL/fl_config.h
- Rename FLTK_USE_CAIRO to FLTK_HAVE_CAIROEXT for consistency.
- Include <FL/fl_config.h> in config.h and wherever necessary,
fix include order (move FL/Fl.H to the top) and more.
- Move USE_X11 to fl_config.h and rename to FLTK_USE_X11
- Do not include <config.h> in Cairo demo program which is no
longer required in Cairo programs since FLTK 1.4.0
Use of the kdialog command by class Fl_Naive_File_Chooser can now be turned off
at build-time through CMake OPTION_USE_KDIALOG.
If building via configure + make, set #define USE_KDIALOG to 0 in config.h before make.
CMake/compatibility.cmake: define functions and macros to be used
if a particular CMake functionality requires a higher CMake version
than FLTK's minimum CMake version, see 'cmake_minimum_required(...)'
in the root CMakeLists.txt.
Note: target_link_directories() is available since CMake 3.13
Add CMake test for PTHREAD_MUTEX_RECURSIVE
Add autoconf/configure compile test for PTHREAD_MUTEX_RECURSIVE
Replace "#ifdef PTHREAD_MUTEX_RECURSIVE"
with "#ifdef HAVE_PTHREAD_MUTEX_RECURSIVE"
and define HAVE_PTHREAD_MUTEX_RECURSIVE in config.h
macOS Big Sur 11.3 introduced a new "security feature" such that
app bundles created from existing bundle templates in downloaded
files (tar distibutions, expanded) could no longer be executed
without unsetting the "quarantine" attribute. This commit fixes
this by creating all bundles from scratch.
Known *workaround* for older tarballs and snapshots:
$ xattr -d -r com.apple.quarantine xxx.app
Some of the output variables had not been documented, and the "new"
variable for FLTK include directories is 'FLTK_INCLUDE_DIRS' (plural)
rather than 'FLTK_INCLUDE_DIR'.
FLTK_INCLUDE_DIR is now also set for compatibility with FindFLTK.cmake
supplied by CMake.
- rewrite to use pkg-config with both autoconf + CMake
- remove hardcoded library names
- fix build dependencies and search directories
- remove or replace old and unused variables
- update README files
To be done:
- implement fallback for autoconf/configure if pkg-config is missing
- fix pango build (uses cairo internally)
Use cairo-PostScript to output PostScript when pango is available.
This allows to draw in vectorial form any script.
Before, only the Latin script could be drawn to PostScript in vectorial form.
Now bundle wrapper scripts are created in the particular build folder,
i.e. in subdir 'Debug', 'Release' etc. in multi config builds (Xcode).
To do this, the scripts are now copied whenever the target is built
and not during the configuration phase.
To do: "install" wrapper scripts.
- move target (demo) specific code from macro to CMakeLists.txt
- refactor macOS specific code for a cleaner structure
- improve documentation
Note: CMake ignores platform specific code like creating bundles on
other platforms, hence the entire code could be simplified (less
conditional code)
- raise minimum CMake version from 2.6.3 to 3.2.3 (Jun 01, 2015)
- indent all CMake files according to the CMP (2 col.)
- refactor FLTK version number definitions and usage
- unify CMake and autoconf/configure variable names:
- FL_VERSION -> FLTK_VERSION
- FL_MAJOR_VERSION -> FLTK_VERSION_MAJOR
- etc. for _MINOR_ and _PATCH_, respectively
- note: this does not affect FL_VERSION etc. in source code
- generate "export headers" for all libraries (experimental: OFF)
- port some forgotten goodies from branch-1.3 to master
- merge and improve macro 'create_example' (WIP)
- remove "temporary" options and code for older CMake versions
- include and use 'GenerateExportHeader' (experimental, WIP: OFF)
- note: created header files are not yet used
- build only *one* DLL with Visual Studio (tested, works)
- similar to the bundled IDE projects in 1.3.x
- add some dynamically linked test/demo programs ('*-shared')
if shared libraries are built (WIP)
- split 'macros.cmake': use one file per macro
