libdecor/build/Makefile: unused anyway (previously used building demos)
src/CMakeLists.txt: broke some user builds, see fltk.general, thread
"-no-pie in FLTK Libraries build." (Mar 17, 2024).
Todo: check usage of "-fPIC" (libdecor builds)
Option: ./configure --disable-test build test programs (default=yes)
Thanks for the patch(es) to @michaelbaeuerle.
I added `make test` to be able to build the test programs from the
FLTK root directory if FLTK was configured with --disable-test.
Fix usage of vsscanf in Fl_Unix_System_Driver::clocale_vsscanf().
Final commit of all patches provided by the OP of issue #937 - if
everything works now.
Some of these accessor methods should be private so they can't be used
by user code but - due to compiler issues - they must be public for
HP-UX 11.11 (for details see GitHub Issue #937).
With modern CMake libcairo doesn't need to linked explicitly in the
test/cairo_test.cxx demo program. Either '-lcairo' is implied by
linking with fltk::fltk or it is not used at all.
This fixes a linker warning on macOS:
"ld: warning: ignoring duplicate libraries ..."
Fl_X11_Screen_Driver::set_spot() did not free the list of missing
fonts returned by XCreateFontSet().
This commit also initializes some variables and reformats code, but
the only notable change is to call XFreeStringList(missing_list) if
missing_list is not NULL.
Works now much better with old C99 and C++98 standard compilers.
Fixed: C++ comments in C files and headers included by C files.
There are still some warnings with C90 though but these would be
hard to fix and left as-is for now.
test/fractals.cxx: some arrays were too small by 1, or the compiler
warned at least (false positive?). Anyway, it's fixed now.
- it's no longer necessary to take care of the change in the layout of "struct libdecor"
between versions ≤ 0.2.2 and > 0.2.2 of libdecor
- version > 0.2.2 contains MR131, that is, it defines LIBDECOR_WINDOW_STATE_RESIZING
so the hack to emulate it is no longer necessary
- CMake option FLTK_USE_SYSTEM_LIBDECOR now requires libdecor version > 0.2.2
to be activated, otherwise the bundled libdecor is used
- what will be the libdecor version after 0.2.2 (0.2.3? 0.3.0?) is not known as of today
