The test system is Slackware 14.2, which uses Qt 4.8.7.
* WANT_WIN_QT4 is defined, and has the expected meaning. Qt 5 is still
the default.
* The QT_NO_SOUND macro now excludes all headers and declarations
relating to sound; the multimedia package is not needed to build
(on any Qt 4, 5 or 6).
* A new function, nh_qsprintf, replaces QString::asprintf, for Qt
older than 5.5. These versions do not have QString::asprintf.
* DYNAMIC_STATUSLINES is disabled for Qt older than 5.9. These versions
do not have QSplitter::replaceWidget.
Shuffling gem appearances can cause mappings from object to
appearance that are not one-to-one. Copy any multiple mappings and
free any mappings that are left unused.
We don't know at compile time whether the X server even supports
Unicode. So take the configured map font, change the registry to
ISO10646 and try the resulting font string. Keep the configured
font if that doesn't work.
Older X servers don't understand "Fuchsia," and NetHack throws
impossibles as a result. The current Xorg defines "magenta" as the
same color as "Fuchsia," namely #FF00FF, and older X servers
understand "magenta."
The resulting X11 NetHack is known to work with XFree86 4.2.0.
The minimum version remains undetermined.
GCCs older than 3.1 understand __attribute__(printf(...)), but only
with functions; it doesn't work with function pointers. This change
uses PRINTF_F_PTR to remove the attribute from two function pointers.
This change establishes GCC 3.0 as the minimum version to build
NetHack. Older versions have trouble with the variadic macros and
variable declarations in mid-block.
* When saving: curses_exit_nhwindows calls curses_uncurse_terminal,
which calls endwin. curses_exit_nhwindows then calls raw_print,
which calls more Curses functions after endwin has been called.
Fix this by having curses_raw_print use puts if window_inited
is false.
* When dying, quitting, etc.: really_done opens the "Goodbye" window,
which refreshes the other windows when it closes. But the status
window (and possibly the map and message windows) are gone by that
point. The window pointers are properly NULLed, but the NULL is then
passed to touchwin. Fix this by checking window pointers for NULL.
set_tile_type frees tileset memory not in use for the current tile
type (paletted or full color).
stretch_tile and free_tile support resizing tiles at run time.
Some BIOSes allow calling the window function directly, bypassing the
logic that distinguishes this call from other BIOS calls. Should be
faster on some systems.
This was not previously done because the palette was not correctly set
up, and QEMU gave incorrect colors. The palette setup function now
falls back to the standard BIOS function if the VESA BIOS function
fails, which resolves the issue with QEMU. The mode selection logic now
favors 8 bit color if the tile set is compatible.
Using 8 bit mode means fewer writes to memory and fewer uses of the
BIOS window function.
