Without this Make variable, Objects.rules does not add font_fnt.o to the build, causing undefined reference to fnt_createfont at link time. Signed-off-by: Acfboy <AcfboyU@outlook.com>
…support for NuttX Build the Nano-X client library, server and (optional) built-in window manager from the bundled Microwindows tree Signed-off-by: Acfboy <AcfboyU@outlook.com>
* Port the nxcalc demo from Microwindows * Connects to the Nano-X server started by examples/nanoxterm * Requires CONFIG_LIBC_FLOATINGPOINT for the result formatting Signed-off-by: Acfboy <AcfboyU@outlook.com>
* Port the nxterm demo from Microwindows * Starts the Nano-X server as a separate task before connecting * Runs an NSH shell instance on a pseudo terminal in the forked child instead of exec /bin/sh (no filesystem binaries in flat builds) Signed-off-by: Acfboy <AcfboyU@outlook.com>

Thank you @Acfboy :-) For sure we need a documentation for that part :-) I just did a rewrite of components / graphics / nx, so other gfx components are in one place, like framebuffer, and maybe nano-x, will push in a free moment this week :-) |

* Introduce EXPORTED_INCLUDES in apps/Make.defs; every entry is prefixed with INCDIR_PREFIX and added to CFLAGS/CXXFLAGS so it takes effect in the in-tree build as well * The export target in apps/Makefile copies the content of the listed directories into the include directory of the export package, so out-of-tree applications built from the package can still find the public headers * graphics/microwindows registers microwindows/src/include through this mechanism in its Make.defs Assisted-by: OpenCode:DeepSeek-V4-Flash Signed-off-by: Acfboy <AcfboyU@outlook.com>
…h the server * Add CONFIG_MICROWINDOWS_NANOX_NONETWORK which builds the Nano-X client library and server in the linked-in (NONETWORK) mode, so client applications are linked directly with the server and run in the same task, requiring no network stack or socket at all * Reorganize the source lists: the drawing sources (nxdraw, nxutil, nxtransform, nxpaintnc) are shared by both modes, while the server is built from srvnet.c in the network mode and srvnonet.c in the NONETWORK mode * Use MULTITHREAD_SERVER in the network mode so that several client tasks can run at the same time in the flat build * Let the examples/nanoxterm start the server task only in the network mode (NONETWORK applications run the server inside main) Assisted-by: OpenCode:DeepSeek-V4-Flash Signed-off-by: Acfboy <AcfboyU@outlook.com>

Summary
This PR ports the Nano-X windowing system from Microwindows to NuttX so that X11-style client/server applications can run in a flat build. It contains three logical parts:
graphics/microwindows: build the Nano-X client library and server from the bundled Microwindows tree, with two new Kconfig options:MICROWINDOWS_NANOX: build the Nano-X client library and server.MICROWINDOWS_NANOX_NANOWM: optionally link the Microwindows window manager into the server so the server task draws and decorates windows itself.examples/nanoxcalc: port of the nxcalc demo. It connects to the running Nano-X server and shows a calculator keypad.examples/nanoxterm: port of the nxterm demo. It is a terminal emulator that opens a pseudo terminal, forks, and runs an NSH instance (nsh_consolemain) in the child instead of exec'ing /bin/sh, since flat builds have no filesystem binaries. It starts the Nano-X server as a separate task before connecting, so it can be used as the init entry point: booting sim:nanox opens the nxterm window directly, and typing nanoxcalc in it opens the calculator.Note
There are still some remaining issues, for example, have some problem when running on qemu, so this is just a draft PR. When it is fully ready, I will add the documentation and open it up for review.
