Thanks @Acfboy . When I disable HAVE_FILEIO in `mwfont_findalias` then the
Nano-X terminal and caclc works on x86_64 QEMU and even windows manager allows
windows moves etc. great.
```
char *
mwfont_findalias(const char *fontname, int *height, int *width)
{
#if HAVE_FILEIO_DISABLE_THERE
```
The next change
```diff

```
helps as well. But it seems as some bug in NuttX or some overflow in
stack/too small stack allocated that `task_get_info` returns -1. Or TLS is
rewriting task info. I will look at it more when I return from trip.
I suggest to keep `NONETWORK` as configurable in KConfig or other way. For
minimal setup it has value, for larger it worth to be available for multiple
applications to work and even MMU mode in future. In the fact the Microwindows
config file `microwindows/src/include/mwconfig.nuttx` is generated and ten
pointed by `MWCONFIG_FILE` so it would reflect what is setup in Kconfig. But I
am not sure if introduce this now or leave it simpler at the start.
What I see as think to solve is export of component includes files during
export. It is think to solve for more NuttX APPS components.
I think that `Make.defs` should not directly define includes in CFLAGS
```
CFLAGS +=
${INCDIR_PREFIX}$(APPDIR)/graphics/microwindows/microwindows/src/include
CXXFLAGS +=
${INCDIR_PREFIX}$(APPDIR)/graphics/microwindows/microwindows/src/include
```
But there should be some other variable to collect includes, i.e.:
```
EXPORTED_INCLUDES +=
${INCDIR_PREFIX}$(APPDIR)/graphics/microwindows/microwindows/src/include
```
Which would be converted by substitution to `CFLAGS` and `CXXFLAGS ` options
`-I` for in-tree build and which would be iterated during export and content
of listed directories would be copied into export archive. I have discussed
that with @michallenc so he can provide some idea as well.
