Hi all,
I am experimenting with nano-X on my development environment first, which
is the following:
- Ubuntu 8.04, on a VMWare virtual machine
- gcc 4.2.3
- zlib: 1.2.3.3
Building microwin on X went ok, after two small, superficial code changes.
I wasn't able to compile flnx samples, kept getting things like:
----------------------------
g++ -I.. -O2 -Wall -Wno-return-type -DNANO_X
-I/home/jorge/LCD/microwindows-latest/src/include
-DNANOXFOLDER='"/home/jorge/LCD/microwindows-latest/src/bin"' -DPDA
cube.cxx -L../lib -lfltk -lnano-X -DNANO_X=1 -L/usr/local/lib
-L/home/jorge/LCD/microwindows-latest/src/lib -lnano-X -lm -o cube

`getsyscolor(char const*, void (*)(unsigned char, unsigned char,

`XParseColor'
-----------------------
Why does that happen? Anyway, I used fltk-1.1.9 (latest stable release) on
top of nxlib. Everything went ok in the build. By means of LD_LIBRARY_PATH
I was able to test fltk samples both with and without microwin. I tested
four builds of microwin, obtained by varying two parameters: (i) version -
microwin-0.19 versus the more recent snapshot available via ftp - and (ii)
HAVE_PCFGZ_SUPPORT. Here is what I observed:
1 - I could see no difference between versions, except when running Fluid
itself on nano-X, which does not work well anyway, but looks worse on
0.19;
2 - no windows could be resized nor moved, which is possible without nano-X;
3 - on nano-X, the samples respond to the keyboard, but in a completely
wrong manner. For example, when typing text in a textbox, characters do
appear, but obeying a messed-up keyboard map;
4 - when HAVE_PCFGZ_SUPPORT=Y, nano-X dies in fltk-1.1.9 sample "tile"
with the following messages:
----------------
createfont: (height == 0) found builtin font System (0)
createfont: (height == 0) found builtin font System (0)
fnt_createfont: /usr/share/fonts/X11/100dpi/helvR12-ISO8859-1.pcf.gz,0
not found
Segmentation fault
----------------
5 - when HAVE_PCFGZ_SUPPORT=n, nano-X works, but it seems that the font
cannot be loaded. As a result, text is written in just one size, while the
application originally specifies various sizes. Here are the messages
nano-X generates:

Thanks in advance for any pointers.
