FLTK-utf8 中文顯示 by gziped pcf fonts

1.Requirement

nano-X support GZIP PCF fonts

字型可用firefly

http://cle.linux.org.tw/fonts/FireFly/bitmaps/pcf/fireflyR11.pcf.gz
http://cle.linux.org.tw/fonts/FireFly/bitmaps/pcf/fireflyR12.pcf.gz

http://cle.linux.org.tw/fonts/FireFly/bitmaps/pcf/fireflyR16.pcf.gz

在PC上產生fonts.dir在加以修改

[gigijoe@localhost fonts]$ ls
fireflyR13.pcf.gz fireflyR16.pcf.gz
[gigijoe@localhost fonts]$ mkfontdir
[gigijoe@localhost fonts]$ cat fonts.dir

fireflyR16.pcf.gz -firefly-firefly new sung-medium-r-normal--16-150-75-75-p-159-iso10646-1

修改成

fireflyR13.pcf.gz -firefly-sung-medium-r-normal--13-120-75-75-p-129-iso10646-1
fireflyR16.pcf.gz -firefly-sung-medium-r-normal--16-150-75-75-p-159-iso10646-1

Build nxlib-0.45

1.Modify Makefile

MWIN=../microwindows-0.91/src

X11_INCLUDE=$(X11)/include

CC = mipsel-linux-gcc

CFLAGS += -G 0 -Wall $(DEBUG) -I$(MWIN_INCLUDE) -I$(X11_INCLUDE)

xCFLAGS += -G 0 -O2 -fno-strength-reduce

libnx11.a: keysymstr.h $(OBJS)
mipsel-linux-ar r libnx11.a $(OBJS)


Add Selection.o to $OBJS


Modify


#      perl ./keymap.pl $(X11_INCLUDE)/X11 > ./keysymstr.h


         perl ./keymap.pl . > ./keysymstr.h



2. CFLAGS="-D_XP_PRINT_SERVER_" make


3.http://www.linuxhacker.org/cgi-bin/ezmlm-cgi/5/11115


 




 


FLTK with nxlib and nano-X

1.Modify configure.in
# LIBS="$LIBS -lXext -lX11 $X_EXTRA_LIBS"

If static link
LIBS="$LIBS -lnx11 -lnano-X $X_EXTRA_LIBS"

If dynamic link
LIBS="$LIBS -lX11 -lnano-X $X_EXTRA_LIBS"


2.Fix
Compiling Fl_x.cxx...
Fl_x.cxx: In function `int fl_wait(double)':
Fl_x.cxx:238: error: impossible constraint in `asm'
Fl_x.cxx:239: error: impossible constraint in `asm'
Fl_x.cxx:240: error: impossible constraint in `asm'
make[1]: *** [Fl_x.o] Error 1

The problem casue by reference to host header file.
Remove -I/usr/include to solve it.

Because we need X header files
cp -a /usr/include/X11 /usr/local/MIPSEL/mipsel-linux/include/

Add config param --x-include=-Iinclude

3.Configure
CFLAGS="-G 0" CXXFLAGS="-G 0" LDFLAGS="-s -L$PWD/../nxlib-0.45 -L$PWD/../microwindows-0.91/src/lib" ./configure --host=mipsel-linux --target=mipsel-linux --enable-shared --with-x --disable-gl --disable-cygwin --x-includes=include/ --x-libraries=$PWD/../nxlib-0.45 --cache-file=/dev/null

Fix ar in makeinclude
LIBCOMMAND = mipsel-linux-ar cr
Fix strip in makeinclude
STRIP = mipsel-linux-strip

4.make

5.Fix
Linking fluid...
../lib/libfltk.a(Fl_x.o)(.text+0x1420): In function `Fl::paste(Fl_Widget&, int)':
: undefined reference to `XConvertSelection'
../lib/libfltk.a(Fl_x.o)(.text+0x1624): In function `Fl::copy(char const*, int, int)':

collect2: ld returned 1 exit status

Append the following to nxlib-0.45/stub.c
/* required for FLTK 1.1.7*/
int XConvertSelection() { printf("XConvertSelection called\n"); return 0; }
int XSetSelectionOwner() { printf("XSetSelectionOwner called\n"); return 0; }

6.vi test/Makefile

Mark following item

# fast_slow(EXEEXT) \
# keyboard$(EXEEXT) \
# mandelbrot$(EXEEXT) \
# preferences$(EXEEXT) \
# radio$(EXEEXT) \
# resize$(EXEEXT) \
# sudoku$(EXEEXT) \
# tabs$(EXEEXT) \
# valuators$(EXEEXT)

7.Copy shared library to lib/
cp src/*.so.*  lib/

8.make again to let demo programs on test/ as dynamic link

9.Library needed
/tmp # /lib/ld-2.2.5.so --list ./utf8
