I have built an older version of cairo without dependencies by stripping
the font calls completely (compiled for Analog Devices' Blackfin DSP
using their VisualDSP++). However, these sources now live on some
back-up CD and are no longer on my systems (but stuck in a box).
In my current work, I stripped down Freetype, though this is targetted
at a Pentium 4 platform.
Here is a snippet of the build script for Freetype:
----><----
tar xjf freetype-2.1.10.tar.bz2
...
# switch order of CFLAGS and INCLUDE_FLAGS, so that we can pass the
'custom' include
# directory to override Freetype configuration
sed -i -r 's at FT_CFLAGS.*=.*@FT_CFLAGS = $\(CFLAGS\)
$\(INCLUDE_FLAGS\)@g' builds/freetype.mk
# Remove functionality from Freetype
rm -rf
src/{bdf,cache,cff,cid,gzip,lzw,otvalid,pcf,pfr,psaux,pshinter,psnames,raster,tools,type1,type42,winfonts}
./configure --host=${TARGET} --prefix=/usr CFLAGS="-march=pentium4\ -g"
CPPFLAGS="-I../custom"
make
----><----
and ftmodule.h:
----><----
FT_USE_MODULE(autofit_module_class)
FT_USE_MODULE(tt_driver_class)
#if 0
FT_USE_MODULE(t1_driver_class)
FT_USE_MODULE(cff_driver_class)
FT_USE_MODULE(t1cid_driver_class)
FT_USE_MODULE(pfr_driver_class)
FT_USE_MODULE(t42_driver_class)
FT_USE_MODULE(winfnt_driver_class)
FT_USE_MODULE(pcf_driver_class)
FT_USE_MODULE(psaux_module_class)
FT_USE_MODULE(psnames_module_class)
FT_USE_MODULE(pshinter_module_class)
FT_USE_MODULE(ft_raster1_renderer_class)
#endif
FT_USE_MODULE(sfnt_module_class)
FT_USE_MODULE(ft_smooth_renderer_class)
#if 0
FT_USE_MODULE(ft_smooth_lcd_renderer_class)
FT_USE_MODULE(ft_smooth_lcdv_renderer_class)
FT_USE_MODULE(otv_module_class)
FT_USE_MODULE(bdf_driver_class)
#endif
----><----
Regards,
Leon.
