[ft-devel] porting: Where should i start debugging

[duhuanpeng]

Dear all,

I am porting freetype to a "bare or rtos" system. This system supports fat
file system and has "malloc" family routines.

Here is build log for this target:
https://paste.ubuntu.com/p/rxQsMTmtZV/

Here is build log on my pc, Ubuntu GNU/Linux:
https://paste.ubuntu.com/p/DjNkvGHPg3/

Here is my test program:
https://paste.ubuntu.com/p/Wm5hZtYt7p/

My Makefile on PC:

dump1: dump1.c
        gcc $<  -D__PC__ -L/home/du/source/freetype2/objs
-L/usr/lib/x86_64-linux-gnu -lfreetype -lz
-I/home/du/source/freetype2/include -I/usr/include/freetype2 -lm -o $@

But I can't get the correct font. This is the output when I use *Gb16st.pcf*
, Google driver:   goo.gl/ZWqa4d
