[ft] Error when trying to link Freetype library

I'm not sure that this is the proper place to ask but I do it anyway
as I desparately need some help. I'm trying to compile and test
Freetype on a embedded system, an ARM-processor running ThreadX but my
problem is on the compile-stage. My dev-box is running a cygwin-based
shell and after some problems I succeded (with the help of this great
) compiling freetype2 by first making a file named 'lib' in the
freetype-dir containing:

builds/unix/libtool --mode=finish $@

After making that one I call 'sh configure' and compile with 'make'.
This gives me a nice libfreetype in my objs/.libs/ directory.

After that I follow this tutorial and
include the following in my code:

#include <ft2build.h>
#include FT_FREETYPE_H


FT_Library  library;
FT_Error error;


error = FT_Init_FreeType( &library );
if ( error )

I also change the necessary changes in the makefile and the resulting
call to gcc is (I cut out some other includes to other libs that I
have succeded to include before adding freetype):

/usr/bin/arm-elf-gcc -o image.elf ./objs/appconf_api.o ./objs/root.o  
 -mbig-endian -nostartfiles \
-T ../../../../src/bsp/platforms/CPM4_R01/image.ld
../../../../lib/32b/gnu/crt0.o \
-Wl,--start-group ../../../freetype/objs/.libs/libfreetype.a -L
../../../../lib/32b/gnu -lc -lgcc -lm -lstdc++  -Wl,--end-group \

This returns the following error:

./objs/root.o(.text+0x14c): In function `applicationStart':
/src/apps/testfont/32b/../root.c:199: undefined reference to
`FT_Init_FreeType' make: *** [image.elf] Error 1

It looks like I havn't succeeded to include freetype properly, but the
path should be correct. It might also be some error with the #include
FT_FREETYPE_H not resulting in including the right files. I would
appreciate some help if anyone has any suggestions.
