Creating Libraries

Hello,
I have a big project and I need to isolate part of this project to my own library. When everything is together I don't have any problems.  But when I separate liblary files I have problem:

"
'Building target: lib.out'
C:/ti/ccsv6/tools/compiler/c6000_7.4.8//bin/cl6x -mv6600 --abi=eabi -O2 -g --machine_regs --

display_error_number --diag_warning=225 --interrupt_threshold=2000 --no_bad_aliases --

optimizer_interlist -k --c_src_interlist -z -mlib.map -iC:/ti/ccsv6/tools/compiler/c6000_7.4.8/lib -

iC:/ti/ccsv6/tools/compiler/c6000_7.4.8/include --reread_libs --warn_sections --rom_model -o

bin/lib.out  -l"libc.a" obj/f.obj obj/s.obj obj/t.obj
warning #10211-D: cannot resolve archive
<Linking>
   C:/ti/ccsv6/tools/compiler/c6000_7.4.8/lib/libc.a to a compatible library,

   as no input files have been encountered
>> Compilation failure
error #10198-D: no input section is linked in
warning #10062-D: entry-point symbol "_c_int00" undefined
warning #10202-D: no suitable entry-point found; setting to 0
error #10010: errors encountered during linking; "bin/lib.out" not built
gmake: *** [lib.out] Error 1"

How do I fix this?


I must say that all of objects are building correctly. Makefile for the library is similar to makefile
 for project.


Best Regards
