Hi,

I successfully tried to link the dsp library into my project as

-l ti/dsplib/lib/dsplib.lib in linker comman file.

Similarly i tried to link the math library to my project as

-l ti/mathlib/lib/mathlib.a66 but after compilation it is showing errors as,

undefined first referenced
symbol in file
--------- ----------------
atan2sp C:\ti\dsplib_c66x_3_4_0_0\packages\ti\dsplib\lib\dsplib.ae66<DSPF_sp_cholesky_cmplx.oe66>
cossp C:\ti\dsplib_c66x_3_4_0_0\packages\ti\dsplib\lib\dsplib.ae66<DSPF_sp_cholesky_cmplx.oe66>
sinsp C:\ti\dsplib_c66x_3_4_0_0\packages\ti\dsplib\lib\dsplib.ae66<DSPF_sp_cholesky_cmplx.oe66>

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "test_new_rxr.out" not built.

Please suggest me as i have got struck at this point of my project.

thanks & regards,

Hello,
Check the library format you are linking against. It should match your output format, either COFF or ELF. Would help if you paste your console output.

Hi Gopal,

In CCS, check out the properties of the project.

For example, C6000 linker --> FileSearch Path --> Add <dir> to library search path --> add using the option "+" "${MATHLIB_INSTALL_DIR}/packages".

something like below for your reference:

Shankari

Whether you have tried linking math library first and then dsp library? DSP library uses the functions from the Math library.

Hi shankari,
the problem has been solved, i included the library file in file search path as "C:\ti\mathlib_c66x_3_0_1_1\lib\mathlib.ae66". Now its working fine.
thanks&regards
