hi all,
I try to use c64plus-imglib and install c64plus-imglib_2_02_00_00.
and try \test_drivers\drivers\IMG_sobel_3x3_8 example to test imglib can work or not.
I created an c6000 SYS/BIOS CCS example project in CCS5.1.
then copy the IMG_sobel_3x3_8_d.c in c64plus-imglib_2_02_00_00\test_drivers\drivers\IMG_sobel_3x3_8.
then add the IMG_sobel_3x3_8_idat.c and IMG_sobel_3x3_8_odat.c into the project.
it can run but had problem when execute the following code.
/* run the testcase */
t1 = clock();
IMG_sobel_3x3_8 (src_ptr, output_ptr, cols, rows);
t2 = clock();
the t1, t2 return 0;
and IMG_sobel_3x3_8 function can't work.
Is it an linking problem?
the following code is the test code source.
