Other Parts Discussed in Thread: SYSBIOS
Hello all,
I have made a RTSC package for math functions using the fastFPUmath library in control suit. The new package is building properly in the command window. For testing this package i imported this package to my sysbios project. I am getting unresolved symbol errors when i build my project in ccs. I am attaching the console output, math package, test program in ccs and the problems tab.

var LIB_NAME = "lib/" + Pkg.name;

for each (var targ in Build.targets) {
Pkg.addLibrary(LIB_NAME, targ, {incs: "-I D:/ti/ccsv5/tools/compiler/c2000_6.1.0/include"}).addObjects(LIB_SRCS);

As you can see "all files completed" from the concole
now for testing this package, I added the repository directory to my CCS 5 project. I am receiving few unresolved symbol errors when i build the project
I am using Concerto Experimenter Kit F28M35H52C1, and my project sysconDSP is running on the DSP side of the concerto, withsysbios V. 6.33.4.39
the compiler used is c2000_6.1.0
I am attaching my sysconDSP_main.c, which contains the code to test the Math functions in the Math package i just created.

y_abs_Math=Math_abs(x_abs);
y_sqrt_Math=Math_sqrt(x_sqrt);

y_sin_Math= Math_sin(x_sin);
y_cos_Math= Math_cos(x_cos);
// IPCInit ();
BIOS_start(); /* enable interrupts and start SYS/BIOS */
}
When i try to build the following i get few unresolved symbol errors , I am attaching screen shot of the "Problems" tab
