To compile the example code, run_bitacc_cmodel.c , first ensure that the directory in which the files libIp_xfft_v9_1_bitacc_cmodel.so and libgmp.so.11 are located is present on your $LD_LIBRARY_PATH environment variable. These shared libraries are referenced during the compilation and linking process.
Place the header file and C++ source file in a single directory. Then in that directory, compile using the GNU C++ Compiler:
gcc -x c++ -I. -L. -lIp_xfft_v9_1_bitacc_cmodel -Wl,-rpath,. -o
