You can compile the host application by following the typical cross-compilation flow for the Cortex A72 processor. To build the application, run the following command

make application 



aarch64-xilinx-linux-g++ -mcpu=cortex-a72.cortex-a53 -march=armv8-a+crc -fstack-protector-strong \
   -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=$(SDKTARGETSYSROOT) -O -c \
   -std=c++14 -D__linux__ \
$(HOST_APP_SRC)/main.cpp -o $(BUILD_TARGET_DIR)/gemm_top_app.o \
   -L$(SDKTARGETSYSROOT)/lib -lxrt_coreutil

aarch64-xilinx-linux-g++  -mcpu=cortex-a72.cortex-a53 -march=armv8-a+crc -fstack-protector-strong \
   -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=$(SDKTARGETSYSROOT) \
   $(BUILD_TARGET_DIR)/gemm_top_app.o -L$(SDKTARGETSYSROOT)/usr/lib -lxrt_coreutil \
   -o $(BUILD_TARGET_DIR)/gemm_dsp_xrt.elf

See this page for XRT documentation. See this page for details of host application programming.

Switch Description
-O | Optimize. Optimizing compilation takes somewhat more time, and a lot more memory for a large function. With -O, the compiler tries to reduce code size and execution time, without performing any optimizations that can take a great deal of compilation time.
-DXAIE_DEBUG Enable debug interface capabilities where certain core status, event status, or stack trace can be dumped out.
-D\<Pre-processor Macro String>=\<value> Pass Pre-processor Macro definitions to the cross-compiler.
-I \<dir> Add the directory dir to the list of directories to be searched for header files.
-o \<file> Place output in file <file>. This applies regardless of the output being produced, whether it be an executable file, an object file, an assembler file or preprocessed C code.
--sysroot=\<dir> Use dir as the logical root directory for headers and libraries. For example, if the compiler would normally search for headers in /usr/include and libraries in /usr/lib, it will instead search dir/usr/include and dir/usr/lib. This is automatically set by the script
-l\<library> Search the library named library when linking. The 2D-FFT tutorial requires adf_api_xrt and xrt_coreutil libraries.
-L \<dir> Add directory <dir> to the list of directories to be searched for -l.

The following is a description of the input sources compiled by the cross-compiler compiler command.

Inputs Sources Description
$(HOST_APP_SRC)/main.cpp Source application file for the gemm_dsp_xrt.elf that will run on an A72 processor.
$(HOST_APP_SRC)/matrix_A_data.h, matrix_B_data.h Matrix A and B Data to be used for matrix multiplication.
$(HOST_APP_SRC)/output_data.h Golden data to which DUT output will be compared.

The following is a description of the output objects that results from executing the cross-compiler command with the above inputs and options.

Output Objects Description
$(BUILD_TARGET_DIR)/gemm_dsp_xrt.elf The executable that will run on an A72 processor.
