Error building on Open Q 820 Snapdragon 820 Hexagon 3.2 when trying to compile and link the stub and skeleton

Question

I am trying to run the calculator example for Hexagon DSP SDK following the instructions in file:///C:/Qualcomm/Hexagon_SDK/3.2/docs/calculator_android.html

In the command line I have setup the sdk in the following way:

setup_sdk_env.cmd

I have cleaned and built the android module successfully

make tree V=android_Debug [CDSP_FLAG = 1]

But I have an error when trying to do it for the hexagon module.

make tree V=hexagon_Debug_dynamic [CDSP_FLAG = 1]

This is what I get:

C:\Qualcomm\Hexagon_SDK\3.2\examples\common\calculator>make tree V=hexagon_Debug_dynamic CDSP=1
making C:\Qualcomm\Hexagon_SDK\3.2/test/common/test_util
El sistema no puede encontrar la ruta especificada.

make: *** [MAKE_D_7_LIBDIR] Error 1

Note my computer is Spanish, "El sistema no puede encontrar la ruta especificada." means that the system was not able to find the specified path.

When you make the calculator and specify 'tree' the calculator's dependencies are also built. One of which is test_utils.

Could be a number of things

• tools are missing (compiler)
• test_utils are missing
• something else...

Next step is to run the command listed in make output by itself from the test_util directory to get more information on what is missing. (C:\Qualcomm\Hexagon_SDK\3.2/test/common/test_util)

"C:/Qualcomm/Hexagon_SDK/3.2/Tools/bin/hexagon-clang"  -mv60 -c -v -G0 -g -O0  -Wall -Werror -Wno-cast-align -Wpointer-arith -Wno-missing-braces -Wno-strict-aliasing  -fno-exceptions -fno-strict-aliasing -fno-zero-initialized-in-bss -fdata-sections -mllvm -disable-hsdr -fpic -D__V_DYNAMIC__ -Wstrict-prototypes -Wnested-externs      -D__FILENAME__=\"test_utils.c\" -D_DEBUG  -Iinc -Isrc -IC:\Qualcomm\Hexagon_SDK\3.2/incs -IC:\Qualcomm\Hexagon_SDK\3.2/incs/stddef -Ihexagon_Debug_dynamic  -o hexagon_Debug_dynamic/test_utils.o src/test_utils.c

• check that clang exists
• check that test_utils directory and required files below it exist
