Running de1soc Vector_add example on de5-net

[Altera_Forum]

Hi, I was asked if I can run de1soc vector_add example on De5-net board. After I compile the Kernel when I type Make I get the following error :  

   arm-linux-gnueabihf-g++ host/src/main.cpp ../common/src/AOCL_Utils.cpp -o vector_add -I/opt/intelFPGA/16.1/hld/host/include -I../common/inc -L/opt/intelFPGA/16.1/hld/board/terasic/linux64/lib -L/opt/intelFPGA/16.1/hld/host/arm32/lib -Wl,--no-as-needed -lalteracl -lalterahalmmd -lterasic_apb_16_0_mmd -lelf -lstdc++  make: arm-linux-gnueabihf-g++: Command not found Makefile:41: recipe for target 'all' failed make: *** [all] Error 127   I would be thankful to get some help.

If you are trying to use the example shipped with the Terasic SoC board, it is obviously not going to work on DE5-Net since the latter is not an SoC board. The example will, by default, compile the host code for ARM, while for DE5-Net you should compile the host code for a standard x86/x64 CPU. 

 Use the x64 version of the benchmark provided here:  https://www.altera.com/support/support-resources/design-examples/design-software/opencl/vector-addition.html  P.S. The error you are getting above is due to the necessary ARM cross-compiler not being available on your system. You should install the necessary packages if you want to cross-compile for ARM. You can easily find the package names by searching google for the missing file. Obviously, this is not needed if you are targeting the DE5-Net board.

I have run DE5-Net test examples successfully on the Machine. But I was asked if it is possible to run de1soc test examples on DE5-Net. So based on your comments it is not possible. Is that correct?

You should modify the makefile so that the host compiler is changed from arm-linux-gnueabihf-g++ to g++, and the target board is de5net_a7 instead of whatever it is right now.

Should I delete Cross_compile ( green ) part ?   Thanks,

Changing the red part alone should be enough to fix the target compiler. You should also remove the --arm switches from "AOCL_COMPILE_CONFIG" and "AOCL_LINK_CONFIG".
