Please install required libs for OpenCL SDK. check it with intel's latest user manual.

[thinkoco]

@rvakash Yes,it should be make first in the IP core file.

[rvakash]

@thinkoco There is no Makefile inside the IP core. Inside the RTL folder there is a Makefile which I have compiled and generated the rtl_lib.aoclib and rtl_lib.aoco files.

[doonny]

@rvakash please use the makefile provided. Your compile command is not correct.

[rvakash]

Hi,
Thanks, I was able to run it on the emulator with the Makefile provided.
But with fpga I am getting -
aoc: First stage compilation completed successfully.
Error: Compiler Error, not able to generate hardware

I have changed FLOW = hw in Makefile. Anything else I need to change ?

[rvakash]

I am getting the following error -

Thank you

[rvakash]

Hi, I was able to generate the conv.aocx file. When I run it I am getting a new error.

pnirali@harp8:/data/05297/pnirali/PipeCNN2/project$ ./run.exe conv.aocx
./run.exe: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ./run.exe)

I am using gcc-4.8.4

[arun0303]

hi Prof Doony,
I am also having the same error while running the file in DE10 Standard kit
./run.exe conv.aocx
./run.exe: libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./run.exe)
I had installed all the required libs as mentioned in intel latest manual.
Kindly help me with this issue

[Frankzd]

Hi @rvakash I am facing the same problem that you met before

do you remember how to solve it?

I am using PAC_A10 and SDK 17.1 by the way.
