vadd host binary compilation error

[vkomenda]

Do you know how to fix the following compilation error? I'm trying to build the vadd host binary.

$ g++ -o vadd -O2 vadd.cpp vadd-host.cpp -l:libtapa.a -lfrt -l:libglog.so.0.4.0 -lgflags -lOpenCL -lpthread -ldl -lboost_context -I${HOME}/Xilinx/Vitis_HLS/2022.1/include -g

I think this is caused by a version mismatch between the glog library and the glog header. The glog 0.4.0 library takes an int for the 4th argument, but apparently the header is expecting a long. Could you check which glog/logging.h is being included?

Thanks! That was indeed a wrong header file. I switched to using glog v0.4 compiled from source to fix that.
