RTL kernel flow: undefined reference to xrt::<>

[andy39866821]

Hi,

My operating system is CentOS-7, with Vitis 2021.2

I am trying to compile user-host.cpp in Vitis-Tutorials/Hardware_Acceleration/Feature_Tutorials/01-rtl_kernel_workflow/reference-files/src/host, which is cloned from latest Vitis tutorial webpage.

Here is my compiling command for host program of RTL kernel, refer from link:

g++ -g -std=c++14 -I$XILINX_XRT/include -L$XILINX_XRT/lib -o host.exe user-host.cpp -lxrt_coreutil -pthread

And it shows that I have some errors:

/tmp/ccLPWVLK.o: In function `main':
<root>/Vitis-Tutorials/Hardware_Acceleration/Feature_Tutorials/01-rtl_kernel_workflow/reference-files/src/host/user-host.cpp:43: undefined reference to `xrt::xclbin::xclbin(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

[Solved]

Thanks to TA 趙德昊, this issue is due to different g++ versions when installing,
Use the command below to change the g++ version to 9.3.1.
scl enable devtoolset-9 bash
