Hi @Bhimrao.Ghule

Have you confirmed the required libraries e.g. if I check the Additional Dependencies under Linker->Input for the ETA example VAConsumer, I see the following:

\RTSDK-2.0.1.L1.win.rrg\Cpp-C\Eta\Libs\WIN_64_VS142\Debug_MDd\librsslVA.lib\RTSDK-2.0.1.L1.win.rrg\RTSDK-BinaryPack\Cpp-C\Eta\Libs\WIN_64_VS142\Debug_MDd\librsslVACache.lib
wininet.lib
ws2_32.lib
crypt32.lib
cryptui.lib
Iphlpapi.lib
\RTSDK-2.0.1.L1.win.rrg\Cpp-C\Eta\Libs\WIN_64_VS142\Debug_MDd\librssl.lib
kernel32.lib
user32.lib
gdi32.lib
winspool.lib
shell32.lib
ole32.lib
oleaut32.lib
uuid.lib
comdlg32.lib
advapi32.lib

Based on my experience with similar linker errors in the past, I suspect you are missing wininet.lib (if not others)

You can also check the CMakeLists.txt in the \Cpp-C\Eta\Impl\Reactor\ folder to help identify the libraries required for your particular build environment.

Thanks @umer.nalla

It was because of Iphlpapi.lib and wininet.lib
