Gamelift c++ Sdk build errors (msbuild error)


Hello everyone.So i installed latest gamelift sdk for unreal engine.So as usual i should extract and take c++ sdk and need to run cmake and mbuild as well.

So first Phase:
I followed steps mentioned such as:
mkdir out
cd out
Cmake with Visual Studio 2019: cmake -G “Visual Studio 16 2019” -A x64 -DBUILD_FOR_UNREAL=1 …

Msbuild: msbuild ALL_BUILD.vcxproj /p:Configuration=Release

I ran the above commands.

I got an error like this:

In that it failed building boost engine.So by taking some advice i tried installing the boost library seperately.It said i have unknown compiler version error.I had visual studio 19 compiler version which doesn’t support that boost lib version 1.65.


Now i tried installing latest boost lib which is 1.75 and it installed perfectly.In cmake by using a flag to check existing boost library i passed cmake.But when i run msbuild i am getting error like this again.

So i am pretty much confused.So plz help me.Thank you
