EASTL failed with error C2039 , C2065 when build with default by msvc on Windows

Hi all,

EASTL failed with error C2039 , C2065 when build with default by msvc on Windows.Could you please help take a look at this?

You can repro this issue as the steps below:
1.git clone https://github.com/electronicarts/EASTL F:\gitP\electronicarts\EASTL
2.cd F:\gitP\electronicarts\EASTL\build_x86
3.cmake -G "Visual Studio 16 2019" -A Win32 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 -DEASTL_BUILD_TESTS:BOOL=ON -DEASTL_BUILD_BENCHMARK:BOOL=OFF .. 2>&1
4.set CL=%CL% /Zc:static_assert-
5. msbuild /m /p:Platform=Win32 /p:Configuration=Release EASTL.sln /t:Rebuild 2>&1

Error info:
F:\gitP\electronicarts\EASTL\include\EASTL/numeric_limits.h(1684,20): error C2039: '_LDenorm': is not a member of '`global namespace'' [F:\gitP\electronicarts\EASTL\build_x86\EASTL.vcxproj]

Hello @nnfdnkns,

Thanks for the report. It seems like EAThread has some issues building for Win32 that we need to resolve to actually build EASTL as you describe, but after I hacked around EAThread a bit I was able to compile fine for Win32 on VS2019.

What you describe sounds a lot like what #474 was trying to resolve. I wonder if there's something we're doing incorrectly there.

Can you share the output of running cl /Bv on your system as described here to get some details on your toolchain?

In my system I can see all the variable declarations you're missing in C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Tools\MSVC\14.29.30133\include\ymath.h. Do you have an equivalent file under your VS installation?

These variables have been removed in a more recent version of MSVC's STL which I believe hasn't shipped, so I'm surprised you're hitting this. The newer version is supposed to be detected by the #if defined(_MSVC_STL_UPDATE) && _MSVC_STL_UPDATE >= 202206L in our EASTL\numeric_limits.h.

@grojo-ea Thanks for your quick reply. I have confirmed that this issue has been fixed after we updated the EASTL sha.

But now we still have other same problems as #371. This issue only occurs on x86 bit and we have patched it to unblock testing. Can you help fix it? Thanks.

I can repro the issue on VS2019 16.11.18 with the following build steps:

1. open VS2019 x86 native tools command
2. git clone https://github.com/electronicarts/EASTL F:\gitP\electronicarts\EASTL
3. cd F:\gitP\electronicarts\EASTL
4. git submodule sync
5. git submodule foreach git reset --hard
6. git submodule foreach git clean -xdf
7. git submodule update --init
8. mkdir build_x86 && cd build_x86
9. cmake -G "Visual Studio 16 2019" -A Win32 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 -DEASTL_BUILD_TESTS:BOOL=ON -DEASTL_BUILD_BENCHMARK:BOOL=OFF ..
10. msbuild /m /p:Platform=Win32 /p:Configuration=Release EASTL.sln /t:Rebuild
