No support for msvc-toolset 14.4x (VS 2022, 17.10.x)

[pdeiml]

This issue does not happen if one updates the Visual Studio version from e.g. 17.8 to 17.10. It happens if Visual Studio 17.10 is the only Visual Studio version which has been installed on the system. See end of this comment for further details.

As the title says boost is not compilable with Visual Studio 17.10.x. This is most likely due to the minor version of the msvc-compiler and -toolst which jumps from version 14.3x (VS 17.8.x) up to 14.4x (VS 17.10.x). This is described by Microsoft in msvc-toolst-minor-version-number-14-40.
I think that a commit similar to Add VC143, aka VS2012, aka cl.exe 17.x toolset. might fix this.

If one updates Visual Studio from e.g. 17.8 to 17.10 this problem will not occur because on the system there still will be the msvc-toolset 14.3x from the previous Visual Studio Version. If one completely deinstalls previous Visual Studio versions before the installation of Visual Studio 17.10 or one has an empty system and Visual Studio 17.10 is the first and only version which is installed then there will only be msvc-toolset version 14.4x and the compilation will fail.

Workaround that fixes it for me

Install MSVC v141 - VS 2017 C++ x64/x86 build tools (v14.16)

[sodevel]

AFAIK a standard installation of Visual Studio only keeps the latest MSVC runtime, so you will always run into this issue if you update to version 17.10 because this version ships with MSVC runtime 14.4x. The best workaround is to install a MSVC runtime 14.3 in parallel for your Visual Studio 17.10, b2 should be able to pick it up (i haven't tested this though, if that fails, you can try and change the default runtime version to 14.3). The issue here is, that the first 3 numbers of the MSVC runtime version (14.4) are not identical to the toolset version which is still v143.

Interestingly, bootstrap.bat is not affected by this issue and does work with MSVC runtime 14.4, it is only b2 which does not. I tried to work around this by setting up the environment manually with VsDevCmd.bat, using a non-existing toolset version like toolset=msvc-0.0, but nothing works, b2 never finds a matching compiler.

[pdeiml]

@sodevel I am confused about the runtime- and toolset-version.
I locally played around and changed files in analogy to Add VC143, aka VS2012, aka cl.exe 17.x toolset. and these locations correspond to the toolset version (there are comments and the names of the variables suggest that). With these changes I can build the parts of boost which I need.
But if I understand you correctly the toolset version is still 14.3. But why does it then work if I change the locations which correspond to the toolset version? Or do these locations affect both, the toolset- and the runtime-version?
Sorry if I understand something completely wrong.

[sodevel]

All this versioning is quite confusing, to use a common naming, i am going to use the names from this website https://reactos.org/wiki/Visual_Studio_Versions.

Before VS version = 17.10.z we had the situation that always Toolset version = 143 and MSVC version = 14.3x.yyyyy. Since VS version = 17.10.z we have the situation Toolset version = 143 and MSVC version = 14.4x.yyyyy. Now if you use b2 with toolset=msvc-14.4 it complains it cannot setup the compiler (i think, i can't remember fully and don't have access to the system right now, maybe it was bootstrap.bat that wasn't able to setup the compiler and b2 always failed in the same way), if you use toolset=msvc-14.3 it got further, but later the configure stage can't find a matching compiler.

However, b2 is smart, if you have still somewhere on your system a MSVC version = 14.3x.yyyyy available it will work even with VS version = 17.10.z. It will only error out if you only have MSVC version = 14.4x.yyyyy. I don't know what you did and how your system is setup, but are you sure that after your changes b2 actually did use a MSVC version = 14.4x.yyyyy runtime?

Edit: After re-reading your initial post i figured out i apparently described the same thing, just with more numbers. But i still don't understand what you changed, your link shows how support for a new Toolset version was added, but this is not necessary here, this version did not change.

[pdeiml]

Hey @sodevel ,
thank you very much for your detailed answer that smooth out all misunderstandings about the versions and the difference between toolset- and runtime version.
On my machine only VS 17.10.z is installed and building boost crashed. Then I did changes in analogy to the commit cited above in which the toolset version changed from 14.2x to 14.3x. Then it worked and I was happy :-)
After reading your comment I am confused as well that it worked correctly because you are completely right. I changed the parts of boost which are about the toolset version which did not change in the minor version.

I do not have such an insight knowledge about bootstrag and b2 and boost as you have it. But is it correct that one needs to make a commit in boost to support the case if only VS 17.10.z is installed? Because if I understand you comment correctly in this case b2.exe will error out, won't it?

[sodevel]

I am also just a regular user and these are my observations, i only got some extra explanations for these from comments inside tools/build/src/tools/msvc.jam. On my system with only MSVC version = 14.4x.yyyyy available couldn't get b2 running, so yes, i think something in b2 needs to be changed.

As an alternative you can build boost with CMake, the maintainers of the CMake build system and winapi library just made the required additions so that a CMake-build can act as a drop-in replacement for a b2-build (at least a rather default build of boost, maybe some configuration options are not available).

The generate-setup-cmd() helper in msvc.jam seems to be the culprit, at least in boost_1_82_0. The following patch fixed it for me:

[kislinsk]

I can confirm that the fix from @ifilippov-pgi worked for us. I applied it to Boost v1.85 and built with Visual Studio 2022 v17.10.1.

[ifilippov-pgi]

There seems to be a caveat if you are using autolinking, though.

If you specify a toolset when calling b2.exe, toolset = msvc-17.0, msvc-14.4, or msvc-14.3 all resolve to Visual Studio 2022 during the build process as expected. However, the compiled binaries will result in different tags: *-vc170-*.lib, *-vc144-*.lib, and *-vc143-*.lib.

vc170 and vc144 seem to break autolinking because linker will be looking for the vc143 tagged libraries even in VS 2022, 17.10. So you might want to make sure to use toolset = msvc-14.3.

Probably some additional updates are needed to the boost headers now that Visual Studio and its toolset versions started to diverge.

[mwestphal]

the patch from @ifilippov-pgi seems to works on our case too, with boost 1.83 build with MSVC 1940 (14.4).

[sodevel]

Looks like this was already fixed in the b2 build system, see bfgroup/b2#394

[MarcinLisowski]

I can confirm it's fixed by b2 5.2.1 - already checked that on my side. This version is already used on boost master branch, do we know when can we expect a release with it?

how to employ b2 5.2.1 in the building

[AraHaan]

For some reason when I try the downloaded 1.85.0 zip release file b2.exe on me says no to everything and I have all the major versions of VS installed including:

• VS2010 (10.x)
• VS2012 (11.x)
• VS2013 (12.x)
• VS2015 (14.x)
• VS2017 (15.x)
• VS2019 (16.x)
• VS2022 Preview (17.11+)

I have the same problem

[sodevel]

Whatever your problem is, it is unrelated to this issue, this issue is about b2 not working with a runtime version of 14.4+.

Good fix for the boost 1.85 with MSVC 17.10.5

[fschlaef]

I am having the exact same issue on Windows 10 with Visual Studio 17.11.2

[sodevel]

Use Boost 1.86.0 and your issue is gone

[fschlaef]

Use Boost 1.86.0 and your issue is gone

Couldn't do that because OpenUSD doesn't support it, but I noticed Boost 1.86.0 itself compiles with no issue 👍
