Building Boost 1.69 with Visual Studio 1.69

[fibers] Great amount of errors...

Maybe I'm getting ahead of myself given the recent topic about picking a version number for the latest MSVC toolset but I'm having trouble building boost 1.69 with Visual Studio 2019 preview. I blindly assumed the toolset was 14.20 (given the directory where cl.exe is found). Letting b2 determine the version yields vc141 in the lib names. Trying to force 142 with: using msvc : 14.2 : <path to cl.exe> ; in project-config.jam yields errors about unescaped characters. Suggestions welcomed. Chris.

When building Boost with VS2019, for the time being,forget about the toolset name. Do not configure anything in user-config.jam or anywhere Launch VS2019 command prompt, then ./bootstrap.bat and run b2 In --layout=verioned build, it will generate libraries named with 'msvc-14.1'. Just accept that, ignoring the fact it mismatches the reality or build with --layout=system. I have managed to run MP11 and System tests https://gist.github.com/mloskot/4d34a6f6d0e60a543f2ed153af87dcd9 https://gist.github.com/mloskot/efbfb2b33c99b8f70cfe4f912a8ec4d6 I use VS2019 for Boost.GIL development, building required Boost libraries with b2 --with-filesystem --with-test --layout=system This way, GIL's CMakeLists.txt can detect the Boost libraries fine and I can build and run GIL tests i VS 2019.

Correct, as ever. Sadly, hoping it would 'Just work', as others suggested with user-config.jam using msvc : 14.1 ; using msvc : 14.2 ; didn't work for me. The log looked confused about both cl.exe and vsvarsall.bat. (I did a --clean and --reconfigure first to make sure) So, taking Steven's advice, I have now specified both compilers and both setups in my user-config.jam thus: using msvc : # Version VS 2017 14.1 : # Compiler location "C:/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Tools/MSVC/14.14.26428/bin/Hostx64/x64/cl.exe" : # Options <setup>"C:/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Auxiliary/Build/vcvarsall.bat" <define>BOOST_CONFIG_SUPPRESS_OUTDATED_MESSAGE # Needed if you are working on develop or master ahead of the latest release. ; # Used, for example, thus # b2 toolset=msvc-14.1 using msvc : # Version VS 2019 Preview 14.2 : # Compiler location "C:/Program Files (x86)/Microsoft Visual Studio/2019/Preview/VC/Tools/MSVC/14.20.27508/bin/Hostx64/x64/cl.exe" : # Options <setup>"C:/Program Files (x86)/Microsoft Visual Studio/2019/Preview/VC/Auxiliary/Build/vcvarsall.bat" <define>BOOST_CONFIG_SUPPRESS_OUTDATED_MESSAGE # Needed if you are working on develop or master ahead of the latest release. ; I:\boost\libs\hello_boost\example>b2 -a address-model=64 toolset=msvc-14.1,msvc-14.2 -d2 --debug-configuration > both_cl_setup.log runs with two promising messages: notice: will use 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.16.27023\bin\Hostx64\x64\cl.exe' for msvc, condition <toolset>msvc-14.1 notice: will use 'C:/Program Files (x86)/Microsoft Visual Studio/2019/Preview/VC/Tools/MSVC/14.20.27508/bin/Hostx64/x64/cl.exe' for msvc, condition <toolset>msvc-14.2 and two runs of vcvarsall.bat as expected.

Sadly, hoping it would 'Just work', as others suggested with user-config.jam

using msvc : 14.1 ; using msvc : 14.2 ;

didn't work for me.

Possibly, I run b2 from "x64 Native Tools Command Prompt for VS 2019 Preview", that is why that short definition for 14.2 in project-config.jam worked, obviously: I had been fiddling with that and possibly missed details about what actually worked.

...

<setup>"C:/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Auxiliary/Build/vcvarsall.bat"

I have just learned about the <setup> trick. This looks very useful! Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

You shouldn't need to put in the cl.exe path. B2 is supposed to find it on its own. -- -- Rene Rivera -- Grafik - Don't Assume Anything -- Robot Dreams - http://robot-dreams.net
