Thanks for the clarification, I will stick then to MSBUILD/Visual.
I can see that ROOT is built with Visual Studio 2019. Unfortunately our project uses Visual 2017.
Did someone try to build ROOT with Visual Studio 2017 ?
I browsed through several threads and started to compile ROOT.
Unfortunately, I hit this error about \typetraits.hxx which seems to have already been reported
Line 13707: 4>d:\s\alamos-9.3.0\sources\root\core\foundation\inc\root\typetraits.hxx(43): fatal error C1001: Une erreur interne s’est produite dans le compilateur. [D:\S\ALAMOS-9.3.0\BUILD\root\core\BaseTROOT.vcxproj]
Thanks for your patience.
