Description Thomas Frosio 2023-12-15 06:08:24 CET

When trying to compile on windows MSBuild version 17.8.3+195e7f5a3 for .NET Framework, the following error happens:

D:\MicrosoftVisualStudio\2022\Community\VC\Tools\MSVC\14.38.33130\include\xlocnum(1398,76): error C2039: '_finite': is
not a member of 'std' [D:\Libraries\GEANT4\geant4_build_windows\source\G4processes.vcxproj]

This issue is solved by changing the following:
1) In geant4/source/processes/hadronic/models/lend/src/nf_stringToDoubles.cc, replace line 13 by   #define isfinite isfinite instead of   #define isfinite _finite
2) In geant4/source/processes/hadronic/models/lend/include/nf_specialFunctions.h, replace line 14 by   #define isfinite isfinite instead of   #define isfinite _finite

The same might be necessary in geant4/examples/extended/electromagnetic/TestEm7/include/c2_function.hh line 48 but I did not test the compilation of this example.

Best regards,
Thomas

I forgot to mention that the issue is encountered with the last G4 version 11.2.0
