Dear list, I just tried to enable more warnings with Visual C++. According to INSTALL.cmake, it should be enough to set LYX_WALL to 1, but I get these warnings from the compiler:
cl : Command line warning D9002 : ignoring unknown option 'Wp64' In CMakeLists.txt:1091 to 1093, I indeed find that, with LYX_WALL, the parameter /Wp64 is used (it was deleted a few years ago: https://docs.microsoft.com/en-us/cpp/build/reference/wp64-detect-64-bit-portability-issues?view=vs-2019 ). The right flag is the one indicated in the documentation: /W4. Making the change locally seems to be right (VC returns more warnings for the code and none for its arguments). Was this /Wp64 intentional? It really seems odd there… In any case, I've added a patch for this fix, if it is welcome.
