Hi,

Thanks, that helps. With there is maybe something to learn from the CMake

Hello,

according to https://sourceforge.net/p/predef/wiki/Compilers/ you could 
check with


check_cxx_source_compiles("
#if defined (_MSC_VER) && (_MSC_VER == 1900) && (_MSC_FULL_VER == 
190024210)

#else
  #error compiler is not MSVC Update3
#endif
int main() {
return 0;
}
" MSVC_UPDATE3_FOUND)

for the requested feature.

HTH, Cheers, Volker

Hello,

A question that will hopefully have a quick/easy answer:

I'd like to detect when the MSVC /fpermissive- (yes, that's a dash at the end) 
can be used instead of /Za . I know that a later update bumped the version to 
14.0.25422.01 and thus undoubtedly _MSC_FULL_VER== 1402542201 in C code so I 
could assume everyone keeps installs their updates and use that value.

But what does this translate to in CMake code (MSVC_VERSION)? Probably not just 
1903 I presume?

Thanks,
René

I forgot to mention: I don't have a MS dev set-up at the moment. This is for a 
cross-platform purposes (in KDE's extra-cmake-modules).

[CMake] How to detect MSVC 2015 update 3 (= presence of /fpermissive-)

2017-05-15 Thread René J . V . Bertin 
Hello,

A question that will hopefully have a quick/easy answer:

I'd like to detect when the MSVC /fpermissive- (yes, that's a dash at the end) 
can be used instead of /Za . I know that a later update bumped the version to 
14.0.25422.01 and thus undoubtedly _MSC_FULL_VER== 1402542201 in C code so I 
could assume everyone keeps installs their updates and use that value.

But what does this translate to in CMake code (MSVC_VERSION)? Probably not just 
1903 I presume?

Thanks,
René
