28 Ιουν 2016 · This doesn't seem to be reliable, as it is C++1z, not C++17. these slides had some features missing elsewhere. While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++: Removed: register, keyword reserved for future use; bool b; ++b; trigraphs
15 Αυγ 2017 · A certainly pedantic comment is that I consider this a bug in cmake: when I ask for C++11, C+14, C++17 I want cmake to set all flags that are needed to make the compiler conform, and that includes the value of the __cplusplus macro.
21 Ιουλ 2020 · For example, to compile hello.cpp with GCC for C++17: $ g++ -std=c++17 hello.cpp You ought to check how to pass compiler flags (or set options) in your IDE / editor / build system.
@alfC #if __cplusplus > 201402L would be true on c++1z, 17, currently 2a... and so on, but not c++14 or before that. In other words, this can be useful when using any old compiler before March 2017, given that you are using a ready-to-use feature of the c++17 that the old compiler already provides.
21 Μαρ 2018 · In another issue, it is said that the extension defaults to C++17, but does not yet support all of C++17 features: Setting C++ standard. This is confirmed by c_cpp_properties.json Reference Guide, where an option is listed cppStandard which defaults to C++17. (To edit this file, press Ctrl + Shift + P and type in C/CPP: Edit Configurations).
17 Ιαν 2016 · Those are pretty hacky and rely on "deprecated", "C++" and/or "C" (note the space at the end of grep "C "!) appearing in the help description for each standard name but they seem to work. You could similarly filter out e.g. "same as" to get rid of synonymous ones, etc.
When you do your #includes in file main.c, add the #include reference to the file that contains the referenced function at the top of the include list. E.g., say this is main.c and your referenced function is in file "SSD1306_LCD.h":
24 Φεβ 2010 · C++17: __cplusplus is 201703L. C++20: __cplusplus is 202002L. C++23: __cplusplus is 202302L. If the compiler might be an older gcc, we need to resort to compiler specific hackery (look at a version macro, compare it to a table with implemented features) or use Boost.Config (which provides relevant macros). The advantage of this is that we ...
20 Νοε 2014 · The advantage of such a wrapper is that you can always fall back onto other functions prior C++17 while always having the same interface: // alternative pre-C++17 version bool parse_int(const std::string& str, int& out, int base = 10) { errno = 0; char* end = nullptr; out = std::strtol(str.data(), str.data() + str.size(), &end, base); return ...
