Title: g++.exe what -std=c++ <what version>
Post by: jmClifford on April 22, 2024, 05:08:13 pm

Hi. I understand that I have installed a compiler package in a folder MinGW.
If I do not specify in CB what to use, then how can I determine what has been used
(wrt C++ standard) ??

A sample of the built log follows;

Quote

-------------- Clean: Debug in ThreadNames (compiler: GNU GCC Compiler)---------------

Cleaned "ThreadNames - Debug"

-------------- Build: Debug in ThreadNames (compiler: GNU GCC Compiler)---------------

g++.exe -Wall -fexceptions -g -IC:\WxWidgetsSetup\include -IC:\WxWidgetsSetup\lib\gcc_dll -c C:\u\CodeBlock_C++\EasyLoggingpp_ThreadNames\ThreadNames\easylogging++.cc -o obj\Debug\easylogging++.o
g++.exe -Wall -fexceptions -g -IC:\WxWidgetsSetup\include -IC:\WxWidgetsSetup\lib\gcc_dll -c C:\u\CodeBlock_C++\EasyLoggingpp_ThreadNames\ThreadNames\main.cpp -o obj\Debug\main.o
g++.exe  -o bin\Debug\ThreadNames.exe obj\Debug\easylogging++.o obj\Debug\main.o   C:\WxWidgetsSetup\lib\gcc_dll\libwxmsw32ud.a C:\WxWidgetsSetup\lib\gcc_dll\libwxmsw32u.a
C:\u\CodeBlock_C++\EasyLoggingpp_ThreadNames\ThreadNames\easylogging++.cc: In member function 'el::Logger* el::base::RegisteredLoggers::get(const std::string&, bool)':

What ever is the default for the Compiler version installed!

Learn about the compiler you installed and the use a web search tool to find the default standard for C and C++.

You can print the __cplusplus macro, see this link (https://en.cppreference.com/w/cpp/preprocessor/replace#Predefined_macros) for more information.

I followed and solved the problem. Thank you very much for the information.

You do specify the C++ standard in project - build options (Have g++ follow the C++... options), it's the easiest way to know what C++ version is used.
