Which compiler am i using

I started using CodeBlocks IDE but just out of curiosity wanted to know which compiler is my program using as it can be 4. Is there any simple command which i can run in my cpp progam and check which compiler my IDE is using? According to the Codeblocks FAQ :. As a matter of fact it largely depends on the used compiler plugin. Code::Blocks is a very generic IDE that can use many compilers. You can even have different compilers for every project.

In the window it brings up make sure you have the "Global compiler settings" icon selected from the list on the left. Change to the "Toolchain executables" page from which you can get the exact path to the compiler executable that your project is using by making sure the "Selected compiler" drop down box at the top of the screen matches the one for your project".

The other way to get that information is to build your project, then switch to the "Build log". The command line should at least have the compiler executable as part of the filename it shows.

At this point it becomes compiler specific to find out what version you are using. For example, if it is GCC or a port then you can run:. If you want to do it from your compiler although technically it will be the preprocessor you will need to know the above information to know what your compiler is, as you need to know the preprocessor macros to check for, which are compiler dependant.

So you are probably OK to use the method Ben Voigt describes. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

If all of the currently installed compilers are insufficient, the easiest course of action is to submit a request to your system administrator to install an updated compiler. The updated compiler need not be installed as the default compiler for the system. Installing as a module or in a non-default directory is also acceptable for use with Rosetta. NOTE: When submitting the request, be sure to mention the issue regarding standard library support, particularly if they are installing an updated version of Clang or ICC.

Installation proceedures may need to be adjusted such that the appropriately updated standard library is also installed. Rosetta does not require that the compiler be installed in a central location. It is perfectly acceptable to install a compiler into your home directory. Also, once the compiler is installed on one user's directory, other users with access to that directory can also use it.

This way not every member of a lab needs to install the compiler. Clang provides pre-compiled binaries of it's compiler for certain systems. If you cannot or do not want to install a newer compiler on a system, there is always the possibility of compiling Rosetta statically on another similar machine, and then copy the compiled programs and database to the new computer.

Your compiler may or may not be able to locate the associated standard library. Sign in to comment. Unable to complete the action because of changes made to the page.

To run the build task defined in tasks. When the task starts, you should see the Integrated Terminal panel appear below the source code editor. After the task completes, the terminal shows output from the compiler that indicates whether the build succeeded or failed. If the build fails due to not finding cl.

Run ls and you should now see the executable helloworld. Note : You might need to press Enter a couple of times initially to see the PowerShell prompt in the terminal. This issue should be fixed in a future release of Windows. You can modify your tasks. This will build all. Next, you'll create a launch. You'll then see a dropdown for various predefined debugging configurations.

VS Code creates a launch. The program setting specifies the program you want to debug. Change the stopAtEntry value to true to cause the debugger to stop on the main method when you start debugging. The Integrated Terminal appears at the bottom of the source code editor.

In the Debug Output tab, you see output that indicates the debugger is up and running. The editor highlights the first statement in the main method. The Run view on the left shows debugging information. You'll see an example later in the tutorial. At the top of the code editor, a debugging control panel appears.

You can move this around the screen by grabbing the dots on the left side.
