Clang on Windows: how to disable the default MSVC compatibility?
To disable the default MSVC (Microsoft Visual C++) compatibility in Clang on Windows, you can use the -fno-ms-compatibility
flag. This flag instructs Clang to disable compatibility with MSVC-specific language extensions and behaviors. Here's how you can use it:
Install Clang: Download and install the Clang compiler for Windows from the LLVM official website (https://llvm.org/builds/). Make sure to select the appropriate version for your system.
Open a terminal: Open a command prompt or terminal where you have Clang installed and can access the
clang
command.Disable MSVC compatibility: When compiling your code with Clang, use the
-fno-ms-compatibility
flag to disable MSVC compatibility. For example:shellclang -fno-ms-compatibility myfile.cpp -o myoutput.exe
Replace
myfile.cpp
with the path to your C++ source file andmyoutput.exe
with the desired output file name.This flag tells Clang to disable MSVC-specific language extensions, so the resulting binary is based purely on the standard C++ language without any MSVC compatibility.
By using the -fno-ms-compatibility
flag, you can ensure that Clang on Windows does not enable MSVC compatibility by default and sticks to standard C++ behavior. Keep in mind that this may cause incompatibilities with code that relies on MSVC-specific language extensions or behaviors.
Please note that the specific commands and configurations may vary depending on your installation and project setup. Refer to the Clang documentation for more information on available flags and options.
