Should I use MSVC or MinGW?

Should I use MSVC or MinGW?

Results: MSVC is doing the compilation job significantly faster than MinGW-w64. The DLL sizes are comparable, if optimization is set to “-O2” for MinGW-w64, with “-O3” the DLLs from MinGW-w64 are larger. Binary files compiled with MinGW-w64 are performing significantly better than those compiled with MSVC.

What is MSVC and MinGW?

Basically, MinGW is a port of Linux (GNU, actually) tools for Windows, which happen to include a port of GCC (the actual compiler). MSVC, on the other hand, is a Windows native tool chain and runtime for building C/C++ executables.

Where do I put DLL files in MinGW?

Typically DLLs go in a folder named “ bin ”, and import libraries go in a folder named “ lib ”, for example “ C:\Program Files\Add\bin\ ” and “ C:\Program Files\Add\lib\ ”.

Should I use GCC or MSVC?

GCC is for people who don’t mind spending 4 hours at the computer making it work properly. MSVC is for those who don’t care about C and want it to install without any pokin’ around.

What is MSVC compiler?

Microsoft Visual C++ (MSVC) is a compiler for the C, C++ and C++/CX programming languages by Microsoft. MSVC is proprietary software; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms.

Is Clang faster than MSVC?

32-bit MSVC. When I switched to both clang and MSVC 64-bit versions, I see MSVC is faster than clang by about 1.5X. On 32-bit toolsets, I saw that MSVC is 2X slower than Clang. This, however, is totally believable because MSVC performance is tracked mostly on the 64-bit toolset.

Is clang faster than MSVC?

How do I create a DLL file?

Create the DLL project

  1. On the menu bar, choose File > New > Project to open the Create a New Project dialog box.
  2. At the top of the dialog, set Language to C++, set Platform to Windows, and set Project type to Library.
  3. From the filtered list of project types, select Dynamic-link Library (DLL), and then choose Next.

What does __ Declspec Dllexport do?

__declspec(dllexport) adds the export directive to the object file so you do not need to use a . def file. This convenience is most apparent when trying to export decorated C++ function names.

Is MSVC slower than GCC?

Compile the attached code which uses Eigen in VS and with clang/gcc, and see how the MSVC code is 1.5-2x slower than the code produced by MSVC.

Is MSVC compiler free?

MSVC is a closed, proprietary C/C++ compiler developed and distributed by Microsoft; there is no real good reason justifying to use this proprietary compiler when a wonderful genuine free sw standard compiler is available on Windows as well [MinGW, MinGW].
