5490 :: Using different compilers on windows

• Lecale (orginal) [2019-11-12T10:42:40+01:00] view original

  Is there any guide which shows you how to change the compiler you're using on windows, i.e. how to install a different one to Mingw?

  Background: I ask because I have gotten stuck on an exception trying to load bitmap files with the stb_image library. It was suggested that I use a different compiler to see if it resolves anything. I installed nim with choosenim stable. I have thus Mingw as the default. I've no idea how to go about switching.

  You can change C/C++ backend compiler with --cc option. https://nim-lang.org/docs/nimc.html#compiler-selection

  For example, --cc:vcc use cl.exe in MS Visual Studio. --cc:clang use clang.

  If you want to use different gcc, add following option to your cfg file.

  
  gcc.exe = "c:\\path\\to\\your\\gcc.exe"
  Run

  Thanks, Clang is for MacOsX I assume, so I am going to try this compiler https://code.visualstudio.com/docs/cpp/config-msvc and see if it makes the slightest bit of difference to allowing me to introduce nim to work

  @Lecale, Either GCC or Clang work fine on Windows by installing them through MSYS2. I believe Nim has also been tested to work with the msvc compiler, but I have never used it myself, and I'm on Windows.

  I currently use Nim to program on Windows and leave 3 different compilers to use: MinGW (gcc), LLVM (clang) and TinyCC (tcc).

  To use them is simple, type at the command line to compile the source code nim: nim c --cc:<gcc|clang|tcc> nimsource.nim

  However, first you need to enter some settings in config/nim.cfg:

  @if windows:
    gcc.path = r"D:/mingw64/bin"
    tcc.path = r"D:/tcc64"
    clang.path = r"D:/LLVM64/bin"
  @end
  Run

  Nowadays I don't use Microsoft's Visual C ++/Visual Studio (vcc), but to use it just open the "Native Tools Command Prompt for VS 2019" and compile nim source code with: nim c --cc:vcc nimsource.nim
