Which MinGW version to use (source compilation and using library)?

support
#1

I’ve tried several versions and can’t get an example code compiling - stackoverflow post. long list undefined reference to __mingw_free’` either GNU or LLVM MinGW

I tried to compile the source with llvm mingw-w64 but Cmake gave error:

D:\Dev\C\glfw-3.3.3>cmake .

  It fails with the following output:

  CMake will not be able to correctly generate this project.

Please, can you give me a link to an exact version that works?

#2

Same cmake error with GNU mingw

#3

The issue may be that you’re requesting NMake Makefiles instead of MinGW Makefiles.

#4

How to change that? I just did as the building guide said.

#5

I’m not sure how your setup has become configured for nmake but using gcc, however you can get cmake to use the MinGW Makefile generator by using the -G "MinGW Makefiles" option:

cmake -G "MinGW Makefiles" .
