无法在 Mingw 上进行 fltk

Question

我正在尝试在 Windows10 上以 Mingw-32 位安装 fltk。 我从here 下载了fltk-1.3.5，解压缩，cd 到文件夹并运行命令make 来构建它。但它给了我以下错误：

$ make

Mingw-64 位出现类似错误。

问题出在哪里，如何解决？

编辑：我尝试了@jacob 在他的回答中给出的方法，但出现以下错误：

$ cmake -G "MinGW Makefiles" -D CMAKE_MAKE_PROGRAM=mingw32-make ..
CMake Error: Could not create named generator MinGW Makefiles

Generators
* Unix Makefiles               = Generates standard UNIX makefiles.

Answer 1

我能够在 MSYS2 中使用 MinGW-w64（64 位）编译 Fltk 1.3.5，没有任何警告。我是这样处理的：

tar xvf fltk-1.3.5-source.tar.bz2
cd fltk-1.3.5
mkdir build
cd build
cmake -G "MinGW Makefiles" -D CMAKE_MAKE_PROGRAM=mingw32-make ..
mingw32-make

除了编译器本身，关键包是mingw64/mingw-w64-x86_64-cmake 和mingw64/mingw-w64-x86_64-make。
