Not able to make fltk on Mingw

问题

I am trying to install fltk in Mingw-32 bit on Windows10. I download fltk-1.3.5 from here, unzipped it, cd to folder and run command make to build it. But it gives me following error:

$ make
=== making jpeg ===

Similar error occurs on Mingw-64 bit.

Where is the problem and how can it be solved?

Edit: I tried method given by @jacob in his answer but got following error:

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

回答1:

I was able to compile Fltk 1.3.5 with MinGW-w64 (64 bit) in MSYS2, without a single warning. I proceeded like this:

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

Aside from the compiler itself, the key packages were mingw64/mingw-w64-x86_64-cmake and mingw64/mingw-w64-x86_64-make.
