I have reinstalled MYSYS2 and using MINGW64 terminal:
pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-cmake
pacman -S mingw-w64-x86_64-gdb
pacman -S git
cd /c/users/pvros/
cd dev
git clone https://github.com/fltk/fltk.git
cd fltk
mkdir -p build/Debug
cd build/Debug
cmake -DCMAKE_BUILD_TYPE=Debug -DOPTION_USE_SYSTEM_ZLIB=OFF
../..
ninja
Now gets me a bit further.
cmake -G offered me many more targets, but when I tried
"MinGW Makefiles" got:
$ cmake -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Debug ../..
CMake Error: CMake was unable to find a build program
corresponding to "MinGW Makefiles". CME_PROGRAM is not set.
You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

"C:/Users/pvros/dev/fltk/build/Debug/CMakeFiles/CMakeOutput.log".
You seem to miss `mingw32-make`. Please try this command (output
from my system):
$ mingw32-make --version
GNU Make 4.3
Built for Windows32
...
If it issues "command not found" then that's probably the cause. I
believe you can install it with:
$ pacman -S mingw64/mingw-w64-x86_64-make
which installs the 64-bit version of `mingw32-make`. Or maybe you
need another package, I'm not sure. It's definitely one of the
packages I have installed.
Hint: you can search for a particular tool/package name, e.g. 'make'
with:
$ pacman -Ss make | grep x86_64
There are a lot of different packages with similar names (for
different build scenarios) which makes it so hard to find the
correct packages for your MSYS2 installation. :-(
So I went with the default: Ninja
I now fail at:
$ ninja
[556/582] Generating fast_slow.cxx, fast_slow.h
FAILED: test/fast_slow.cxx test/fast_slow.h
C:/Users/pvros/dev/fltk/build/Debug/test/fast_slow.cxx

C:/Users/pvros/dev/fltk/test/fast_slow.fl"
[560/582] Linking CXX executable bin\test\radio.exe
Where it appears to have stopped.
FWIW, I just tried Ninja on my system:
$ /mingw64/bin/cmake -G Ninja ../..
-DOPTION_USE_SYSTEM_LIBJPEG:BOOL=OFF -D
OPTION_USE_SYSTEM_LIBPNG:BOOL=OFF -D OPTION_USE_SYSTEM_ZLIB:BOOL=OFF
-D CMAKE_EXE_LINKER_FLAGS="-static-libgcc -static-libstdc++"
... and it worked for me, building "native" Windows applications
with one exception (see notes).
Notes:
1. "/mingw64/bin/cmake": I had to use the explicit path (I have both
the MSYS2 and a Windows CMake installed and for an obscure reason
pure `cmake` starts the Windows version).
2. All system image libs (jpeg, png, zlib) are disabled.
3. CMAKE_EXE_LINKER_FLAGS="-static-libgcc -static-libstdc++": make
sure you don't need these DLL's
4. Remaining issue: unfortunately the build (still) depends on
`libwinpthread-1.dll => /mingw64/bin/libwinpthread-1.dll` as
output by `ldd`
Point 4 is something I need to investigate because it makes the
executables depend on this DLL. You can either run the programs from
your MSYS shell or copy the DLL to the binary directory side by side
with the executables if you want to run these programs under pure
Windows.
Yes, I think you're on a good way. Maybe the only thing is to
install the remaining package (see above).
