libffi with Visual Studio 2013 - c++

Question

I need to compile the libffi library to use it in a Visual Studio 2013 project.
I am using libffi 3.0.13, downloaded from their original page
I have been struggling to make it work, following the instructions given in README, or trying to come up with something myself, but ended up failing pretty fast.
I tried:
using the Mingw environment to configure the libffi. But that is done for 'gcc' and 'make'. If I compile with gcc, it probably won't link with VS project correctly (right?). Besides, I don't have make (I would install it gladly, if gcc compilation would suffice)
using the ../configure CC="../msvcc.sh -m64" command as suggested in README, but my mingw does not know what cl is.
Tried providing the full path to cl.exe, but the compiler failed the configure tests. The log shows:
configure:3673: ../msvcc.sh conftest.c >&5
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\cl.exe -MD -nologo -W3 conftest.c
conftest.c
LINK : fatal error LNK1104: cannot open file 'MSVCRT.lib'
Tried using the Visual Studio shell, but then the configure program is unknown

Answer 1

first, forgive my poor english! I solved this problem just now!
find your msvcc.sh
modify it, find this postion:
else
args="$md $args"
echo "$cl $args"
eval "\"$cl\" $args"
result=$?
fi
I add some flags:
else
args="$md $args"
echo "********"
args=" $args -ID:/soft/Microsoft\ Visual\ Studio\ 12.0/VC/include/ -link -LIBPATH:D:/soft/Microsoft\ Visual\ Studio\ 12.0/VC/lib/ -LIBPATH:C:/Program\ Files\ \(x86\)/Microsoft\ SDKs/Windows/v7.1A/Lib/"
echo "********"
echo "$cl $args"
eval "\"$cl\" $args"
result=$?
fi
change "D:/soft/Microsoft\ Visual\ Studio\ 12.0" these things to your path!
in cygwin: ./configure CC=E:/project/3rd_parth/libffi/libffi-3.0.13/msvcc.sh(also change the path)
done!
Hope it is not too late!
