How to compile under Win 64-Bit?

Question

C++ / C#

Good day to all. I need this library in a DLL for 64 bit Windows.
sourceforge.net/p/libdmtx/wiki/Home
Please attribute it with understanding, I have never compiled anything, I have no experience at all. I read the manuals, I did not understand anything. I only realized that I need to install Cygwin first, which is what I'm doing now. Could someone who understands in the form of a short list with points describe what to do? What would be completely for the "wooden"?
Thanks in advance

Answer 1

1. Install Mingw
2. Open console
3. Go to source folder
4. Act on readme,mingw

Answer 2

There is a README.mingw file in the source folder:
Install MinGW and MSYS
To install libdmtx, download and extract the libdmtx source to your MSYS folder. By default, it is named C:\msys\1.0.
Open an MSYS shell and run the following (type in console and press enter):
$ ./configure
$ make
$ sudo make install
Go to the .libs folder:
$ cd .libs
$ ls
You will see this output
libdmtx.a libdmtx.la libdmtx.lai libdmtx_la-dmtx.o Finally
run
$ gcc -shared -o dmtx.dll libdmtx_la-dmtx.o -Wl,--out-implib,libdmtx.a
You should now have a working dmtx.dll in your .libs folder.
