I'm trying to compile a library (dxflib) for use in windows using cygwin.
I'm loosely following the instructions found here: http://www.ribbonsoft.com/doc/dxflib/2.5/reference/dxflib-reference-manual.pdf
I can get it to compile to make a .a library (ie a unix static library), using 'make' but obviously I'm using cygwin because I want to compile a .lib for use in windows.
When I try to use 'MinGW32-make' (or any other derivative I can think of) cygwin claims that it doesn't exist. I've reinstalled all options with mingw or gcc or g++ remotely in their name in cygwin.
Does anybody know how to get it to compile from the makefile to produce a .lib? Thanks.

I'm trying to compile a shared library with cmake to use it further with the "dlfcn" lib in a C program. I am on Windows with Cygwin, but I don't know how to use "dlfcn" with the shared libraries of windows (.dll and .dll.a) and my teammates are using Linux. So I would like to create not .dll and .dll.a libraires but a .so library. I'm a beginner with cmake, is there a possibility to do it or am I obliged to install a Linux VM ?
So, thanks to #Florian, I finally made it. To the ones who want to know how it works, it's quite simple :
Create a new .cmake file :
# this mandatory command will be the one that will make your cross-compiling work
set(CMAKE_SYSTEM_NAME Linux)
# indicate compilers (optional)
set(CMAKE_C_COMPILER gcc)
set(CMAKE_CXX_COMPILER g++)
When calling your cmake command, add an argument like this :
cmake -DCMAKE_TOOLCHAIN_FILE=./myToolChainFile.cmake ..
-mno-cygwin compiler parameter doesn't exist.
I tried to use '-static', but then compiler can't find installed -lpng
You need to cross compile it. Run x86_64-w64-mingw32-gcc, included in package mingw64-x86_64-gcc-g++, in cygwin64 to cross compile a native windows 64bit executable. It is similar if you are in cygwin or to compile a 32bit executable.
However, without cygwin compatibility layer, a program using POSIX APIs cannot be compiled. If your program needs POSIX APIs, you have to compile with cygwin dependency.

I have a project written in gcc - bison -flex on Linux environment. All the project is implemented into a *.so file and is called from python-tkinter graphic surface.
There is a need to run it on windows. However I'd avoid to install all the windows equivalent of gcc - bison -flex programs.
Is it possible to force gcc IN LINUX ENVIRONMENT to compile WINDOWS DLL instead of *.so? It could make life easier to use the same technics as I do now: just do calls from python-tkinter graphic surface.
You can, of course, cross-compile it.
You'll need some packages installed, though.
Your normal project would be able to build if you use the MINGW equivalent of GCC for the target architecture.
Also, take a look at this:
Manual for cross-compiling a C++ application from Linux to Windows?
The linking can be kind of troublesome though, since it could come a time where softlinking fails due to versions. In that case you'll need to create some symbolic links to the correct version.
The output of the compilation process should be with -o DYNAMIC-LIBRARIE-NAME.dll and of course use the -shared flag.
Hope it gives you some pointers..

I'm trying to compile Pyaudio, (a Python module) from source, since I'm using Windows, and only 32-bit binaries are available - I need 64. Following these instructions I downloaded Cygwin, and installed every component, to be safe. Installing Portaudio, another module, is required first.
When I run CFLAGS="-mno-cygwin" LDFLAGS="-mno-cygwin" ./configure, I get the error configure: error: C compiler cannot create executables. See 'config.log' for more details. config.log has an additional line below that message: gcc: The -mno-cygwin flag has been removed; use a mingw-targeted cross-compiler.
This leads me to believe that perhaps Cygwin is using the wrong compiler; the instructions are for using MinGw with Cygwin, but I never specified minigw in the process. I also wonder if there's something in the PyAudio build files that needs to be changed for 64-bit. I know nothing about C, compiling, Cygwin or MinGW, and am new to programming in general. Any ideas? Any other information I can provide?
Current versions of Cygwin gcc do not support -mno-cygwin anymore because it never really worked correctly. Instead, you should use a proper cross-compiler, which is provided by the mingw64-i686-gcc packages, then run ./configure --host=i686-w64-mingw32.
In some cases it is an antivirus that is causing problems.
I had avast and had to disable it.
I am using gcc/g++ to compile c/c++ applications - living on OpenSuSe btw.
Is there any way (some option i guess) so that g++ will produce an executable suitable for windows ?
You can search for a mingw32 package in OpenSuSE (I know there is one for Debian) or install it manually. Then if you have a configure script the command line would be something like this in order to have make use the MinGW cross-compilation toolchain:
./configure --prefix=/usr/local --target=i386-mingw32
mingw.org also has a tutorial on building a cross compiler, don't know if that works.
(As an aside: Some websites point to mirzam.it.vu.nl/mingw containing MinGW RPM packages but it seems like that site is down.)
You'll have to be running g++ on Windows to get a Windows executable out of the other end.
Check out mingw or cygwin.
