Re: [igraph] Cygwin -> Windows compilation - Current summary.

[Mark McClure]

Well, I've been trying quite hard for a couple of days now to
compile an igraph based program in Cygwin that will run on
Windows.  My ultimate objective is to create Mathematica
interface to igraph but, if my Windows based colleagues can't
use it, there's really no point.

Incidentally, I've been doing this in pure Cygwin - I have no
MingGW.  Should I?

At any rate, here's as close as I've got from the top.
First, cd to src/f2c and edit etime_.c and add:
  #undef USE_CLOCK
  #define USE_CLOCK
just before the #ifndef USE_CLOCK line.  According to Tamas,
this fixes a compilation error since the MinGW runtime doesn't
have sys/times.h. Then run the following commands:
  ./configure --disable-graphml --disable-gmp CFLAGS=-mno-cygwin
  CXXFLAGS=-mno-cygwin
  make
  make install

The -mno-cygwin flag should build the library without Cygwin
dependencies.  Then,  we should be able to compile a program with:
 gcc -mno-cygwin name.c -I/usr/local/include/igraph -L/usr/locallib
-ligraph -o name  

Unfortunately, the resulting program still doesn't run.  We can
see why by examining the DLL dependencies as follows:
  $ objdump -p automorph.exe | grep "DLL Name"
        DLL Name: cygigraph-0.dll
        DLL Name: KERNEL32.dll
        DLL Name: msvcrt.dll

The cygigraph-0.dll dependency is still there.

All for now,
Mark
