Compiling MLDonkey for Windows

MLDonkey is a nifty program that helps you share files with other people. MLDonkey works on Linux, but the Windows version I downloaded didn't work on my computer running Windows XP. So I compiled MLDonkey using Cygwin's mingw64-i686-gcc-* compiler toolchain. Here I show how I did it. Part of the information below is taken from the MLDonkey Windows guide.

1. Cygwin Setup
   
   First, install Cygwin using the Cygwin installer(setup.exe). I set the Root directory to C:\Cygwin and chose to install the following packages in addition to base packages.
   
   
   
   
   
   • bison
     
   
   
   • gettext-devel
     
   
   
   • libtool
     
   
   
   • make
     
   
   
   • mingw64-i686-binutils
     
   
   
   • mingw64-i686-gcc-core
     
   
   
   • mingw64-i686-gcc-fortran
     
   
   
   • mingw64-i686-gcc-g++
     
   
   
   • patch
     
   
   
   • pkg-config
     
   
   
   
   

Open the file C:\Cygwin\etc\fstab in a text editor and append the following line.




/usr/i686-w64-mingw32/sys-root/mingw /mingw none bind





Set the HOME variable.





Start the Cygwin terminal and type the following commands to set up Cygwin for Windows compilation.





cp /usr/bin/i686-w64-mingw32-g++.exe /usr/i686-w64-mingw32/bin/g++.exe
cp /usr/bin/i686-w64-mingw32-gcc.exe /usr/i686-w64-mingw32/bin/gcc.exe
cp /usr/bin/i686-w64-mingw32-cpp.exe /usr/i686-w64-mingw32/bin/cpp.exe
export PATH=/mingw/bin:/usr/i686-w64-mingw32/bin:/usr/local/bin:/usr/bin:/usr/lib/gcc/i686-w64-mingw32/4.5.3
export CC=/usr/bin/i686-w64-mingw32-gcc.exe
export PKG_CONFIG_PATH=/mingw/lib/pkgconfig



2. Compile zlib and bzip2
   
   Download the zlib source (zlib-1.2.7.tar.gz) and unpack it.
   
   
   

   tar xzvf zlib-1.2.7.tar.gz
   cd zlib-1.2.7

   
   Compile and install zlib.
   
   
   

   make -f win32/Makefile.gcc
   cp -iv zlib1.dll /mingw/bin
   cp -iv zconf.h zlib.h /mingw/include
   cp -iv libz.a /mingw/lib
   cp -iv libz.dll.a /mingw/lib

   
   Now download bzip2 source from bzip2.org and unpack it.
   
   
   

   tar xzvf bzip2-1.0.6.tar.gz
   cd bzip2-1.0.6

   
   Change line 78 of bzlib.h to read:
   
   
   

   #if defined(_WIN32) && !defined(__MINGW32__)

   
   Compile and install bzip2.
   
   
   

   make
   cp bzlib.h /mingw/include/
   cp libbz2.a /mingw/lib

   
   



3. libiconv
   
   Download and compile libiconv:
   
   
   

   tar xzvf libiconv-1.14.tar.gz
   cd libiconv-1.14
   ./configure --build=i686-w64-mingw32 --prefix=/mingw --enable-static
   make
   make install

   
   



4. JPEG, PNG & Freetype
   
   Compile JPEG, libPNG and Freetype in the following way:
   
   
   

   ./configure --build=i686-w64-mingw32 --prefix=/mingw
   make
   make install

   
   
   
5. GD Graphics Library
   
   Now get the libgd source, unpack and configure:
   
   
   

   ./configure --build=i686-w64-mingw32 --prefix=/mingw LIBS="-lbz2 -ljpeg -lws2_32 -liconv"

   
   Once Makefile is generated, change line 233 to read:
   
   
   

   DEFS = -DHAVE_CONFIG_H -DBGDWIN32

   
   Also fix gd.h near line 25:
   
   
   

   --- ./gd.h      Sat Oct 30 12:54:58 2004
   +++ ./gd.h Sun Jan 05 17:56:09 2006

   +#define BGD_DECLARE(rt) extern rt _stdcall
    #else
    #ifdef BGDWIN32
    #define BGD_DECLARE(rt) __declspec(dllexport) rt __stdcall

   
   Then, build and install gdlib:
   
   
   

   make install

   
   
   

   To create a DLL file called libgd-2.dll, run the following commands:

   
   
   

   mkdir /tmp/gdlib
   cd /tmp/gdlib
   ar x /mingw/lib/libgd.a
   gcc -shared -o /mingw/bin/libgd-2.dll -Wl,--out-implib,libgd.dll.a *.o -L/mingw/lib -lz -lbz2 -ljpeg -lpng -liconv -lfreetype

   
   
   



6. wget
   
   Build wget as shown in this post. If you don't want to compile wget yourself, get the executable (wget.exe) somewhere, and put it in the same folder as mlnet.exe later.
   
   
7. regex and libmagic
   

   Download regex-0.12.tar.gz and compile regex as required by libmagic.

   
   

   gcc -DSTDC_HEADERS -DHAVE_STRING_H=1 -I. -c regex.c
   ar ru libregex.a regex.o
   cp -iv libregex.a /mingw/lib
   cp -iv libregex.a /mingw/lib/libgnurx.a
   cp -iv regex.h /mingw/include

   
   

   Get the source tarball of open-source file command. Configure as follows:

   
   

   ./configure --build=i686-w64-mingw32 --prefix=/mingw

   
   

   Open config.h and add the following lines:

   
   

   #define WIN32 1
   #define MAGIC "magic"

   
   

   Then compile:

   
   

   make && make install

   
   
   
8. OCaml
   
   You need flexdll (flexdll-0.27.zip) to build OCaml. Extract it to /mingw/bin. Then, download the latest OCaml source (3.12.1). Patch ocaml with this Unicode patch.
   
   
   

   tar xzvf ocaml-3.12.1.tar.gz
   cd ocaml-3.12.1
   patch -p1 -l < ../ocaml-3.12.1-unicode.patch

   
   
   

   In the config subfolder, copy Makefile.mingw to Makefile.

   
   
   

   cp config/m-nt.h config/m.h 
   cp config/s-nt.h config/s.h 
   cp config/Makefile.mingw config/Makefile 

   
   
   Begin compiling OCaml.
   
   
   

   make -f Makefile.nt world
   make -f Makefile.nt opt
   make -f Makefile.nt opt.opt
   make -f Makefile.nt install

   
   
   Set up OCaml environment variables:
   
   
   

   export CAMLLIB=/mingw/lib
   export OCAMLLIB=/mingw/lib
   export CAMLP4LIB=/mingw/lib/camlp4

   
   



9. Build MLDonkey
   
   Get the MLDonkey source, then unpack and configure it.
   
   
   

   tar xjvf mldonkey-3.1.0.tar.bz2
   cd mldonkey-3.1.0
   ./configure --build=i686-w64-mingw32 --prefix=/mingw --disable-fasttrack

   
   
   

   To link with the static GD library, append -DNONDLL to the CPPFLAG line of config/Makefile.config

   
   
   

   CPPFLAGS=-I/mingw/include -DNONDLL

   
   
   Start compilation.
   
   
   

   export OCAML_SRC=~/ocaml-3.12.1
   cp -iv /mingw/lib/stublibs/dllunix.dll .
   make depend
   make mlnet.static 
   strip mlnet.static 
   mv mlnet.static mlnet.exe

   
   If the final linking stage fails, here is the command I used to produce mlnet.exe:
   
   
   

   g++ -g0 -O3 -o mlnet.exe -Wl,--subsystem,windows -L/lib/gcc/i686-w64-mingw32/4.5.3 -L/mingw/lib /tmp/camlstartup00193d.s build/flexdll_mingw.o /mingw/lib/std_exit.o src/daemon/common/commonMain.o build/driver.a build/core.a build/client.a build/common.a build/magic.a build/bitstring.a build/cdk.a build/extlib.a /mingw/lib/nums.a /mingw/lib/str.a /mingw/lib/unix.a /mingw/lib/bigarray.a /mingw/lib/stdlib.a src/utils/cdk/gdstubs.o src/networks/direct_connect/che3_c.o src/utils/lib/CryptoPP.o src/utils/lib/CryptoPP_stubs.o src/utils/net/upnp_stubs.o src/daemon/common/commonHasher_c.o src/utils/lib/magiclib_stub.o src/utils/bitstring/bitstring_c.o src/utils/cdk/zlibstubs.o src/utils/cdk/heap_c.o src/config/mingw/os_stubs_c.o src/utils/lib/fst_hash.o src/utils/lib/md4_comp.o src/utils/lib/md4_c.o src/utils/lib/charsetstubs.o src/utils/lib/md5_c.o src/utils/lib/sha1_c.o src/utils/lib/tiger.o src/utils/lib/stubs_c.o -lnums -lcamlstr -lunix -lbigarray -lgdi32 -luser32 -ladvapi32 -limm32 -lshell32 -lole32 resfile.o -lpthread -lmagic -lgd -ljpeg -lfreetype -lpng -lz -lbz2 -lws2_32 -lshlwapi /mingw/lib/libasmrun.a /mingw/lib/libcharset.dll.a /mingw/lib/libiconv.dll.a

   
   
   Optonally, compress the executable with upx.
   
   

   upx --best --strip-relocs=0 mlnet.exe

To build wget.exe with MinGW

wget is a useful command-line downloader. To build wget for the Windows platform, first install MinGW. Then, compile zlib, openssl and wget in that order. To compile zlib:

make -f win32/Makefile.gcc
cp -iv zlib1.dll /mingw/bin
cp -iv zconf.h zlib.h /mingw/include
cp -iv libz.a /mingw/lib
cp -iv libz.dll.a /mingw/lib

To compile openssl:

./Configure -DHAVE_STRUCT_TIMESPEC -DPTW32_STATIC_LIB -L/mingw/lib -lz -lpthreadGC2 -lws2_32 --prefix=/mingw threads zlib mingw
make
make test
make install

Now, build wget

./configure --prefix=/mingw --enable-threads=win32 --disable-nls --with-ssl=openssl
make
make install
