RE: Gtk+ 3.0 and MS Windows

["Mikhail Titov" <mlt gmx us>]

Just in case someone is following :-)

I was able to successfully build GTK+ 3.0.6 using MS VC++ 2008 Express using underlying OpenSUSE win32 binaries. I had to play around with nm.exe and lib.exe (MS proprietary tool) to generate missing dot def files as a usage of gcc libraries (.dll.a) resulted in a weird behavior (like import of symbols from improper dll as I reported before).

Gtk-demo.exe runs mostly okay though toolbar icons are not redrawn after menu popup and it dumps sometimes warnings. Tool Palette demo is glitchy in sense of icons. Entry, Icon View, Text Widget demos don't show up at all. Pickers demo fails with " GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser' is not installed"

I don't have much spare time, but I'll try to summarize what should be done to utilize cross-compiled binaries (like from OpenSUSE) to build stuff using MS VC++. I guess it would be substantial time saver not to manually build dependencies under MS Windows.

Here is the python script I used to convert libraries from gcc to MSVC format:

-----------------8<------------------------------
import os,re,sys,shutil
from os.path import join, getsize
from subprocess import Popen, PIPE
os.environ['PATH'] = os.environ['PATH'] + ";C:\\Program Files\\Microsoft Visual Studio 9.0\\Common7\\IDE\\;C:\\Program Files\\Microsoft Visual Studio 9.0\\VC\\bin\\;C:\\MinGW\\bin"
#gendef = "C:\\workspace\\glibmm-2.27.99\\MSVC_Net2008\\gendef\\Win32\\Debug\\gendef.exe"
#    dll = re.sub(".a", "", lib)
#    output = Popen([gendef, d, dll, lib], stdout=PIPE).communicate()[0]

def gen(dll):
    name = re.sub("^lib", "", dll)
    name = re.sub("(?:-\\d).dll", "", name)
#    shutil.copyfile(lib, name + ".lib")
    print("Working on %s\n" % dll)
    output = Popen(["nm", "lib%s.dll.a" % name], stdout=PIPE).communicate()[0]
    d = "%s.def" % name
    with open(d, "wb") as f:
        f.write(b"EXPORTS\n")
        for line in output.split(b"\r\n"):
            if (re.match(b".* T _|.* I __nm", line)): #|.* I __imp
                line = re.sub(b"^.* T _|^.* I __nm__", b"", line) #|^.* I _
                f.write(line + b"\n")
        f.write(str.encode("LIBRARY %s\n" % dll))
    p = Popen(["lib", "/def:%s" % d]) #, shell = True)

root = "C:\\workspace\\gtk\\usr\\i686-w64-mingw32\\sys-root\\mingw"
os.chdir(root + "\\lib")
for root, dirs, files in os.walk(root + "\\bin"):
    for name in files:
        if (re.search(".dll", name)):
            print("Processing: %s\n" % name)
            gen(name)


#gen("libatk-1.0-0.dll")
#  glibmm-2.4.def libglibmm-2.4-1.dll libglibmm-2.4.dll.a
# dumpbin /SYMBOLS /OUT:dumpbin.out libglibmm-2.4.dll.a

2) It turned out that glibconfig.h from OpenSUSE is not MSVC friendly.
Perhaps it redefines something important. I took that from gnome's ftp win32 binary. From quick look at the diff output, there is not much difference other than MS specifics in #ifdef blocks. Now at least gdk-win32 compiles.
