Re: [libvirt] libvirt on mingw: undefined reference to htonl/ntohl



Hi,
On my end I also had built libvirtmod.a, but without a DLL version of this file I don't think it will be loadable as a Python module.
Or is there a way to load or link static libraries somehow in Python?
Brecht

P.S.: I didn't understand your spelling remark.

Hi, Brecht

I can compile and generate .a file on python directory.
Sorry for spelling (I am using Zen-kaku(2byte) character in your name.)

Thanks

Hi, Brecht

I can make .a file(not .dll).
With following instruction.

==1==
Install 
http://www.python.org/ftp/python/2.5.2/python-2.5.2.msi
to /usr/local/(C:\msys\1.0\local)

and copy to include file to /usr/include/python2.5
and copy /usr/local/python.exe pythonw.exe to /usr/local/bin

==2==
Install to /usr/local (C:\msys\1.0\local)
http://ftp.gnome.org/pub/GNOME/binaries/win32/pygobject/2.14/pygobject-2.14.1-1.win32-py2.5.exe

make and make install seems work fine.

Thanks

Hi, Brecht

      
Just out of curiosity, have you done anything with virsh or the DLL you 
have built?
        
Yes

By the way, I am doing to build Python bingings on MinGW.
But it will need to do tomorrow, since many compilation warnings.

Thanks

Hi,
I guesss I had got as far as you did.
To Install Python on Windows you will need to download and install the 
following:
    http://www.python.org/ftp/python/2.5.2/python-2.5.2.msi
    
http://ftp.gnome.org/pub/GNOME/binaries/win32/pygobject/2.14/pygobject-2.14.1-1.win32-py2.5.exe
    
http://ftp.gnome.org/pub/GNOME/binaries/win32/pycairo/1.4/pycairo-1.4.12-1.win32-py2.5.exe
    
http://ftp.gnome.org/pub/GNOME/binaries/win32/pygtk/2.12/pygtk-2.12.1-2.win32-py2.5.exe
Also, don't forget to set some environment variables:
    export PYDIR=/C/Prog/Python25
    export PYTHONHOME=$PYDIR
    export PYTHONPATH=$PYDIR/Lib/site-packages
    export PATH=$MINGWPREFIX:$MINGWPREFIX/bin:$PATH
Just out of curiosity, have you done anything with virsh or the DLL you 
have built?
Regards,
    Brecht

Hi, Bericht

By your suggestion, I am recognizing python bindings are not created(on my configuration).
If you notice me to install python on MinGW, I will try to investigate it.

My posting mail is follows(it does not create python library)
https://www.redhat.com/archives/libvir-list/2008-June/msg00201.html
It creates general library and virsh only.

Thanks

No. Can you tell me where to find it?
I also noticed that I only produced one DLL: libvirt-0.dll.
No Python module DLL was built. Were you able to build this?

Hi,

Did you check my instruction for libvirt on MinGW?

Thanks

Hi,
Some time passed by and I thought I'd have another go at compiling 
libvirt for win32 using MinGW/MSYS again.
I tried to compile libvirt-0.4.3 and I got around most obstacles. Now it 
just seems I am stuck when it is trying to link.
My search on google showed me that I am not the first one to see this issue.
Usually i means -lws2_32 is in the wrong place. However I tried moving 
it around without luck.
Also it doesn't make sense to me that only htonl and ntohl are missing. 
It appears anything else used from the winsock library is found during 
linking.
I feel we're very close to getting libvirt compiled on win32. Or do you 
know if anyone already succeeded?
Regards
    Brecht Sanders
