By the way how do you manage to daily build Hamlib on Windows ? Compile 
farm ?

Ah good, very good ... I did my best to use the latest 1.2 version in 
MXE, but even with all possible configure options, no way to build with 
the existing MXE-provided ltdl lib. With some changes it sorts of work. 
With hamlib3 I could make it use its own libltdl but not the MXE one.

Funny that it was not seen before :)

So which direction do you suggest ?
* Use hamlib3 ? It has to be available from a stable URL. 
http://n0nb.users.sourceforge.net/hamlib-3.0~git-a16dd47-20130426.tar.gz ?

* Or fix hamlib1.2 : configure.ac, maybe add macros/ltdl.m4, maybe fix 
Makefile.am and src/Makefile.am ?


Thanks

PS: FYI, the MXE setup is simple. In mxe/index.html, just add these lines:


     <tr>
         <td id="hamlib-package">hamlib</td>
         <td id="hamlib-version">1.2.15.3</td>
         <td id="hamlib-website"><a 
href="http://hamlib.org/">Hamlib</a></td>
     </tr>


... and in the directory mxe/src, create the new file hamlib.mk :

# This file is part of MXE.
# See index.html for further information.
