[Mapserver-users] Re: Mapscript perl

[Joe Bussell]

Greetings Roberto,
    I have taken the liberty of recasting this information request into 
the waters of the group.  I do so in the hope that any useful 
information which would come from this exchange would be known to all.

    It has been some time since I did my cygwin build.  Several things 
have changed since then.  It is my belief, certainly my hope, that the 
terrible hacks that I made to get Perl Mapscript to compile would cease 
to be required as the products mature.  I think that you are on the 
right track with compiling without the modifications to the Makefile 
that I suggested.  It may be the case that you have a working solution.

    Did you migrate the dll that you successfully created to another 
machine?  I ask this because I suspect that the cygwin.dll may be 
missing from the target box.  Cygwin compiles its guts into anything you 
build there.

    Could you provide the results of ldd on the resulting dll?  This 
should clarify where the references are and if there is any dependancy 
that was not apparent (such as to cygwin.dll).

    If anyone knows more about this please let me know.

Cordially,

Joe Bussell
