Hi,

I am trying to use libpopt but I can't link to it using -lpopt to gcc 
because libpopt.a doesn't exist in /lib or /usr/lib.

I have an up-to-date 64 bit installation and I have all of 
libpopt-common, libpopt-devel and libpopt0 installed at the current 
version 1.16.2.  In my /lib and /usr/lib directories I have 
libpopt.dll.a, but no libpopt.a, unlike, for example, libreadline, which 
has libreadline.a and libreadline.dll.a.

I can link successfully using -lpopt.dll however.  I presume, but can't 
seem to find any information, that linking against libThing.a and 
libThing.dll.a, where both are available, gives wither a static or 
dynamic link?

I always used to be able to link against libpopt.a, but I think that was 
always in an older 32bit installation, I may never have tried to build 
this program in the 64-bit environment.

Can anyone give me any pointers please?  Can I generate libpopt.a 
somehow?  Or should it really be there and there is an error in the 
cygwin package?

Cheers,
Trevor
