Re: _imp__gettext undefined when linking recode, configure

[Charles Wilson <cwilson at ece dot gatech dot edu>]

Here's the problem: for whatever reason, --with-included-gettext means
"link explicitly to a custom built gettext library, but just use the
normal -I path when #including header files."

This means you get the system headers (which declare
__declspec(dllimport) gettext_symbols ---> "__imp_gettext_symbol")  but
link to the custom library which only provides "__gettext_symbol".

--without-included-gettext means you get the system headers AND the
system library, which works.  IMO, this is a bug in the
autoconfiguration of recode (and in dozens of other packages).

It's on my todo list to convert the cygwin gettext package into a
new-style, auto-import DLL, which will make the system headers identical
to the "normal" headers, and alleviate this problem.  for now, just use
--without-included-gettext.
