GPGME

I have been looking at configure.ac for the GPGME package, trying to find out what to do to enable it to build easily on cygwin systems.

Not being an expert with GNU build tools I can only ask what I hope are good questions.

configure.ac has no references to cygwin in it, but it does in line #128 or so have

*-mingw32*) in a case statement.

Shouldn't there also be a

*-*-cygwin*)

Though cygwin does not use dos-ish pathnames, shouldn't it have the follwing setting??

have_w32_system=yes

I don't know if this is used for creating dlls or not?

or if
GPG_DEFAULT='/usr/local/bin/gpg.exe' would be needed or

if the below is relevant or not.
# XXX Assuan is not supported in this configuration.
#GPGSM_DEFAULT='c:\\gnupg\\gpgsm.exe'
#component_system='COM+'

Please take a look at configure.ac and add a case for *-*-cygwin* and
set the appropriate flags to enable w32 dll libraries for gpgme to be built.

Regards,
Darel Henman

gpgme [In reply to]

After fiddling with configure.ac and providing a LDFLAGS=... I have been able to build gpgme up to the following error. I did a "find grep ... " for the undefined reference to "_assuan_set_assuan_err_source", but it only appears in the version.c source
file as a reference.

What am I missing?

Definitely not. Cygwin is a Unix emulation and as such it is very
different from the W32 API.

It is used for all kind of stuff. It is actually an alias for _WIN32,
a name some folks don't like to use in connection with Free Software ;-)

If it does not work like a basic Unix system, something would wrong
with Cygwin. Note, that you need to use aCygwin build of gpg.exe
wiith a Cygwin build pf gpgme - you can't mix them.

Shalom-Salam,
