Won't that fail to link? (ld finds the .dll not the static archive?)

No, it won't.  Let's consider each case, under the assumption that 
/usr/include/gettext.h is the cygwin-modified, dll-supporting version, 
and /usr/share/gettext/intl/gettext.h is the "official" version.

1) You want to build project "foo" which depends on gettext, and you do 
NOT specify --with-included-gettext (or foo doesn't include an embedded 
copy of the gettext source code).  Then, /usr/include/gettext.h is used, 
and /usr/lib/libintl.dll.a is used.  Since dllimport is the default in 
/usr/include/gettext.h, everything is fine.

1a) You want to build project "foo" which depends on gettext, and you do 
NOT specify --with-included-gettext (or foo doesn't include an embedded 
copy of the gettext source code). BUT, you want to link statically. 
Well, then again, /usr/include/gettext.h is used, but you must specify 
-DGETTEXT_STATIC.  Also, you must specify -static when linking, and then 
/usr/lib/libintl.a will be used (these additional flag requirements are 
"normal" for statically linking system libraries on cygwin)

2) You want to build project "foo" which depends on gettext, and you 
specify --with-included-gettext (and "foo" contains an embedded copy of 
the gettext source code).  Well, configure will set things up so that 
foo/intl is in the -I include path, and in the -L libsearch path before 
the system directories.  Since gettext builds as a static lib OOB, 
foo/intl/libintl.a will build okay, and will get used during the link 
process (ld searches the -L path IN ORDER, checking each directory for 
all possible library names -- libintl.dll.a, libintl.a, etc -- before 
moving to the next directory in the path.  Since foo/intl will precede 
/usr/lib in this configuration, foo/intl/libintl.a will be found before 
/usr/lib/libintl.dll.a).  Okay, so /foo/intl/gettext.h is used during 
compilation, and foo/intl/libintl.a is used during linking -- everything 
is fine.

Note that in cases 1) and 2), /usr/share/gettext/intl/gettext.h isn't 
used.  So it doesn't matter if that file is the cygwin-ized version, the 
official version, or my mother's recipe for broccoli quiche.

3) You want to gettextize a package -- say, "bar".  Well, gettextize 
ought to work the same on every platform.  So, since gettextizing uses 
the gettext.h in /usr/share/gettext/intl/, then that file should match 
the "official" version.  This will create a "bar" package identical to 
the one that would be created if it were gettextized on linux.  And as 
explained in 2), that gettextized "bar" package will build just fine.

Did I miss anything?

This is a good question, but it should be on list.  I've redirected this 
email to the list.  See below for commentary.

Well, the gettext.h created by gettextize is made as a copy of a special 
gettext.h stored in /usr/share/gettext/intl/.  During my build process 
for cygwin, the /usr/share/gettext/intl/gettext.h file is created 
identical to the system gettext.h in /usr/include.  So, if the system 
file is different from some baseline, then the created file will also be 
different.

It was necessary to modify gettext.h on cygwin to support using the 
braindead windows shared library format (DLLs).  Functions and variables 
must be declared with special compile-time directives 
(__declspec(dllimport), __declspec(dllexport)) -- thus, the headers must 
be modified.

Now, I have corresponded with the "real" gettext people about this. 
Their response is that these changes are just too damn ugly to 
incorporate -- and there MAY be upcoming changes to GCC and binutils so 
that cygwin no longer requires this uglification.  Therefore, those guys 
are taking a wait-and-see approach.  We all hope that the uglification 
goes away at some point.

Nothing.

If you merely want to gettextize a package that will be built on another 
platform, or will be built on cygwin ALWAYS using the 
--with-included-gettext (that is, you'll never use the cygwin system 
libintl.a with your package), then just

copy the "linux" or "official" gettext.h into /usr/share/gettext/intl on 
your cygwin system.  In fact, that may not be a bad idea in ALL cases, 
because if somebody builds your package on cygwin and DOESN't specify 
--with-included-gettext, then the build will use the 
/usr/include/gettext.h and /usr/lib/libintl.a -- so no problems: your 
"official" gettextized gettext.h won't even get used in that case.

Hmmm...perhaps the cygwin gettext package should put the official 
gettext.h into /usr/share/gettext/intl, and only use the modified, 
DLL-supporting gettext.h for /usr/include...

I think your conclusion is appealing. As I see it the gettext package
should be regarded as a package with two different purposes.

1. The purpose of providing the gettext library and directories on a
   system where it is installed.
2. The purpose of providing every package internationalized with GNU
   gettext with the necessary files consistantly and identically.

My observation is that in this case is that the purpose 1 on a
cygwin-system has infected the purpose 2.

I think the best thing would be if the gettextize command include
non-modified files i.e. directly from the gettext distribution
(exactly as the gettextize command would do on all other systems).

If there are problems getting the purpose 1 right on a system, like
the special DLL-requirements you are talking about, then that would
perhaps complicated purpose 1 but that should never modify purpose 2.

RE: Confused by gettext on cygwin

[Linus Tolke]

Hello Chuck!

Thanks for taking this further. I now succeeded in building my project i.e.
the "make" and "make dist" works. I can even unpack the distribution and
build.

I am still not satisfied though. ;-)

Here is the new and more sofisticated problem.

1. I build my project (make)
2. I build the distribution of my project (make dist)
3. I move the distribution (file tty-client-0.13.alfa.7.tar.gz) to a Solaris
2.7 system.
4. I unpack and run configure on the Solaris 2.7 system.
5. When I run make on the Solaris system it fails in the intl directory.

I interpret this to mean that the version of gettext provided by cygwin is
not as portable as it should be. Remember that this worked before I moved my
development environment to cygwin/autoconf-2.

Here is the error message that the compiler (linker) gives me:
make[2]: Leaving directory
`/tmp/linus_tty-client/tty-client-0.13.alfa.7/librari
es'

Remember, the (now) current version of gettext for cygwin is only 
*partially* migrated over to libtool.  It looks as tho the parts that 
*aren't* are causing a problem on other platforms.  Therefore, the 
"full" correction to this problem will probably have to wait until:

a) we're happy with the current cygwin/libtool port
b) we get the nifty libtool changes pushed into the REAL libtool
c) we ensure that the REAL libtool (which includes our changes) works 
okay on cygwin
d) I *fully* re-libtoolize gettext using the new (REAL) libtool
e) We push the re-libtoolized version to the upstream gettext folks.

THEN, your problems should go away -- but as you can see, it'll be a 
long process.  I'm sorry, but shared libs on windows just plain suck.
