Hi there,
I tried it on Solaris 2.9, gcc-3.3 (sunfreeware) and make-3.80
(sunfreeware) and got a lot of these warnings.
steps were
./configure
make
make check also generates the errors and fails:
[...snip..]
lib/expat.h:985: warning: `cdecl' attribute directive ignored
/bin/bash ./libtool --silent --mode=link gcc -g -O2 -Wall -
Wmissing-prototypes -Wstrict-prototypes -fexceptions -

tests/runtests
ld.so.1: runtests: fatal: libexpat.so.0: open failed: No such
file or directory
make: *** [check] Killed
So I tried installing it via make install and then do another
make check and that seems to work:
make check
tests/runtests

This error occurs an all patforms which do not have an i386
processor.
>From GCC 3.3.2 manual:
`cdecl'
On the Intel 386, the `cdecl' attribute causes the
compiler to
assume that the calling function will pop off the stack
space used
to pass arguments. This is useful to override the
effects of the
`-mrtd' switch.
The wrong statement is in lib/expat.h line 48
#elif defined(__GNUC__)
#define XMLCALL __attribute__((cdecl))
the #elif statement has to be defined as:
#elif defined(__GNUC__) && defined(__i386)
#define XMLCALL __attribute__((cdecl))
Regards

According to the README the Check library is a pre-requisite
for building and running the test suite..

I don't think I do have it installed -- at least locate
doesn't seem to find it. But FYI, the tests, after issuing a
lot of warnings, end with this:
tests/runtests.c:1409: warning: implicit declaration of
function `srunner_run_all'
tests/runtests.c:1410: warning: implicit declaration of
function `srunner_ntests_failed'
tests/runtests.c:1411: warning: implicit declaration of
function `srunner_free'
tests/runtests.c:1412: warning: implicit declaration of
function `suite_free'
make: *** [tests/runtests.o] Error 1

Do you have the Check library installed?
If yes, which tests does it fail?

No, i think the problem was that make test is designed to
run after make install in expat. I'd never heard of this
before. But now that it is installed, it of course still
fails tests. More on the issue here:

PATH variable should point to /usr/local/ or try
using ./configure --prefix=/usr/local/lib
and read the README

True enough. I thought it was failing because `make check`
was failing spectacularly, but it turns out that the same is
true of 1.95.5, which issues no warnings. I've now tried
1.95.7 with XML::Parser, and all its tests pass, so I'm happy.
Thanks,
David

The build should still succeed. Its only a warning.

I notice I get the same results with gcc 2.95.2, gcc3 (GCC)
3.1 20021003 (prerelease), and gcc-3.3 (GCC) 3.3 20030304
(Apple Computer, Inc. build 1495). Pity.

David

Is there a workaround, in the meantime? I'm trying to get
expat built on Mac OS X 10.3 "Panther".
Thanks,
David

The same warning occurs also with gcc on Solaris. Somewhat
annoying. it might be useful to try and compile a program
during configure to see whether the cdecl works.

Does gcc on MacOSX know about cdecl at all,
or does it just not understand the attribute directive?

This was with MacOS X 10.3 Panther, with the built-in gcc.
