I have the same problem on a combination of Mac OS X 10.4.9 + expat
(Macport version) + Intel C/C++ Compiler fo Mac.

I really don't know who this error concerns to but it seems it is related
with the Intecl C/C++ compilers more than anything else. The problem arises
because the configure script can not find memmove and bcopy. I have
extracted the code generated by autoconf to test for the presence of
memmove and tried to compile it with gcc and icc. GCC has not problems
compiling it which as expected means that expat can be compiled with gcc
without any trouble.

However, ICC (Intel compiler) can not compile the code which means that
the configure test will fail and memmove is considered as not present in
the system which in turn triggers compilation errors.

autoconf uses the following compiler options to compile the test code:

icc -o conftest -Wall -Wmissing-prototypes -Wstrict-prototypes
-fexceptions ac_check_memmove.c

And according to my research -fexceptions is the option making icc to
fail. According to gcc documentation the -fexceptions option can make gcc
to link the code to libstdc++ even when it is not a C++ program. However,
it seems that icc does not do the same and outputs the following messages:
ac_check_memmove.c(49): warning #310: old-style parameter list
(anachronism)
  char memmove ();
       ^

ac_check_memmove.c(49): warning #1419: external declaration in primary
source file
  char memmove ();
       ^

ac_check_memmove.c(67): remark #111: statement is unreachable
    return 0;
    ^

ld: Undefined symbols:
___gxx_personality_v0

The undefined symbol ___gxx_personality_v0 is, not surprisely, found at
the libstdc++ library which is automatically included by gcc (trigger by
the -fexceptions option) but not included by icc. If the option -lstdc++ is
given manually to icc then the compilation succeeds.

I think this explains the error and a quick solution for compiling expat
will be adding -lstdc++ to the LDFLAGS environment variable at
configuration time.

LDFLAGS="-lstdc++" ./configure --prefix=/path/to/

wiesmann, please let us know if it was your
build environment's fault so we know if we
can close the bug. Thank you!

I'm on an intel mac, too (see above).

You might want to consider running a selfupdate via 'sudo port selfupdate'
to get MacPorts 1.4.3. The portfile itself basically hasn't changed for
nearly a year, but the base-code has (significantly).

Also, make sure you have the latest version of the Developer Tools
installed, (on an intel mac the output of 'gcc --version' should be:
i686-apple-darwin8-gcc-4.0.1 ... build 5367)

I am using Mac ports (MacPorts 1.320). I know that expat builds correctly
on PPC machines, as I use it on my G4 Powerbook.

works fine on my mac (Mac OS X 10.4.9, i386-apple-darwin8.9.1, latest
version from cvs, developer tools 2.4.1)

/bin/sh ./libtool --silent --mode=compile gcc -std=gnu99 -I./lib -I. -g

Have you tried the MacPorts port for Expat?
