Summary: Can not build expat-1.95.5.tar.gz

Initial Comment:
I have downloaded expat-1.95.5.tar.gz to my PC, which has 
cygwin installed. According to the docs, I can install like I am 
running on a UNIX machine : 
"Building under Win32
If you're using the GNU compiler under cygwin, follow the Unix 
directions in the next section. Otherwise if you have Microsoft's 
Developer Studio installed, then from Windows Explorer double-
click on "expat.dsp" in the lib directory and build and install in the 
usual manner."

After running configure, I run make and got the following error:
"$ make
/bin/bash ./libtool --silent --mode=link gcc -g -O2 -Wall -Wmissing-
prototypes -
Wstrict-prototypes -fexceptions   -I./lib -I. -no-undefined -version-
info 4:0:4
-rpath /usr/local/lib  -o libexpat.la lib/xmlparse.lo lib/xmltok.lo 
lib/xmlrole.
lo
/usr/lib/libcygwin.a(libcmain.o)(.text+0x6a): undefined reference 
to `WinMain@16
'
collect2: ld returned 1 exit status
make: *** [libexpat.la] Error 1

"


What do I need to do to install  ? 

Attached is the configure log file.

Thanks,

Guy Adani

Hello,

The problem with Cygwin is, that we use the devel version of
libtool because libtool 1.4 is really broken (for Cygwin needs).

In the future, after libtool 1.5 or later is released and used all 
over the place there will be no more major problems like this.

Since the libtool and other autotool scripts in the original 
expat source are built using libtool 1.4.x they don't do the 
right thing for the Cygwin development chain and therefore 
all the scripts need to be rebuild with the current Cygwin 
'devel'-autotoolchain.  That is (as you can see in the patch): 

autoupdate
(cd conftools/; rm -f ltmain.sh ltconfig)
aclocal -I conftools
libtoolize --force --copy --automake
aclocal -I conftools

ltfiles=/usr/autotool/devel/share
cp $ltfiles/aclocal/libtool.m4 conftools/libtool.m4
cp $ltfiles/libtool/missing \
   $ltfiles/libtool/install-sh \
   $ltfiles/libtool/mkinstalldirs \
   conftools/

# Generate the autoconf header template (expat_config.h.in) 
and ./configure
#

${AUTOHEADER:-autoheader}

echo "Creating configure ..."
### do some work to toss config.cache?
${AUTOCONF:-autoconf}

# toss this; it gets created by autoconf on some systems
rm -rf autom4te*.cache

# exit with the right value, so any calling script can continue
exit 0


SOLUTION:
=========
Get the soucre from any Cygwin mirror or my site:
http://koeln.convey.de/cywgin/expat/expat-1.95.5-1-src.tar.bz2

There is a buildscript and a patch included which will prepare 
the source for building on Cygwin.

Also available separately:
http://koeln.convey.de/cywgin/expat/expat-1.95.5-1.sh
http://koeln.convey.de/cywgin/expat/expat-1.95.5-1.patch


HTH,

Gerrit

It seems, there is a bug in the configure script. To build 
a Cygwin DLL the '-shared' option has to be used.

Change line 4765, 4767 and 4769 from
$CC .....
to
$CC -shared .....

and start './configure' and 'make' again. Now, everything 
should work fine.
