I am trying to adapt socketxx to cygwin
(http://www.linuxhacker.at/socketxx)
In addition to a lot of other problems, I have a puzzling libtool issue
make[2]: Entering directory
`/pub/devel/gdcm/socket++-1.12.13_build/socket++'
/bin/sh ../libtool --tag=CXX --mode=link g++ -Wall -g -O2
-version-info 1:2:0 -o libsocket++.la -rpath /usr/local/lib
sockstream.lo sockinet.lo sockunix.lo pipestream.lo fork.lo protocol.lo
echo.lo smtp.lo ftp.lo sig.lo
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin
shared libraries
but
g++ -Wall -g -O2 -shared -o cygsocket++-0.dll
-Wl,--out-implib=libsocket++.dll.a sockstream.o sockinet.o sockunix.o
pipestream.o fork.o protocol.o echo.o smtp.o ftp.o sig.o
Creating library file: libsocket++.dll.a
$ cygcheck ./cygsocket++-0.dll
E:\cygwin\pub\devel\gdcm\socket++-1.12.13_build\socket++\cygsocket++-0.dll
E:\cygwin\bin\cygwin1.dll
[cut]
E:\cygwin\bin\cyggcc_s-1.dll
E:\cygwin\bin\cygstdc++-6.dll
So where is the undefined symbol ??
I am already using "autoreconf -f -i" and the libtool
seems equivalent to what is working for any other package
adding LT_INIT([dlopen win32-dll shared])
to configure.in had no effect
and the Makefile.am is very basic
---------------------------------------------
INCLUDES = -I$(top_srcdir) -I$(top_builddir)
lib_LTLIBRARIES = libsocket++.la
libsocket___la_SOURCES = sockstream.cpp sockstream.h \
sockinet.cpp sockinet.h \
sockunix.cpp sockunix.h\
pipestream.cpp pipestream.h \
fork.cpp fork.h \
protocol.cpp protocol.h \
echo.cpp echo.h \
smtp.cpp smtp.h \
ftp.cpp ftp.h \
sig.cpp sig.h
libsocketincludedir=$(includedir)/socket++
libsocketinclude_HEADERS = \
sockstream.h \
sockinet.h \
sockunix.h\
pipestream.h \
fork.h \
protocol.h \
echo.h \
smtp.h \
ftp.h \
sig.h
libsocket___la_LDFLAGS = -version-info @LIBSOCKET_SO_VERSION@
-------------------------------------------------
Any idea about what I should look for ?
