FreeRadius 2.1.8 doesn't compile under Cygwin 1.7.5 `_lt_libltdl_LTX_preloaded_symbols'

[José Manuel Jiménez Ramírez]

Trying to build FreeRadius from Cygwin I always have the same compilation error:


gcc .libs/radiusd.def .libs/radiusdS.o -o radiusd.exe .libs/acct.o .libs/auth.o .libs/client.o .libs/conffile.o .libs/crypt.o .libs/exec.o .libs/files.o .libs/listen.o .libs/log.o .libs/mainconfig.o .libs/modules.o .libs/modcall.o .libs/radiusd.o .libs/stats.o .libs/session.o .libs/threads.o .libs/util.o .libs/valuepair.o .libs/version.o .libs/xlat.o .libs/event.o .libs/realms.o .libs/evaluate.o .libs/vmps.o .libs/detail.o -Wl,--export-dynamic  /freeradius-server-2.1.8/src/lib/.libs/libfreeradius-radius.a -lws2_32 -lresolv -lpthread -lcrypt /usr/lib/libltdl.dll.a -lssl -lcrypto

I think that there are some problems with libtool and libltl, then searching in the mail list I made the changes said by Alan Dekok, in the src file 'freeradius-server-2.1.8\src\main\modules.c', Adding:

#define lt__PROGRAM__LTX_preloaded_symbols \
	lt_libltdl_LTX_preloaded_symbols

And in the Make.inc:
Update CFLAGS to add -DIE_LIBTOOL_DIE

But always obtain the same compilation error.
I need to use a FreeRadius version which supports Sha256 as the certificate signature
Any help would be fantastic. I need to use FreeRadius under Cygwin and there isn´t a lot of information in the mailing list.



Thanks,
