[gnutls-help] Not able to build gnutls3.2.1 on cygwin

[Mohan Kemparaju]

Hello Nikos,

Thank you for your reply.
Since i wanted to build gnutls and dependent libraries for a target machine
using arm, i use the arm cross-compiler from codesourcery. I was successful
is building using MinGW. Thanks for the pointer. I had to install the
pkg-config package in MinGW, which solved the problem.

Now, using MinGW, i was to build gnutls for the PC using gcc. I want the
client app using gnutls on the PC, this i need this. I use the same
code-base that was used above. I was successful in building gmp/nettle. The
.a / .dll files are generated.

With gnutls, i get an error while configuring.
My configure parameters are

$./configure --disable-cxx --with-included-libtasn1 --disable-doc
--disable-tests
CPPFLAGS=-I/c/UserData/0.0.Projects/0.1.PFS/GAD/Source/Gnutls/Library/include
LDFLAGS=-L/c/UserData/0.0.Projects/0.1.PFS/GAD/Source/Gnutls/Library/lib/
LIBS="-lgmp -lnettle -lhogweed"
 PKG_CONFIG_PATH=/c/UserData/0.0.Projects/0.1.PFS/GAD/Source/Gnutls/Library/lib/pkgconfig

I get the below error
configure : error : C compiler cannot create executables.See config.log
file for more details.

In the config.log, i see the below error, since i generate the nettle,gmp
library using gcc, i do not understand this error.
