Re: best embedded ssl for libcurl and howto

I still find the same for polarssl on web page:
http://curl.haxx.se/docs/install.html

In

 MORE OPTIONS
   ------------

*To build with yassl support instead of OpenSSL or GnuTLS, you must build
     yassl with its OpenSSL emulation enabled and point to that directory root
     with configure --with-ssl.

     To build with NSS support instead of OpenSSL for SSL/TLS, note that
     you need to use both --without-ssl and --with-nss.

     To build with PolarSSL support instead of OpenSSL for SSL/TLS, note that
     you need to use both --without-ssl and --with-polarssl.

     To build with axTLS support instead of OpenSSL for TLS, note that you
     need to use both --without-ssl and --with-axtls.

     To get GSSAPI support, build with --with-gssapi and have the MIT or
     Heimdal Kerberos 5 packages installed.*

I have also observed that while cross compiling libcurl for my embedded
platform i gave path of polarssl cross compiled for my platform but while
building my project polarssl gave linking error like this:

./curl/libcurl.a(libcurl_la-polarssl.o): In function

collect2: ld returned 1 exit status

then i included polarssl in my project and gave path of that in my make
file.

so what was the use of giving path while cross compiling the libcurl. I was
expecting that including libcurl library to my project should be enough to
work out with ssl. but have to include polarssl similar to libcurl.

anyone know why??

Thanks
