Hello,

I am trying to build the latest ROHC source (2.2.0) on both Linux and Windows. I am able to build it fine on Ubuntu 18.04 and use it. But when I to try to build it on Windows 10 with Cygwin, the build is failing with the following errors:

 -------------------------------

---------------------------------------------
I see that these symbols have not been exported with ROHC_EXPORT as they are declared 'static'. Is this a known issue for Windows 10?. Please let me know if there is any solution/workaround for the same. 

Also, during 'configure',  I see the following warnings (which I guess is not related to the above issue) : 
checking winsock2.h presence... yes
configure: WARNING: winsock2.h: present but cannot be compiled
configure: WARNING: winsock2.h:     check for missing prerequisite headers?
configure: WARNING: winsock2.h: see the Autoconf documentation
configure: WARNING: winsock2.h:     section "Present But Cannot Be Compiled"
configure: WARNING: winsock2.h: proceeding with the compiler's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to https://rohc-lib.org/ ##
configure: WARNING:     ## ------------------------------------ ##
checking for winsock2.h... no


Thanks,
Vinod
