Trying to "back out" a little to maybe see the big picture I ran cmake again,
first just "cmake .." for a base line, then including zlib support to compare
to the base line:
cmake .. -DENABLE_ZLIB_COMPRESSION=ON
-DZLIB_LIBRARY=../../zlib-1.2.11/myBuildOrig/Debug/zlibstaticd.lib
-DZLIB_INCLUDE_DIR=../../zlib-1.2.11
There is a difference in the cmake output that puzzles me. Without zlib support
I'm seeing this:
...
-- Performing Test HAVE_IOCTLSOCKET
-- Performing Test HAVE_IOCTLSOCKET - Success
-- Looking for include file arpa/inet.h
-- Looking for include file arpa/inet.h - not found
...
With zlib enabled the output changes to:
-- Performing Test HAVE_IOCTLSOCKET
-- Performing Test HAVE_IOCTLSOCKET - Failed
-- Performing Test HAVE_IOCTLSOCKET_CASE
-- Performing Test HAVE_IOCTLSOCKET_CASE - Failed
-- Performing Test HAVE_SO_NONBLOCK
-- Performing Test HAVE_SO_NONBLOCK - Failed
-- Looking for include file arpa/inet.h
-- Looking for include file arpa/inet.h - not found
As a result, the header file libssh2_config.h is different, without zlib
support it contains these lines:
/* Socket non-blocking support */
/* #undef HAVE_O_NONBLOCK */
/* #undef HAVE_FIONBIO */
#define HAVE_IOCTLSOCKET
/* #undef HAVE_IOCTLSOCKET_CASE */
/* #undef HAVE_SO_NONBLOCK */
/* #undef HAVE_DISABLED_NONBLOCKING */
With zlib enabled this same section in libssh2_config.h changes to:
/* Socket non-blocking support */
/* #undef HAVE_O_NONBLOCK */
/* #undef HAVE_FIONBIO */
/* #undef HAVE_IOCTLSOCKET */
/* #undef HAVE_IOCTLSOCKET_CASE */
/* #undef HAVE_SO_NONBLOCK */
#define HAVE_DISABLED_NONBLOCKING
Otherwise the files are identical. Could that be why I'm getting stuck in
recv()?
