[squid-users] Troubles compiling latest Squid 3.5 on Windows 7 with Cygwin

[Rafael Akchurin]

Hello all,

I am struggling to compile Squid 3.5 on windows 7 x64 using latest Cygwin. 

During configuration (./configure --disable-wccp --disable-wccpv2)
The following error occurs:

checking for ldap.h... (cached) yes
checking winldap.h usability... no
checking winldap.h presence... yes
configure: WARNING: winldap.h: present but cannot be compiled
configure: WARNING: winldap.h: check for missing prerequisite headers?
configure: WARNING: winldap.h: see the Autoconf documentation
configure: WARNING: winldap.h: section "Present But Cannot Be Compiled"
configure: WARNING: winldap.h: proceeding with the compiler's result
configure: WARNING: ## ------------------------------------------- ##
configure: WARNING: ## Report this to http://bugs.squid-cache.org/ ##
configure: WARNING: ## ------------------------------------------- ##
checking for winldap.h... no
checking w32api/windows.h usability... yes

Similar with mswsock:

checking mswsock.h usability... no
checking mswsock.h presence... yes
configure: WARNING: mswsock.h: present but cannot be compiled
configure: WARNING: mswsock.h: check for missing prerequisite headers?
configure: WARNING: mswsock.h: see the Autoconf documentation
configure: WARNING: mswsock.h: section "Present But Cannot Be Compiled"
configure: WARNING: mswsock.h: proceeding with the compiler's result
configure: WARNING: ## ------------------------------------------- ##
configure: WARNING: ## Report this to http://bugs.squid-cache.org/ ##
configure: WARNING: ## ------------------------------------------- ##
checking for mswsock.h... no

If I run "make" after that it fails at start:

Is this a known issue or am I doing something wrong?
Please note the same commands compile Squid 3.3.8 (from Cygwin) without any problems.

Thank you very much!
