[squid-users] Compiling Squid under Cygwin

[Yakovlev, Vadim]

Hello all,

I'm trying to compile Squid 3.5.10 for Windows with Cygwin, and ran into number of problems. Some I was able to resolve, but finally stuck at compiling negotiate_sspi_auth helper. In particular, I get "error: 'SSP_blobP' was not declared in this scope" in negotiate_sspi_auth.cc. The only place I've found where SSP_blobP type is defined is sspwin32.h, and it is defined only if _SQUID_WINDOWS_ macro is also defined:

#if _SQUID_WINDOWS_
...
typedef char * SSP_blobP;
...
#endif /* _SQUID_WINDOWS_ */

But _SQUID_WINDOWS_, which may be defined in osdetect.h, is not defined if we are on Cygwin:

#elif defined(__CYGWIN__)
#define _SQUID_CYGWIN_ 1

#elif defined(__MINGW32__) || defined(__MINGW__)
#define _SQUID_MINGW_ 1
#define _SQUID_WINDOWS_ 1

#elif defined(WIN32) || defined(WINNT) || defined(__WIN32__) || defined(__WIN32)
#define _SQUID_WINDOWS_ 1

Since on Cygwin macro __CYGWIN__ is defined, then only _SQUID_CYGWIN_ becomes defined, but _SQUID_WINDOWS_ is not. There are places in Squid code which are processed only when both _SQUID_CYGWIN_ and _SQUID_WINDOWS_ are defined, so as an experiment I've tried patching osdetect.h to make _SQUID_WINDOWS_ also defined when compiling on Cygwin, but that immediately produced hell of new errors during make: unresolved references, conflicting function declarations, etc.

So does anybody has an idea, how that should be corrected?
