Yes. The internals of a DIR structure differ on almost every platform. RPM is emulating a DIR structure internally as well as passing through a pointer opaquely to whatever structure the operating system is using when necessary. So this code "breaks" for every new platform (RPM on Cygwin hasn't been attempted for years afaik). If you can send along a copy of <dir.h> and tell me what #define you are using to identify CYGWIN during build time, I can ;likely send you a patch. What mostly needs doing is examining areas of the code like this: #if !defined(__DragonFly__) && !defined(__CYGWIN__) dp->d_reclen = 0; /* W2DO? */ #endif #if !(defined(hpux) || defined(__hpux) || defined(sun) || defined(RPM_OS_AIX) || defined(__CYGWIN__) || defined(__QNXNTO__)) #if !defined(__APPLE__) && !defined(__FreeBSD_kernel__) && !defined(__FreeBSD__) && !defined(__NetBSD__) && !defined(__DragonFly__) && !defined(__OpenBSD__) dp->d_off = (off_t)i; #endif dp->d_type = dt[i]; #endif /*@=type@*/ and adding CYGWIN to the pile. Note that rpmio/fts.[ch] has similar (but not quite as bad) portability breakage. Could you also add a bug at http://launchpad.net/rpm please? I will then create a blueprint and attach the bug and then plan out milestones->implementations->releases for getting RPM to compile and "work" on cygwin.
