First off: I've only just looked into SQLite, and I'm impressed; it's a great, convenient tool with a feature set that hits a sweet spot between functionality and simplicity for a number of uses. I had just one problem when using it from C++ code on Solaris with Sun's compiler. (I suspect one of my other compilers would diagnose it too.) This patch doesn't look to be quite right against current CVS, but for Version 3.3.10 I've made this change to sqlite.h to fix a type error relating to linkage (which is diagnosed, though only as a warning, by Sun CC) which is present when using sqlite.h from C++ code. (The same change would apparently apply to sqlite3.h.in in the CVS tree.) SQLite still builds with this change; I've not been able to run the Tcl-based test suite. On a related but separate note, is there any standard that guarantees that casting -1 to a function pointer type is reasonably portable? My experience is that it doesn't cause problems, but certainly it's not portable C or C++ from the viewpoint of the language standards. That's a separate issue though. The portable way would be to provide a real function for SQLITE_TRANSIENT to point to, but still have it recognized as a special case. Would there be any interest in a patch to make that change?
