| Version: | 9.0.3 | ||
| Description: | ||||
tcl.h does this:
#if TCL_MAJOR_VERSION < 9
# ifndef Tcl_Size
typedef int Tcl_Size;
# endif
...
tclsqlite3.c does this:
#if TCL_MAJOR_VERSION==9
# define CONST const
#elif !defined(Tcl_Size)
typedef int Tcl_Size;
#endif
Since Tcl_Size is never defined as a macro, the #ifndef guards don't help, and pre-C11 compilers error like so:
/opt/bblocal/var/buildworker/base/build/vendor/tcl/pkgs/sqlite3.51.0/generic/tclsqlite3.c:56:15: error: redefinition of typedef 'Tcl_Size' is invalid in C [-Wtypedef-redefinition]
typedef int Tcl_Size;
^

Thanks for the report! Should be fixed [b6a50a0482cf3db3|here]. Done in Tcl, because sqlite3 won't be the only extension suffering from this when using a pre-c11 compiler. pre-c11 compilers are dying out, that's most likely the reason this wasn't reported before. apnadkarni added on 2026-04-16 11:56:45:
Re-opened because GH builds break on all platforms. apnadkarni added on 2026-04-16 11:57:57:
Closing - race condition in re-opening and fix being committed. jan.nijtmans added on 2026-04-20 11:53:26:
See also d3f41333aa, which is also an instance of basically the same bug. | ||||
