So one binary could possibly be used for all Tcl versions from 7.6 > up to 8.4 . I'm hate tcl stubs :)) And I have tcl 8.0, 8.2 and 8.3 installed simultaneously almost anywhere and don't want autodetect. Yours approach ok for Pgtcl - because you load pgtcl into running tcl interpreter, but with pl/tcl you load pltcl.so and it as dependency loads tcl library, so stub library needs to select "best" tcl version to load :)) > The only useful change to configure.in I could think of is to issue a > warning if configure is called without --enable-multibyte and > --enable-unicode-convertion , but the available Tcl is >= 8.1 . ok, for now I do it at compile time, based on TCL_MAJOR_VERSION & TCL_MINOR_VERSION
