Tcl Source Code

I run into problem with linking programmes with tcl8.5.0 because of hidden objects. The shared object tclInt.h is in tcl-devel package, but when I linked it into programme  like expect, no tclInt.h object was found. I don't know if this hidden objects are really needed. I solve this problem with patch in attachment. 

The second part of patch is about paths, because shared object can't be found with previous path.

Appears that the bugs reported
here are in Expect, not Tcl.

re (1) Or there is also Tcl_GetCommandInfo() and pull the Tcl_ObjCmdProc* from the info struct.

What's wrong with using Tcl_Eval? Direct access to Tcl command implementations is not supported.

Re (1) sure the expect needs access to object Tcl_CloseObjCmd() and Tcl_ReturnObjCmd(), but that's not possible because of hidden whole object. Changing MODULE_SCOPE on extern is hack to do these objects accessible. It was functional in previous version of tcl-8.4.15.

Re (2) it just means that it expects the unix dir to be on the include path, which is fairly reasonable.

To clarify the issues:

(1) expect seems to need access to Tcl_CloseObjCmd() and Tcl_ReturnObjCmd(), these are declared MODULE_SCOPE

(2) generic/tclPort.h has
       #include "tclUnixPort.h"
    where it should be
       #include "../unix/tclUnixPort.h"
    Does this mean we are not really using any of tclUnixPort.h on any of our tested platforms?
