Hi getting a stack problem here any ideas (newbie @ linux)

Would this be the patch to fix it ?
im unable to install any help please

(quote)Hey,

I tracked down the bug and it happens because of a behavioural change between Tcl8.5.9 and Tcl8.5.10.
(If you care for details: Tcl_ScanElement used to overestimate the required space, it was rewritten and apparently doesn't do that always anymore. Whether or not the terminating '\0' for strings is included in the estimate is the issue here, eggdrop's code assumes it is while the real return values of Tcl_ScanElement indicate otherwise.)

Here's a patch (patch -p1 < this.patch) to fix the issue:

Code:

[nml375]

Most likely yes.

[essexman]

but unable to install i need some help

[nml375]

Oh, sorry, missed that part of your post.
If you're not able to use the patch utility to apply the patch, try editing it by hand:
Locate the tclhash.c file located in the src directory, and open it in your favourite text editor.
Search for the word Tcl_ScanElement. You should find two occurences around line 1267 or so.
The lines should read:

Code: Select all

    l = nmalloc(Tcl_ScanElement(p, &k));

Change both lines into this:

Code: Select all

    l = nmalloc(Tcl_ScanElement(p, &k) + 1);

Compile your eggdrop in the usual manner.

[essexman]

yes i thought that to

i added this on each line " + 1 " in the correct place
but no go for me same error

[essexman]

This is the error now

Errors regarding undefined references during linking usually means that you are missing some libraries. Usually, the configure-scripts catch these though.

Moreso, the suggested patch should not trigger a linking error such as that you describe. Can you verify that the same source compiles cleanly without the patch?

[essexman]

it did compile fully before and after patch
only when i startup do i get problems

This is Eggdrop's GNU configure script.

I am getting a bit confused now, as the last error you posted was indeed a linking error, not a runtime error.

If you can successfully compile the source with the patch applied, does this fix your initial runtime error or not?

Also, now you are building 1.6.19 instead of 1.6.20?

[essexman]

ok
i have tried both with same problem error
i have just cleared all and started over again
i installed 1.6.20 got same problem after patch was added
